Q&A   p. 30


Q. What is the best paint for windows, doors and architraves on the interior and exterior? Would it be low sheen or flat? The interior is good condition enamel, about 20 years old. The exterior varies from good to poor condition and needs sanding, fill, and prime/undercoat.

A. Old enamel paint can be difficult to prepare to achieve adhesion of a new paint system. Ensure the existing enamel is clean and free from grease etc. then thoroughly sand to profile for recoating. Then apply a full coat of Resene Quick Dry primer undercoat and finish with two coats of Resene Lustacryl.

Dark colours may cause the rapid drying of damp timber with the ensuing danger of warping, though this effect will be lessened when a Resene CoolColour™ is selected in place of a standard colour. The CoolColour topcoat will not render the painted surface cool to touch but the Cool Colour version will reflect more heat than the same colour made on non-cool technology.

Q. I am looking for a white paint suitable for applying to a textured fibreglass surface of approximately 15sqm that is part of a roof and open to all weather. Ideally we would like something which resists lichen growth as that has been a problem with the current paint. The finish can be anything from matt to gloss, but a semi-gloss or satin would probably be most aesthetically pleasing.

A. There are no additives that can be added to a paint to control lichen growth on a painted surface. The easiest way is to spray the roof with Resene Deep Clean diluted and used to label instructions at the beginning of spring and autumn and then leave nature to do the hard work.

March 2019

Q. I'm presently cleaning down (waterblasting) three concrete water tanks on our local Golf Course. They have cracks that are seeping but these will be sealed. Two of them have previously been painted and the other is bare concrete. I have recently finished painting my house with Resene X-200 and question if that could be used on the tanks as it is user friendly paint. I realise the 'bare tank' will require to be sealed first or maybe not if using Resene X-200.

A. Yes if the leaks are fixed, prime bare concrete with Resene Sureseal then apply three coats of Resene X-200. If there are signs of bio growth, mould/algae, then treat these areas with Resene Moss & Mould Killer diluted and used to label directions.

The Resene X-200 system will give a durable decorative paint system.

March 2019

Q. How do I paint a metal front door in a sea spray zone? I think its powder coated at the moment and is in good condition - no pitting, paint peeling or rust - just not a very nice colour.

I have painted my tin garage roof and walls with a spray gun and Resene Hi-Glo paint but the door isn't at my house, it's at a friend's house and she's concerned the sea spray would affect a painted door.

A. Wash down using Resene Roof and Metal Wash diluted and used to label directions, lightly sand with 400 grade sandpaper to profile the powder coated surface. Apply two coats of Resene Galvo-Prime and finish with two coats of Resene Lustacryl.

We recommend the Resene CoolColour™ version of the Resene Hi-Glo be used if selecting a dark topcoat colour. The CoolColour topcoat will not render the painted surface cool to touch but the CoolColour version will reflect more heat than the same colour made on non-cool technology.

March 2019

Q. I have some rust spots (staining) coming through a painted handrail. I would like to paint over the handrail with the same colour as our house is painted. How should I treat the rust?

A. We don't recommend 'painting‘ over rust spots as this does not address the cause.

Typical preparation for this situation is as follows; Scrub down using Resene Roof and Metal Wash diluted and used to label directions. Rinse clean or hose down with fresh water ensuring all salts are also removed.

All paint that is flaking or unsound must be removed by using mechanical methods e.g. 3M Rust and Paint Removal Disc, taking care not to damage either the substrate or the surrounding areas.

Remove all areas of white corrosion material and as much red rust as is practicable and all paint that is flaking or unsound must be removed by using mechanical methods e.g. 3M Rust and Paint Removal Disc,  taking care not to damage either the substrate or the surrounding areas.

Where under-film corrosion is taking place, the existing paint must first be removed as above and remove under film corrosion products taking care not to damage sound zinc coated areas. All paint edges must be feathered to a smooth finish.

Note: The performance of the subsequent paint systems will be largely dependent on the thoroughness of this surface preparation stage.

Ensure all edges of damaged paint are sound and immediately spot prime all areas of corrosion and any other bare metal with a full coat of the specified primer.

March 2019

Q. I require a black tinter to add to creosote.

A. Creosote should penetrate into the timber substrate, if you add bulk colorant this will not be absorbed to any extent and has the potential to remain on the surface and weather away relatively quickly, so the original blackness intensity may disappear relatively quickly, especially on the northern elevation.

March 2019

Q. I need paint to waterproof the concrete pavement and concrete brick wall of my carport, so water doesn't seep through into the carport when it rains.

A. The best way to fix this is to make the exterior face of the blockwork weathertight by applying our Resene X-200 system, however if the exterior wall is back filled then this is not possible.

We have no system to waterproof the pavement but Resene HydraBlock may be applied to the interior face if access to the exterior face is not possible.

March 2019

Q. Can Resitex be applied over mill finish aluminium cladding?

A. Yes as long as the aluminium is primed with Resene Galvo One.

March 2019

Q. We are putting in a macro cooktop bench top inside and want to know what you recommend to seal it with.

A. For a clear coat system to achieve a water resistant clear finish, use four coats of Resene Polythane, and envelope seal with at least two coats.

March 2019

Q. I am a do-it-yourself home owner. I am not a novice painter and have had good results in the past.

I am painting the ceiling of my living room/dining room. The area is 9.5m x 5m. The long wall is north facing, with floor to ceiling windows supplying a lot of light. It has been undercoated twice with Resene Broadwall sealer and covered with Resene ceiling paint. I have used a roller and the correct sleeve. I had no trouble with the undercoats. However, with the topcoat, most of the joins are obvious in certain light. There is also a slight roughness to texture of the paint at the joins. I have recoated, but the joins are still obvious. Because of same colour on same colour and the glare, I found it quite difficult to see as I painted the topcoat. I enquired if the heat is a factor and if drying the paint before returning to paint the next segment and work it into the previous segment, or I am not using enough paint, or I am doing something else wrong.

A.    What you are battling is critical lighting.

The issue with joints is probably is a result of sanding of the stopped joints, resulting in furring of the paper face at the paper/stopping overlap. Suggest using a fine sandpaper grade to denib the areas showing the defects then apply 1 or 2 coats of Resene Broadwall Surface Prep and Seal to the affected areas (maybe best to coat the entire ceiling) then finish with two coats of Resene SpaceCote Flat.

March 2019

Q. How much more paper will I need to hang a horizontal striped paper diagonally?

A. We generally recommend allowing about 20% extra wallpaper.

April 2019

Q. I have chemically stripped a 44 year old hot dipped galvanised handle rail with round balusters. It was previously coated with oil based primer, undercoat and high gloss house paint. The surface is now right back to the aged zinc which is in good condition without rust. This is something I don't want to prep and repaint for a long time! Clearly my preference is not to have to deal with two pack products but will do if I really have to. I have used Resene Enamacryl for topcoats on wooden doors in the same area. These have survived really well. What are my options please?

A. Nice job on stripping back the old coatings. Two pack products are always the most durable, however if your preference is not to use two pack, and you've had good success with Resene Enamacryl, then the system below will give you good durability and be easy to touch up over time also.

May 2019

Q. In the past 20 years we have painted our wooden Fraemohs house three times with an oil-based Resene wood stain (colour light oak). I have just mistakenly bought 10 litres of the water-based version of this stain. Can I apply this on top of the oil-based stain? What preparation do I need to do? It's too large an area to sand and I'm worried about 'peeling'. I've been very happy with the 20 year results of the oil-based stain and wonder whether I have wasted my money and should just go back to buy the oil-based one, although my budget really would make that difficult.

A. Applying the waterborne version of Resene Woodsman over the oil based version is fine and you will achieve a good finish. A normal clean down with Resene Paint Prep and Housewash prior to staining is all that's required prior to applying the new stain. Take care not to apply too much as staining is better applied in thinner coats.

May 2019

Q. What paint do I use to seal external new fibrolite please?

A. The recommended Resene primer for new exterior fibre cement is Resene Concrete Primer.

May 2019

Q. I'm looking for paint that gives a concrete colour and texture. The substrate is an in situ concrete wall, but it has been skimmed, filled and repaired in areas giving it a patchy look. I'd like to find paint that I can use that still looks like concrete, but will give me a much more uniform finish.

The wall is in a basement car park, so while not exposed directly to weather, it probably needs to be considered external.

A. We recommend Resene Sandtex tinted to Resene Quarter Delta.

May 2019

Q. I bought deep grey Resene Concrete Stain and have tried two coats but it is a bit dark and uneven. I am applying it on the concrete block walls in the garage. The walls are in good condition but from the 1960s and there is an area that has some oil. What should I use to prepare this area? Can you apply just one coat or do you need a clear coat and does it need restaining every year?

A. It is not easy to achieve a uniform colour when applying Resene Concrete Stain to a vertical surface, as the product viscosity is designed for application to a horizontal surface. The solvents in the stain can re dissolve the oil which may well change the appearance when the stain is applied over an area contaminated with oil.

There is no way that the oil staining can be stabilised or disguised when staining.

May 2019

Q. I want a polished concrete 'look' for the walls and floors in my bathroom. Do you have such a product?

A. The polished look is achieved by diamond grinding/polishing of the concrete and then application of a clear coating.  For the clear finish we recommend Resene Concrete Wax.

May 2019

Q. I have small sleepout which is 5x8m and was built in 2000 with Shadowclad® that has never been stained or painted. What do I use to protect the cladding which is still in good condition? I live 50 metres from the sea. It has certainly greyed and I had it chemically washed 4 months ago. The bottom baseboards which I closed in under the dwelling, need another scrub, but it's the Shadowclad® I really want to paint or stain as I am not young and want whatever I do to see me out.

A. Ensure the surfaces are free of mould and then apply a coat of Resene TimberLock, wipe excess at time of application and leave to cure for at least 48 hours then apply a full coat of Resene Wood Primer. Then apply two coats of Resene Sonyx 101 semi-gloss or Resene Lumbersider (low sheen). If selecting a dark colour, use the Resene CoolColour™ version of the colour. The CoolColour topcoat will not render the painted surface cool to touch but the CoolColour version will reflect more heat than the same colour made on non-cool technology. Dark colours may cause the rapid drying of damp timber with the ensuing danger of warping, though this effect will be lessened when a CoolColour is selected in place of a standard colour.

Staining will be a high maintenance option; you may have to re-stain every couple of years. The system given is our best shot at a long term coating system.

May 2019

Q. Which Resene Paint product is best suited for a high-traffic concrete floor, in an entrance way that is partially exposed to the weather?

A. Resene Non-Skid Deck & Path.

May 2019

Q. I have a house that is covered in dust from the driveway, which wasn't gravelled immediately after construction. The dusty cedar cladding stain is light coloured. Is Resene Paint Prep and Housewash ok to clean this with?

A. You can use Resene Paint Prep and Housewash to try and remove the dust, however we cannot say that it will be effective and if the dust contamination has occurred while the stain was fresh, then it may have become attached/embedded to the stain and difficult to remove.

May 2019

Q. I have used an alkyd exterior wood primer on an exterior pergola on areas where I have needed to sand down to the timber surface. The remainder of the pergola is painted in waterborne paint. Can I use the waterborne paint over the primer once dried?

A. Resene Wood Primer can be over coated with Resene waterborne topcoats.

May 2019

Q. I'm wondering how to paint the Hardiplank® exterior of our house. It was built in the 1970s and was repainted about 5-10 years ago. The paint is in good condition but I don't like the colour. I would like to use Resene Sea Fog but I'm unsure exactly which Resene paint to use on Hardiplank®.

A. Wash down using Resene Paint Prep and Housewash diluted and used to label directions, apply a full coat of Resene Quick Dry then two coats of Resene Sonyx 101 tinted to the required colour.

May 2019

Q. Can you paint a house clad with Hinuera Stone, and if so, what is the process and what colour would you recommend to make it look trendy?

A. Resene does not recommend painting Hinuera stone claddings. The stone is cohesively weak and while painting can be achieved, the paint film will, more than likely peel from the surface at a later date.

May 2019

Q. I have some timber steps leading up to a balcony, which were painted many years ago; there is no apparent rot but the paint has flaked significantly. I intend to remove algae, sand and apply Resene TimberLock. I was thinking of applying Resene Quick Dry and then a bitumen waterproof membrane. Then I'd apply Resene Membrane Primer followed by Resene Sonyx 101.

Firstly, do you think a bitumen membrane is overkill? Would Resene TimberLock and using a solventborne wood primer be adequate? Water does pond on the steps when it rains.

Secondly, I noticed that Resene TimberLock has dibutyl phthalate in it from the SDS. Is this plasticiser going to cause problems with applied to waterborne coatings and the bitumen membrane?

A. What is the timber? Bituminous membranes can be but are not usually applied to timber substrates. Treat mould/algae with Resene Moss & Mould Killer diluted and used to label directions.

Wipe excess Resene TimberLock at time of application and leave to cure for at least 48 hours before applying a full coat of Resene Wood Primer. Then finish with two coats of Resene Walk-on.

May 2019

Q. I have some unopened Resene Lumbersider paint, 18 years old, stored for painting a rental property. It's time to finally paint it so will the paint be okay?

A. Not a common situation I must say. The paint technology that we were using when the paint was originally made has now been upgraded to achieve improved exterior durability. Suggest that you take the pail to a Resene ColorShop and ask them to put the pail on the store shaker.

Open the can and if it is homogeneous and contains no bits, or if the paint smells off (unwashed sports socks odour) then the paint would not be suitable for use.

May 2019

Q. Could you advise about how to remove a few dried spatters of Resene Sureseal pigmented sealer from light switches and other fittings?  The walls and ceiling were prepped only about two weeks ago.

A. Our only suggestion would be careful use of Resene Graffiti Cleaner. We cannot give any undertaking that the use of the product will not affect the substrate.

May 2019

Q. l want to paint my plasterclad house, what type of paint do you recommend? Which one is better Resene Sonyx 101 or Resene X-200?

A. As long as there are no weathertight issues, and the paint system is sound, then I would recommend two coats of Resene X-200. Prepare the surfaces by a wash down using Resene Paint Prep and Housewash diluted and used to label directions.

If there are any areas showing mould/algae infestation, treat these with Resene Moss & Mould Killer diluted and used to label directions then Resene Paint Prep and Housewash also diluted and used to label directions.

May 2019

Q. We are repainting our weatherboard home, which is in an extremely rough condition. We have used a paint shaver and a sander to remove the paint and then undercoated, filled, sanded, re-undercoated and painted in Resene Double White Pointer for the main part. Resene Black White for used for the windows, both in semi-gloss. We have noticed that every little imperfection shows up in the weatherboard no matter how much we fill and sand. Is there a better undercoat that you could recommend to stop grain raising? Also, is it normal to have a not perfectly flat surface on repainted weatherboard homes?

A. Not sure what undercoat/topcoat system you have used but on average two coats of a standard paint will only give a thickness that is akin to a piece of cello tape, so will not fill to any real degree but will telegraph the base to which it has been applied.

Repairs to a multi-layered paint system where there has been removal of a section of the old paint, can be difficult to repair to a flush finish and close up or at side angles the substrate defects will be visible.

Resene Timber Surface Prep can be used to repair the surface for a flush finish.

May 2019

Q. A contractor undertaking water blasting/sealing work at a neighbouring property has left drops and splodges on a car, asphalt driveway and painted steel roof on our adjoining property. Can you advise the process and complexity of removing Resene Waterborne Aquapel and what sort of damage might be expected to paint etc?

A. Resene Waterborne Aquapel is not paint but a water repellent treatment for concrete. The only way that we are aware of, is to wipe the surface with eucalyptus oil.

May 2019

Q. I've been told by my painter that the Resene Colorwood Whitewash that I want to use on my existing floorboards cannot be guaranteed not to yellow. Can you tell me if this is the case, and if so what causes it to yellow?

A. Not sure where your painter got his info from but the resin system used to make the product is a non-yellowing waterborne resin.

May 2019

Q. How do I prevent moisture penetrating a block wall, also through cement board? Would two coats of Resene Hi-Glo waterborne gloss be adequate?

