How long must the minimum temperature of 40°F be maintained after the application of SFRM?

Maintaining the minimum temperature of 40°F after the application of Spray-Applied Fire-Resistive Material (SFRM) is essential for ensuring proper curing and adhesion. When SFRM is applied, it undergoes a chemical process that requires a certain temperature range to ensure the material can set effectively. Maintaining this temperature for at least 24 hours allows the SFRM to cure properly, thereby achieving the necessary fire-resistant properties and ensuring the material bonds adequately to the substrate it's applied to. If the temperature falls below this threshold for an extended period right after application, it could hinder the curing process, potentially compromising the integrity and performance of the fireproofing. Therefore, upholding the specified minimum temperature for 24 hours is critical to achieving the desired fire protection standards and performance criteria.
