Abstract
A method and apparatus for controlling the flow rate of relatively low viscosity fluids, such as accelerators, in viscous, hydraulic slurry spray application systems. An adjustable accelerator flow control system which regulates excess air pressure supplied to the accelerator pump in response to height variations of the spray nozzle is provided. The system is especially useful with fireproofing compositions since it provides effective distribution and constant flow of a viscous, hydraulic cementitious slurry with an acidic accelerator.
