GAF Liquid Membrane & Coating TOPCOAT® FireShield® MB

Description FireShield® MB Elastomeric Roofing Membrane is a water-based, 100% acrylic that cures to form a seamless rubber membrane. FireShield® MB, with its patent-pending technology will maintain, or may improve UL rating on select roofing systems or assemblies.** It is designed to enhance your roof system’s protective performance by providing unique fire extinguishing properties. Special fire resistant ingredients in the product react with heat and fire causing a chemical reaction to occur. A non-combustible carbon char layer is formed that retards flame propagation by reducing available oxygen. FireShield® MB is listed by the Cool Roof Rating CouncilSM for solar reflectance and thermal emittance. Its high reflectivity and thermal emittance will help to reduce heat gain to preserve the roof substrate, lower interior temperatures and reduce cooling costs. Sprayable, seamless FireShield® systems install fast, without the tear-off, staging, and disposal associated with traditional systems. Comprehensive warranties are available. Uses FireShield® MB Elastomeric Roofing Membrane is designed to protect new BUR and modified bitumen roofs as well as protect and restore metal as a primer Hypalon®, wood, and concrete. FireShield® MB is formulated to provide maximum fire protection, increase a roof’s reflectivity and to protect the roof substrate from harmful ultraviolet rays. It is highly flexible to accommodate temperature-related expansion and contraction of the roof system, a leading cause of roof system failure. Substrate shall not pond water for a period longer than 48 hours. Surface must be free of ponding water, ice, snow and debris prior to application. Do not apply at temperatures below 42°F. Substrate temperatures must be below 120°F when applying product.
