SEAL-ONCE® Multi-Surface Concentrate deeply penetrates the surface to protect and stabilize wood, concrete and masonry against water damage and decay. It uses proprietary nanotechnology to create a long-lasting, flexible, breathable barrier to provide protection from the inside out.
Multi-Surface Concentrate is diluted 1:1 with clean water to create the final, usable formula. It protects against warping, cupping, cracking, spalling, rot and decay. It also prevents mold, mildew and fungi growth.
Multi-Surface Concentrate is non-yellowing and will not alter the original appearance of the wood, concrete or masonry. It allows wood to silver naturally over time, and can also be mixed with any of our available Semi-Transparent Tints for Wood to enhance the appearance of your project.
