Thompson's® Water Seal®

Thompson's® Water Seal® - Sealers and Finishes

In the early 1920s, polymer chemist Edward Addis Thompson developed a product that protected buildings from exterior water damage. His discovery became known as Thompson's® Water Seal® 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® Water Seal® Clear Multi-Surface Waterproofer to consumers in 1982.

The deck protection category was born.

Thompson's® Water Seal® Clear Multi-Surface Waterproofer is just one product in an extended brand line that includes wood protection, concrete care, and our newest addition, Thompsons® Water Seal® Advanced Waterproofers — a breakthrough formula providing the ultimate in advanced waterproofing power.

The Thompson's Company has earned a well-deserved reputation as a leader in identifying industry trends and emerging technologies.

We are the consumer research innovators. And we ensure the effectiveness of all of our products. The Thompson's Company will continue to respond to consumer's needs through the continued development of innovative products.
