There are disclosed a method and apparatus for applying a strippable paint to a large-sized product finished with a sprayed coating, such as an automobile, to form a protective film on the surface of the coating. The product is conventionally kept in stock for a period of time before it is shipped. Contaminations such as dust are washed away from the surface of the product. Then, the strippable paint is applied, preliminarily dried, and non-preliminarily dried to form the protective film out of the strippable paint on the surface of the coating. This protective film is formed easily, appropriately, and reliably. The obtained protective film has a uniform and sufficient thickness. Even if the surface contains unapplied regions to which the paint should not be applied, the paint can be applied to the whole surface of the coating while avoiding the unapplied regions according to the invention. The application can be performed easily and reliably without leaving unapplied portions around the unapplied regions.

Method for forming protective film of strippable paint on sprayed coating of automobile or other large-sized product

A strippable paint is poured down onto coated surfaces,and,of an automobile V within regions to be protected, from a plurality of nozzles,disposed in parallel in a widthwise direction of the automobile V above the coated surfaces,and,of the automobile V, while controlling the number of nozzles which are used to discharge the strippable paint, in accordance with the extent of the regions to be protected. Thereafter, the strippable paint is spread over an entirety of the coated surfaces,and,in the regions to be protected. Thus, the region covered by each of the nozzles can be relatively reduced to efficiently carry out the pouring-down of the strippable paint and to prevent dusts of a coating material from being scattered to a wide range. In addition, the need for a masking step and/or an inspecting/correcting step can be eliminated to reduce the operating steps and further to alleviate the operational load.

Process for forming protective film on coated surface of automobile

In peeling off, from a coating surface, temporarily protecting coating films formed by applying a protecting coating material onto the coating surface after completion of the coating, high-pressure water is jetted toward between the coating surface and end edges of the temporarily protecting coating films to peel off the end edges from the coating surface. Then, the high-pressure water is jetted sequentially to between the coating surface and peeled-off portions of the temporarily protecting coating films from the coating surface to peel off the entire temporarily protecting coating films from the coating surface. Thus, the temporarily protecting coating films can be easily peeled off without being influenced by the temperature of an environment, leading to a shortened peeling-off time.

A spraying booth comprising a spraying area defined by a ceiling and side walls. The ceiling includes top feed openings connected with a feed duct extending from a conditioner for controlling a fresh air temperature. The side walls include side feed openings connected with a blast duct for supplying air from which paint mist has been removed at mist removing devices. Fresh air supplied through the top feed openings and the mistless air supplied through the side feed openings combine to produce an advantageous atmospheric condition for a paint spraying operation.
