How often should the spray gun for applied fireproofing be calibrated?

The frequency of calibrating the spray gun for applied fireproofing is critical for ensuring consistent application quality and achieving the desired fire-resistance rating. Regular calibration, typically before each project, helps maintain accuracy in the mix of materials being sprayed, which can vary due to factors such as material viscosity, temperature, and environmental conditions.

By calibrating before each project, you ensure that the spray gun is delivering the correct amount of fireproofing material, which is crucial for meeting building codes and safety requirements. This practice not only enhances the effectiveness of the fireproofing but also prevents costly rework or failure to meet compliance standards.

In contrast, calibrating only once a month, once a year, or assuming that calibration is not necessary does not provide the same level of assurance. These less frequent calibration strategies can increase the risk of inconsistencies in material application, potentially compromising the fire-resistance characteristics of the structure. Thus, regular calibration practices help promote safety and compliance in fireproofing applications.