A. Blockwork can be rendered weathertight by application of the Resene X-200 system to the exterior face of the blockwork. All pointing must be sound and flashings functioning as designed. Low build waterborne paint systems such as Resene Hi-Glo will not give weathertightness.

With fibre cement cementing the jointing system must be sound as jointing failure is where most water ingress issues arise from. A primer, Resene Concrete Primer and two coats of Resene Hi-Glo should render the FC weathertight.

The definition of a weathertight system is a paint system that does not allow liquid water to pass through the paint system but allows water vapour to pass both ways.

May 2019

Q. I am painting two new external fibreglass doors. I will be finishing with Resene Lustacryl. Do I need to use an etch primer or will your Resene Quick Dry waterborne primer be okay?  I don't want to be repainting in a few years.

A. Degrease using Resene Roof and Metal Wash diluted and used to label directions and then sand using 380 grit sandpaper, dust off and apply a coat of Resene Quick Dry followed by the two coats of Resene Lustacryl. Use the Resene CoolColour™ version of the topcoat colour if selecting a dark topcoat colour. The CoolColour topcoat will not render the painted surface cool to touch but the CoolColour version will reflect more heat than the same colour made on non-cool technology.

May 2019

Q. Can I paint ceramic splashback tiles in a kitchen successfully? They are large tiles 15cm x 15 cm and currently navy blue.  

A. If you can maintain hand contact on the tiled area when the elements close to the tiles are at full heat, then yes.

May 2019

Q. We have been asked to find a colour in your epoxy two pot range. We are having a steel pole galvanised then it is to be treated with your epoxy. Is there a choice of colours?

A. Resene Armourcote 510 high build epoxy can be tinted to a range of Resene colours, however we do not recommend epoxy coatings be left exposed to direct weathering as the epoxy coating will undergo surface chalking. To address this, we always recommend topcoating the epoxy with Resene Uracryl 400 Series topcoats.

May 2019

Q. What is the best paint for a garage floor?

A. Resene Aquapoxy is excellent for concrete garage floors, however the most important part of coating a garage floor is the preparation.

This almost always requires the concrete surface to undergo diamond grinding to remove surface contamination and provide a key for the new coating. If not prepared properly there will be problems with ‘hot tyre pick up', which is where you drive in and park your car and the hot tyres lift the coating from the surface. This is very common if floors aren't prepared correctly.

May 2019

Q. I used Resene X-200 for the original coat of paint on my plaster on brick house 10 years ago. The original paint is still in good condition. Do I use X-200 again or a different topcoat?

A. If all in good condition then yes, Resene X-200 would be ideal again. Ensure you clean down suitably prior to painting.

May 2019

Q. We are building a house with an internal concrete slab that will eventually be polished up for the kitchen/living area. Is there something that we can use to protect it from spills etc in the short term that won't make it difficult to grind at a later date?

A. A couple of coats of Resene Concrete Wax is probably the best option here as it's easy to apply. While the data sheet says to thin the first coat it may be best to apply it unthinned so it doesn't penetrate the surface too much.

Given that the floor won't be prepared prior to application, we can't give any guarantees on how long it will last and you may need to touch up in high traffic areas (easy to do this). Make sure the floor is dust free prior to applying.

May 2019

Q. I am looking at staining my new deck that was added on to an existing deck. The current deck is stained a darker, redder colour - we are looking at staining the entire deck including the already stained deck, a lighter colour. Any ideas on how we may go about this?

A. It's difficult to match old and new timber, particularly when the older area has a much darker/redder stain on it. You won't be able to just stain over to achieve this.

You may want to trial an area to see if you can remove the existing stain by scrubbing with Resene Timber and Deck Wash. It can often remove excess stain from a surface. If successful, you'll get a much more even appearance when you re-stain.

May 2019

Q. I am looking for a paint system that will adhere to commercial grade lino; it is for toilets in a town hall of moderate use.

A. Painting old lino can be a challenge and for commercial type situations, I would advise that you may end up needing to touch up or repaint the floor regularly as we can't guarantee adhesion of a paint system over old lino.

The best system we have is to apply a seal coat of Resene Waterborne Smooth Surface Sealer and leave to cure for 48 hours then apply two coats of Resene Walk-on followed by a seal coat of Resene Concrete Wax.

We'd suggest a test patch is done to confirm adhesion of the Resene Waterborne Smooth Surface Sealer. Ensure the lino is washed down using Resene Paint Prep and Housewash diluted and used to label directions before priming.

May 2019

Q. What is the best way to get an even flow with deck and path paint?

A. If rolling out, you'll want to ensure you work in a methodical and uniform manner (typically along the entire length of a board or two if painting a deck) ensuring you keep a wet edge on the paint you have just applied while you roll the next areas so they blend in. You should ensure also, that you aren't painting in direct sunlight as this will have the paint dry extremely quickly and show roller/brush marks.

Ensure you are using a No.1 Roller sleeve (8mm Dacron) if rolling.

May 2019

Q. What type of paint would be best for using on a guitar?

A. It is my understanding that high gloss clear varnishes or paints are traditionally used for guitar coating. Resene Super Gloss would be the solid paint colour with the highest gloss level and hardness.

June 2019

Q. I'm looking to repaint the bedrooms in our house a white colour again. I have done the exterior and have a lot of left over Resene Quick Dry undercoat. Is it ok to use this on the interior?

A. Resene Quick Dry can be used as a primer/undercoat for both exterior and interior applications.

June 2019

Q.  I would like to paint our house interior Resene Double Alabaster so it is bright and airy. My current house is Resene Half Sea Fog which can look a little dirty when it shadows. The paint has said that they may need an extra coat of if the colour is from the Resene Alabaster range. Is this true? Is there an alternate colour you can recommend?

A. We have looked at this over many years, if the colour is applied at the correct spreading rate there is no coverage issue. Additional coats may be required if application is over a dark existing colour. If the painter is concerned then he can apply a coat of Resene Quick Dry before the two coats of topcoat.

June 2019

Q. I have a 17 year old powder coated garage door that's faded. Will Resene Lumbersider be the right paint? Do I have to prime it first? It's not rusty or damaged.

A. Scrub down using Resene Paint Prep and Housewash diluted and used to label directions, to achieve a chalk free surface. Apply a full coat of Resene Pre-Coated Steel Primer then finish with the two coats of Resene Lumbersider colour.

June 2019

Q. I want to paint a stencil onto my double glazed glass door. Which paint would be the best and am I able to clean it off if I decide I don't like the effect.

A. We recommend two pack Resene paint for glass, the paint achieves very strong adhesion and would not be easy to remove.

June 2019

Q. I need a clear coating for an interior timber dining table that I can preferably spray on as I have spray equipment. It needs to be clear with no amber effect.

A. We recommend the Resene Uracryl 400 Clear system. Apply a seal coat of Resene Uracryl 403 UVS Clear then finish with any of the Resene Uracryl 400 Series UVS Clears.

June 2019

Q. As a member of Men's Shed, I have a community project to repaint a child's therapy toy which is used at a playgroup of Downs Syndrome children. The 'pegs' and the board need to be painted using child safe paint. 

Can you advise if the paint in the Resene testpots is suitable for this application or of a more appropriate product? I will need seven different colours, a small amount of each - a testpot would be enough. 

A. Resene testpots are filled with one of our Environmental Choice Approved NZ paints, so yes to your question.

After painting, leave for a couple of weeks to fully cure then wipe down with a cloth and warm water before placing into use.

June 2019

Q. What is the best acrylic paint type for internal walls, wet and non-wet areas? Also, what is the best paint type for internal trim, skirting, architraves, window sill and frames and for steps, oil or acrylic? I need something durable to withstand hard wearing knocks and bumps, even splashes and a little moisture in the bedrooms, hall ways, lounges and kitchen.

A. Best waterborne paint for walls in non-wet areas, Resene Resene SpaceCote Low Sheen or Resene SpaceCote Flat, for wet area (bathrooms) is Resene SpaceCote Low Sheen Kitchen & Bathroom or Resene SpaceCote Flat Kitchen & Bathroom.

The best waterborne paint for skirtings/doors etc. is Resene Lustacryl, for wet area Resene Lustacryl Kitchen & Bathroom version.

June 2019

Q. I'm after a paint that will cover fly poo. Does Resene have a paint that will do that?

A. You need to apply a solventborne sealer, Resene Sureseal then a waterborne undercoat, Resene Quick Dry. Then topcoat in your chosen Resene finish.

June 2019

Q. I'm a contract project manager (repairs/renovations). I have a client whose home experienced a fairly serious fire in their lounge, which also affected an adjacent bedroom. The painted timber window joinery survived intact but was affected by smoke, water and heat.

What is the best way to prepare and restore joinery that has been through this experience?

A. The standard prep is to remove all loose char by scraping with a tungsten blade scraper or sanding, Then seal, see Data Sheet link.

The aim of the sealing system is to prevent stain bleed into a topcoat system.

June 2019

Q. I need a paint system to apply to Corten steel to stop it corroding when it is in the ground and also when attached to a H4 treated timber post, as I understand the tanalising chemicals and the Corten react.

A. Corten steel is designed to rust, to form a protective rust shell. The manufacturer strongly advises against application of a coating system, film or non-film forming. There are no paint systems that can be used direct to rusted Corten steel to achieve corrosion control.

The only way to control the corrosion, is to abrasive basalt the Corten section to near white metal, apply a coat of Resene Armourcote 220 to achieve a dry film thickness of 75 microns then apply a build coat of Resene Armourcote 510 to achieve a dry film thickness of 250 microns. The paint system must extend at least 150mm above ground level.

June 2019

Q. I want to repaint wallboard in a bathroom. After sanding do I need a pigment sealer with two coats of Resene Kitchen & Bathroom paint or can I use two coats of waterbased enamel paint?

A. If the existing coating is enamel in good condition, thoroughly abraded, and completely clean, you could go directly on with Resene SpaceCote Low Sheen (waterbased enamel). You can use the Resene SpaceCote Low Sheen Kitchen & Bathroom for added anti-bacterial.

A pigmented sealer would be recommended where the existing coating isn't in very good condition, or where there is a build-up of surface contamination (mould, grime, staining etc.) that can be difficult to clean off completely.

June 2019

Q. We have fake tile looking walls (think they are acrylic sheets maybe) in our bathroom. What would we need to paint over them?

A. Following a thorough clean down of the surface, apply Resene Waterborne Smooth Surface Sealer (adhesion primer) - allow drying for 2-3 days so that it keys into the surface. Test a small area first to make sure that it does adhere well.

Then apply two coats of Resene Lustacryl (semi-gloss waterborne enamel).

June 2019

Q. I have a pine stairway balustrade about 40 years old. I've stripped the polyurethane off it and I intend to paint it. What undercoat and topcoats should I apply?

A. For a waterbased system, we recommend one coat Resene Quick Dry primer and two coats Resene Enamacryl (gloss waterborne enamel).

June 2019

Q. I am about to install H3.2 plywood (with green tinge) and batten cladding to my house. I want to paint a top colour of Resene Bokara Grey. Can you clarify what I should be using for all preparation and top paint coats for this application please?

A. Prime using Resene Quick Dry primer and topcoat using Resene Lumbersider Resene CoolColour™ version in your chosen colour – Resene Bokara Grey.

June 2019

Q. We are painting old seating at a bowling club.  Can we use Resene Sonyx 101 waterborne semi-gloss exterior/interior on them?

A. As a topcoat for benching/seating Resene Sonyx 101 is relatively soft, we recommend using Resene Lustacryl if you want a waterborne semi-gloss finish as Resene Lustacryl cross links to a harder film than Resene Sonyx 101.

June 2019

Q. Looking for a non-slip deck paint water based texture to go over aluminium.

A. We recommend Resene Non-Skid Deck & Path. Degrease the bare aluminium first, then prime the aluminium with a coat of Resene Galvo One.

If the aluminium is smooth/shiny wet abrade using 220 Wet and Dry sandpaper.

June 2019

Q. I am looking for some paint to use a chipboard floor for two medium size bedrooms and a medium size lounge.  Can you recommend a product?

A. If new chip board, apply a primer coat of Resene Quick Dry and finish with two coats of Resene Lustacryl.

June 2019

Q. I would like to paint my fence. It is treated pine and has a lot of mould, but is otherwise in good order. I would like to know how to clean it, removing the mould, prior to painting, and any other preparation for painting. Also I would like a recommendation for paint to use including any primer or undercoat you might recommend.

A. Treat with Resene Moss & Mould Killer diluted and used to label directions. Prime with Resene Wood Primer and two coats of Resene Lumbersider.

June 2019

Q. Might be a random question, but when rolling paint how do we ensure we get that classic ‘orange skin' texture.

I have done a patch job and whenever we paint over it, the paint is smooth making the patch obvious as the wall around it has this ‘orange skin' texture.

A. Our paints are designed to achieve a smooth as possible finish. Suggest you use a Resene No.1 sleeve roll. If you apply a good wet coat then use a dry sleeve to over roll you may be able to achieve more texture. 

June 2019

Q. How long is paint good for if stored correctly? i.e. Can we keep it for a number of years for when kids put holes in the wall etc? And, if we have two half buckets, will it damage the liquid if we were to pour it into one?

A. The storage of waterborne paint requires cool well-ventilated conditions to reduce the chance of bacterial contamination. Once paint is opened and used the risk of bacterial contamination of the paint increases dramatically. 

The paint smell is the easiest way to check for bacterial contamination. If a careful sniff of the can gives an odour response similar to smelly sports socks then there will be bacterial contamination.

As long as the paints and colours are the same you can mix them.  In fact storage in a full can is better than part cans as there is less air present.

June 2019

Q. We have a very slippery brick path. Do you have an anti-slip paint that can be applied to bricks? Or any other suggestion as to a better solution? The bricks are not glazed and have no obvious algae or mould.

A. Wash down using Resene Heavy Duty Paint Prep and Oil Remover diluted and used to label instructions, allow the bricks to dry out then apply a saturation coat of Resene Sureseal and finish with two coats of Resene Non-Skid Deck & Path.

Note that if the paint profile fills with water and freezing occurs the slip resistance is lost.

June 2019

Q. I have a teak dining table (indoor) and I have sanded this right back to its natural colour and grain. I want to keep this a matte finish but also require it to withstand normal dining table duties.  Will Resene Qristal Poly-Flat work?

A. Wipe the bare teak down using a cloth and Resene Thinner No.12. Do this a couple of times using a new cloth each time and leave for 48 hours in a well-ventilated area. This is required as teak is an oil timber.

We recommend applying a seal coat of Resene Qristal Poly-Gloss first to bring out the timber colouring, and then finish with at least two coats of Resene Qristal Poly-Flat varnish.

June 2019

Q. We are converting a single garage to a utility room/laundry and have new GIB® board and an existing block wall which has a single coat of some paint done many years ago. I have the wallboard sealer but wonder if I could use this as a primer coat on the block wall.

A. We recommend Resene Concrete Primer for priming new blockwork, Resene Sureseal for old. If the block wall has an exterior face you will need to ensure that the exterior face is made weathertight.

June 2019

Q. Is Resene Concrete Clear suitable for resealing an exposed aggregate drive?

A. Resene Walk-on Concrete Clear Wet Look would be our recommendation.

June 2019

Q. We are considering a satin metallic gold finish paint system, to be applied to a new exterior old rolled galvanised standing seam roof and walls.

A. For new ZINCALUME®, the following system is required for a metallic finish: first coat Resene Galvo-Prime, second coat Resene Lumbersider tinted to the basecoat colour for the metallic topcoat colour, third coat Resene FX Metallic, fourth coat Resene Clearcoat UVS.

The clear coat will give a gloss finish and will help protect the metallic colour from UV degradation which causes colour fade.

June 2019

Q. What's the best process and products for painting wooden floors?

It's a 1970s house with unpainted chipboard in excellent condition all sanded and previously had carpets.  I am looking at painting all the floors in the house.

