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.  Our New & Improved NANO Penetrating Wood Sealer, deeply penetrates the surface of wood to protect and stabilize against water damage and decay.  Unlike many top-coat sealers that trap moisture below the surface, NANO creates a long-lasting, flexible, breathable barrier, that allows water vapor to escape & prevent damage.  NANO is warranted to prevent water intrusion for up to 10 years on horizontal & 6 years on vertical surfaces.

SEAL-ONCE® NANO Waterproofing Wood Sealer & Stain is ideal for use on unfinished interior and exterior wood surfaces. The clear, non-film forming formula allows the wood to age naturally without decay, morphing to a rich silver-gray over time. It can also be used as a wood stain, when mixed with a full range of semi-transparent tints to enhance the appearance & provide additional UV protection from sun rays.  When using SEAL-ONCE NANO as a pre-stain or sanding sealer, the clear formula allows for a smoother finish, more even color and easier application of water & solvent based stains or finishes. It also enhances the natural grain of the wood.
