Ronseal One Coat Damp Seal

This 500ml White Ronseal One Coat Damp Seal offers excellent versatility for medium-sized projects and multiple smaller repairs throughout your property. A practical choice for treating several damp patches or covering moderate areas, this format permanently blocks damp stains on walls and ceilings whilst allowing trapped moisture to escape. Once you've addressed the cause of damp and prepared the surface by removing wallpaper and loose paint, simply apply with a brush or roller, extending at least 30cm beyond the damp area. The seal is touch dry in 2 hours and ready to paint or wallpaper over after 4 hours, making it convenient for same-day decorating projects.
