Ronseal Thompsons Water Seal

Ronseal Thompson's Water Seal utilises advanced hydrophobic technology to deliver invisible, long-lasting protection against water damage on exterior masonry surfaces. Available in a range of sizes to suit projects of all scales, this professional-grade waterproofer is ideal for protecting brick, concrete and stone from moisture penetration.

The penetrating formulation travels deep into dry porous surfaces to form a breathable membrane that allows moisture vapour inside the substrate to evaporate whilst protecting against water ingress. Unlike surface-only waterproofers, Thompson's Water Seal continues to provide effective protection even after the initial beading is gone, as the treatment penetrates into the material itself.

The formulation is UV-resistant and long-lasting even under heavy moisture conditions, helping to prevent damage caused by freezing and thawing. For exterior use only.
