Abstract— When using a spray gun, grasp the distance between the object and the spray gun and the overlap of painting by spray distance, and well-balanced paint quality results can be obtained when maintenance painting work is performed. The width of the spray pattern is formed in a vertically long elliptical shape and when the spray gun moves, it is difficult to form a paint film at the edge of the paint because the discharged pressure is low and the density of the paint is low. The paint sprayed with the spray gun has the property that the central part of the object to be coated is the thickest and becomes thinner toward the edge due to the difference in density. In order to obtain a target coating film thickness with a set number of sprays, the width of the coating pattern for each spray distance must be considered. On the standard painting conditions for automobile repair painting, when the distance between the object to be coated and the spray gun is about 12 to 15 cm and when the feed speed of the spray gun is about 0.3 ~ 0.5 m/s, it is possible to form the thickness of the coating film according to the paint manufacturer's manual.
