SEAL HARD is a proprietary, chemical hardening solution that is formulated to increase the wear resistance and surface strength of concrete floors that have been mechanically ground, smoothed, and polished. SEAL HARD penetrates diamond ground and polished concrete wear surfaces to harden, seal, densify, and makes them impervious to water. Polished concrete floors treated with SEAL HARD last longer than conventional concrete floors, cost less to maintain, reflect light better, hold a shine longer, are safe to use, and are guaranteed to resist dusting for a minimum of ten years. SEAL HARD is a water-based, low VOC, odorless and environmentally safe component of this process.
