Seal-Once Nano+Poly Wood Sealer and Waterproofer, Clear, 1 Gallon | With Polyurethane, Water-based, Low-VOC, Waterproofer & Stain, For Decks, Fences & Log Homes

WATER-BASED WOOD FINISH. Our sealant provides top-notch protection against wear and tear in high traffic areas. It's odorless and suitable for use on wood siding, log homes, swing sets, outdoor furniture, wooden deck and fence, and more

PENETRATING WOOD SEALANT. Unlike many sealers that only form a topcoat, our protector penetrates below the surface to create a long-lasting, water-resistant shield around the wood. It helps protect against the elements

ULTRA-LOW VOC FLOOR SEALER. Our premium gloss is ultra-low VOC and enhances the extended life of your exterior flooring. The sealant can be safely applied around your home, landscaping, vegetation, or over any water area

WATERPROOF SEALER. Ditch the oil-based sealers and choose a UV-stable coating option. Our fast-drying liquid creates a flexible, breathable barrier and provides a no-fuss, easy clean-up with soap and water, as it allows the wood to grey naturally

NON-TOXIC WOOD PROTECTION. Our user-friendly wood sealers and stains are an effective way to protect your lumber against water damage. When you use Seal-Once, you have the satisfaction of knowing our products will not harm pets, plants, or people
