What is the minimum ambient temperature that must be maintained during the application of SFRM?

• A. 30°F
• B. 40°F
• C. 50°F
• D. 60°F

Answer: (B)

The minimum ambient temperature that must be maintained during the application of Spray-Applied Fire-Resistive Material (SFRM) is critical to ensure proper adhesion, curing, and performance of the material. Maintaining a temperature of 40°F prevents issues such as inadequate bond strength, moisture problems, and improper curing that could compromise the integrity of the fire-resistive coating. Applying SFRM at or above this temperature allows the material to be adequately processed and developed into a protective layer capable of resisting fire for the designated time period. Lower temperatures can lead to various complications, thereby undermining the functional performance of SFRM in a fire safety context.
