Cleaning your home’s interior paint

1. If using Resene Interior Paintwork Cleaner ‘concentrate’, dilute before use. For light soiling dilute 1:60 with water; for medium soiling dilute 1:50 (approximately one teaspoonful to one cup) with water; for heavy soiling dilute 1:40 with water. If using Resene Interior Paintwork Cleaner ‘ready to use’ no further dilution is required.

2. Dip a soft lint-free cloth 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.

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 paint

Like washing your car, cleaning your house will help it maintain its good looks for much longer. Airborne contaminants, including salt deposits, which settle on your paint film, can attack the surface and cause premature breakdown. Annual washing of your home will help maintain the fresh appearance of your 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 or brush. 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.
