KEMPEROL® AC Speed FR is a quick-curing, cold liquid-applied Polymethyl Methacrylate (PMMA) waterproofing resin that can allow same-day application. The membrane is fully reinforced with a needle-punched polyester fleece that provides exceptional durability for exposed or buried roofing & waterproofing applications. The resin is available in two standard colors, gray or a highly reflective white with an SRI of 108.
For roofing applications, KEMPEROL® AC Speed FR system can be applied exposed, direct-to-deck, over an insulated assembly, or recover an existing membrane. The self-flashing membrane is ideal for inverted roof applications as there are no seams or termination bars used.
When used for waterproofing, the membrane can be covered with tile, paver, pavement, growing media and other types of approved overburden. Optional KEMPERDUR® AC Traffic Coating allows for additional surfacing of balconies, terraces, walkways and parking decks with the quick-cure performance.