A. Apply a primer coat of Resene Quick Dry and then two coats of Resene Lusta-Glo (solventborne) or Resene Lustacryl (waterborne).  From a wear perspective, Resene Lusta-Glo will give a better wear profile.

June 2019

Q. We are about to purchase a home. The ceilings are either glossed painted pinex sheets or Michelangelo tiles. The walls have a variety of wallpapers. We wish to repaint the ceilings with a flat finish and to paint finish the walls. The home is 20 years old. Can you advise the best systems and prep specs to use please?

A. We need to separate wet areas, i.e. bathrooms from other looks within the house.

For the walls, the system would be a coat of Resene Vinyl Wallpaper Sealer followed by two coats of Resene SpaceCote Low Sheen, for bathrooms apply Resene SpaceCote Low Sheen Kitchen & Bathroom.

You can use Resene Zylone Sheen as the topcoat system for areas outside of wet areas, but Resene SpaceCote is a tougher finish.

Your description that the ceilings are full gloss, suggests that the paint system on ceilings may be full gloss enamel. So apply a coat of Resene StainLock  and finish with two coats of Resene Ceiling Velvet  flat for non-wet areas.  Or you could topcoat with Resene SpaceCote Flat

June 2019

Q. Is one of your anti-graffiti paints suitable for a sheen coat on a small fibreglass boat?  The boat is coated in two pack brushing polyurethane and it seems to lose its gloss a little too much (above waterline). I thought a clear gloss of your anti-graffiti might be good?

A. Degrease using Resene Heavy Duty Paint Prep and Oil Remover diluted and used to label instructions. Thoroughly sand to profile for recoating then apply two coats of pigmented Resene Uracryl 403 and finish with a full coat of Resene Uracryl 403 UVS Clear.

June 2019

Q. I've been asked to paint a yellow warning line near the edge of the roof of a building. I'm thinking Resene Summit Roof or Resene Hi-Glo. The gloss paints are harder wearing, right? But will it look funny on a faded old roof?

A. You will have to use Resene Hi-Glo as the colour Safety Yellow is not available in Resene Summit Roof. Given that it is a safety marking requirement, I would not be that worried about gloss level difference with the existing roof paint.

June 2019

Q. I used Resene Sureseal to undercoat a room. Do I need to lightly sand it before the two coats of topcoat? I have heard that it is good practice to sand between coats.

A. There is no technical reason to sand the Resene Sureseal before topcoating with Resene waterborne topcoats. However, if you have applied to sealer to new stopped plasterboard, there may be areas where paper raising has occurred and these areas can be de-nibbled by giving it a light sanding.

There is no need to sand between layers of waterborne topcoat, in fact it is difficult to sand freshly applied waterborne paint as the heat generated by sanding causes the paint to roll up.

June 2019

Q. What's the best paint to use on MDF bookshelves?

A. For bare MDF apply a primer coat of Resene Quick and then finish with two coats of Resene Lustacryl.

June 2019

Q. Can wallpaper be used in a bathroom with a shower or bath close by, or a wet area like a bathroom? Or are there certain types of wallpaper that can be used in these areas?

A. Yes you can wallpaper in a bathroom, however it comes down to ventilation. If the bathroom is prone to condensation or fogging up on a regular basis we would not recommend wallpapering as the moisture gets in behind and the paper will lift.

June 2019

Q. I have rust around the lead head nails on my roof. What is best practice to repair this? There is light rust showing in odd spots in the middle of the sheet also. Replacing the iron would be too expensive.

A. Wash down using Resene Roof and Metal Wash diluted and used to label directions. Remove loose corrosion/rust deposit using a 3M Rust and Paint Removal Disc and spot prime these areas with two coats of Resene GP Metal Primer before topcoating.

June 2019

Q. I intend to paint the exterior of my 1960s weatherboard house this coming summer. There are a number of old layers of paint on it so a lot of sanding and scraping is required particularly on the weathered side. I do not intend to take the weatherboards back to timber all the way around the house. I quite like the look of the dark colours (dark grey/black) on weatherboard houses. However I have been warned about using dark colours over old existing paintwork. Is this something Resene tends to agree with? Ideally I do not want to be painting my place again in five years' time. How do I stop the dark colour heating the old paint underneath and bubbling up?

A. Dark colours will increase the surface temperature and stress the existing paintwork, where there are many existing coats of paint application of a dark colours may cause an existing paint layer to fail. Application of a Resene CoolColour system will reduce but not eliminate the risk.

To be 100% sure strip if changing to a dark topcoat colour.

Painting over old coating always carries some risk as you never really know what state they are in. New acrylic coatings are more flexible than older coatings and can often create ‘surface tension' through the extra movement/flexibility which lifts the older coating in the form of bubbles. Darker colours transfer more heat into the older coatings and this can exacerbate this type of issue. In simple terms black is a risky colour choice.

We can't guarantee you won't have an issue however the use of Resene CoolColour™ technology reduces the amount of infrared heat transferred into the old coatings and substrate and therefore will reduce the heat related issues when compared to standard coatings.

My personal advice would be to choose a lighter colour and not select black or dark colour.

June 2019

Q. Last summer I got as far as undercoating an exterior door and would like to finish the job. It is under a covered porch without exposure to sun or rain. Will I have to sand it right back or can I get away with a light sand, wash and reapply the undercoat? I used Resene Quick Dry.

A. If the primer has not been exposed to weathering degrease paying particular attention to areas of hand contact, lightly sand, dust off then re-apply the Resene Quick Dry.  Then topcoat.

June 2019

Q. We are using Resene Write-on Wall Paint in our commercial fit-out. Can you please clarify if the whiteboard paint is matt and will function as a projector wall?

A. Resene Write-on Wall Paint is a clear gloss that is applied over a pigmented base colour. The base colour we recommend for projection onto is Resene Silver Sand and can then be overcoated with Resene Write-on Wall Paint then used for projection. There will be an increased reflection due to the Resene Write-on Wall Paint gloss but this should not eliminate the system from use as a projection system.

June 2019

Q. I am using path and patio non slip on concrete which is old but in good condition. I have been given conflicting advice as to the requirement for undercoat, could you please advise me on this?

A. If there are signs of mould or algae, treat with Resene Moss & Mould Killer diluted and used to label directions, then if you can waterblast.  Allow to dry out and then apply a saturation coat of Resene Sureseal before applying topcoats of Resene Non-Skid Deck & Path.

June 2019

Q. I have had my bedroom plastered and had GIB® Cove installed by a professional. I used Resene Sureseal then two coats of Resene SpaceCote. I have just noticed deep cracks appearing under the bottom of the GIB® Cove. I am not sure if this is a paint problem or something else. 

A. Can't see any reason to say that it is a problem with the paint but it may be due to overcoating of the Resene Sureseal before it had fully dried, or over-building of the Resene SpaceCote topcoats. When a waterborne paint is over-built, it can have surface but not through dry and after a time a phenomenon known as mud cracking can occur.

The other possibility is movement of the coving.

June 2019

Q. We've just painted the outside of our house with Resene paint.

We'd now like to touch up and remove paint from our aluminium window frames. We've tried turps and careful scraping but that has not worked. Can you please advise a product and technique that could help us?

A. Suggest you carefully wet the areas that you want to remove the paint from with Resene Graffiti Cleaner and then follow the directions for removal. Note the word carefully, is to warn against getting the Resene Graffiti Cleaner onto any other painted surface.

June 2019

Q. Is Resene Non-Skid Deck & Path appropriate for a bitumen driveway? How do I prep the surface? Will it ice over?

A. Ensure the bitumen is clean and free from lichen and bio growth then apply a coat of Resene Membrane Primer followed by two coats of Resene Non-Skid Deck & Path. If the paint profile gets full of water and then freezes, the slip resistance will not be present.

June 2019

Q. Is Resene Lustacryl semi-gloss enamel suitable for painting a door?

A. Yes, Resene Lustacryl as long as the door is correctly prepared and primed.

June 2019

Q. There is a wooden trim around my benchtop which gets quite a lot of traffic and water splashes and this is where the paint is scratching off. I want to go over it again with something hard wearing and a friend suggested oil based paint? I am wondering if you could give me some advice.

A. Sand back the existing paintwork to a sound base and apply a full coat of Resene Quick Dry, then finish with two coats of Resene Lusta-Glo enamel.

If water is getting in behind the paint system there may still be an ongoing adhesion issue.

June 2019

Q. I have just built a Hampton style home, with floor to ceiling tongue and groove walls in my mudroom. I am going to be painting them in Resene Black White but what finish options would you recommend? My skirting and architraves will be semi-gloss. 

A. We recommend Resene SpaceCote Low Sheen.

June 2019

Q. What type of finish should I use for a bookcase? I have plenty of matt finish paint that we used for the walls and I was going to use that for the wall bookcase or should I get matt enamel?

A. Standard waterborne wall paints do not have great wear resistance so may be damaged if used for painting a book case, however this is not to say they can't. We would usually recommend either Resene Lusta-Glo or Resene Lustacryl for this application.

June 2019

Q. Which paints in your range (if any) would be safe to use on a baby's cot? The cot is currently stained/varnished - unsure of the original product used. I think we would need to sand before repainting.

A. Thoroughly sand, dust off and then apply a coat of Resene Quick Dry primer undercoat and finish with two coats of Resene Lustacryl.

Leave the paint system to cure for at least two weeks then wipe down with warm water, rinsing the cloth often before placing into use.

Both products are Environmental Choice Approved and contain no heavy metals or formaldehyde.

June 2019

Q. We are looking for a clear sealer to be applied over an interior surface. The substrate includes both new plaster over existing brickwork and new concrete blockwork. The sealer topcoat should generate a ‘natural' finish to the new blockwork (doesn't look wet etc.).

A. Apply solventborne Resene Waterborne Aquapel to saturate the surface, leave to cure for at least 48 hours with good ventilation before topcoating.

June 2019

Q. I have undercoated an exterior rough sawn cladded area of my house and unfortunately the weather conditions changed quickly to be cooler and foggy (moist). The undercoat has not dried in certain areas. What can be done to remediate this problem? 

A. I would have expected the primer to dry off when drier conditions returned.

However given that the substrate is rough sawn, sanding of the affected areas will be difficult. Suggest you get a Scotch Brite pad for sanding, rub down the affected areas then re-prime.

June 2019

Q. I want to paint my existing kitchen. It is MDF with a spray paint finish. What low sheen paint would you recommend and how many coats? Incidentally I tried a drawer by just painting with waterborne paint a year ago and that is still ok, so no problem with adhesion.

A. We would normally recommend sanding to profile then application of a full coat of Resene Quick Dry primer undercoat before applying two coats of Resene SpaceCote Low Sheen Kitchen & Bathroom for a low sheen finish.

June 2019

Q. My house is 20 years old and the internal garage is still paperfaced and has been plastered. The plasterboard has turned a yellow brown colour so I am assuming that I would need to use Resene Sureseal to seal this? My only concern is that I have a newborn in the house and would prefer not to use a solventborne sealer, however I want a good finish. What would be the best way to go about completing this without getting the strong fumes in the house? I was thinking I could tape up the internal garage door to the house and paint with the garage door open?

Also if I do use Resene Sureseal, can I then use waterborne paint for a topcoat?

A. Yes, we do recommend using Resene Sureseal for old yellowed plasterboard as the sealer stops the bleed of the yellow into waterborne topcoats.

You could use Resene Boadwall Waterborne Wallboard Sealer for newly stopped plasterboard then apply a full coat of Resene StainLock before applying two coats of the interior waterborne topcoats. There may be colour bleed into the Resene StainLock but the colour will not subsequently bleed into the topcoats.

This will give you a waterborne low odour system. You can topcoat Resene Sureseal with our waterborne interior wall paints.

June 2019

Q. Can you recommend a low sheen hard wearing paint suitable for interior woodwork such as skirts, doors and windows?

A. Typically we specify semi-gloss or full gloss enamels on timber joinery as the higher the sheen level the better the abrasion resistance etc.

You can use Resene SpaceCote Low Sheen also as it also a waterbased enamel and suitable. Point to note though - lower sheen products can be more susceptible to burnish marks when darker colours are selected so this would be something to keep in mind. If you do choose darker colours consider applying Resene SpaceCote Clear over the top to protect against burnish marks.

June 2019

Q. My father has purchased a unit with a sliding door. There is a panel of yellow 70s glass, and I would like to paint over this with same wall colour. Is there an etch type primer that will allow acrylic paint to adhere?

A. Yes, for painting out glass you can use Resene Waterborne Smooth Surface Sealer as the adhesion primer. Leave to dry for 2-3 days prior to applying your topcoats so that it has a chance to key into the surface. You will need to paint both side of the glass.

June 2019

Q. I have nearly completed a garage conversion and have lined the walls with plywood. We want to keep this plywood look, what Resene products do we use? Is it polyurethane?

A. For a clear interior system we recommend three coats of Resene Aquaclear waterborne varnish.

June 2019

Q. I'm renovating the inside of our 1970s home which still has the original wallpaper in it. Some has been painted over and some has not. It is all proving to be very difficult to remove. What I was wondering is, is there any way of being able to paint over the wallpaper by maybe applying Resene Sureseal or something similar?

A. Re the removal difficulty, there is a PVA wallpaper adhesive that was in common use that makes paper removal almost impossible without damaging the underlying plasterboard.

You will need to apply a coat of Resene Vinyl Wallpaper Sealer before applying the waterborne wall paint system. Make sure the room is well ventilated during application. Do not try to clean out application equipment after completing the application, as this will require use of copious quantities of solventborne cleaner. Do not overwork the coating during application as due to the fast dry there will be a stage where the applied wet film is partially dry and may pull up.

June 2019

Q. Can you please advise how to wash walls so that they don't show marks from the damp cloth when they are dry?

A. The tide mark effect is due to the presence of surfactants on the surface, these are normally bound up in the dry paint film but under certain curing conditions, they can rise to the surface. Wipe down the whole wall using warm water and Resene Interior Paintwork Cleaner.

June 2019

Q. I would like to paint the outside of my antique claw foot bath. It's currently a dark racing green. I'd like to paint it to both lighten the room and to have it match the skirting – Resene Pearl Lusta. Do I need to use a special paint for the outside of the enamel bath or can I just use ordinary interior paint? It's a very professional, smooth, even finish which suggests factory. There's also no hint of the green paint anywhere around the bath which suggests it was painted elsewhere and then installed. It's painted over all the sides and underneath, so my guess is it is a factory enamel finish.

A. Sand to profile for recoating, apply a coat of Resene Enamel Undercoat and finish with two coats of Resene Super Gloss or Resene Lusta-Glo.

June 2019

Q. Our painter has dropped dark paint drops while painting wooden shingles onto Oamaru stone. I am seeking a solution to remove them please.

A. I suggest that you use Resene Graffiti Cleaner following label instructions.  Due to the porosity of the Oamaru stone you may have to repeat this (if so, allow the area to dry before re-applying the cleaner).

June 2019

Q. Can you provide information on how to halt ongoing weeping of gum from painted weatherboards?

A. This can be a difficult problem to completely control to achieve no future resin bleed.

Scrape back the area showing bleed to the bare timber, removing the gum exudate, then apply a coat of Resene Aluminium Wood Primer and allow to hard dry (note this may take many days to occur). Then reapply two coats of the topcoat colour. Dark colours will exacerbate resin bleed potential.

I have seen resin bleed when pine weatherboards were painted white, the above remedial system did achieve a degree of reduced bleed.

June 2019

Q. Can you paint over a polyurethane cork tile floor? What paint would you recommend for a whitewashed look?

A. Ensure the floor is clean and then sand (180 grit sandpaper) to profile for recoating. Then apply one or two coats of Resene Colorwood Whitewash. Care is required to avoid lapping (overlap), as there will be a more intense whiteness where overlapping occurs.

June 2019

Q. My daughter has just painted her bathroom and noticed she has spilt Resene Sureseal on the Resene Qristal ClearFloor 1K varnished floor. Can you tell me how to remove the Resene Sureseal without damaging the Resene Qristal ClearFloor? There are drips and spots in a number of places. We haven't done the final coats of Resene Qristal ClearFloor. The floor is stained with Resene Colorwood.

