Preparation
Its important to make sure the cause of damp has been sorted before painting, otherwise it'll just come back.
Open doors & windows to make sure the room is well ventilated.
Remove any wallpaper and get rid of flaking paint with a damp cloth. Fill any cracks or holes, if needed.
You can apply this onto damp surfaces, just make sure they're not dripping wet.
Application
Give the tin a really good stir. Apply with a brush or roller, whichever you prefer. Apply the paint over the affected area, plus about 30cm around it.
Wait 4 hours before applying a second coat.
