WPA 3400

WPA 3400 is a two-component, 100% solids, rapid curing, spray applied, hybrid polyurea, elastomeric waterproofing membrane. WPA 3400 is comprised of a polyether polyol, amine chain extender and MDI-based isocyanate. WPA 3400 rapidly cures to form a high-performance seamless, tough, durable, elastomeric waterproofing membrane, with good crack-bridging properties. WPA 3400 has excellent adhesion to most suitably primed building substrates and is suitable for above and below-ground applications.