We have already had to take the floor right back and sand and redo all levels after an accident with plasterboard glue, so sanding and redoing can be done but it would help if you can suggest something to get the worst off. 

A. Carefully wet sand the Resene Sureseal spots/drips using 220 grit wet and dry paper to remove the Resene Sureseal, then re-apply the clear varnish.

June 2019

Q. Do you sell latex paint? If so, can I get testpots?

A. Latex is an old fashioned term for a waterborne paint; Resene sells a large range of waterborne paints including testpot colours.

June 2019

Q. I've been stripping back door frames and doors at my 1930s house then sanding, and wherever there is pine, I've been successfully staining it with Colorwood stain with no problems. I've just stripped and sanded the skirting boards and they are a very pale pine - different from the stuff I've done before. I can't get the stain to work on the skirting boards - there are white patches in the pine which won't take the stain, so it is uneven and blotchy. I'm not sure what to do and have become quite discouraged. Should I have just tried oil based or gel stain or is there no hope for these skirting boards?  It is quite blotchy pine to start with.

A. The whiteness may be undercoat residue which has not been removed.  I have seen this when stripping very old paint systems.

You may have to accept painting with a fully pigmented paint system to achieve an aesthetically acceptable finish.

June 2019

Q. I need to paint some window putty. The paint according to the putty container needs to be oil based. Can I use Resene Sureseal pigmented sealer as primer and then put on two waterborne topcoats?

A. Let the new putty develop a skin then use Resene Enamel Undercoat (not Resene Sureseal) as the priming system.  Then you can topcoat with the two waterborne topcoats.

June 2019

Q. We have a Lockwood home built in the 70s and the walls are definitely out of date. We would like to paint it using Resene products. The walls are covered with a polyurethane coating and we will sand this off lightly before applying a sealer/primer. We want to know what Resene primer/undercoat is best (preferably water based) and we do not want any bleed through. We would like your professional opinion as to water based undercoat compatibility with old Lockwood as opposed to oil based.

A. Ensure the existing polyurethane is grease free and lightly sanded then apply an adhesion coat of Resene Waterborne Smooth Surface Sealer. Apply a thin coat of Resene Waterborne Smooth Surface Sealer and allow to cure without water contact for at least 48 hours before overcoating. The sealer is not designed to be applied as a thick wet film thickness or give opacity, the thinner the coat the better. Then apply two coats of Resene SpaceCote Low Sheen. The new paint system will take five days to develop good initial adhesion and continue to cure for an additional three weeks until full cure occurs. In the early stages, the paint surface will not have good resistance to cleaners or abrasion as these features develop as the film undergoes curing.

Note: The walls of Lockwood can expand and contract, if the wall sections shrink this can expose a line of the original varnish system where boards overlap. 

June 2019

Q. We want to repaint a light metal garage door. What paint should we use, there are some parts back to the metal, and otherwise it is mostly covered by existing paint?

A. If any areas of moss or mould infestation exist then treat them with Resene Moss & Mould Killer diluted and used to label directions. For heavy infestations more applications may be needed.

Scrub down using Resene Paint Prep and Housewash diluted and used to label directions. Rinse clean or hose down with fresh water ensuring all salts are also removed.

All paint that is flaking or unsound must be removed by using mechanical methods, (3M Rust and Paint Removal Disc), chemical stripper or high pressure waterblasting taking care not to damage either the substrate or the surrounding areas.

Remove all areas of white corrosion material and as much red rust as is practicable and all paint that is flaking or unsound must be removed by using mechanical methods e.g. 3M Rust and Paint Removal Disc, taking care not to damage either the substrate or the surrounding areas.

Where under-film corrosion is taking place the existing paint must first be removed as above and remove under film corrosion products taking care not to damage sound zinc coated areas. All paint edges must be feathered to a smooth finish.

Note: The performance of the subsequent paint systems will be largely dependent on the thoroughness of this surface preparation stage.

Ensure all edges of damaged paint are sound and immediately spot prime all areas of corrosion and bare metal with Resene GP Metal Primer then finish with two coats of Resene Summit Roof.

June 2019

Q. I am painting the bathrooms at my school. The surface is aluminium and I already have the etch primer (oil based). I am planning to paint things on top of this layer, and want to use testpots. I understand that you can only paint oil based on top of oil based, and was wondering if the testpots are oil based?

A. Resene testpots are waterborne and they can be used as the topcoat paint for aluminium primed with an etch primer. 

June 2019

Q. I'm looking to repaint the bedrooms in our house, repainting them white again. I did the entire exterior and have a lot of left over undercoat. Is it ok to use this on the interior?

A. Resene Quick Dry can be used as a primer/undercoat for both exterior and interior applications.

June 2019

Q. I have prepped my room completely and undercoated the whole thing with Resene Quick Dry. I have bought Resene Ceiling Paint and Resene SpaceCote Low Sheen for the walls but have not started putting it on.

Can you please advise if it's okay to paint the scotia on the room using the Resene Ceiling Paint and also the skirting boards using the Resene SpaceCote Low Sheen?

A. Resene Ceiling Paint can be used for the scotia, the higher the gloss level of the skirting paint the better wear.  We would normally suggest Resene Lustacryl as the topcoat for skirting.

June 2019

Q. What is the ideal temperature to paint walls and ceilings inside?

A. Around 18⁰C with humidity in the mid 60s.

June 2019

Q. We have specified Resene Aquapoxy to be painted on an internal concrete wall for a new laboratory fit-out project. Can you please check and advise if the Resene Aquapoxy paint will be compatible with the proposed foam and sanitiser systems?

A. A full cured Resene Aquapoxy system will be resistant to sanitising using Foam Klenz, but will discolour when exposed to TOPACTIVE DES as the latter contains strong oxidants.

We assume that the sanitisers are washed off the coated surfaces are part of the process.

Overcoating of the Resene Aquapoxy with a waterborne two pack pigmented polyurethane topcoat such as Resene Uracryl 803 will allow for cleaning with the TOPACTIVE DES sanitiser.

June 2019

Q. What product would I use on outdoor New Guinean Rosewood timber furniture?

A. New Guinean Rosewood bleeds plenty of tannin, so either  allow to weather or wash with Resene Timber and Deck Wash diluted and used to label directions then apply a coat of Resene Aluminium Wood Primer and then you can finish with an exterior Resene waterborne paint system such as Resene Quick Dry and two coats of Resene Lustacryl.

Resene Aluminium Wood Primer is slow to reach hard dry, so do not overcoat until the primer has achieved hard dry. Hard dry can be tested by placing the thumb on the coating and twisting through 90 degrees, if there is no thumbprint or damage then hard dry has been achieved.

June 2019

Q. What is the best way to deal with surface rust on galvanised nails, on a COLORSTEEL® roof (20 years old), prior to painting in a seaside location?

A. Wash down using Resene Roof and Metal Wash diluted and used to label instructions. Remove all areas of white corrosion material and as much red rust as is practicable. All paint that is flaking or unsound must be removed by using mechanical methods e.g. 3M Rust and Paint Removal Disc, taking care not to damage either the substrate or the surrounding areas.

Prime the prepared rusted nails with two coats of Resene GP Metal Primer and then topcoat with Resene Summit Roof.

June 2019

Q. Is there a Resene paint that could be applied to Clearlite® plastic sheeting? The existing fence features clear corrugated plastic rather than timber or iron.

A. A Resene exterior waterborne paint can be used, such as two coats of Resene Lumbersider.

June 2019

Q. I have some Resene Membrane Primer. It was opened in early 2018. I can't fully remember its smell back then, but it now smells pungent. It has a typical PVA smell with hints of acetic or butyric acid.

There is no reason it should've been contaminated. Is this normal the normal smell?

A. If the product was used for priming butynol or the like and material poured back into the can, then this will give the odour you report. The product extracts a sulphur material from the butynol.

June 2019

Q. I want to stain my access stairs with a product like Resene Kwila Timber Stain. However I would like to add a gritted texture to the stain to ensure that I comply with D1 of the building code, but I don't want to put adhesive tapes on the treads. Is there a product you would recommend to add?

A. We cannot produce an exterior stain with slip resistance, Resene stains are designed to erode upon weathering and as a consequence an aggregate used to give slip resistance cannot be held within the stain coating.

June 2019

Q. Can you tell me if downpipes should be removed, if roof water is supplying a water tank, prior to using Resene Moss & Mould Killer?

A. If the active in the Resene Moss & Mould Killer completely reacts then the reaction product is sodium chloride, common salt. However, in practice this does not always occur so to be safe, disconnect down pipes for all stages of preparation and painting, allowing the rain shower washing after completion of painting before reconnection.

June 2019

Q. I have 100 Merinta Plywood sheets which need to be sealed prior to installing on site. On the face of these sheets I will be gluing some pressed steel lightweight panels. Can you recommend a suitable sealer from your range or can we use the Resene Waterborne Smooth Surface Sealer as a suitable product for this application?

A. This timber is very prone to irreversible fibre swell if waterborne sealer is used. Suggest you try a coat of Resene Qristal Clear Poly-Gloss.

June 2019

Q. We have new H3 construction ply on the floor and are looking to paint it. Can you please tell me the process? We are looking to avoid sealing with polyurethane. The floor will have very light foot traffic without shoe traffic. 

A. We recommend a seal coat of Resene Quick Dry and two coats of Resene Lustacryl.

The system will not give wet slip resistance. There may be a degree of irreversible fibre swelling depending upon the grade of ply used.

June 2019

Q. I am currently trying out a Resene wood stain on the exterior of our house which is a solventborne one. When we next stain in a couple of seasons, are we able to stain over the top with the Resene waterborne stain?

A. Yes, as long as the existing stain has undergone weathering for at least 12 months.

June 2019

Q. The previous owner of our house installed a butynol waterproof membrane on the balcony, and it's coated with some sort of paint. Would you know what kind of paint this is? Should we repaint over it every few years? If so which product would you recommend?

A. Waterborne paints are applied to butynol to protect the butynol from breakdown due to weathering. The paint does not add to, or diminish the features of the butynol.

If the paint system is sound, it should not need recoating.  If it does need repainting, we usually recommend Resene Lumbersider.

June 2019

Q. We built our house 13 years ago and it has a Resene Ironsand roof. We first painted our barge boards. Unfortunately this failed and split in the first few years so we started over. Cleaned, prepped and redid it with another product but that only lasted a year as well. Start over again, and did it in another product to no avail. It happened again.

Recently I approached a roofing company to see if he could redo the barge boards in COLORSTEEL®. He said he had had the same issue with his house and he redid his in Resene CoolColour and that worked!

So my question is, given we haven't touched the barge boards for a number of years. What should be my next steps in terms of preparation, gap filling, priming/undercoating before repainting in Resene CoolColour paint?

A. A Resene CoolColour™ topcoat will not render the painted surface cool to touch but the CoolColour version will reflect more heat than the same colour made on non-cool technology.

Dark colours may cause the rapid drying of damp timber with the ensuing danger of warping, though this effect will be lessened when a CoolColour is selected in place of a standard colour. I recommend a total strip back to bare timber, thorough sand and then apply two coats of Resene Quick Dry and finish with two coats of Resene Sonyx 101 CoolColour Ironsand.

This system will give the best chance of achieving a better long term option than your previous systems.

June 2019

Q. We have painted ‘Resene Lumbersider low sheen paint on our Hardiplank® house and it looks very shiny. What can we do to flatten the look?

A. Resene Lumbersider is our lowest gloss level exterior finish for standard waterborne paints. I am surprised to hear that it is shiny as this is not the norm.

Curing conditions can lead to exudation of the wetting agents in the paint to the surface and this can appear shiny. Suggest that as a first step, you scrub down using Resene Paint Prep and Housewash diluted and used to label directions.

June 2019

Q. I am looking for some technical advice regarding the selection of a coating product for exposed reinforcing bars in a concrete panel. We are proposing to cut a hole in an existing precast concrete wall panel which will leave the ends of some reinforcing bars exposed on the cut edge of the opening. Do you have an appropriate coating system in your range that we can locally apply to the exposed ends of the reinforcing bars to protect them? The exposure category is B1 so it is not in an aggressive environment. I was hoping that something along the lines of an epoxy coating would do the job.

A. We recommend 2-3 coats of Resene Armourcote 221 epoxy primer. The rebar steel will need to be roughened using Emery paper to profile for coating adhesion.

June 2019

Q. Can you let me know what paint you would recommend for repainting an existing metal workshop and roof please. Should I use Resene Lumbersider or something else? 

It is a COLORSTEEL® workshop.  The overall paint condition is excellent, no evidence of rust etc. I am painting the house so need to change the workshop colour. 

A. Depending upon the degree of weathering, it can be tricky to get adhesion to COLORSTEEL®, so for best results apply a full coat of Resene Pre-Coated Steel Primer then two coats of a waterborne topcoat. We usually recommend Resene Summit Roof. Resene Lumbersider can be used but for a roof it is not as durable as Resene Summit RoofResene Lumbersider works well for vertical claddings.

June 2019

Q. Do you have you some tips for repainting skirting that sits along/against carpet? Looking for ways to pull carpet away/hold back etc. without removing the carpet.

A. Use a wallpaper ezy trim edge as a straight edge, place edge against the skirting then push back to expose the edge to be painted. After completion of a section, wipe the edge to remove wet paint before repositioning.

Alternatively, use a strong masking tape to cover the carpet, smooth out to get close to the skirting line.

June 2019

Q. I am looking for the right product to treat my rimu floor in the bathroom. I understand it has to comply with the NZS 3602, H3.1 level as a minimum (I am applying for building consent, and want to do the job myself). I want to demonstrate that the product I am going to use is compliant. Which product from Resene would do the job?

A. We recommend Resene Polythane, 3-4 coats.

June 2019

Q. I would like to know if it is possible to paint existing creamy/beige kitchen floor tiles and medium dark brown bathroom floor tiles without having to remove and replace them. What product would change the floor colours?

A. Yes, you can paint out tiles but you will need to keep in mind that the paint finish will be susceptible to damage over time so may require maintenance.

Assuming they are glazed type tiles: ensure the tiles are clean and free of grease/oil residues then apply one coat of Resene Waterborne Smooth Surface Sealer (this only needs to be a thin coat and will not achieve opacity over the laminate colour). Allow to cure for a minimum of 48 hours.  Then apply two coats of Resene Walk-on and one coat of Resene Concrete Wax.

The paint system will take at least five days to develop adhesion and harden, full cure requires a month. The painted surface will not have the hardness properties of the original tiled surface.

June 2019

Q. I bought paint to start painting my whole house from inside. I'm being told by others not to do it in winter. Can I turn the heaters or dehumidifier on and paint or not?

A. There are recommended application conditions for application of waterborne paints. During winter, the interior temperature and humidity requirements for application of waterborne paint are often outside of the required application conditions. To achieve the required environment conditions, a combination of heating and removal of water from the room atmosphere (dehumidifying) will allow application of waterborne paint to be undertaken.

Suggest that prior to paint application, that the interior room temperature is brought up to around 15 degrees Celsius, then when application of a coat of paint is completed switch on the dehumidifier while maintaining room heating. Note that heating must be with a heater that does not produce water vapour. Electric heaters will not produce water vapour and are safe to use for achieving drying of waterborne paint.

June 2019

Q. I am doing up a caravan and have pulled back one leaking part to reveal bare metal. Just wondering if there is any particular paint I can use to weatherproof temporarily and prevent rust until I am ready to fully paint the outside. 

A. Wire brush to remove loose rust then apply two coats of Resene GP Metal Primer.

June 2019

Q. We have purchased a house with hardboard walls and ceiling in the kitchen, which has been painted with gloss paint. We have purchased Resene Waterborne Smooth Surface Sealer to use on varnished window frames and are wondering if this can be used on the painted hardboard. 

