The mass to be sprayed by the spray gun is stored in an airtight closed storage container. A cushion of pressurized air is generated above the level of the paint mass present in the storage container. This air cushion is fed by means of a manually operated piston pump projecting into the storage container. Accordingly, the mass to be sprayed and fed via the feed line extending to the spray gun is pressurized. Conclusively the feed line can be designed with a longer dimension, the mass to be sprayed can be more viscous and the distance in height between storage container and spray gun can be much larger.
