What is the minimum allowable temperature during TFIFRM curing?

The minimum allowable temperature during TFIFRM (Thermoplastic and Fire Resistance Material) curing is set at 50 degrees Fahrenheit. This temperature is critical for ensuring effective curing of the fireproofing material, as the chemical reactions required for proper adhesion and hardening of the material depend on maintaining adequate temperature. If the temperature falls below this threshold, it can lead to incomplete curing, affecting the fireproofing material's performance, integrity, and overall effectiveness in providing fire resistance. Curing at temperatures lower than 50 degrees can also result in various defects, such as chalking or flaking, which would compromise the protective layer intended to shield structural components from fire. Keeping the curing environment above this minimum ensures that the properties of the material are properly developed and that the fireproofing meets the required safety standards.
