Keywords:Touch-up work, Adhesive sheet, Corrosion of the steel, Accelerated deterioration test

At the time of using a hanging scaffold in repainting work of a steel bridge, a clamp mark remains after changing a catch clamp, and need the touch-up work to this part. It is pointed out that this part degrades earlier than the general part. Therefore, we have developed the repair material that can reduce touch-up work. As a result of evaluating the performance of the developed repair material, the following things became clear : no change such as peeling or swelling is observed even after the accelerated deterioration test, and the corrosion of the steel which is the adhesive part is suppressed. And, the adhesive sheet had the necessary performance as the substitute for paint for bridge.
