SEAL-ONCE® EXOTIC with NANO GUARD™ Premium Wood Sealer deeply penetrates the surface to protect and stabilize exotic 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 EXOTIC with NANO GUARD™ allows rare wood species 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. SEAL-ONCE® EXOTIC is water-based.
