During construction, Sprayed Fire-Resistive Materials (SFRM) and Thin-Film Intumescent Fire-Resistive Materials (TFIFRM) can be applied to steel components such as columns, joists, beams and decking. These materials encapsulate, or coat the structural steel components to protect from fire damage. There are two common types of SFRM: Cementitious and Sprayed mineral fiber.
Cementitious fireproofing is made of either gypsum plaster or Portland cement. These are mixed with water and sprayed into place, forming a uniform, monolithic finish. Sprayed mineral fiber is blown onto the component through a hose, forming a thick coating that is furry in appearance. Both of these SFRMs are intended to be hidden behind interior or exterior finishes, such as drywall or precast panels.

TFIFRM is a water or solvent-based thin film of intumescent paint. It is typically applied by spraying and is virtually invisible. In the intense heat of a blaze, this film will soften up and expand to form a thick meringue-like layer that insulates the steel for a period of time, generally up to two hours. Intumescent coatings allow architects to design their buildings with exposed structural steel while still maintaining the level of fire protection that is required  It is also beneficial because the coating can be colored to match the surrounding   architectural elements.

When a contractor is using fireproofing materials, it is also important to have the materials inspected. Inspection confirms that the product was applied within the tolerance level specified in the contract documents and product specifications. Inspection of the SFRM consists of thickness measurements, density tests, and cohesion/adhesion tests.

.Thickness is determined by inserting a penetrating pin through the SFRM to the substrate. The higher the hour rating requirement is for a structural component, the thicker the SFRM should be.

.Density testing of the SFRM consists of removing a known volume of SFRM from a structural component and drying the material to a constant weight to determine the weight per volume. This is typically done in a laboratory setting.

.The third test is the cohesion/adhesion test, which is performed to determine the bond strength of the SFRM to the steel component. A cap with a hook in the center is bonded to the SFRM using an adhesive. A pull type weight scale is then engaged to the hook and a pulling
force is applied until the SFRM has a cohesion or adhesion failure or until the product specifications are met.

The inspections performed for the TFIFRM consists of wet or dry thickness measurements
Wet thickness measurements are performed using a wet paint gauge. The dry thickness measurements are performed utilizing coating thickness gauge that measures the non-magnetic coating applied to the ferro magnetic base
