Experience the next evolution in wood protection. Seal-Once NANO+POLY™ combines proprietary nanotechnology with the durability of a polyurethane wood sealer to provide 360° of protection. Unlike traditional topical coatings that sit on the surface and peel over time, this hybrid formula penetrates deep into the wood fibers to create a structural water-resistant shield while the polyurethane reinforces the surface against abrasion and foot traffic.

Designed for high-performance in demanding environments, Seal-Once Nano Poly creates a flexible, breathable barrier. This allows moisture vapor to escape from inside the wood, preventing the rot, mold, and decay that often occurs under rigid film-forming sealers. Whether you are protecting a high-traffic deck, log home, or siding, this eco-friendly formula stabilizes the wood to eliminate warping and cupping while ensuring safety for pets, plants, and marine life.

PRODUCT DETAILS

Unlike many polyurethane wood sealers that only form a top-coat, NANO+POLY penetrates below the surface to form a long-lasting, water-resistant shield around the wood fibers at the cellular level.  This penetrating protection from water intrusion helps resist wood rot, decay & mildew. It also stabilizes wood, eliminating warping & cupping.   It is a great investment to preserve old or new wood & extend its natural life for years.

NANO+POLY has no toxic chemicals like many oil & solvent based sealers,  so it can be applied around your home, landscaping, vegetation or over water safely.  Warranted to prevent long-standing water accumulation for up to 10 years on vertical & up to 6 years on horizontal surfaces.
