How To Guides

Repainting interior and weather affected surfaces

The products you will need to use depend on whether you are painting over affected surfaces or painting new surfaces. Refer to the below information, in conjunction with label instructions, to guide you in your product selection.

Advice for repainting existing surfaces

Conduct an adhesion test

Conduct an adhesion test on all previously painted surfaces. To do this, ensure surface is sound by cutting a small X through the existing paint with a sharp blade, press sticky tape firmly across the cut and then rip off the tape. If the paint comes off, it is unsound and should be removed. Repeat at random in a number of areas to test the surface.

Scrape off

Scrape off all loose and flaking paint and ensure surface is dry. If you are unsure, we recommend that you contact your local qualified tradesperson.

Does the substrate exhibit mould?

Wear gloves and goggles

Wear gloves and goggles as you wash the surface with Selleys Original Sugar Soap® and rinse with clean water to remove any dirt, oil or grease. In cases where mould or mildew is present, use a household bleach solution: Dilute 1 part bleach with 3 parts clean water.

Use a scouring pad

Use a scouring pad wet with bleach solution to lightly scrape the surface and ensure physical removal of stubborn areas of mould growth.

Removing

Leave the bleach solution on the surface for 15 minutes, then thoroughly remove by washing down with clean water and wipe dry. In very severe cases, repeat this action to remove all mould.

Scrape and sand down

Scrape and sand down any loose, peeling and flaking paint.

Filling

Fill any cracks or holes with a suitable filler.

Dust off

Sand gloss and semi gloss finishes to a dull flat finish to allow a sound surface before top coating. Dust off.

Prime the surface

Prime the surface with Dulux PRECISION Stain & Mould Blocker®.

Discourage the regrowth of mould

Does the substrate exhibit stains?

Ensuring

Firstly ensure that you know the source of the stains e.g. water.

Check the adhesion

Check the adhesion of the existing paint by doing an adhesion test (refer to ‘Determine if the surface is sound’ section above). If the existing coating is sound, you then need to wash the surface down with Selleys Original Sugar Soap and allow it to dry.
