Process for peeling off temporarily protecting coating film

摘要

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.
