LumberKote™

The Complete Crawl Space Framing & Subfloor Sealer

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 occurring, saving homeowners the trouble and expense down the road.

LumberKote™ works on ALL structural framing including the floor framing system, wall and attic framing including interior and exterior roof decking and 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™ delivers an affordable and unmatched level of protection and peace-of-mind in re-active damage repair, pro-active damage prevention, stage or budgetary situations. Talk to your Authorized Watson Seal LumberKote™ Certified Dealer about what's best for you and your home's situation.

LumberKote™ protects the entire floor framing system including joists, subflooring, girder beams, sill plate and rim band directly and controls automatically the correct moisture balance for wood to achieve strength, resist environmental issues and control warp, deflection, deterioration and rot of joists and subfloor materials that make up your home's structural floor and wall framing systems.

Using long-chain polymer technology, the permeation of moisture and organic food source (wood) is protected by a high adhesion coating that was designed over 20+ years ago, enhanced and strengthened to now be Commercial Grade. Our coating has been applied by tens of thousands of customers, reviewed by chemists, independently tested for factual content, exceeds all ASTM guidelines and requirements and real-world extreme tested during the early stages of its existence. Reviewed by insurance companies for coverage, scientists for non-toxicity, leaching, mold growth potential, absorption rates for moisture as well as adhesion, LumberKote™ stands alone as a proven, modern method of protecting your home.

LumberKote™ can be installed without the need for removing pre-existing mold and fungus unless those conditions are deemed heavy or extreme. Using LumberKleen™ is the BEST way to effectively clean and oxidize organic material before installing LumberKote™, ensuring the perfect install every time.
