About this product
Rustins Damp Seal is a fast-drying interior paint for treating damp walls and ceilings, in a 500ml size suited to small to medium projects. It can be applied directly to damp surfaces, permanently covering water stains and household marks, and dries in around 2 hours ready for recoating. The formula does not cure damp but allows trapped moisture to escape gradually, which helps prevent paint flaking or wallpaper peeling that can occur with ordinary paints. Once dry, the sealed surface can be finished with gloss or emulsion paint, or wallpapered over directly. It is a white paint intended for interior walls and ceilings.
