The 5 litre size of Thompson's Water Seal is the professional choice for larger exterior waterproofing projects, offering exceptional coverage and value for substantial masonry protection work. This generous format is ideal for contractors and property maintenance professionals tackling extensive walls, driveways, patios and other large porous surfaces. 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.
