SEAL-ONCE® NANO+POLYTM Premium Wood Sealer combines our proprietary nanotechnology formula with the strength of polyurethane to provide 360° of protection. It creates a durable finish that allows wood to expand and contract while protecting against wear and tear.

NANO+POLYTM penetrates to form a long-lasting water resistant shield around the wood fibers, preventing wood rot, decay, mold and mildew. It also stabilizes wood, eliminating warping and cupping.

NANO+POLYTM can be used to preserve old or new wood, extending its natural life. It is UV stable and it has UV blockers to prevent the natural color of the wood from fading. It is also compatible with our Semi-Transparent Tints.

NANO+POLYTM is water based, non-toxic, has ultra-low VOCs and no odor. It can be applied around landscaping, vegetation or over water without causing damage.

  • Surfaces that have been treated with SEAL-ONCE NANO + POLY Premium Wood Sealer can be cleaned using a mixture of 1-gallon warm water, 14 oz. bleach, and 1 oz. of Dawn® dish detergent. Apply this cleaning solution with a sprayer and allow to sit for 20 to 30 minutes on the wood surface before rinsing with water using a garden hose with a nozzle.
  • This cleaning solution can be used to remove airborne mold and mildew stains, dirt and grime from the wood surface. NANO + POLY will prevent and resist any water, mold and mildew penetration. Do not use oxidizers, corrosives, or strippers on surfaces that have been treated with NANO + POLY.
  • Surfaces can be recoated with NANO + POLY at any time. NANO + POLY may need to be reapplied for fading tint color, surface damage, in heavily worn or high traffic areas, or in places where the surface may have undergone noticeable changes.
  • Before reapplying NANO + POLY, clean the surface using the recommended cleaning solution above. Apply NANO + POLY according to package instructions. When reapplying in small areas, lightly overlap onto areas previously treated with NANO + POLY.
