A spray gun is disclosed intended alternatively for the application of plaster to walls, and the application of particulate finishing materials to the wet plaster. The gun has a hand held stock supporting a tubular housing, which receives at its front end interchangeable barrels having apertures in their side walls which can be brought into coincidence with an aperture in the housing communicating with a supply of material to be sprayed. One barrel has a handle so that it can be rotated in the housing to adjust the degree of coincidence between the openings and thus control release of particulate material into the barrel, while the other barrel is provided with a nozzle for the spraying of plaster. Compressed air for carrying out the spraying is admitted through an axial pipe connected to an external trigger.

A hand held compressed air gun for spraying particulate materials comprising a hand held stock supporting a tubular housing, a barrel member having a breech end rotatably supported in the tubular housing, a handle attached to the barrel forwardly of the housing whereby the latter may be manually rotated relative to the tubular housing, means for mounting a hopper for particulate material on the tubular housing above an opening defined therein, the breech end of the barrel defining a further opening in the side wall of the barrel whereby on rotation of the barrel there is a continuously variable degree of coincidence between the opening in the breech end of the barrel and the opening in the breech block, and an air supply pipe extending axially through the breech block and the breech end of the barrel to a nozzle adjacent the opening therein and directed towards the nozzle end of the barrel, whereby to eject material falling into the barrel from the hopper.
