Thompson’s One Coat Water Seal provides effective and long-lasting waterproofing to any brickwork, pointing, stone, concrete or plaster. It creates a breathable waterproofing membrane that allows moisture vapour inside the substrate to evaporate whilst protecting against water penetration and damage.
