The Ronseal One Coat Damp Seal is your ultimate solution for permanently blocking damp stains on walls and ceilings. This innovative product can be applied directly onto damp walls, allowing trapped moisture to escape without causing further damage. Once dry, you can seamlessly paint or wallpaper over it, ensuring a flawless finish for your interior spaces.

Before you start, it's crucial to ensure that the source of the damp has been fixed. For optimal results, open your doors and windows to provide adequate ventilation and lay down dustsheets to protect any surfaces you don't want to get paint on. Proper preparation is key: remove any existing wallpaper with a scraper and sand off any loose or flaking paint. Make sure the area you are painting is clean, and if mould is present, eliminate it using our 3-in-1 Mould Killer.

The Ronseal One Coat Damp Seal is suitable for all indoor walls and ceilings, whether bare or previously painted. Cleaning up is a breeze—simply wash your brushes or rollers in warm, soapy water. With a coverage of 5m² per litre, this product is both efficient and effective.
