ProMender HF

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.
