SEAL-ONCE Nano+Poly Penetrating Wood Sealer with Polyurethane - 1 Quart. Water-Based, Low-VOC, waterproofer & Stain for Decks, Fences & Log Homes.

SEAL-ONCE NANO+POLY is the safe way to protect & enhance your investment & extend the natural life of wood. This premium water-based, wood protector combines proprietary nanotechnology with the strength of polyurethane to provide 360° of protection. Protects up to 10 years on vertical surfaces & 6 years on horizontal with no toxic chemicals, making it easy to apply and safe for people, pets & plants. Unlike many brands that only form a top-coat, NANO+POLY penetrates wood to form a long-lasting water-resistant shield around the wood fibers, preventing rot, decay, mold & mildew. It also stabilizes wood, eliminating warping and cupping. With the added POLY, NANO+POLY also creates a durable surface coating that protects against wear and tear, UV fading and water damage. NANO+POLY is a water-based, eco-safe sealer that goes on milky white and dries clear. It creates a UV-stable coating that preserves the natural color of the wood and resists weathering and decay. It is also available in 11 semi-transparent color tints that provide added UV protection. Battleship Gray, Black, Bronze Cedar, Brown, Cape Cod Gray, Cedar, Light Brown, Mahogany, Natural, Redwood & Shale Gray. Recommended Applications • Decks • Railings • Wood siding • Log homes • Thermally modified wood • Docks • Piers • Fences • Exposed beams • Outdoor furniture • Planters • Play structures • Cedar shingles. 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.
