Yes. TRICOPOLYMER is the only wood sealer independently verified by Underwriters Laboratory to be non-toxic and non-leaching. Once fully cured, it does not migrate into soil or plant roots. It is USDA and FDA reviewed, contains no Prop 65-listed ingredients, and has been in use on vegetable garden beds for over 29 years without any reports of contamination.

No. TRICOPOLYMER is completely VOC-free — it contains zero volatile organic compounds. There is no chemical odor during application and no off-gassing during or after curing. It is safe to apply in enclosed spaces, crawl spaces, and occupied buildings. The NFPA/HMIS health rating is 0 for the standard formula.

4 to 26 years, depending on the application and level of exposure. High-exposure applications such as outdoor decking, marine structures, or surfaces under constant weather contact typically last 4–7 years between recoats. Moderate-exposure surfaces like fences and siding commonly see 10–15 years. Low-exposure applications such as interior structural wood, crawl spaces, and sheltered structures can last up to 26 years. Two coats are recommended for maximum service life.

Yes, when used properly and fully cured. TRICOPOLYMER has been tested on a wide range of species including dogs, cats, horses, poultry, reptiles, and marine animals. It is safe for use in kennels, stalls, barns, chicken coops, birdhouses, reptile enclosures, and zoo habitats. It has a 29-year history of use in animal environments with no adverse effects reported.

TRICOPOLYMER works on all species of softwoods and hardwoods, green or dry — including pressure-treated lumber, cedar, and high-oil-content species. Cedar-Seal is specifically formulated for cedar and other high-oil woods. It is also effective on metal, steel, aluminum, and clay surfaces.

Coverage varies by application method: approximately 150 sq ft per gallon by brush, 250 sq ft by roller, 300–500 sq ft by paint pad, and 300–1,100 sq ft by sprayer depending on pressure and technique. Two coats are standard for most applications.

Yes. TRICOPOLYMER is compatible with all water-based stains and paints. It can be applied after a water-based stain or used as an economical primer before painting with any water-based paint product. Its adhesive performance exceeds most primers at a lower cost per square foot.

Yes. CrawlSpace-Seal is a patented spray-applied formula (US Patent No. 11,655,389) specifically engineered for the wood surfaces of crawl spaces. It is fast-drying, moisture-resistant, and designed to protect structural lumber in the confined, humid conditions of a crawl space environment. It is available in single pails, pallets, and totes for contractor-scale projects.
