General description This Ronseal One Coat Damp Seal is designed to permanently block and seal damp stains on interior walls and ceilings. It can be applied directly onto damp surfaces, including damp patches, without extensive preparation. Once dry, it provides a protective barrier that prevents damp from affecting your paint or wallpaper while allowing trapped moisture to escape, reducing the risk of further damage and mold growth.
