SEAL-ONCE protects against water damage, using proprietary nanotechnology that penetrates deep into the wood and bonds to the wood fibers and cells at a microscopic level. This forms a long-lasting shield that protects from the inside out.
In concrete and masonry, SEAL-ONCE penetrates deep within the capillaries of the substrate, creating a flexible, breathable barrier that prevents water from causing damage, and allows water vapor to escape.
SEAL-ONCE® isn’t just good for the protection of your wood, concrete or masonry project; it’s good for the environment.
SEAL-ONCE offers an eco-friendly, and effective, way to protect your wood or concrete against water damage. The proprietary technology of SEAL-ONCE prevents water, mold and decay below the surface, protecting from the inside out.
When you use SEAL-ONCE, you have the satisfaction of knowing our products will not harm pets, plants, people, livestock or marine life.
