NANO GUARD PREMIUM WOOD SEALER

SEAL-ONCE® NANO GUARD™ Premium Wood Sealer deeply penetrates the surface to protect and 

stabilize wood against weather and caustic conditions. 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.


Our clear, non-film forming NANO GUARD Premium Wood Sealer allows the wood to age naturally 

without decay, morphing to a rich silver-gray over time. We offer 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.
