An improved spray apparatus designed to optimize the pattern of the texture material and the performance of the spray apparatus to look and perform similar to a hopper texture gun or texture spray rig used by professionals. The spray apparatus, has a housing defining a cavity. A transfer wheel is rotatably mounted to the housing, the transfer wheel having a hub defining a hub axis, and a plurality of transfer flaps. A propeller is rotatably mounted to the housing and positioned above the transfer wheel, the propeller having a spindle and a plurality of fins. A firing pin is attached to the housing above the propeller. An actuator is mounted to the housing to cause the propeller to rotate. A gate may be provided to control the flow of the material to the transfer wheel.
