Stop damp stains from ruining your decor with Polycell One Coat Damp Seal. This 1-litre tin contains a high-performance anti-damp paint designed to seal and block moisture on interior walls and ceilings. Standard emulsion paints simply cover the stain temporarily, but this advanced formula creates a permanent barrier that prevents water marks from bleeding through and ruining your new finish. It is the ultimate problem solver for households dealing with isolated damp patches caused by penetrating moisture or condensation.

The "One Coat" technology is a major time-saver, providing a thick, opaque seal in a single application. It dries to a neutral matt white finish, which serves as an excellent primer for your final decoration. You can paint over it with any standard emulsion or hang wallpaper directly onto the treated surface once dry. Beyond aesthetics, this product effectively stops paint from flaking and wallpaper from lifting, addressing the physical damage damp can cause to your decor. Ideally suited for use on plaster, brick, and stone, it is versatile enough for any room in the house. With a drying time of roughly 4 hours, it allows you to prep and paint in the same day.
