Abstract
A method is provided whereby the setting time of a spray applied hydraulic cement-based fireproofing composition is decreased substantially while improving the yield of the composition. An acidic set accelerating agent is thus introduced into the composition effectively after conveyance through the system and in close proximity to the spray nozzle. At least about 0.5% of a basic material is provided which evolves a gas upon reaction with the accelerating agent. The invention also relates to the sprayable fireproofing compositions resulting from operation of the method.
