PU‑Crete 99 is a three‑component, 99% solids, fully aliphatic, UV‑stable polyurethane flooring and leveling system. It combines a polyol resin (Part A), an aliphatic isocyanate curing agent (Part B), and a finely graded LM ceramic‑aggregate blend (Part C) to deliver a seamless, high‑build surface that hides substrate imperfections with minimal preparation. The ceramic‑aggregate overcomes exotherm issues common in cementitious systems, allowing safer, cooler cures.
