The fix, step by step.
Pick a brand to see the exact products for each step.
- 1
Find and stop the source
Check pipes, bathrooms and the outside wall first. Painting over a wall that is still getting wet will not last.
- 2
Scrape and dry
Scrape off loose paint and putty down to the plaster and let the wall dry fully.
- 3
Damp-proof base coat
Apply a waterproof base coat made for inside walls, as the brand directs.
- 4
Waterproof putty
Level the wall with a putty that resists damp.
- 5
Washable, anti-fungal paint
Finish with two coats of an emulsion that resists fungus.
