PPC WC Membrane Sealant is a rapid-setting, moisture-reactive single-component elastic membrane engineered for high-tier interior and exterior sealing applications. Functioning simultaneously as a potent adhesive and protective coating, it is optimized for roofing systems, subsurface waterproofing, expansion joint sealing, and concrete remediation. Self-priming on most construction surfaces and odor-neutral for use in confined spaces, it can be applied directly from the container at any thickness in a single pass. With 100% solids, a service temperature range of -25°F to 200°F, and certifications including ASTM C-920, it delivers durable, climate-resistant performance across diverse substrates.
