More about Gypsum Spray Fireproofing

Gypsum Spray Fireproofing is a class of Spray-Applied Fire Resistive Materials (SFRM), which are used to protect structural steel in the event of a fire. Products typically have a fire resistance rating of up to four hours. Depending on the application, SFRM products can be specified as normal (15-18 pcf), medium (22-30 pcf), or high density (≥40 pcf), referring to product density in the cured state. This CP covers normal density SFRM products, which use gypsum as a binder and are typically used in covered or protected areas. For information on medium density products, see Cementitious Fireproofing (Medium Density 22-30 pcf). Values below are dry weight percents as the product is supplied as a dry powder that is mixed with water on site prior to being spray applied. A set accelerator composed of aluminum sulfate powder may optionally be added on site to reduce the set time; it may also function as a foaming agent by reacting with basic materials, like calcium carbonate, to release carbon dioxide.
