How long must substrate temperatures be maintained after applying TFIFRM?

The duration for which substrate temperatures must be maintained after applying Thermal and Foamed Insulation Fire-Rated Material (TFIFRM) is critical to ensuring effective fireproofing. Maintaining these temperatures for 72 hours allows for proper curing and adhesion of the fireproofing material to the substrate, which is essential for maximizing its fire-resistance capabilities.

During this 72-hour period, the thermal properties of the substrate can stabilize, reducing the risk of moisture ingress or other environmental factors that could impair the performance of the applied fireproofing. This maintenance duration also aligns with industry standards and best practices that have been established to optimize the effectiveness of fireproofing materials. Overall, adhering to this guideline is crucial for achieving the desired fire resistance and performance of the applied system.
