ABSTRACT:
A painting apparatus selectively sprays a plurality of different color paints by a pair spray gun at a desired discharge rate. A thinner is discharged into a pipe communicating the spray gun so as to force out a selected color paint remainiung in the pipe for continuously spraying the color paint. A flow meter is disposed in the pipe to measure the color paint flowing therethrough so as to detect its flow rate. A thinner discharge rate at which the thinner is discharged, is controlled according to the flow rate so as to spray the color paint at a substantially constant rate before and after the discharge of the thinner into the pipe.
