When patching SFRM, which type of material is permissible to use?

When patching Spray-Applied Fire-Resistive Material (SFRM), it is critical to use the same SFRM that was used on the project. This is because different SFRM products can have varying properties, including their fire resistance, density, adhesion characteristics, and application techniques. By using the same product, you ensure that the repair matches the original material in terms of its performance and compatibility.

Maintaining consistency with the SFRM used on the project is essential to uphold the integrity of the fire-resistive assembly. Different fireproofing materials may react differently under fire conditions, and using a different brand or formulation could lead to inconsistent fire protection, potentially compromising the safety of the structure.

In construction and fire safety, adherence to specified materials is a fundamental aspect of ensuring compliance with building codes and maintaining overall safety standards. This practice reflects a commitment to preserving the intended fire-resistance rating of the protected structure.
