DRYLOK® Masonry Waterproofer has many solutions to waterproof and just as important - beautify your space.
In the early 1920’s, polymer chemist Edward Addis Thompson developed a formula that protected buildings from exterior water damage. His discovery became known as Thompson's® WaterSeal® Clear Multi-Surface Waterproofer and initially was used by architectural and construction firms for concrete applications. After recognizing the fast-growing deck-building trend, The Thompson's Company expanded distribution of Thompson's® WaterSeal® Clear Multi-Surface Waterproofer to consumers in 1982. The deck protection category was born. Thompson's® WaterSeal® Waterproofer Plus Clear Wood Protector is just one product in an extended brand line that includes specialized cleaners, waterproofing products for wood, fabric and concrete surfaces, and a complete line of Waterproofing Stains that offer wood stain and sealer all in one.
