Which conditions must be monitored during SFRM handling and mixing?

• A. Humidity and air pressure
• B. Substrate temperatures and surface conditions
• C. Airborne particulates and temperature
• D. Application pressures and surface textures

Answer: (B)

When handling and mixing Spray-Applied Fire-Resistive Material (SFRM), it is crucial to monitor substrate temperatures and surface conditions because these factors significantly influence the performance and adherence of the fire-resistive coating. Proper substrate temperature ensures that the SFRM properly cures and bonds to the surface, while the surface conditions, including cleanliness and texture, can affect the material's ability to adhere effectively. If the substrate is too cold, for instance, the curing process may be impaired, leading to poor performance of the material under fire conditions. Similarly, if the surface is contaminated or improperly prepared, it can result in delamination or failure of the coating. Monitoring these conditions helps ensure that the application meets fire protection standards and performs as intended during a fire.
