      Concrete Joint and Spall Repair
      by ProREZ

      Rapid-setting, 100% solids structural repair materials formulated to restore and strengthen damaged concrete surfaces. Products like ProMender HF (Parts A and B) cure quickly—ready to grind in as little as 30 minutes—making them ideal for emergency spall, patching, and joint reconstruction in industrial or commercial settings. Their excellent tensile and compressive strength ensures long-term integrity under heavy traffic.

      This combined ProMENDER HF A (Resin) + B (Hardener) system contains a low-viscosity, pourable, “hard-and-fast” polyurethane repair material designed for rebuilding damaged control joints, repairing spalled concrete, and infilling cracks for structural repair. It mixes 1:1 by volume and cures rapidly and consistently from 45°F–85°F, with tack-free times dependent on film thickness and temperature and traffic readiness at ~45–60 minutes at 70°F. It is ultra-high solids with zero VOCs, self-priming, and provides tenacious bonding and good chemical resistance, with optional on-site pigmenting.