A. As long as the gloss paint is traditional enamel paint then in principle you could use Resene Waterborne Smooth Surface Sealer as the adhesion primer, ensure the hardboard areas to be painted are degreased before applying the sealer.

Apply a thin coat of Resene Waterborne Smooth Surface Sealer and allow to cure without water contact for at least 48 hours before over coating. The sealer is not designed to be applied as a thick wet film thickness or give opacity, the thinner the coat the better. Then apply two coats of Resene SpaceCote Low Sheen Kitchen & Bathroom. The new paint system will take five days to develop good initial adhesion and continue to cure for an additional three weeks until full cure occurs. In the early stages, the paint surface will not have good resistance to cleaners or abrasion as these features develop as the film undergoes curing.

Alternatively, degrease and sand to profile then apply a coat of Resene Quick Dry before applying two coats of Resene SpaceCote Low Sheen Kitchen & Bathroom.

June 2019

Q. I'm wondering what product to use to paint the block wall inside my garage a non-shiny black and the steps to take to paint it. I would also like to know which product to use to paint the rest of the garage wall a shade of white?

There doesn't appear to be paint on the block wall, the wall is weathertight, just the usual openings in and around the garage door that prevent the garage from being 100% weathertight however, these openings are minimal. 

A. Apply a primer coat of Resene Concrete Primer and finish with two coats of Resene Lumbersider.

June 2019

Q. I'm staining a kwila deck with the Resene Kwila Timber Stain and wanting to match an adjoining pine timber path in colour. If I can use the Resene Kwila Timber Stain on both then that's cool, but if I can't then I'll go with the Resene Woodsman Cedar on the pine.

A. Suggest the better product for this application Resene Woodsman Wood Oil Stain tinted to a Kwila colour. Resene Kwila Timber Stain is designed to achieve a kwila look to rejuvenate the kwila colour.  As pine is a very light timber the Resene Kwila Timber Stain will look quite different to how it does on the kwila.

June 2019

Q. I am considering installing a 'built-in' gas fireplace in our living room. It would be put into a plasterboard wall that has been painted with Resene paint but I can't remember which product.

The installation manual for the fireplace quotes "NOTE: The wall lining directly above the appliance will get warm and hence may discolour paint finishes that are susceptible to temperature damage or distort vinyl wall coverings. For durability of finishes and surfaces you should contact the relevant manufacturer for their specification and avoid materials with temperature ratings less than 80deg C."

I would be happy to repaint the wall with an appropriate product that can withstand those sorts of temperatures. Do you have a suitable product?

A. A solventborne enamel system will achieve the heat resistance but pale colours will yellow over time.

Apply a seal coat of Resene Sureseal to the bare plasterboard then apply two coats of Resene Lusta-Glo.

June 2019

Q. We are looking at getting a new entrance door and the two options we were looking at (even though solid) have stated on them not to be painted a dark colour. What would be considered a dark colour and would it be ok to use Resene CoolColour dark paint or not?   Is this something specific to the doors we were looking at or all doors – i.e. would we be better to just paint the existing one the dark colour we wanted?

A.  I would use an LRV colour cut-off of 40% or less as being a dark colour. If selecting a topcoat colour with an LRV of less than 40% we would recommend the Resene CoolColour™ system, a coat of white primer and two coats of topcoat tinted to the CoolColour tint formulation.

The CoolColour top coat will not render the painted surface cool to touch but the CoolColour version will reflect more heat than the same colour made on non-cool technology. Dark colours may cause the rapid drying of damp timber with the ensuing danger of warping, though this effect will be lessened when a CoolColour is selected in place of a standard colour.

It is a key requirement to envelope prime top/bottom and side edges of the door with a solventborne wood primer to seal against water uptake.

June 2019

Q. What products do you recommended on a small bathroom? It has new plasterboard and stoppings.

A. Assuming that the lining is GIB® Aqualine, then apply a seal coat of Resene Sureseal and undercoat of Resene Quick Dry and finish with two coats of Resene SpaceCote Low Sheen Kitchen & Bathroom or Resene Lustacryl Kitchen & Bathroom.

You will need to leave the paint system to cure for at least three days after application without water/steam contact of the last coat of top coat, also ensure the room is well ventilated and warm while the paint is drying.

June 2019

Q. I've had painters in and they have been using a white Resene semi-gloss waterborne paint.  They had one hard-to-reach spot which they have done today - two coats within 1.5 hours.  I questioned how this was possible given a recoat time of two hours and they insisted the paint was dry as it was warm in the skylight well.  They said the paint looks fine.  I questioned whether there was another reason for the repaint time such as durability. 

A. The recoat time is a function of temperature, humidity and air flow.

The data sheet/label recoat times are usually at 18 degrees Celsius, and at higher temperatures, lower humidity and good air flow, the paint can dry faster and be recoated quicker.

If this is an internal application I see no real issue re durability.

June 2019

Q. Generally, when will I have to reapply paint in a regular maintenance schedule and reapplication with no maintenance.

A. Typically a recoat to maintain aesthetics for a semi-gloss or gloss finish on a vertical surface would be required around year 8 onwards. There should be no peeling or flaking but loss of gloss and possibly colour fade. Northern elevations which receive the most intense weathering may require earlier attention.

June 2019

Q. If painting a new COLORSTEEL® roof using Resene Summit Roof paint, do you need to prime it first?

A. Yes, prepare and apply Resene Pre-Coated Steel Primer then the Resene Summit Roof paint.

June 2019

Q. I am looking for a safety paint that I can use on a wooden deck to make it less slippery when wet.

A. We recommend Resene Non-Skid Deck & Path.

June 2019

Q. I want to repaint my garage, which is I think galvanised steel. It has some red rust under the flaking paint. Can you advise the best way to do this?

A. If any areas of moss or mould infestation exist, then treat them with Resene Moss & Mould Killer diluted and used to label directions. For heavy infestations, more applications may be needed.

Scrub down using Resene Paint Prep and Housewash diluted and used to label directions. Rinse clean or hose down with fresh water ensuring all salts are also removed.

All paint that is flaking or unsound must be removed by using mechanical methods, (3M Rust and Paint Removal Disc), chemical stripper or high pressure water-blasting taking care not to damage either the substrate or the surrounding areas.

Remove all areas of white corrosion material and as much red rust as is practicable and all paint that is flaking or unsound must be removed by using mechanical methods e.g. 3M Rust and Paint Removal Disc, taking care not to damage either the substrate or the surrounding areas.

Where under-film corrosion is taking place, the existing paint must first be removed as above and remove under film corrosion products taking care not to damage sound zinc coated areas. All paint edges must be feathered to a smooth finish.

Note:  The performance of the subsequent paint systems will be largely dependent on the thoroughness of this surface preparation stage.

Ensure all edges of damaged paint are sound and immediately spot prime all areas of corrosion and any other bare metal with a full coat of the specified primer.

Spot prime prepared areas of corrosion and bare metal with two coats of Resene GP Metal Primer then apply two coats of Resene Summit Roof.

June 2019

Q. We have 27 outdoor bench seats to paint. Some that have been under cover from the elements have sound varnished wooden seat tops and back rests.

Others are plain sound wood that has had any original coating worn off completely over the years by the elements, while others have a bit of paint and a bit of bare wood! Any residual paint is sound and oil based (after using the meths test).

They all sit on steel frames that we will paint as well, and they have sound paint and again no reaction to meths.

So the questions are: what paint system would be most suitable for this application, both steel frames and the wood? Preferably not full gloss paint. And is there a single primer/sealer that can be used over both the existing paint and the bare wood?

A. Degrease using Resene Paint Prep and Housewash diluted and used to label directions.

Sand the varnished benches to de-gloss and sand the exposed benches to remove all loose and flaking areas back to a sound edge and to profile remaining sound coatings.

Then apply a full coat of Resene Quick Dry and finish with two coats of Resene Lustacryl.

Assuming no corrosion of the steel supporting structure, then the same prep as above and you can use the same system. Note if there are any bare steel areas or areas of corrosion, these will need to be prepared back to a sound base and bare steel primed with Resene GP Metal Primer before applying the above paint system.

June 2019

Q. I am restoring wooden toys for children. What varnish can I use to protect the paint please? It also needs to be non-toxic.

A. Suggest you use Resene Aquaclear.

June 2019

Q. What paint can you suggest to paint over a residential concrete garage floor?

A. We recommend Resene Aquapoxy for Flooring.

June 2019

Q. I'm painting my interior new plasterboard ceiling, walls and joinery. I have done one coat of Resene Sureseal over the finished plasterboard. It is quite thin and the stopping can be seen clearly underneath.

I think maybe I should now do a coat of Resene Quick Dry before I do the two topcoats.

Is using Resene Quick Dry next, on top of Resene Sureseal and before the two topcoats a good idea, or would you suggest something else? I assume I can put any topcoat over Resene Quick Dry?

A. Resene Sureseal is not designed to achieve 100% hiding over stopped plasterboard. I always recommend applying an undercoat of Resene Quick Dry over Resene Sureseal for wet areas before applying a waterborne enamel topcoat system.

We normally recommend using Resene Boadwall Waterborne Wallboard Sealer for sealing stopped plasterboard in non-wet areas but Resene Sureseal can be used with Resene Quick Dry as an undercoat. You don't need Resene Quick Dry if Resene Boadwall Waterborne Wallboard Sealer has been used to seal the plasterboard and stoppings.

June 2019

Q. How can I prevent recently painted timber windows from sticking? I have previously found that they tend to stick to the frames when closed, even after the paint has been on for a few days. 

A. The issue you have, seems to fit with no or poor block resistance,  

Block resistance is the capability of paint, when applied to two surfaces, not to stick to itself upon contact when pressure is applied. For example, good block resistance helps keep a door from sticking to the jamb or a window from sticking to its frame. Standard waterborne paints have poor block resistance.

Resene Enamacryl is based on a cross linking waterborne resin and when cured does have block resistance. I suggest that you coat the contact areas that have not been painted with Resene Enamacryl, with a coat of Resene Quick Dry and then apply two coats of Resene Enamacryl. Leave the new paint to dry for a full day before closing.

June 2019

Q. Is it possible to paint a melamine wardrobe? I am hoping to restore an old one for my daughter, so do you think it's possible to sand it back and apply primer and then waterbased or acrylic paint?

A. Using Resene Interior Paintwork Cleaner ensure the surfaces to be painted are clean and free from grease, and pay particular attention to hand contact areas.

Apply a thin coat of Resene Waterborne Smooth Surface Sealer and allow to cure without water contact for at least 48 hours before over coating. The sealer is not designed to be applied as a thick wet film thickness or give opacity, the thinner the coat the better. Then apply two coats of Resene SpaceCote Low Sheen or Resene Lustacryl.

The new paint system will take five days to develop good initial adhesion and continue to cure for an additional three weeks until full cure occurs. In the early stages, the paint surface will not have good resistance to cleaners or abrasion as these features develop as the film undergoes curing.

Note that painting will not reproduce the original features of the laminate.

June 2019

Q. I have a new gate with silver metal hinges, probably galvanised steel and I want to paint them black. What paint should I use?

A. Prime the bare galvanising with Resene Galvo One primer then you can apply any Resene exterior waterborne topcoat paint.

June 2019

Q. I would like to paint over a Resene metallic painted feature wall with a new regular colour.  What priming process should I follow before applying the new Resene colour?

A. Apply a base coat of Resene Quick Dry then you can topcoat with any Resene interior wall paint.

June 2019

Q. Do you have advice on the best way to get paint out of clothes and carpets? We used waterbased enamel paint.

A. Suggest you try Resene Graffiti Cleaner as the paint is probably well dried. Check that the cleaner does not affect the material on either before using.

June 2019

Q. We are currently painting our garage and have discovered that the gutters are made of aluminium. They have been painted previously but through wash and wear, bare patches of metal are now visible. Is Resene Sonyx 101 suitable for application onto this, and if so what kind of priming would be required? 

A. Spot prime the bare aluminium with Resene Galvo One before topcoating with your chosen Resene exterior topcoat.

June 2019

Q. I have a house with board and batten exterior. It has been stained with Resene Woodsman oil based. It is in good condition and was applied 2 years ago. Can I repaint in acrylic paint? If so, what would the undercoat need to be?

A. Scrub down using Resene Paint Prep and Housewash diluted and used to label directions.

Apply a full coat of Resene Wood Primer and finish with two coats of Resene Sonyx 101 or Resene Lumbersider. Use the Resene CoolColour™ version of the topcoat colour if available. The CoolColour topcoat will not render the painted surface cool to touch but the CoolColour version will reflect more heat than the same colour made on non-cool technology.

June 2019

Q. I have a timber deck that I oil with Resene Timber and Decking oil. I normally just scrub it well before applying oil, but this year some of the timber is quite dark which I thought was due to the exposure to the weather. I've just oiled it, and have been told that maybe it is mildew making it dark, almost black in some spots.

Should I use something to remove the oil and mildew and then re-oil it or leave it until next time it needs oiling, and use some sort of cleaner beforehand?

A. The dark patches are more than likely mould growth and may be present under the oil film layer.

You could treat the deck with Resene Deep Clean diluted and used to label instructions and wait to see if this does result in any colour change, this will require weathering and may take at least four weeks before any change is seen.

If there is no change, you will need to wait till the next application and sand the surface then treat with Resene Moss & Mould Killer to kill the mould before re-oiling.

June 2019

Q. I want to paint a garage floor that is heavily stained with old oil. What is the best thing to use to remove the old oil?

A. Removal of the oil staining is critical to achieving a successful painting outcome. Suggest you try cleaning down using Resene Heavy Duty Paint Prep and Oil Remover diluted and used to label instructions.

June 2019

Q. I'm looking for a paint to go on a tiled floor area (about 1m x 1.5m area). It's the side internal entry of our house, and they're not glazed. Can you recommend anything?

A. Assuming the tiles are clean then apply a coat of Resene Sureseal and follow with two coats of Resene Walk-on.

June 2019

Q. I am wondering if there was something I can use/do to an item of clothing that has got some dry Resene testpot paint on it?

A. Suggest you try sponging the area with Resene Graffiti Cleaner, rub the cleaner into the paint spots (wear rubber gloves) to soften the paint then wash.  Test the cleaner on an inconspicuous area of the clothing first to ensure it does not affect it.

June 2019

Q. My family and I are building a house and I am looking for a sustainable paint solution. Can you please tell me how your paints measure in sustainability and whether or not your paints are red-list free? I would also like to know where they are made and if they have any animal ingredients in them?

A. Resene decorative waterborne paints contain no chemicals on the Red List and have no components derived from animals. Resene paints are formulated to meet the challenges of the local environment and manufactured in New Zealand at Resene owned manufacturing sites. We also use recycled plastic pails made from returned plastic packaging.

June 2019

Q. I am part of a community group that wants to upgrade a tired public space that has many 1960s brick planter boxes that double as seats. The idea is to paint the brick planter boxes in a variety of bright, funky and vibrant colours to lift the area. We plan to waterblast and clean up before painting. There is no obvious efflorescence. What paint system would give us the best longevity on the brick given that they will be sat and walked on?

A. Our standard system for painting would be to apply a coat of Resene Concrete Primer thinned 10% with water then two coats of any Resene exterior waterborne paint tinted to your required colour. Suggest Resene Lumbersider.

The lack of obvious efflorescence suggests that the interior face has been made water proof.

June 2019

Q. Could you please tell me what products you have that are suitable for priming and sealing wooden frames and architraves in a bathroom and washhouse and also topcoats?

A. Resene Wood Primer would be the primer for solid timber in a wet area such as a bathroom, there are two overcoat options - the first is for a traditional solventborne enamel – use Resene Enamel Undercoat and two coats of Resene Lusta-Glo, or a waterborne system using a coat of Resene Quick Dry and two coats of Resene Lustacryl.

June 2019

Q. Is Resene Lustacryl the best product to be used on pressed metal, to be used in my new kitchen, from bench to ceiling? The paint will need to be sprayed on. I do not want a high gloss finish, and definitely not matt, as the pressed metal has texture, and the cupboards will have a satin finish. What is the best choice to use, as I have also been told to use Resene SpaceCote Low Sheen Kitchen & Bathroom?

