Ronseal Thompsons Damp Seal

The Ronseal Thompsons Damp Seal in 750ml offers the ideal mid-size solution for medium-scale repairs and multi-room applications. This white finish damp seal provides high-performance sealing for damp patches, water stains and other household stains, perfectly sized for typical domestic projects and professional maintenance work. The micro-porous formulation allows trapped moisture to escape whilst permanently preventing stain reappearance. This versatile 750ml tin can be applied directly to damp surfaces without waiting, and the one coat formulation allows surfaces to be decorated in just 4 hours, keeping projects moving swiftly. With coverage up to 7m²/L depending on substrate porosity, this practical size balances coverage capacity with ease of handling. Allow 4 hours between each coat if a second application is needed, then leave for a further 4 hours before decorating.
