The plaster-spraying machine, suitable in particular for textured spraying, is equipped with motor (8), gear mechanism (9), plaster-material container (5), pump (11) and spraying gun (14) with compressed-air connection (18). The machine forms a unit for one-man operation. It is constructed in the manner of a dumb-waiter and has a removable drive assembly (6, 7) which is arranged on the material container and drives the vertically arranged spiral pump (11). A control station (23) is provided beneath the funnel-shaped material container (5). Said control station (23) has a throughflow control valve for switching the drive motor (8) on and off. A mixture of material and compressed air results in the spraying gun (14). The throughflow control valve is installed in the compressed-air line (18), the piston of which valve switches the drive motor (8) via a spring-loaded piston rod. This plaster-spraying machine is space-saving and constitutes a lightweight construction, which permits the unit to be designed as a one-man unit with extremely simple controlling means. <IMAGE>
