## Description

SEAL-ONCE MARINE Premium Wood Sealer protects and stabilizes wood against water damage and decay. It uses proprietary nanotechnology to penetrate, coating the wood fibers at the cellular level. The advanced technology of MARINE allows it to form a superior barrier below the surface, protecting from the inside out.MARINE allows wood to age naturally without decay, and can be used to preserve old or new wood, extending its natural life. It is non-film forming and will not alter the natural beauty of the wood. It can be applied around or over open water, without harming marine life. MARINE preserves the integrity of the wood by inhibiting warping, cupping, rot, mold, mildew and algae growth. MARINE forms a flexible breathable barrier that allows the wood to expand and contract, and for water vapor to escape. MARINE goes on milky white and dries clear. It is also available in semi-transparent tints. Recommended Applications• Decks • Docks • Railings • Piers • Retaining walls • Outdoor furniture. Available in 11 semi-transparent color tints. Choose from Battleship Gray, Black, Bronze Cedar, Brown, Cape Cod Gray, Cedar, Light Brown, Mahogany, Natural, Redwood & Shale Gray. Typical sealers form a barrier on the surface, trapping moisture below the surface. As water evaporates, it causes the surface coating to crack & peel, leaving a surface that requires continued maintenance. SEAL-ONCE protects against water damage, using proprietary nanotechnology that penetrates deep into the wood and bonds to the wood fibers and cells at a microscopic level. SEAL-ONCE protects from the inside out to provide unparalleled protection & stability for wood. The flexible, breathable barrier created by SEAL-ONCE, allows water vapor to escape while preventing damage caused by water intrusion.
