SEAL-ONCE NANO+POLY Premium Wood Sealer in Mahogany Color combines our proprietary nanotechnology formula with the strength of polyurethane to provide 360° of protection. The NANO creates a durable finish that allows wood to expand & contract, while the POLY adds surface protection against wear & tear in high traffic areas. Unlike many 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, mold & 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. When used as a wood stain, the Nano+Poly Standard Colors provides added UV protection. 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 & 6 years on horizontal surfaces.
