How does improper SFRM application typically manifest during inspection?

Improper application of spray-applied fire-resistive materials (SFRM) can lead to inconsistent thickness readings during inspection. This is critical as the effectiveness of fireproofing materials is highly dependent on their thickness; too thin an application can compromise fire resistance, while too thick can lead to cracking or other structural issues. Inconsistent thickness indicates that the application process was uneven, possibly due to inadequate technique or equipment malfunction, affecting the overall performance and integrity of the fireproofing system.

Uniform surface appearance would suggest a well-applied SFRM, where the material was uniformly distributed, indicating that the application was carried out correctly. High bond strength values would reflect effective adhesion between the SFRM and the substrate, which is desirable in fireproofing applications. Excessive weight, while a potential concern, does not typically emerge as the primary indicator during inspections, as it can result from various factors and does not directly reflect the application quality of SFRM.
