ABSTRACT:
A spray gun is disclosed for simultaneously spraying a liquid and a particulate material, for example, in applying decorative facings to walls and like surfaces. The gun is designed to spray a central stream of particulate material surrounded by a liquid stream. The gun includes a first air passageway into which the particulate material is introduced and a second air passageway into which liquid can be introduced under pressure. An air flow control valve is disposed in a first air passageway and is coupled to a trigger so that the valve is progressively opened as the trigger is squeezed. A flow control valve is also provided for the liquid and is coupled to the trigger so as to be progressively opened as the trigger is squeezed.
