Ronseal One Coat Damp Seal

This 2.5 litre White Ronseal One Coat Damp Seal is ideal for larger projects and multiple rooms, providing extensive coverage for comprehensive damp treatment. Perfect for professional tradespeople and substantial renovation work, this generous format permanently blocks damp stains on walls and ceilings whilst allowing trapped moisture to escape. Apply directly onto damp surfaces using a brush or roller, ensuring you extend at least 30cm beyond any damp patches. Once the underlying cause of damp has been addressed and the surface prepared, you'll achieve touch dry results in 2 hours, with the seal ready to paint or wallpaper over after just 4 hours.