A. After a through degreasing apply a prime coat of Resene Galvo-Prime and then finish with Resene SpaceCote Low Sheen Kitchen & Bathroom (both paints to be spray applied). Resene SpaceCote Low Sheen Kitchen & Bathroom should give you your desired gloss level.

June 2019

Q. What sort of paint should I use on COLORSTEEL®?  It is 15 years old and very good condition.

A. Wash down using Resene Roof and Metal Wash diluted and used to label directions. Apply a full coat of Resene Galvo One and the two coats of Resene Summit Roof paint.

June 2019

Q. I need to repaint my very sunny kitchen bay window as the paint is peeling in parts. The surface is solid wood. What steps do I need to take i.e. sanding: do I need to sand all the area, primer, coats of paint etc. which paint would you suggest? It gets a lot of water condensation.

A. Sand back to bare timber and apply a coat of Resene Wood Primer and finish with a coat of Resene Enamel Undercoat and two coats of Resene Lusta-Glo tinted to your required colour. An all solventborne system will give the best resistance to the condensation.

June 2019

Q. I have a Vitex timber deck, overlaying a butynol covered base. I would like to paint or stain the deck but do not want to damage the butynol. The decking is ‘floating' on timber beams which sit on the butynol deck below.

A. I see no reason why a waterborne stain or paint system cannot be used for the timber; butynol will not be affected by a waterborne stain/paint.

June 2019

Q. Can I use Resene Quick Dry as a primer straight onto wood and if so, are there any types of wood that it's not suitable for use on? We have some wooden panelling in one room which we wanted to paint over, I'm not sure what type of wood it is but could possibly be rimu.

A. Resene Quick Dry can be used to directly prime bare timber, with the exception of tannin containing timbers such as cedar.

June 2019

Q. We were due to have the exterior of our house painted at the end of January but the painters have delayed twice and now plan to start this week, weather permitting. It is now April and I am wondering if it is too late to paint the exterior. Could you please give me some advice on when the painting 'season' is?

A. Resene has paints that allow painting almost all year round, so the convention of a paint season really is a thing of the past.

June 2019

Q. We are in the process of creating a large, open plan living area that combines the kitchen, dining and living room areas. The kitchen will be down one end. Will it be best to use kitchen paint for the whole room (walls and ceiling)? The sink will be on an island, not near any painted surfaces, and the cooking area will have a splashback.

A. You may as well use the Kitchen & Bathroom paint through the whole area.

June 2019

Q. What are the differences/advantages/disadvantages between U and Z CoolColour tints?

A. Z tinter is used to achieve a jet black colour, the tinter is infra-red transparent and a solid white base colour is what gives the infra-red reflectance to achieve the CoolColour.

U tinter is infra-red reflecting and in combination with a white base colour will give the maximum infra-red reflectance. A CoolColour made using the U tinter will have infra-red reflectance.

June 2019

Q. I am painting an old totara doorstep, which I have sanded. I have Resene Sureseal and your white primer. The topcoat will be oil based black. Which primer should I use?

A. Oil based primers such as Resene Sureseal will not dry when used to prime totara.

You will need to use Resene Quick Dry as the primer. Resene Quick Dry can be overcoated with an oil based topcoat such as Resene Super Gloss.

June 2019

Q. I would like to paint my house. I have a concrete tile roof (stripped bare) and fibrolite weatherboards that are currently painted.
What paint products do you recommend for my roof, do I need to seal the tiles prior to topcoat?
I have cleaned it and it's pretty clean but raw concrete, almost all original paint is gone.

A. Step 1: Rake out all joints and tile over laps to remove accumulated debris. Remove large clumps of moss using a scraper.

Step 2: Spot treat areas of heavy lichen infestation with Resene Moss & Mould Killer diluted 1:1 with water and leave for 48 hours before proceeding to Step 3.

Step 3: Treat areas of moss/lichen infestation a few weeks prior to the commencement of painting with a saturation coat of Resene Deep Clean diluted and used to label instructions. Resene Deep Clean is a slow release bio kill agent. Resene Deep Clean is best applied under overcast conditions to maximise wetting time.

Step 4: Waterblast at the maximum pressure that will not damage tiles to remove all dirt, grease, moss and mould residue, dust, and other contaminants. Care is needed not to waterblast under the tiles. Allow the surface to dry thoroughly. Resene recommend that downpipes are disconnected during this process and that gutters are thoroughly cleaned out before reconnecting downpipes.

Apply a saturation coat of Resene Sureseal and then two coats of Resene Summit Roof.

Q. Can Roof Summit be used on iron roofs as well?

A. Yes, as long as any bare metal areas are primed with Resene Galvo One.

June 2019

Q. I have a piece of old furniture I want to paint, and I have a testpot of the colour I want to use. Just wondering if an all-over coat of the testpot of Resene Lumbersider is sufficient to use as a primer/undercoat, or would I still need to buy something like the Waterborne Smooth Surface Sealer before applying Resene Lustacryl? It is old mahogany, not much varnish still on it, and clear coated. And I don't know if polishes have ever been used.

A.. Clean down using Resene Interior Paintwork Cleaner then sand to profile for recoating, you don't need to sand all the varnish back to bare timber. Dust off and apply a coat of Resene Quick Dry primer undercoat and finish with two coats of Resene Lustacryl.

Resene Waterborne Smooth Surface Sealer would only be used if there was a good thickness of existing clear varnish.

June 2019

Q. I have a metal garage door - unknown metal-type as it has been there for 10-20 years, previously painted yellow with unknown paint. It had mild rust, which so far I have sanded back and then spot-primed with Resene GP Metal Primer. We are 300 metres from the sea. Before any further topcoat, should I do any further priming across the rest of the door (although the old existing yellow paint is semi-ok)?  What paint system(s) would you recommend for the topcoats?

A. Ensure the surface is washed down with Resene Roof and Metal Wash diluted and used to label directions. Prepare corroded areas back to a sound base then spot prime these areas with Resene GP Metal Primer. Given your location, then apply a full coat of Resene Galvo One before topcoating with Resene Sonyx 101 or Resene Hi-Glo. The role of the topcoats is to protect the priming system from weathering and for colour. Resene Hi-Glo will have a longer time until the onset of surface chalking.

A regular wash down with fresh water of the door will assist in achieving a better long term outcome re corrosion, as this will wash salts that accumulate on the painted surface.

June 2019

Q. I want to know what paint to use on a drawer set I would like to paint. The set of drawers are old varnished wood. I'm not sure what to use for the topcoat. Should I use enamel or water based undercoat?

A. A solventborne enamel such as Resene Lusta-Glo will give you the hardest wearing topcoat, however if you do not want to use a solventborne topcoat then you can use Resene Lustacryl, the latter is a waterborne enamel and does not cure to be a hard as a traditional enamel paint but does have good wear characteristics and is low volatile organic content. After a degrease and a thorough sand, apply a full coat of Resene Quick Dry then you can apply two coats of either of the topcoat options.

June 2019

Q. I am repainting some concrete block work on my house. I purchased all the Resene paints I thought I needed, ( Resene Sureseal and Resene X-200).

However, after removing the old paint I can now see that the concrete blocks have been previously sealed by some sort of black, almost oily looking sealer.

I think this would have been done when the house was built in the 1980s. The paint came off simply using a waterblaster so I am concerned if I do not use the correct primer the new painting will fail also.

Should I use the Resene Sureseal or should I actually use Resene Membrane Primer? Looking at your tech specs, the Resene Membrane Primer might be correct, if the black stuff is what is referred to as ‘exposed bituminous membrane'. 

A. The black is probably old bitumen based waterproofing layer. To get adhesion of a waterborne paint system, you will need to use Resene Membrane Primer to prime bare bituminous areas.

June 2019

Q. I am painting the exterior weatherboards of my house using Resene Sonyx 101 in Resene Black White and wondered if there is a maximum time I can leave between coats? 

A. In theory, there is no maximum recoat time but we would normally recommend application of the second coat within four weeks. Ensure the first coat is washed down using Resene Paint Prep and Housewash diluted and used to label directions prior to applying the second coat to ensure the paint is cleaned from surface contaminants that may have settled on the first coat.

June 2019

Q. We have some steel lintels that support brick veneer on a house. We are replacing the windows with aluminium windows and having the steel lintels sandblasted and repainted. Do you have a cold galvanised type product you could recommend to apply to the steel lintels to the brick veneer?

A. We recommend Resene ArmourZinc 110 applied to achieve a dry film thickness of 75 microns.

June 2019

Q. I want to paint my front door entry.  If I use Resene Walk-on and add Resene SRG Grit do I need to undercoat first? The concrete is good condition, quite old though.

A. Ensure the concrete is clean and dry then apply a saturation coat of Resene Sureseal then finish with two coats of Resene Walk-on.

June 2019

Q. Can I paint bathroom wall tiles? What paint would you suggest I use?

A. Yes but not within the shower lining. Using Resene Interior Paintwork Cleaner ensure the surfaces to be painted are clean and free from grease, pay particular attention to hand contact areas.

Apply a thin coat of Resene Waterborne Smooth Surface Sealer and allow curing without water contact for at least 48 hours before over coating. The sealer is not designed to be applied as a thick wet film thickness or give opacity, the thinner the coat the better. Then apply two coats of Resene SpaceCote Low Sheen or Resene Lustacryl.

The new paint system will take five days to develop good initial adhesion and continue to cure for an additional three weeks until full cure occurs. In the early stages the paint surface will not have good resistance to cleaners or abrasion as these features develop as the film undergoes curing.

Note that painting will not reproduce the original features of the laminate.

June 2019

Q. I'm interested to learn more about your Resene Cemseal product. I would like to seal my interior concrete floor for a basic concrete finish look. Would this suit?

A. While Resene Cemseal is a sealer/dust proofing treatment for concrete floors it must fully penetrate the concrete as the product film is relatively soft and easily damaged.

Resene Concrete Wax may be a better option for what you are trying to achieve.

June 2019

Q. What paint spec do you recommend for the timber window reveals in an ensuite when we want to paint these a matt black colour? The window also faces north-west so will be prone to a lot of sun even though the window is double glazed with Low E so does have some UV protection/reduction.

A. For the best outcome the priming system should be envelope applied to seal off all faces. Prime with a coat of Resene Wood Primer and a coat of Resene Quick Dry primer undercoat and topcoat with two coats of Resene SpaceCote Flat Kitchen & Bathroom.

June 2019

Q. I am painting an iron roof that has some rust spots on it - can you please recommend how best to prepare/treatment required?

A. If any areas of moss or mould infestation exist then treat them with Resene Moss & Mould Killer diluted and used to label directions. For heavy infestations more applications may be needed.

Scrub down using Resene Paint Prep and Housewash diluted and used to label directions. Rinse clean or hose down with fresh water ensuring all salts are also removed.

All paint that is flaking or unsound must be removed by using mechanical methods, (3M Rust and Paint Removal Disc), chemical stripper or high pressure water-blasting taking care not to damage either the substrate or the surrounding areas.

Remove all areas of white corrosion material and as much red rust as is practicable and all paint that is flaking or unsound must be removed by using mechanical methods e.g. 3M Rust and Paint Removal Disc,  taking care not to damage either the substrate or the surrounding areas.

Where under-film corrosion is taking place the existing paint must first be removed as above and remove under film corrosion products taking care not to damage sound zinc coated areas. All paint edges must be feathered to a smooth finish.

June 2019

Q. I am repainting the outside of my son's house. I will be painting the wooden windows frames and external doors. My daughter in law has a 9-month-old baby and she does not like the smell of paint - what paint system would you recommend?

A. You can use Resene Quick Dry primer undercoat as the primer and then two coats of Resene Lustacryl. Both products are Environmental Choice Approved.

June 2019

Q. I have wooden slatted bunks which I am considering using as bridges over a stream. Is there a product which can be used to weatherproof the wood?

A. Timber exposed to exterior weathering needs to have a high level of timber preservative treatment to stop timber decay. There is no paint system that can be applied that will replicate the level required for exterior timber treatment. 

June 2019

Q. Can you give advice and the process for painting varnished interior doors in white?

A. Using Resene Interior Paintwork Cleaner, ensure the surfaces to be painted are clean and free from grease, pay particular attention to hand contact areas. A sand of the varnish to profile will also assist in primer adhesion.

Apply a thin coat of Resene Waterborne Smooth Surface Sealer and allow to cure without water contact for at least 48 hours before over coating. The sealer is not designed to be applied as a thick wet film thickness or give opacity, the thinner the coat the better. Then apply two coats of Resene Lustacryl.

The new paint system will take five days to develop good initial adhesion and continue to cure for an additional three weeks until full cure occurs. In the early stages, the paint surface will not have good resistance to cleaners or abrasion as these features develop as the film undergoes curing.

June 2019

Q. I'm adding kwila baseboards to an existing deck. The boards will be directly over newly laid concrete paving. Apart from waterblasting the new boards before fixing, what further steps should I take to prevent bleeding? 

A. Resene does not recommend waterblasting timber as this can damage the timber surface for subsequent coating. Scrub down using Resene Timber and Deck Wash diluted and used to label directions, to accelerate tannin removal.

June 2019

Q. I was wondering if you would be able to provide some advice around the Resene Forester colour range. I have exterior Shadowclad® plywood texture, but it has come with a primed coating. 

I want a stained look for the exterior, will the Resene Forester range work on primed Shadowclad®? Other companies I have spoken to, have said that their paint stain ranges won't work unless I was able to sand back the primer. 

A. Resene Forester can be applied to pre-primed Shadowclad®. The colour range available is essentially the Resene Woodsman exterior stain colours.

June 2019

Q. Should I use an undercoat on a wooden fence that has never been painted? The fence is 10+ years old and has weathered, I have waterblasted and it is solid and clean.  Should I use anything to treat the wood to prevent lichen? I have waterblasted it all off now. I am planning to paint with Resene Lumbersider.

A. We don't recommend waterblasting of timber, decks or fences as this has the potential to damage the timber and affect subsequent paint adhesion. Was the timber free of bio growth before waterblasting? If not then you will need to treat with Resene Moss & Mould Killer diluted and used to label directions.  We recommend a full coat of Resene Quick Dry be applied before applying the Resene Lumbersider.

June 2019

Q. I have a three storey, concrete block house that has been plastered over. It has been painted in the past with a flexible rubbery paint but needs to be redone. Can you suggest a similar flexible paint that will be able to be applied over the existing product?

A. The Resene equivalent product would be Resene X-300E.

June 2019

Q. I've built a sauna and I'd like to seal the walls and benches with something so I don't get stains. This is a dry sauna, not a steam room. There will however be some steam when throwing water on the heater. It needs to be something natural, preferably waterbased and not produce strong smells or cause irritation when in contact with bare skin. It shouldn't create a hard surface (like a lacquer) as this will become too hot to sit on. The sauna walls are untreated ply and the seats are also made out of soft pine.

Can you please assist with what to use for this?

A. The only product we would recommend for this application is four coats of Resene Polythane. The product is solventborne but cures via a reaction with atmospheric moisture and once cured will not release any solvents or materials that will impact upon the interior air quality.

June 2019

Q. I am adding a treated timber framed pergola to allow a deck to be covered. In a coastal town, what is the best type of Resene paint to use? Will it need an undercoat?

A. If the timber is treated pine then apply a primer coat of Resene Wood Primer and finish with two coats of Resene Sonyx 101 (semi-gloss) or Resene Lumbersider (low sheen).

We recommend using the Resene CoolColour™ version of the topcoat colour if you are looking to select dark finish colours. The CoolColour topcoat will not render the painted surface cool to touch but the CoolColour version will reflect more heat than the same colour made on non-cool technology. Dark colours may cause the rapid drying of damp timber with the ensuing danger of warping, though this effect will be lessened when a CoolColour is selected in place of a standard colour.

July 2019

Q. I have a block wall unit that isn't sealed properly from the outside, the condensation is coming through the blocks. I need to seal the blocks from outside with a paintable product that I can paint over etc.

