Ronseal Thompson Water Based Water Seal 2.5L 36285

The 2.5 litre size of Thompson's Water Seal offers excellent value for medium-sized exterior waterproofing projects, providing professional protection for walls, patios and other masonry surfaces. This mid-range format is popular with both trade professionals and homeowners undertaking substantial weatherproofing work. Utilising advanced hydrophobic technology, this invisible waterproofer penetrates deep into dry porous surfaces to form a breathable membrane. The formulation allows moisture vapour inside the substrate to evaporate whilst protecting against water penetration and damage. Unlike some waterproofers that only coat the surface, Thompson's Water Seal continues waterproofing even after initial beading is gone. The UV-resistant formula is long-lasting under heavy moisture conditions and helps prevent damage caused by freezing and thawing. When application instructions and coverage guidelines are followed, it provides effective water repellency for years.
