THOMPSONS DAMPSEAL 2.5l 32010 is a specialist paint designed to block damp stains on interior walls and ceilings. Supplied in a 2.5 litre container, it is often used during refurbishment projects where surfaces show water marks, tide lines, or other evidence of moisture ingress, providing a practical solution before further decoration.
Builders typically apply the product as a base coat with a brush, roller, or spray, making it adaptable to various site conditions and surface textures. It helps prevent existing stains from coming through new paint or wallpaper, supporting a cleaner and more consistent final appearance across treated areas.
