When can visual inspection of TFIFRM take place?

Visual inspection of Thermal Fireproofing Insulation for Reinforced Metal (TFIFRM) is most appropriately conducted after the drying or curing process. This is essential because the effectiveness and integrity of the fireproofing material can only be accurately assessed once it has reached the required hardness and durability.

Inspecting after drying or curing allows for the identification of any defects, inconsistencies, or failures in the application that may not be apparent while the material is still wet or in the process of setting. The curing stage is critical as it ensures that the fireproofing achieves its intended fire-resistance properties, and only once this stage is complete can a thorough evaluation of the installation be reliably conducted.

While visual inspections can occur during application or even after the application is completed, these times do not provide a complete assessment of the material's performance or adherence to standards, as the product’s properties are not yet finalized. Conducting inspections prior to application also does not contribute to evaluating completed work, which is why the phase after drying or curing is the most appropriate time for thorough visual inspections.