A. Check pointing to make sure this is not a potential source of water. Then apply three coats of Resene X-200.

July 2019

Q. I am preparing to paint my garage roof and the corrugated iron has patches of surface rust so I want to know what product to use before painting. Do I need to use Resene Rust-Arrest and should I treat the whole roof or just the patches?

A. Wash down using Resene Roof and Metal Wash diluted and used to label directions. Remove all areas of white corrosion material and as much red rust as is practicable and all paint that is flaking or unsound this must be removed by using mechanical methods e.g. 3M Rust and Paint Removal Disc,  taking care not to damage either the substrate or the surrounding areas.

Spot prime prepared areas of corrosion using Resene GP Metal Primer then apply a full coat of Resene Galvo One and finish with two coats of Resene Summit Roof.

July 2019

Q. My powder coated, query aluminium roof was repainted in the past due to colour variations. It now has large areas of blistering substrate that looks like aluminium - is this possible?

If this is correct an etch primer will cause the existing acrylic system to curl at the edges of the bare areas.  Can I use Resene Galvo-Prime as I know it has great adhesion properties?  It will be repainted in an off white colour.

A. It could be aluminium (if you use a magnet you can confirm if it is aluminium) as it is often powder coated, but however cannot say with 100% accuracy. High pressure water blast (say 5000 psi) to remove loose paint, feather back edges where the paint has been removed then use Resene Galvo One as the primer, sorry not Resene Galvo-Prime.  Then topcoat.

July 2019

Q. What paint should I use for repainting interior window frames? I think the old paint on them is probably oil based.

A. Sand the existing paintwork to profile, dust off and apply a full coat of Resene Quick Dry and finish with two coats of Resene Lustacryl.

July 2019

Q. Does your product Resene Concrete Clear work on timber? We have some artworks painted on construction ply with pine frame; these will be attached to a fence and will be exposed to all weather conditions so I need to know if the product will protect the artworks from the elements. The timber is H3 and is painted with your testpots so there's no problem with the quality of the paint used.

A. We recommend Resene Clearcoat UVS applied to the painted mural.

July 2019

Q. We are getting a new COLORBOND® roof and gutters. I need to paint my steel fascia what prep/paint should I use?

A. If any areas of moss or mould infestation exist then treat them with Resene Moss & Mould Killer diluted and used to label directions. For heavy infestations more applications may be needed.

Scrub down using Resene Paint Prep and Housewash diluted and used to label directions. Rinse clean or hose down with fresh water ensuring all salts are also removed.

All paint that is flaking or unsound must be removed by using mechanical methods, (3M Rust and Paint Removal Disc), chemical stripper or high pressure waterblasting taking care not to damage either the substrate or the surrounding areas.

Remove all areas of white corrosion material and as much red rust as is practicable and all paint that is flaking or unsound must be removed by using mechanical methods e.g. 3M Rust and Paint Removal Disc,  taking care not to damage either the substrate or the surrounding areas.

Where under-film corrosion is taking place the existing paint must first be removed as above and remove under film corrosion products taking care not to damage sound zinc coated areas. All paint edges must be feathered to a smooth finish.

Note:  The performance of the subsequent paint systems will be largely dependent on the thoroughness of this surface preparation stage.

Ensure all edges of damaged paint are sound and immediately spot prime all areas of corrosion and any other bare metal with a full coat of the specified primer.

Spot prime areas of prepared carrion and bare metal with Resene GP Metal Primer then apply two coats of Resene Summit Roof.

July 2019

Q. How long can one leave Resene Sureseal exposed after application? It has been used on old primed but never painted weatherboards before overcoating in this case with Resene Lumbersider?

A. Of course the sooner the better, four weeks would be safe. The issue is degradation of the Resene Sureseal film due to weathering. If left beyond four weeks wash down using Resene Paint Prep and Housewash diluted and used to label directions to clean and remove any surface break down products. Beyond eight weeks re application of the Resene Sureseal would be recommended after the wash down.

July 2019

Q. We have polyurethane coated chipboard ceilings, with wooden beams. We want to paint them to lighten the rooms. There are some gaps between the beams and ceiling panels - my question is what do we seal the gaps with, and what paints and processes do we need to use for the ceiling and beams?

A. You can use the following system to paint a varnished substrate, using Resene Interior Paintwork Cleaner ensure the surfaces to be painted are clean and free from grease.

Apply a thin coat of Resene Waterborne Smooth Surface Sealer and allow curing without water contact for at least 48 hours before over coating. The sealer is not designed to be applied as a thick wet film thickness or give opacity, the thinner the coat the better. Then apply two coats of Resene waterborne topcoat paint.

The new paint system will take five days to develop good initial adhesion and continue to cure for an additional three weeks until full cure occurs. In the early stages the paint surface will not have good resistance to cleaners or abrasion as these features develop as the film undergoes curing.

The topcoats can be applied to cartridge filler that can be topcoated with a waterborne paint.  There is no need for Resene Waterborne Smooth Surface Sealer for painting cured sealants. There are often requests to fill the gaps in tongue and groove ceilings. The sealant often breaks as a result of movement of the tongue and grove boards even though it is extendable.

July 2019

Q. I am a sculptor and am am working on a community project involving a build using harakeke, which will be dyed in red. The project will involve local weavers. The dye needs to be protected from fading. Which of your varnishes would be most suitable? 

A. The easiest Resene product to use would be Resene Clearcoat UVS. The UVS additive in the clear will provide UV protection to pigments that are prone to colour fade when subject to exterior exposure. The product is only available as a gloss but if reduced gloss levels are required then the UVS Clearcoat can be over coated with Resene Concrete Clear to extend the gloss range of the finish.

We have not tested the adhesion of Resene Clearcoat UVS to harakeke (assume we are dealing with harakeke fibres) so this will need to be checked. If the dye to be used is water soluble then there will be dye bleed into the Resene Clearcoat UVS; this will need checking.

July 2019

Q. What Resene paint do I use on sheets of new Hardiflex?

A. This is the info on painting Hardiflex from the James Hardies installation manual; Use only quality exterior paints complying with AS 3730.

Manufacturer's specification for the selected paint must be followed. Note that some paints require undercoat before applying the finish coat. Prior to coating, the surface should be examined to ensure it is clean, dry and free of any dust or contaminants. When using PVC flashings, the light reflective value (LRV) for the colour must not be less than 40%.

Paints with a low LRV will absorb more solar heat and could cause the components used in the wall to expand or contract.

This combined with glossy paints and wet timber used at construction stage, could lead to increased chances of fastener read through as is common with any other building material.

There is an LRV (light reflection value) limit placed on topcoat colour selection, while Resene CoolColour™ technology allows for a given colour to be tinted to achieve a higher TSR (solar reflectance value) the LRV remains the same.

Our standard system for a cementitious based board is a coat of Resene Concrete Primer and two coats of Resene Sonyx 101 topcoat, we recommend using the CoolColour version of the topcoat colour if available.

The CoolColour topcoat will not render the painted surface cool to touch but the CoolColour version will reflect more heat than the same colour made on non-cool technology.

July 2019

Q. I manage a property which has some concrete steps which have been painted but the tenant complains they are slippery. I don't know the paint that was used and it has started flaking off. I have been googling anti slip ideas and came across your Resene Non-Skid Deck & Path Paint. Would it work if we painted over the existing paint? 

A. Strip the existing paint system by diamond grinding or chemical stripping. Check using the water splash test for the presence of a curing membrane, water splashed onto the concrete should immediately darken the concrete and be absorbed. If there is no darkening of the concrete, diamond grind to achieve a uniform surface profile similar to 180grit sandpaper. Ensure all grinding dust is removed, this may require wet mopping.

Then apply a seal coat of Resene Sureseal and two coats of Resene Walk-on or Resene Non-Skid Deck & Path if a higher level of wet slip resistance is required. The higher the wet slip resistance, the harder it will be to clean.

July 2019

Q. We have glazed terracotta tiles throughout the living areas of our home, stairs, bathroom and toilet areas. Is there a paint that will adhere to tiles that is hard wearing and doesn't chip easily?

A. Ensure the glazed tiles are thoroughly cleaned. Apply a thin coat of Resene Waterborne Smooth Surface Sealer and allow to cure without water contact for at least 48 hours before over coating. The sealer is not designed to be applied as a thick wet film thickness or give opacity, the thinner the coat the better.

Apply two coats of Resene Walk-on and finish with a thin seal coat of Resene Concrete Wax.

The new paint system will take five days to develop good initial adhesion and continue to cure for an additional three weeks until full cure occurs. In the early stages the paint surface will not have good resistance to cleaners or abrasion as these features develop as the film undergoes curing.

Note that painting will not reproduce the original features of the tiles.

Suggest that you initially undertake a small room to check that the system will meet your requirements.

July 2019

Q. I have a ceramic tile porch that gets extremely slippery when wet. What could I apply to it to give it more grip - preferably something almost clear?

A. Sorry but there is no slip resistant clear available, the addition of aggregate to achieve wet slip resistance does not then give an aesthetically acceptable clear finish. We do have fully pigmented systems, such as Resene Walk-on with Resene SRG Grit or Resene Non-Skid Deck & Path.

July 2019

Q. We have particle board floors in the upstairs of our new build. We want to seal these prior to carpeting to minimise potential formaldehyde and chemical leaching. What do you recommend?

A. The best sealer for formaldehyde is four coats of Resene Polythane.

While the data sheet does not make reference to its use for the purpose you require, the Polythane system was used to block formaldehyde release from flooring composites many decades ago when the flooring materials at that time contained much higher formaldehyde levels than now exist.

The product is solventborne so needs good ventilation during application.

July 2019

Q. What paint do I use as a sealer for new fibrolite?

A. We recommend Resene Concrete Primer.

July 2019

Q. We have new plasterboard and new plaster skim coats to seal. Can we use Resene Sureseal for these surfaces?

A. For wet areas e.g. bathrooms you must use Resene Sureseal. For non-wet areas you can use Resene Sureseal or Resene Broadwall Waterborne Wallboard Sealer.

July 2019

Q. We have old existing painted walls and ceilings (type of paint unknown), can we use Resene Quick Dry waterborne primer undercoat?

A. A full coat of Resene Quick Dry is recommended if the existing paint type cannot be identified. For best results sand the existing part to profile prior to applying the Resene Quick Dry.

July 2019

Q. We have spent some time sanding all the varnish off our plywood panels as we are going to now paint them with a Resene paint system. Can we use Resene Quick Dry waterborne primer on this surface as well?

A. Yes, you can use Resene Quick Dry waterborne primer as the primer for the sanded varnished ply.

July 2019

Q. A friend has asked if I can help repaint a dresser.  Have you any advice on what products to use as I assume the biggest challenge is to stop the 'wood' bleeding through to the colour? She is looking at a cream colour finish.

A. Degrease using Resene Interior Paintwork Cleaner then sand to profile for painting. Then apply a coat of Resene Quick Dry and finish with two coats of Resene Lustacryl tinted to the required topcoat colour.

Not sure of the potential for colour (tannin) bleed to occur from the base timber but if you apply the Resene Quick Dry waterborne primer and there is no discolouration of the primer then you can proceed with topcoating.

If there is tannin bleed apply a coat of Resene StainLock then follow with the two coats of topcoat.

July 2019

Q. We have bricks on our ground level and blocks on our basement. I wanted it to be the same colour as the brown red bricks. Can we paint on top of Resene X-200 with a desired colour?

A. Resene X-200 can be topcoated with any Resene exterior waterborne paint.

July 2019

Q. What paints are needed on new raw cedar shingles? Sealer? Undercoat?

A. For a solid paint finish, apply a prime coat of Resene Wood Primer then a coat of Resene Quick Dry waterborne primer undercoat and finish with two coats of Resene Lumbersider tinted topcoat colour. If selecting a dark colour as the topcoat colour use a Resene CoolColour™ version of the topcoat colour.

The CoolColour topcoat will not render the painted surface cool to touch but the CoolColour version will reflect more heat than the same colour made on non-cool technology.  Dark colours may cause the rapid drying of damp timber with the ensuing danger of warping, though this effect will be lessened when a CoolColour is selected in place of a standard colour.

July 2019

Q. We have put cork tiles down in a caravan and have done some test colours/stains on spare pieces. We prefer the look of Resene Aquaclear with black Resene Colorwood Enhance, as opposed to the black Resene Colorwood stain with a 'varnish' over the top.  Can we use Resene Aquaclear with black Resene Colorwood Enhance for the first coat and then do topcoats of Qristal ClearFloor 1K? Or can we add the black Resene Colorwood Enhance straight into Resene Qristal ClearFloor 1K? Would Resene Aquaclear (satin) be an OK final finish on the cork floor in the caravan (which will get periodic rather than everyday use)?

A. Yes to all these queries – Resene Colorwood Enhance can be used in Resene Aquaclear and Resene Qristal ClearFloor 1K.  Resene Aquaclear can be used on flooring.  Resene Qristal ClearFloor 1K is more durable than Resene Aquaclear on flooring.

July 2019

Q. We recently had a professional painter apply Resene Write-on Wall Paint which we cured for almost two weeks. We used the pens that came with the paint and now are unable to get the markers to wipe off the surface. What can we do?

A. Removal of marker residues can be difficult if there is an orange peel present from the underlying basecoat paint system.

The mixing of the Resene Write-On Wall Paint base and hardener must achieve a final mix in the correct ratios; if this is not achieved then the film does not cure to give the required properties.

We have seen this before fixed by application of another coat of Resene Write-On Wall Paint, ensuring complete mixing to the Resene mixing instructions. Prior to recoating, remove marker pen residues by wiping with meths and a cloth then lightly sand the existing Resene Write-on Wall Paint before applying the additional coat.

July 2019

Q. Could you please advise what product I should use to paint a tiled fireplace surround? I can maintain hand contact when the fire is on so it doesn’t get too hot. The tiles don't look glazed or at least aren't glossy.

A. We recommend you apply a seal coat of Resene Sureseal and finish with two coats of Resene Lusta-Glo in your selected colour. Paler colours may yellow upon ageing. The degree and onset of yellowing will be determined as the paint becomes warm. There will be a period of release of a solvent type odour which will dissipate over time; good ventilation is recommended for early use.

July 2019

Q. I have a wooden stairway banister varnished in 'rimu' coloured polyurethane. I want to change the colour to a dark wood finish without major sanding work. Is there a Resene product that would suit and how would it be applied (brush, sponge etc.)? 

A. I recommend you can visit a Resene ColorShop and look at the Resene Colorwood Enhance samples on the Resene Woodcare stand.

You will have to degrease the hand rail and sand to achieve a profile for recoating. You do not need to sand the existing varnish system off to bare timber.

Then apply 1-2 coats of Resene Colorwood Enhance colour that suits what you are trying to achieve. One Resene Colorwood Enhance colour pottle is added per litre of Resene Aquaclear waterborne varnish (can be added to any of the sheen versions available in the product, but I recommend that the semi-gloss would be the best to achieve good wear characteristics).

July 2019

Q. I am looking for a child safe stain for wooden blocks in brilliant colours

A. We recommend Resene Colorwood wood stain.

August 2019

Q. Can you please recommend what paint system I should use to paint a previously unpainted plywood garage floor? The garage parks two cars. I will sand it down to a clean wooden surface before painting. Can I use an epoxy resin system?

A. Epoxy paint systems are relatively inflexible and if applied over a substrate that has the potential for flexing/deformation the epoxy paint will crack. Suggest that after sanding apply a full coat of Resene Quick Dry and then follow with two coats of Resene Uracryl 402.

Allow a five day cure after application of the last coat of Resene Uracryl before driving onto the floor.

August 2019

Q. I have two faded rimu cabinets painted with two pot lacquer.  I would like to renovate them with a colour. Is it possible to paint with a coloured two pot or will they have to stay lacquered?

A. Degrease and a through sand should then allow re painting with a two pack topcoat. However as the solvent resistance of the existing lacquer cannot easily be checked there may be a possibility that the solvents in the two pack topcoat may react with the lacquer.

