The Ronseal One Coat Damp Seal permanently blocks damp stains on walls and ceilings. You can even put it onto damp walls. It lets trapped moisture escape without causing anymore damage. When it's dry you can paint or wallpaper over it. BEFORE YOU START Make sure the cause of damp has been fixed. Open your doors and windows for ventilation and put down dustsheets to protect anything you don't want to get paint on. Preparation: Remove any wallpaper with a scraper and sand off any loose or flaking paint. Make sure the area you are painting is clean, if you've got mould, get rid of it with our 3-in-1 Mould Killer. You can paint onto damp surfaces, just make sure they're not dripping wet. USING YOUR DAMP SEAL Give the paint a really good stir, then use a roller or brush to put it on. If you're covering a small damp patch, make sure you are painting at least 30cm around the area. It'll be touch dry in 2 hours. After 4 hours it'll be ready to paint or wallpaper over. If the area is prone to mould, you can paint over it with our 6 Year Anti-Mould Paint.
