Thompsons Waterseal 5L

Thompson’s Water seal is a New improved transparent, water based waterproofer that is designed to penetrate dry, porous, exterior substrates to prevent access of moisture.
Water seal is a high performance transparent water repellant that penertrates exterior brickwork, wood and cementatious substrates to form a long lasting barrier against rain damage.
Its formular contains a silicone micro-emulsion which prevents water penertration and subsequent problems caused by “freeze-thawing” which can break-up the substarte.
Thompsons Water seal has been reformulated to last longer than the standard waterproofers, continuing to repel water and help prevent water damage long after other products have begun to fail.
Penetrating deep into the surface it repels more water for longer than standard clear waterproofers and can provide effective water repelancy for years, assuming application instructions and coverage guidlines are adhered to.
It is long lasting, even under heavy moisture conditions, and is not destroyed by UV light.
