PPC OS Polyurethane Membrane is a seamless, monolithic, solvent-free dual-component polyurethane waterproofing system engineered for heavy-duty traffic-grade wear surfaces. With rapid gelation and a 9-minute pot life, it can be applied at up to 200 mils in a single pass across interior and exterior concrete, metal, plywood, or as an asphalt underlayment. Its resilience against environmental humidity and thermal fluctuations ensures consistent performance down to 20°F. Available in pre-textured and smooth finishes, it delivers excellent weathering, high flexibility, dirt resistance, and meets all VOC requirements — with no protection board needed under pavers.
