HENRY 1172 is a professional-grade, acrylic-urethane hybrid adhesive designed for permanent interior wood flooring installations. Use for engineered wood plank flooring up to 3/4 in. thick and 12 in. wide, and cork sheet underlayment. This premium formula delivers an exceptional initial grab that keeps solid and engineered wood planks firmly in place during layout, preventing shifting and minimizing hollow spots. Engineered with flexible elongation characteristics, it cures into a tough yet resilient bond that moves naturally with the wood's seasonal expansion and contraction. Beyond its superior bonding strength, this adhesive offers enhanced moisture and concrete alkali resistance to protect flooring from warping, cupping, and delamination. It features a solvent-free, low-odor, and low-VOC formulation with built-in antimicrobial protection, making it safe for indoor air quality and contributing toward LEED points. It is compatible with porous concrete, underlayment grade plywood, OSB, and radiant heated subfloors.