August 2019

Q. Could you advise product to seal and protect tanalised flooring grade plywood?

A. We recommend Resene Wood Primer.

August 2019

Q. Do you have, or can you recommend a clear finish suitable for use on a timber vanity top?

A. We recommend Resene Polythane.

August 2019

Q. I have a previously polyurethaned wooden benchtop to sand back and recoat. Which clear product is best suited for this area? The bench surrounds the kitchen sink and has a little water wear to the previous coating around the edge of the sink.

A. Assuming that you are wanting to recoat with a clear system, the best product for this application is 3-4 coats of Resene Polythane.

August 2019

Q. I am preparing and treating rust stains before painting the exterior of my house. What is the correct way to deal with these rust stains before I paint? The rusting looks to be from non-galvanised nails attaching the exterior fibre cement cladding.

A. Wash down all surfaces to be painted using Resene Paint Prep and Housewash diluted and used to label directions. Using wet and dry sandpaper sand the nail heads to remove surface corrosion, then spot prime nail heads with two coats of Resene GP Metal Primer before topcoating.

August 2019

Q. I want to whitewash my matai floorboards. Which products do you recommend?

A. Apply Resene Colorwood Rock Salt stain then overcoat with 3 coats of Resene Aquaclear. You can add 1 pottle of Resene Colorwood Enhance White per litre of Resene Aquaclear to one or more coats of the Resene Aquaclear to get an increase in the depth of whiteness.

Q. I need to paint an 80 square metre small concrete tennis court and I intend to purchase green and white Resene paint. The paint will be applied (sprayer/roller) to a new concrete pad. Is there a durable purpose designed paint for a court and what prep needs to occur beforehand?

A. Resene Tennis Court Coating is formulated to give a slip resistant surface texture for tennis courts. Resene Lumbersider can be used for white line marking.

The court paint is not designed to be spray applied, apply a full seal coat of Resene Sureseal before applying the two coats of topcoat paint.

Check using the water splash test, for the presence of a curing membrane, water splashed onto the concrete should immediately darken the concrete and be absorbed. If the water is not immediately absorbed and the wet concrete does not darken, then this indicates the presence of a curing membrane. Then diamond grind to remove the curing membrane to achieve a uniform surface profile, similar to 180grit sandpaper. Ensure all grinding dust is removed, this may require wet mopping.

August 2019

Q. Can I use Resene Lustacryl semi-gloss waterborne enamel over sound, oil based enamel?

A. Yes you can; however all old enamels need to be thoroughly sanded to a uniform dull finish, prior to applying the new coating (so the new coating adheres to the old).

It's often difficult to achieve this completely so is a good idea to use a primer first prior to the Resene Lustacryl. Resene Quick Dry primer would be best. Sand the old enamel as best you can, prior to applying Resene Quick Dry.

August 2019

Q. I have beige wall tiles in my kitchen and I would like to change the colour. Is this possible? I did purchase Resene Waterborne Smooth Surface Sealer as a primer. Can you advise what paint I would use after the primer?

A. Using Resene Interior Paintwork Cleaner ensure the surfaces to be painted are clean and free from grease, pay particular attention to hand contact areas.

Apply a thin coat of Resene Waterborne Smooth Surface Sealer and allow to cure without water contact for at least 48 hours before over coating. The sealer is not designed to be applied as a thick wet film thickness or give opacity, the thinner the coat the better. Then apply two coats of Resene SpaceCote Low Sheen or Resene Lustacryl.

The new paint system will take five days to develop good initial adhesion and continue to cure for an additional three weeks until full cure occurs. In the early stages, the paint surface will not have good resistance to cleaners or abrasion as these features develop as the film undergoes curing.

Note that painting will not reproduce the original features of the tiling.

August 2019

Q. I am wanting to paint the skirtings and doors in a 1950 house which are possibly stained or varnished.  How do I go about this?

A. Ensure the surfaces are clean and grease free then apply a coat of Resene StainLock followed by two coats of Resene Lustacryl.

August 2019

Q. I'm looking at painting concrete posts.  Will I need to put a concrete primer on first then the colours I'm needing?

A. For new concrete apply a full coat of Resene Concrete Primer, then two coats of Resene Sonyx 101.

August 2019

Q. What paint do you recommend on James Hardie Stria and Axon?

A. For new a primer coat of Resene Concrete Primer and two coats of Resene Sonyx 101 semi-gloss or Resene Lumbersider low sheen.

We recommend using the Resene CoolColour™ version of the topcoat colour when selecting dark topcoat colours.  The CoolColour topcoat will not render the painted surface cool to touch but the CoolColour version will reflect more heat than the same colour made on non-cool technology.

August 2019

Q. Is there any specific Resene colour/range for weatherboard exterior painting in terms of durability?

A. There are two components to durability, time to the onset of chalking and colour fastness. The higher the gloss level the longer the time to the onset of chalking.  Given this, we recommend Resene Sonyx 101 semi-gloss as the exterior paint as the gloss level of the product gives an excellent balance between a low sheen and full gloss exterior acrylic from the time to onset of chalking.

Colour fastness is determined by the colourants used to make up a given colour, Resene high quality colourfast pigments to produce our colourants so that tinted colour has the best resistance to exterior colour fade.

There is no correlation or grouping of colours to answer your question re specific colours, to achieve the best exterior durability as this is a function of the product and the tinted colour. Suppliers of finger jointed weatherboards have a limitation of the LRV (light reflectance value) that they will give their cladding guarantee for. Typically, this is a minimum LRV of 45% and this restricts colour choice to lighter colours. The restriction is based on the effect that heat attracted by application of darker colours, will have on the timber cladding stability.

August 2019

Q. What paint type should I use on Onduline fibre cladding?

A. A primer coat of Resene Galvo-Prime and then two coats of any Resene exterior waterborne paint, we strongly recommend using the Resene CoolColour™ version of the topcoat colour if selecting darker topcoat colours.

The CoolColour topcoat will not render the painted surface cool to touch but the CoolColour version will reflect more heat than the same colour made on non-cool technology.

August 2019

Q. We are having a macrocarpa tongue-and-groove ceiling installed and I would like to know which is the best product to use for oiling or staining and ease of use and touching up later?

A. For oiling, we recommend Resene Danska Teak Oil. For staining, we recommend Resene Colorwood stain overcoated with Resene Aquaclear waterborne varnish.

August 2019

Q. I am painting an unpainted concrete tank. Do I have to seal first or use an undercoat like normal painting? I am going to be using Resene Lumbersider paints.

A. If the concrete is new and sound, apply a primer coat of Resene Concrete Primer then two coats of Resene Lumbersider topcoat.

If old/weathered, treat with Resene Moss & Mould Killer. If algae/mould is present then apply a coat of Resene Sureseal before overcoating with the topcoats.

August 2019

Q. The concrete blocks on the ground floor of our 1980s style home have been painted but the paint is now faded and needs repainting. We have a dehumidifier working on the inside to take care of any moisture which must be coming through the blockwork. What is the best option to seal the outside?

A. Check that there is no pointing defects (pointing is the mortar that holds the bricks together) that may be allowing moisture ingress. If the pointing is sound, wash the existing paint down using Resene Resene Paint Prep and Housewash diluted and used to label directions to achieve a clean, chalk free surface then apply three coats of Resene X-200.

August 2019

Q. Is there a brand specific whiteboard marker that you can recommend that is best to use on the writeable paint?

A. MaxiFlo is the brand we recommend. The ease of dry marker removal will depend upon the smoothness of the Resene Write-On Wall Paint finish.

August 2019

Q. I have just had my house re-clad with new timber. I am wondering about the thickness of the paint on the weatherboards because I have noticed that I can sometimes see where the nails have been puttied over - usually early in the morning. Could this mean that there is insufficient paint? Can it easily be checked?

A. There is no testing equipment to check the dry film build, of paint over timber substrates; nail heads are too small in diameter to use standard film thickness testing equipment for metal substrates.

It is possible that there is a slight difference in the gloss level of the paint over filled nail heads, this may be seen when the nail hole area is wet with dew or when looking down the walls (side sheen).

August 2019

Q. What is the recommended paint system for new Hardigroove?

A. The recommended paint system for new exterior Hardigroove, is to apply a coat of Resene Concrete Primer then finish with two coats of Resene Sonyx 101 semi-gloss or Resene Lumbersider low sheen.

August 2019

Q. I have a previously painted deck which needs repainting. Is Lumbersider the best product for this?

A. We usually recommend Resene Walk-on for decking but we know that Resene Lumbersider is commonly used.

August 2019

Q. Our deck is Fijian mahogany and needs cleaning. Salty air, some sand and pollen have made it look awful. I do have a waterblaster but am reluctant to use it, or any product, that will compromise the oil. What do you suggest? Soap and a broom will test my ability but not impossible. Is there some cleaning product you would recommend?

A. Resene Timber and Deck Wash can be used for general clean-up of exterior decking.

August 2019

Q. Can I add coloured paint e.g. a Resene testpot of Resene Lumbersider to Resene Aquaclear to colour it?  I know there are Resene Colorwood stains that you can apply under Resene Aquaclear and colour enhancers that you can add to Resene Aquaclear but these will not work in my situation. I want a slightly more 'solid' look without a complete paint finish look.

A. There is a good chance this will be okay but we have never tried this combination. The lower the amount of waterborne paint that is mixed, the less risk there is. Stability could be an issue, so would advise using soon after mixing.

August 2019

Q. I have a 20 year old home which has lovely hollow core, interior, polyurethaned rimu doors. We are redecorating the interior of the house but it looks like the doors will need to be painted. We like the look of the Resene limed finishes which still retain the wood grain look but somewhat darker. How do we prepare the doors for this type of finish? We are hoping there is a solution or reluctantly we will just paint over.

A. Resene Colorwood Whitewash is a possibility but it cannot be tinted to a colour.

The existing clear coat will need to be thoroughly degreased using Resene Interior Paintwork Cleaner, paying particular attention to areas of hand contact. Then sand using 220 grit sandpaper to profile the clear coat for recoating (sand to de-gloss not to remove).

Apply a full even coat of the Resene Colorwood Whitewash, making sure to brush out areas of overlap, as these will appear as a whiter line compared to adjacent areas followed by a coat of Resene Aquaclear in your preferred gloss level.

August 2019

Q. I have a renovation project where we are cutting into an existing concrete wall to form a door opening at an existing window. We anticipate some cut ends of steel.

What is the best paint system to specify to seal the opening, prior to installing the new door joinery?

A. Cut ends will need to be profiled using emery paper then apply three coats of Resene Armourcote 221 epoxy primer.

August 2019

Q. Can I put wallpaper straight onto new plasterboard?

A. No, the stopped plasterboard will need to be sealed with Resene Sureseal. This is a recommendation from the wallpaper supplier

August 2019

Q. I'd like to come into a store this week to grab some testpots in primary colours to paint a placard for an event. I'm thinking I'd like to get your standard Resene Black and Resene White shades, and shades such as Resene Happy, Resene Pursuit and Resene Half Resolution Blue.

I understand this might not be a query you get every day... but I was wondering if any of your paint formulas contain any animal-derived products/ingredients. Is it possible for me to get these shades, or similar, in a formula that doesn't contain any animal products? In regards to colour, I understand some reds might be animal-derived - do you have a vibrant red that doesn't contain animal products?

A. There are no raw materials derived from animals in any of these paints.

August 2019

Q. I'm interested in purchasing some homemade untreated timber planter boxes for my garden. What would be the best product choices/options for finishing the planters so that they do not rot too quickly? I would be especially interested in low toxicity options, so that I could possibly grow vegetables in the boxes.

A. The reality is that biocides are required to reduce the decay potential of timber.

The prevention/reduction of wood decay on the outside of the planter boxes can be achieved using standard wood primers, these will not release chemicals that can then pass through the timber to the growing mixture for possible uptake by vegetables. So for the exterior surface you can use Resene Quick Dry Primer, overcoated with Resene Lumbersider for colour. Alternatively, if you want a semi-transparent stain finish, use Resene Waterborne Woodsman.

The main concern for the interior facings would be when growing root vegetables. We have no test data for any of products to relate uptake by root vegetables. From experience over time, even treated timber for in ground use, does undergo decay when used for planter boxes filled with soil. A possible suggestion is to get a thick black plastic sheeting to line the inside of the planter box before filling, making sure drainage holes are punched in the bottom section.

August 2019

Q. What primer do I use on a timber door using Resene Uracryl 402 as a topcoat?

A. We recommend Resene Quick Dry, leave the primer to dry for at least 48 hours before applying the first coat of Resene Uracryl 402 topcoat.

August 2019

Q. What is the best Resene paint to paint my gutters/spouting? The spouting has already had a coat of paint 7 years ago but I'm unsure of whether this was water or oil-based paint. I'm looking at having a copper type look so if you can recommend something it would be appreciated.

A. As long as the painted guttering surfaces are clean and the existing paint system sound we would normally recommend Resene Sonyx 101 as the topcoat.

August 2019

Q. Can I paint an inside hallway and bedroom with a flat paint finish if so what one is best?

A. Yes you can.  We recommend Resene SpaceCote Flat.

August 2019

Q. Our school is working on designing and painting a mural with Resene paints for your mural competition.

We have some questions regarding materials and paints:

  • Which board we can use to screw up on an exterior wall getting full on east sun.
  • What undercoat do we seal it with and how many coats does it require?
  • Are all Resene shelf line paints good for exterior use on the mural?

A. Best to use quality exterior grade plywood as the board.

Prime all sides of the board with Resene Quick Dry (back and front faces, edges) with a full coat of Resene Quick Dry primer undercoat.

For the mural you can use any of the Resene exterior waterborne paints, Resene Hi-Glo, Resene Sonyx 101 or Resene Lumbersider along with Resene testpot colours.  Most murals are created using Resene testpots and Resene Lumbersider.  Most Resene testpots are made using Resene Lumbersider.

August 2019

Q. We are making toys for children and want to know what the safest paint and stain is with varnish we can use for the toys.

A. Resene Colorwood stains for staining and Resene Aquaclear waterborne varnish for clear coating. Both products have Resene Environmental Choice approval.

August 2019

Q. I would like to paint our radiators to match our wall colour. They are new radiators, glossy white. What sort of paint product would be best to use please? They are located throughout our house in bedrooms; office; hallway and bathrooms.  The radiators don't ever get so hot they can't be touched. I'd say it's similar to a standard oil heater, in terms of heat level.

A. Using Resene Interior Paintwork Cleaner, ensure the surfaces to be painted are clean and free from grease, and pay particular attention to hand contact areas.

Apply a thin coat of Resene Waterborne Smooth Surface Sealer and allow curing without water contact for at least 48 hours before over coating. The sealer is not designed to be applied as a thick wet film thickness or give opacity, the thinner the coat the better.

Then apply two coats of Resene SpaceCote Low Sheen tinted to your required colour.

Not sure how practical the system will be to apply to the radiator configuration you have but this is our recommended system.

August 2019

Q. The internal doors in my home are stained timber, with what appears to be a varnish finish. We wish to change the doors to a paint type finish. Could you tell me how I should proceed and whether oil based or water based paint should be used?

A. Using Resene Interior Paintwork Cleaner, ensure the surfaces to be painted are clean and free from grease, and pay particular attention to hand contact areas.

Apply a thin coat of Resene Waterborne Smooth Surface Sealer and allow curing without water contact for at least 48 hours before over coating. The sealer is not designed to be applied as a thick wet film thickness or give opacity, the thinner the coat the better. Then apply two coats of Resene Lustacryl.

The new paint system will take five days to develop good initial adhesion and continue to cure for an additional three weeks until full cure occurs. In the early stages the paint surface will not have good resistance to cleaners or abrasion as these features develop as the film undergoes curing.

August 2019

Q. Which product would be suitable for painting behind tanalised timber retaining walls, prior to back-filling in order to give greater protection; I'm thinking something like tar or pitch. Would you have any suggestions?

A. We recommend Resene Water Lockout.
