More about Historical: Gypsum Spray Fireproofing - 2015

Gypsum spray fireproofing is applied to structural steel beams, columns, joists, and floor and roof decking to insulate it from high heat produced during a fire and to prevent (or delay) the loss of structural integrity. It is sold in dry mix bags which are then mixed together on site with potable water and sprayed onto un-primed steel. The wet mix density and spray rate must be carefully controlled so that a minimum dry density of 15 pcf (240 kg/m3) is achieved. Gypsum spray fireproofing is applied after all construction work on the application area is completed in order to limit disturbance to the set material. However, ducts, piping, and conduit must be installed after fireproofing has been completed.
