ABSTRACT:
A low cost, hand-held sprayer that is pneumatically powered so that a wall or ceiling may be textured. The sprayer includes a hollow J-shaped body that is filled with a liquid texture material. An air passage communicates with an air supply and extends through the sprayer body to deliver respective streams of air to an exit orifice at the bottom of the body and to an air chamber at the top of the body. An air escape hole is formed through the sprayer body to communicate with the air chamber at a location above the material supply. By manually closing the air escape opening, a positive air pressure is created within the air chamber to force the entire column of material towards the exit orifice at the bottom of the sprayer body. Accordingly, air from the air passage is mixed with material and injected through the exit orifice to thereby discharge and atomize the material.
