About Us

Our Brand Heritage

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.

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 our products. The Thompson's Company will continue to respond to consumers’ needs through the continued development of innovative products.
