Thompsons One Coat Concrete Seal is a high-performance, durable sealer for concrete and masonry. With its unique one-coat formulation, it provides a long-lasting protective barrier against water damage, resisting the ingress of water without blocking the release of moisture vapour from the substrate. This 5L can cover up to 40m² per litre depending on the porosity of the surface. Suitable for both interior and exterior use, it dries to a clear finish that enhances the natural appearance of your concrete.
