This 250ml White Ronseal One Coat Damp Seal is the perfect size for treating smaller damp patches and spot repairs around the home. Ideal for targeting isolated problem areas, this compact format permanently blocks damp stains on walls and ceilings whilst allowing trapped moisture to escape. You can apply it directly onto damp surfaces, making it convenient for quick repairs. Simply ensure the cause of damp has been fixed, prepare the surface by removing wallpaper and loose paint, then apply with a brush or roller, extending at least 30cm beyond the damp patch. The seal is touch dry in 2 hours and ready to paint or wallpaper over after 4 hours.
