How does SEAL-ONCE NANO GUARD work?

SEAL-ONCE® NANO GUARDTM deeply penetrates the wood or concrete surface by utilizing eco-friendly nano-polymers to form a flexible breathable barrier that prevents damage caused by water ingress. Its nano-polymers are not visible to the naked eye and are approximately one-millionth the length of a millimeter. As a result, these particles are able to deeply penetrate the surface, providing superior protection from the inside-out.
