A reverse painting process includes the preheating of work prior to its powder coating. By the preheating of the work, it becomes possible to form a film having a sufficiently large thickness for maintaining a satisfactorily high level of rustproofness in the boundary area between a film of the powdery paint and a film formed by electrodeposition, thus achieving drastic shortening of the time required for heating it in the fusing oven.

Reverse painting process

A powder coating booth for performing therein powder coating onto an article to be coated is divided into an automatic coating zone in which coating is performed only by automatic coating machines and manual coating zones in which coating is performed by a worker. A dry type of first recovering apparatus which recovers only that powder coating material in the automatic coating zone which has not been coated onto the article to be coated is provided separately from a second recovering apparatus which recovers that powder coating material in the manual coating zones which has not been coated onto the article to be coated. In this manner, the ratio of reuse of the recovered uncoated powder coating material is improved.
