FM Approvals (www.fmapprovals.com) tested and certified Firefree 88 water-based latex intumescent coating as the first and only intumescent coating to pass the FM 4470 (NFPA 276) roof assemblies for use in Class 1 and non-combustible roof deck construction assemblies.

Previously, all FM-approved coatings were limited to steel roof decks. Firefree 88’s first approval was in 2004, when it was tested in accordance to FM 4975 and Part 1 of FM 4880. 

Firefree 88 is an intumescent coating that can be applied to a variety of materials. It prevents flame spread and reduces smoke generation to the coated substrates. Test results have shown that Firefree 88 is able to withstand temperatures up to 2,200 °F.   

The coating is non-toxic, eco-friendly and applies as easily as paint.  Because of its ease of application and minimal inconvenience to occupants, Firefree 88 is a very cost-effective and time-saving solution versus solutions that may increase the load on a structure. This often results in a conservative 50% to 70% savings (traditional methods can also add extensive disruption to occupants). 

Firefree 88 can be applied over most existing latex paint, or it can be top coated with latex paint, which will not impact the performance of the coating.
