Polyurethane high-wear-resistant flooring is a multi-component high-performance floor coating made of polyurethane resin as binder, with hardener, wear-resistant aggregate (such as quartz sand, emery sands) and functional additives. It chemically reacts to form a cross-linked cured coating that combines high hardness and flexibility to adhere tightly to the concrete surface to form a seamless, durable protective layer. Polyurethane coating can be used both outdoors and indoors floors.
