Find the Right SEAL-ONCE Product for Your Project

SEAL-ONCE® NANO+POLYTM Premium Wood Sealer combines our proprietary nanotechnology formula with the strength of polyurethane to provide 360° of protection. Now available in Clear and Ready Mixed Colors! 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+POLYTM 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+POLYTM 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.

*Actual stain colors may vary from on-screen and printer representations.*

Product Details

  • All surfaces should be cleaned before sealing for best penetration and performance.
  • Wet the surface.
  • Clean the surface with a solution of 1/2 cup Seal-Once Wood Cleaner to 1 gallon of water. Apply this solution to the wood with a garden pump sprayer.
  • Let the solution sit for 15-20 minutes. Do not let the cleaner dry.  Keep it wet.
  • Power wash the cleaning solution from the wood. To prevent damaging the wood do not exceed 500psi.  Keep the nozzle 1-2 feet away from the surface.
  • Rinse thoroughly.
  • Let the surface dry 1-2 dry days before application of Seal-Once.
  • Test absorbency after cleaning by sprinkling water on surface. If the water does not readily penetrate the surface, stripping will be necessary to remove old coatings.
  • Do not use if air or surface temperature is below 50°F/10°C or above 95°F/35°C.
  • Do not apply in rain or when rain is imminent. For all stains (including Ready-Mixed), intermix gallons and stir to ensure color consistency.

  • Apply first coat with a synthetic brush; pump-up garden sprayer; air-assisted and/or airless sprayer. Use 15-17 tip and medium to coarse spray pattern. When spraying, always back brush for best results.
