What role does relative humidity play during the application of TFIFRM?

Relative humidity is a critical factor during the application of Thermal Fireproofing Intumescent Fire-Resistant Material (TFIFRM) because it affects the drying time of the material. When the humidity level is high, it can slow down the evaporation of water present in the TFIFRM, leading to extended drying times. Conversely, low humidity can speed up drying, but it may also lead to issues like uneven application or defects. Proper management of drying time is essential for achieving the correct properties of the fireproofing material, ensuring that it adheres well to the substrate and cures as intended. This understanding is vital for anyone involved in fireproofing, as it directly impacts the effectiveness of the fire protection system being applied.
