ABSTRACT OF THE DISCLOSURE A portable texturing system is disclosed which includes a small spray unit and a source of portable compressed air which may simply be a small tank which the workman may wear on a belt or shoulder harness. The spray unit includes a reservoir for holding a charge of texturizing mixture and a cap assembly incorporating a mixer/spray mechanism. In use, the cap is positioned below the reservoir such that the texturizing mixture can flow by gravity and suction to the spray mechanism. The cap assembly includes a quick connect coupling and a valve for receiving and controlling air from the supply. A discharge nozzle is provided for directing the compressed air/texturizer mixture toward a wall area to be texturized. A mixing region within the cap assembly permits the texturizing mixture to be entrained with a stream of compressed air and discharged from the nozzle whenever the valve is actuated. Adjustment structure for regulating the rate at which the texturizing material is entrained is provided in the mixing region and, in some embodiments, is adjustable as by a mechanism which provides adjustment to the area available for the texturizing material to enter the discharge nozzle. In one particularly simple and reliable embodiment, the area is established by the provision of a pair of fixed size apertures in the wall of a tube which also serves as the discharge nozzle.
