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.

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.

Clean your equipment with white spirit.
