What is one requirement for maintaining SFRM during application?

Maintaining SFRM (Spray Fire-Resistive Material) during its application is critical for ensuring the material adheres properly and performs effectively. One important requirement is that both the ambient and substrate temperatures must be at a minimum of 40 degrees Fahrenheit. This temperature threshold helps to ensure proper curing and bonding of the material, reducing the risk of performance issues in fire resistance.

If the temperatures are too low, the application could lead to inadequate adhesion, improper curing, or potential freezing of the product, all of which could compromise its fire-resistive properties. This is particularly significant in construction and fire safety contexts, where the integrity of fire-resistant materials is paramount. Adhering to the appropriate temperature range helps to ensure that the SFRM will provide the intended level of fire protection, thereby promoting safety and compliance with building codes or regulations.
