Caring for your Resene paint finish
Thank you for choosing to use a Resene paint. You have made the first step towards having an attractive, durable paint finish that will give you many years of satisfaction.
Follow the care and cleaning recommendations in this brochure to help you keep your Resene paint finish looking its best for longer. Avoid cleaning the paint finish until at least four weeks after application to ensure it has had sufficient time to fully develop its properties. Keep any cleaning to a minimum to avoid damaging the paint film. If you have sensitive skin, wear gloves when using cleaning solutions to avoid irritation.
If you require any product application advice or have any further questions, please contact your local Resene ColorShop or Reseller or in Australia: call 1800 738 383 or visit www.resene.com.au; in New Zealand: call 0800 RESENE (737 363) or visit www.resene.co.nz.
Cleaning your home's interior paintwork
If trying to remove a localised mark, start from a radius wide of the mark and work towards it. This will minimise any ‘tide mark’ that might develop.
Be aware that walls, like windows, can accumulate a faint layer of dust or grime. A seemingly minor job of cleaning a small spot can lead to a major cleaning job! If unwillingly caught in this predicament, a feather duster can sometimes minimise the boundary between the cleaned and uncleaned areas.
Always test the cleaning method in an inconspicuous area to ensure the cleaning process you plan to use does not damage the finish of the paint. Wait until the test area has dried before using the same technique on more conspicuous areas. Walls may appear discoloured as they absorb the water, but should dry back to their original colour.
Do not vigorously scrub the surface nor use an abrasive or strong cleaning agent as you may burnish the paint surface and mar the paint finish. Do not wash walls for four weeks after painting, as waterborne paints require this period of time to fully cure.
Cleaning your home's exterior paintwork
Moss and lichen can penetrate the surface of the paint film, damaging its integrity and reducing the useful life of the film, while mould growth can destroy the chemical entity of the resin system that holds the paint system together. The presence of moss, mould and lichen will hold moisture on the surface longer, promoting further growth of these organisms and increasing the risk of damage to the coating. Removal using the appropriate washing procedure will increase the life of the coating and maintain the aesthetic properties of the paint finish.
For an instant fresh appearance, regularly wash down your home with Resene Paint Prep and Housewash diluted as recommended with water. Apply the diluted solution with a soft broom. Wash off with copious amounts of freshwater.
For a slower-acting, longer-term clean, use Resene Deep Clean. Designed for general maintenance of exterior weathered surfaces, Resene Deep Clean is a slow release cleaning agent. Simply apply Resene Deep Clean diluted as recommended with water to weathered exterior areas, such as discoloured cementitious surfaces or lightly moss infested walls, and leave. The combination of Resene Deep Clean and natural weather conditions will slowly break down surface contamination leaving a Resene Deep Clean cleaner surface.
Most detergents can have a negative effect on fish life so avoid letting the washings run off into the stormwater system.
Attend to areas of flaking paint, stained paint (treat the source of the stain, then touch-up the paint finish as required), moss and mould, and rotten areas of timber.
Moss and mould will grow through the paint surface and if left untreated will ruin the fresh appearance of the paintwork. If major moss and mould infestations appear, treat them with Resene Moss & Mould Killer diluted as directed with water. Wash off with copious amounts of freshwater.
Bleach is a very effective moss and mould killer, however residues can decolourise subsequently applied paint finishes, particularly when used over a porous surface. If you are repainting, ensure all bleach treated surfaces are allowed to weather and/or are thoroughly rinsed prior to repainting.
If you are planning to wash down a freshly painted house or building, wait at least four weeks from the completion of the painting job to give the paint time to fully cure. If debris is being carried onto the building during painting, cease work and restart when the air is clear. Debris carried onto a wet building may be trapped into the paint film and will be impossible to remove later without removing the paint finish itself.
Resene paints are developed and manufactured to exacting quality
standards to ensure every can of paint is full of Resene quality. During
the first few months after your paint has been applied, any of the
following may occur, all of which are quite natural and do not imply
Surfactant leaching is caused by water sitting on freshly applied waterborne paints. Water softens the fresh paint and draws out water soluble surfactants. As water dries off these are deposited on the surface. These deposits are easily removed early on by simply cleaning the surface following the interior paintwork instructions. The problem may occur once or twice again before all leachable material is completely removed. If left, the deposits may etch the surface and leave a permanent mark. This should diminish over a few months and is only of cosmetic concern.
Surfactant leaching is usually associated with marginal painting conditions. Tinted paints are more prone to surfactant leaching than are white paints because of the ingredients that are present in tinters. To prevent surfactant leaching, it is best to avoid application in the late afternoon if cool, damp conditions are expected in the evening or overnight. Ensure adequate ventilation is maintained during the drying period. If surfactant leaching does occur, clean the surface as soon as possible to avoid permanent marking using these cleaning recommendations.
Large amounts of moisture are generated during the interior decorating process. It is critical that good ventilation is maintained throughout the drying period. The best way to achieve this is to open windows to encourage airflow and use heaters to warm the air temperature. If ventilation is poor, the paint finish may not fully cure.
Excess moisture can lead to surfactant leaching, blistering and mould problems.
While dampening a porous surface can ease paint application in exterior situations, paint will never cure over a permanently wet surface and blistering may result, particularly on horizontal surfaces where water is liable to pond.
Resene paints are designed to resist fading, however the combined presence of strong U.V. light and lime in the surface can lead to premature fading. Sometimes lime staining is mistaken for fading. Lime staining occurs when the lime in the surface has leached through and is deposited on top of the paint surface as a white deposit that looks similar to fading. If this occurs, the lime must be blocked off with a suitable paint system. Resene recommends all fresh plaster surfaces are coated with Resene Limelock first.
Resene Sun Defier U.V. protective glaze may be used as a finish coat over freshly painted bright organic hues and shades to protect these more vulnerable pigments against fading.
Paints are essentially a combination of pigments – colour particles held together by the paint resin as the paint dries a thin layer of clear resin is left on the surface and the colour pigments are locked in below this layer. After years of sun and moisture degradation this thin resin layer simply wears or erodes away – exposing the pigments below and as they are no longer bound into the paint film by the resin they are easily wiped off and this is what is referred to as chalking. This slow erosion is much more preferable than cracking or flaking and, provided the surface is sound and cleaned, once the chalk is removed it is ideal for painting over. Chalking is generally worse when enamel paints or lower sheen waterborne paints have been used.
Taking a shortcut, such as skipping a primer or topcoat of paint because the paint seems to have already covered or to save time or money, can cause premature chalking. Over a porous surface the paint resin may be absorbed into the surface, which will reduce the amount of protection on top of the surface. It’s always best to apply the full system recommended as cutting corners does not save time or money - it ultimately costs because you will need to redecorate earlier.
Chalking is more common with flat paints and white or very light-coloured paints that contain high levels of titanium dioxide and extenders. A low degree of chalking is often beneficial to whites and off-whites, since it tends to rid the surface of a certain amount of dirt and mould.
Excessive chalking is detrimental because chalk can run-down onto the underlying structure (e.g. brickwork) and deface the appearance of the surface, it can lighten the colour of the paint and/or it can erode the paint film resulting in a loss of protection to the substrate.
Chalk needs to be removed before repainting and can be considered to be in the same category as dust and dirt. Use Resene Paint Prep and Housewash to clean off the chalk. If the surface is badly chalked, it may be time to consider a clean and repaint.
