5 GAL Multi-Surface Concentrate

5 Gallon Multi-Surface Concentrate with NANO deeply penetrates the surface to protect & stabilize wood, concrete & masonry against adverse weather & caustic conditions, including salt water spray. It uses proprietary nano-polymers to form a flexible, breathable barrier by coating the wood fibers and concrete pores, preventing water ingress. Multi-Surface Concentrate Waterproofing Sealer & Stain preserves the integrity of wood, concrete and masonry by inhibiting cracking, spalling, warping, cupping, rot, decay, mold, mildew & algae growth. It forms a pliable, breathable barrier that allows the substrate to expand & contract & water vapor to escape. It is non-film forming, non-yellowing and will not alter the natural color of wood, concrete or masonry. Multi-Surface Concentrate is diluted 1:1 with clean water to create the final, usable formula. It goes on milky white & dries clear. It allows wood to silver naturally over time, and can also be mixed with any of our 11 semi-transparent color tints for wood, to enhance the appearance of your project. Warranted to prevent long-standing water accumulation for up to 10 years on vertical & 6 years on horizontal surfaces. Not recommended for concrete driveways or garage floors.
