## Description

Seal-Once Nano+Poly Penetrating Wood Sealant with Polyurethane is safe for the user and far more protective against water and UV rays than other competitors. Our polyurethane sealant will not damage pets, plants, people, or the color of your surface. It has a flexible, breathable barrier and is water and abrasion resistant. The leak proof deck sealer (you can't call it deck sealer after explaining all its previous uses) has no chemicals like oil and solvent based sealants, allowing you to safely apply it around homes, landscaping, marine life, livestock, and vegetation. This 1 gallon comes in a clear matte finish that won't alter stains from the original look of your deck, fence, or log house. Nano+Poly Premium Wood Sealer combines our proprietary nanotechnology formula with the strength of polyurethane to provide 360 degrees of exterior protection to extend the natural life of the wood. Use soap and water for easy cleaning. Seal-Once is guaranteed to prevent long-lasting water build-up up to 10 years on vertical surfaces and 6 years on horizontal surfaces.

## Features

- WATER BASED PU WOOD FINISH - Our sealant provides first-class protection against wear in high traffic areas. It is odorless and ideal for use on wood siding, log houses, swings, outdoor furniture, wood decking and fence, and more.
- WOOD SEALER - Unlike many sealants that only form a top coat, our protector penetrates under the surface to create a durable, water-resistant shield around the wood. Helps resist wood damage, deterioration and protects against the elements.
- FLOOR SEALER APPLICATOR - Our premium gloss is ultra low VOC and ideal for improving the extended life of your outdoor floor. Sealant can be safely applied around your home, landscaping, greenery, or over any water area.
- WATERPROOF SEALANT - Get rid of oil-based sealants and choose a UV resistant coating option. Our quick drying liquid creates a flexible, breathable barrier and provides easy cleaning with soap and water as it allows the wood to turn gray naturally.
- SEAL-ONCE: Our easy-to-use wood and stain sealers are an effective way to protect your wood or concrete against water damage. When you use Seal-Once, you have the satisfaction of knowing that our products will not harm pets, plants or people.
