Stops damp showing through paint and wallpaper. Ronseal's Quick Drying Damp Seal is a unique basecoat that will permanently block damp stains and prevent them from damaging your top coat. The micro-porous formulation allows trapped moisture to evaporate from the surface preventing emulsion paint flaking or wallpaper peeling. It can also be applied directly to damp surfaces, leaving your walls and ceilings ready for decoration in as little as 24 hours.
