What is the difference between SEAL-ONCE NANO and NANO+POLY?

SEAL-ONCE NANO is a non-film forming, deep-penetrating, water based formula that creates a flexible, breathable barrier to protect wood against damage caused by water ingress. It is ideal for vertical surfaces and areas that will not be subjected to a high level of wear and tear.

SEAL-ONCE NANO+POLY combines our proprietary nanotechnology formula with the strength of polyurethane to provide 360° of protection for wood, concrete and masonry. It is ideal for high traffic applications such as decks and patios.
