FireShield® MB Roof Coating


Description

United Coatings FireShield® MB Roof Coating is a water-based, liquid thermoplastic rubber coating that cures to form a seamless rubber membrane. FireShield® MB Roof Coating will maintain or may improve UL rating on select roofing systems or assemblies.* FireShield® MB Roof Coating 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 noncombustible carbon char layer is formed that retards flame propagation by reducing available oxygen. FireShield® MB Roof Coating (white only) is listed by the Cool Roof Rating Council 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.


Sizes Available:

5 gallon (18.9 liter) pail
54 gallon (204 liter) drum


Uses

United Coatings FireShield® MB Roof Coating is designed to restore BUR, modified bitumen, Hypalon®, TPO, EPDM, metal, wood, and concrete. FireShield® MB Roof Coating is formulated to provide maximum fire protection, increase a roof’s reflectivity, and 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. For proper installation, substrate must have positive drainage (i.e., 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 32°F. Substrate temperatures must be below 120°F when applying product.



Advantages

  • FireShield® MB Roof Coating is highly reflective
  • FireShield® MB Roof Coating (white only) is listed by the Cool Roof Rating Council for solar reflectance and thermal emittance
  • Ideal for modified bitumen, Hypalon®, BUR, metal, TPO, wood, concrete, and EPDM
  • Designed to be applied at temperatures as low as 32°F
  • Strong; forms a flexible seal that will not become brittle
  • Flexible; will expand and contract with roof
