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.

A spray device comprising: a) a reservoir for containing a charge of relatively viscous wall texturizing material or a charge of relatively non-viscous paint; b) a cap removably fitted on a bottom of said reservoir, an interior of said cap being in direct communication with an interior of said reservoir in order that the material tends to gravity flow into said cap interior; c) a discharge nozzle suitable for discharging said relatively viscous texturizer material, said discharge nozzle including an entry end disposed within said cap, a discharge end projecting outwardly of said cap, and a bore extending between said entry end and said discharge end; d) an air nozzle for discharging compressed air within said cap, said air nozzle being aligned with said entry end of said discharge nozzle; and e) an adapter for removable placement in said cap to convert the device from a first configuration suitable for spraying said relatively viscous wall texturizing material to a second configuration suitable for spraying said relatively non-viscous paint, said adapter including i) an outer tube coaxially receivable within the bore of said discharge nozzle and having a discharge end, an inboard end directed toward said air nozzle, and at least one aperture formed intermediate said discharge end and said inboard end for admitting material from said reservoir; ii) an inner tube coaxially carried within said outer tube and including a discharge end disposed between said at least one aperture and said discharge end of said outer tube, and an inlet end for receiving compressed air from said nozzle; and iii) attachment means for detachably securing said outer tube to said discharge nozzle.
