Seal-Once Nano Guard Premium Wood Sealer is one of the only green stain/sealers on the market formulated for exterior/interior. Seal-Once seals and protect for up to 10 years!

Seal-Once Nano Guard Premium Wood Sealer deeply penetrates the surface to protect and stabilize wood against weather. This formula uses proprietary nano-polymers to create a long-lasting flexible breathable barrier by coating the wood fibers at the cellular level to provide protection from the inside out. The flexible breathable barrier created by SEAL-ONCE NANO GUARD allows water vapor to escape while preventing damage caused by water intrusion, such as rot, decay, mold and mildew growth, cracking, splitting and spalling.

Typical sealers form a barrier on the surface of the wood trapping water below the surface. As the water evaporates, it causes the surface coating and the substrate to crack and peel, leaving a damaged surface that requires continued maintenance and is susceptible to water intrusion. SEAL-ONCE NANO GUARD prevents this from happening by protecting from the inside out.

This non-film forming NANO GUARD Premium Wood Sealer offers a full range of Semi-Transparent Tints that can be added to the clear formula. These tints operate as UV blockers to prevent the wood from graying while enhancing the natural grain and texture.

This wood stain is great for log homes, log siding, decks, fences, outdoor furniture, and shake roofs.
