Ronseal Thompsons Damp Seal

The Ronseal Thompsons Damp Seal in 250ml is the perfect compact solution for smaller repair jobs and spot treatments. This white finish damp seal provides high-performance sealing for localised damp patches, water stains and other household stains, making it ideal for quick fixes around the home or on-site. The micro-porous formulation allows trapped moisture to escape whilst permanently preventing stain reappearance. This handy 250ml tin can be applied directly to damp surfaces without waiting for them to dry, and the one coat formulation allows you to decorate over the surface in just 4 hours. With coverage up to 7m²/L depending on substrate porosity, this smaller size offers excellent value for targeted applications. Allow 4 hours between each coat if a second application is required, then leave for a further 4 hours before decorating.
