ABSTRACT:
A spray applicator to discharge plaster or another texturizing material in a spray pattern against a wall surface or the like. There is a manually operated air cylinder and piston assembly which discharges pressurized air through a first nozzle, with an air jet traveling through an area where the plaster or the material descends from a container, with the air jet carrying some of the plaster through a forward discharge nozzle to cause a spray pattern. There is a rotatable adjusting sleeve which moves the two nozzles further apart or closer together to control the spray pattern and also to close the discharge nozzle.
