How long after the application of SFRM should the minimum temperature be maintained?

• A. 12 hours
• B. 24 hours
• C. 48 hours
• D. 72 hours

Answer: (B)

Maintaining the minimum temperature for a specified duration after the application of Spray-Applied Fire-Resistive Material (SFRM) is crucial for ensuring effective bonding and curing. The ideal timeframe is 24 hours, during which the material needs to cure properly to achieve optimal performance and fire resistance. This period allows the SFRM to adhere well to the substrate and develop the necessary physical properties. Proper temperature control during this initial period minimizes the risks of issues such as inadequate curing, which could compromise the fire-resistive characteristics of the material and, consequently, the safety of the structure. Therefore, adherence to the 24-hour minimum temperature maintenance guideline is essential for both the integrity of the application and the overall safety standards required in construction practices.
