The Solution is Premium Protection

A Premium Wood Framing and Subfloor Sealer

Watson Seal™ Crawl Space Framing & Subfloor Sealer is the FIRST Non-Toxic, V.O.C. Free, Patent-Pending Polymer sealer, specifically designed to PROTECT your structural Framing and Subfloor System from moisture related damage. The sealer forms a tough, durable micro-film once dry that protects your crawl space framing and subfloor from excessive moisture absorption and stabilizes the existing moisture content levels in the wood to acceptable levels as well as reducing splits, warping and twist.

Watson Seal™ Crawl Space Framing & Subfloor Sealer works on all types of lumber including Engineered Joists, OSB, Plywood, Spruce, Pine, Oak and Fir. 

Our sealer dries to a satin finish and is  a semi-transparent orange. This allows installers, home owners and potential home buyers to easily recognize this home's floor framing system is PROTECTED by Watson Seal™ Crawl Space Framing & Subfloor Sealer. "It's GREEN, but it's ORANGE"

Resists Mold and Fungus

The sealer's micro-film resists mold and fungus associated with excessive moisture and the extreme conditions of the crawl space environment.
