MULTI-SURFACE CONCENTRATE WITH NANO GUARD
SEAL-ONCE® Multi-Surface Concentrate with NANO GUARD™ deeply penetrates the surface to
protect and stabilize wood, concrete and masonry against weather and caustic conditions. It uses
proprietary nano-polymers to create a long-lasting flexible breathable barrier to provide protection
from the inside out.
Multi-Surface Concentrate with NANO GUARD will not alter the original appearance of the wood,
concrete or masonry, and it allows wood to age naturally over time. It can also be mixed with any of
our available Semi-Transparent Tints to enhance the appearance of your project.
