Watson Seal® LumberKote™ is the FIRST Non-Toxic, V.O.C. Free, Crawl Space Framing & Subfloor Polymer Sealer specifically designed to PROTECT your structural Framing and Subfloor System from excessive moisture absorption and rapid moisture uptake that deteriorates and rots lumber and accelerates the growth and damage by wood destroying mold and fungus. The sealer forms a tough, durable micro-film once dry that protects your crawl space framing and subfloor in one step. LumberKote's™ micro-film resists mold and fungus (ASTM D3273) and is USDA and FDA compliant.

Our long-chain polymer technology utilizes controlled desiccation osmosis to immediately begin drying out lumber and stabilizing the lumber's moisture content to acceptable levels when situations of repairs are required like sagging floors, hardwood cupping, etc. LumberKote™ works to prevent these costly issues from occuring in newer constructed homes, saving homeowners the trouble and expense down the road.

LumberKote™ works on all types of lumber including Engineered Joists, OSB, Plywood, Spruce, Pine, Oak and Fir. It dries to durable 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 Watson Seal® PROTECTED.

LumberKote™ is the best solution to ensuring the perfect "bullet-proof" crawl space encapsulation or can be used alone and delivers an unmatched level of protection and peace-of-mind in re-active damage repair, pro-active damage prevention, stage or budgetary situations.
