Sherwin Williams/Thompson’s WaterSeal Clear Multi-Surface Waterproofer and Waterproofing Stains– Class Action Investigation

Sherwin Williams/Thompson’s WaterSeal Clear Multi-Surface Waterproofer and Waterproofing Stains– Class Action Investigation

Chimicles & Tikellis is investigating a proposed class action lawsuit against Sherwin Williams and its Thompson’s WaterSeal brand of waterproofing stains and coatings. Specifically, Thompson’s markets and sells a Clear Multi-Surface Waterproofer that is advertised as applying clear and capable of protecting wood against the elements, specifically water and rain. Consumers who purchase the Waterproofer find that, despite proper application, the Waterproofer applies and finishes cloudy rather than clear, is sticky and comes off onto shoes, smears, does not dry, and fails to properly waterproof surfaces. Thompson’s also recently altered the Waterproofer formula following an FTC decision requiring Thompson’s to reduce the product’s VOC levels; however Thompson’s has reportedly continued to sell the Waterproofer to consumers with the same labeling with which the product was sold prior to this decision.

C&T is also investigating Thompson’s Waterproofing stains. Despite proper application of these products, the stains begin flaking, chipping, or peeling shortly after application. These issues are obvious concerns to consumers as they can be costly to remedy and can result in damage to consumers’ underlying concrete or wood surfaces, such as patios or decks. Furthermore, consumers have been misled by Thompson’s failure to advertise its Clear Multi-Surface Waterproofer products with accurate labeling reflecting changes in the product, causing consumers to pay for products they may not have otherwise purchased.
