Maintenance guide for Resene paint finishes
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.

Cleaning interior paintwork
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 and develop their ultimate film properties. Cleaning of fresh paint films will damage the paint and this may require repainting to restore the desired level of finish.
Steps for cleaning interior paintwork:
2. Dip a soft lint free cloth, such as a Jif Ballerina, into the Resene Interior Paintwork Cleaner solution. Do not saturate the cloth as this could lead to runs and streaking. If using a spray pack, apply Resene Interior Paintwork Cleaner direct to the surface you wish to clean.
3. Using light strokes, thoroughly wipe the area to be cleaned turning the cloth frequently to maintain a clean edge. Wipe away any excess solution. Wring the cleaning cloth out into an empty bucket before dipping it into the detergent solution again. This will minimise the appearance of streaks.
4. In order to achieve an even finish, dry the surface with one final wipe using a soft dry lint-free cloth in the direction of the paint flow. 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.
Cleaning 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 the exterior 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. Ensure any residue is properly washed off any windows or other glass surfaces,
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.
The first few months post painting
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 UV 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. This glaze is available in a gloss version and may be applied over any of the Resene premium waterborne finishes.
Surfactant leaching is usually associated with marginal painting conditions. Paint colours that require higher levels of tinters 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 the cleaning recommendations overleaf.
Recommended maintenance schedule for steelwork
Maintenance schedule five year system
Repeat inspection process at year 5 and based on the results of this condition survey make a decision on future maintenance actions, which may include touch up/repair of areas or a full recoat.
Maintenance schedule ten year system
Year 4 repeat full inspection and repair areas of damage/coating breakdown as per year 1/2.
Repeat condition survey at year 6/7 and repair as necessary to maintain integrity of painted areas.
At year 9/10 a full inspection by a qualified Coatings Inspector or Coatings Technician should be undertaken to arrive at a condition status. This survey should address future maintenance requirements beyond the initial system lifetime and at this point decisions on touch ups/repair of areas or full recoating can be made.
