FGS HARDENER PLUS™ 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. When used in conjunction with the patented FGS PERMASHINE® FLOOR POLISHING PROCESS, FGS HARDENER PLUS penetrates diamond ground and polished concrete wear surfaces to harden, seal, densify, and waterproof them. Polished concrete floors treated with FGS HARDENER PLUS 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. FGS HARDENER PLUS is a water-based, VOC-compliant, odorless and environmentally safe component of this process.
