Abstract
A hot air gun for drying a sprayed air-dryable liquid material is disclosed. The gun includes a hot air gun connected to both a source of hot pressurized air and a source of flowable air-dryable liquid material. The gun includes a body having a handle assembly and a spraying assembly. The handle assembly includes a depressible trigger and first knob for adjusting the amount of flowable liquid material in the spray and a second knob for adjusting the pattern of the spray. The spraying assembly includes a spray nozzle and control valves operably connected with the trigger for controlling the flow of pressurized hot air and liquid material. An air diverter is fitted between a port for allowing passage of air into the gun and the spray nozzle for diverting hot compressed air onto liquid material sprayed on a substrate.
