ABSTRACT:
A hand-held apparatus for spraying texture material including a body, a pressurized air source mounted on the body, a texture material hopper mounted on the body, and a texture delivery nozzle for selectively spraying texture material from the hopper onto a surface to be coated by propelling the texture material using pressurized air from the pressurized air source wherein each of the air source and the hopper can be disconnected from the body without the use of tools. An air directing plunger has a plurality of discontinuities at an outlet thereof, which may be radially outwardly directed recesses or radially inwardly directed teeth for reducing the noise generated by the pressurized air during operation.
