Spray applied fireproofing is used as passive fireproofing for a building and is typically referred to as Sprayed Fire-Resistive Material (SFRM). SFRM is a cement or mineral-fiber-based fireproofing material (e.g. gypsum) that is applied as a spray to steel beams and columns.

The technical name for Spray Applied Fireproofing is Sprayed Fire-Resistive Material (SFRM). It is used as part of a building’s passive fireproofing strategy. Spray applied fireproofing has thermal and acoustical properties and controls condensation.

Spray-applied fireproofing products are the most common types of fireproofing materials. Spray-applied fireproofing can either be cementitious fireproofing (typically gypsum-based, wet mix formulation) or sprayed fiber fireproofing (mineral wool fiber with a portland cement-based binder, dry mix formulation).

Cementitious fireproofing is often referred to as spray applied fireproofing. This coating is either gypsum or Portland cement-based and plays the role of passive fire protection.
