Advice for painting affected surfaces

1. Determine if the surface is sound
Conduct an adhesion test on all previously painted surfaces. Ensure surface is sound by cutting a small X through the existing paint with a sharp blade, press cellulose 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 all loose and flaking paint and ensure surface is dry. 
2. Does the substrate exhibit mould?

Mould 

Step 1: Prepare the surface:
Wash down with 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.
Wear gloves and goggles.
Use a scouring pad wet with bleach solution to lightly abrade the surface and ensure physical removal of stubborn areas of mould growth. 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 any loose, peeling and flaking paint.
Fill any cracks or holes with a suitable filler.
Sand gloss and semi gloss finishes to a dull flat finish to allow a sound surface before top coating. Dust off.

Step 2 Undercoat:
Dulux 1 Step Acrylic Primer Sealer Undercoat to any areas which have been repaired or which have an uneven gloss level.
Areas where paint has peeled, seal with Dulux Sealer Binder.
If residual stains are left, spot undercoat with Dulux 1 Step Oil Based Primer Sealer Undercoat to "seal" the stain before applying a topcoat.

Step 3 Topcoat:
To discourage the regrowth of mould in cool, damp or humid areas, apply Dulux Wash & Wear Kitchen & Bathroom.
For all other areas, apply Dulux Wash & Wear

3. Does the substrate exhibit stains?
Stains

Step 1: Prepare the surface:
Firstly ensure that you know the source of the stains e.g. water.
Then check the adhesion of the existing paint by doing an adhesion test refer 'Check if your old paint is sound' If the existing coating is sound, you then need to wash the surface down with sugar soap and allow to dry.

Step 2 Undercoat:
If residual stains are left, spot undercoat with Dulux 1 Step Oil Based Primer Sealer Undercoat to "seal" the stain before applying a topcoat.

Step 3 Topcoat:
In cool, damp or humid areas, apply Dulux Wash & Wear Kitchen & Bathroom.
For all other areas, apply Dulux Wash & Wear
