SEAL-ONCE® has been leading the innovation in the use of nanotechnology to create long-lasting, Eco-friendly wood sealers & tinted wood stains since 2005. MARINE Premium wood sealer and dock stain is specifically formulated to provide the highest level of protection for wood structures, situated near open water. Wood used on boat docks, decks, and retaining walls near rivers, lakes, ponds or the ocean is subjected to near constant moisture. MARINE provides the highest level of protection in those environments. It is a great investment to extend the useful life of wood subjected to these harsh marine conditions, is non-hazardous to aquatic life.
SEAL-ONCE® MARINE Premium Waterproofing Wood Sealer & Stain is designed to protect & stabilize marine wood against water damage, salt water spray & decay. Unlike many top-coat sealers on the market today, it penetrates wood below the surface, coating the wood fibers at the cellular level, which creates a long-lasting, flexible, breathable barrier. It provides long-lasting protection from the inside out.
Clear formula allows wood to age naturally without decay, morphing to a rich silver-gray over time. Seal-Once Marine, when tinted as a wood stain, gives added protection from decay. Prevents long-standing water accumulation for up to 10 years on vertical & up to 6 years on horizontal surfaces.
