A system for spraying granular pasty matrices onto buildings, the system including a spray gun for wet mortar which makes possible the easy, safe, and efficient spraying of wet mortar including aggregates with a particle size Dof between 1 and 15 millimeters. The spray gun is provided with a gun body with at least one injector emerging in a contacting chamber, at least one spray nozzle for mortar, and at least one connection end piece mounted on an inlet of a body for flow of mortar. Flow of mortar within a guiding duct of the body is monodirectional or multidirectional having angular deviation <30°. The position of an injection head of the injector in the chamber is adjustable. The mortar is constituted by a pasty matrix including aggregates, fillers and additives. The aggregates have a D=1-15 mm and a form factor F≠1.
