ABSTRACT OF THE DISCLOSURE 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 has a body defining a handle section and a nozzle assembly coupled to the body and having a central opening for the discharge of a stream of said particulate material and liquid discharge means disposed around said opening for the discharge of liquid around said stream of parti- culate material. The body includes a first air passageway adapted to be supplied with pressurized air and coupled to said central opening of the nozzle assembly. A second air passageway is also provided and is adapted to be supplied with pressurized air and is coupled to said liquid dis- charge means of the nozzle assembly. First liquid inlet means is provided for the introduction of said particulate material into the first air passageway. Second inlet means is also provided, through which said liquid can be introduced under pressure into the second air passageway and the body also includes means for controlling the intro- duction of said particulate material into the first air passageway. The gun has a trigger mounted on the body adjacent the handle section for progressive movement with respect to said body from a rest position, the trigger being positioned so that it can be squeezed towards said handle section by a person holding the gun by said section. Spring means is provided normally biassing the trigger to its said rest position. An air flow control valve is disposed in the first air passageway and is coupled to the trigger so that the valve is progressively opened as the trigger is squeezed. The second inlet means includes a liquid flow control valve coupled to the trigger so as to be progressively opened as the trigger is squeezed. This allows the volume of liquid and the amount of par- ticulate material issuing from the gun to be simultan- eously varied in use by operation of the trigger.
