<p>PROBLEM TO BE SOLVED: To polish a surface of an existing building structure.SOLUTION: A transparent cover having a shape covering a surface to be processed covers the surface to be processed to form an electrolytic solution space. Sealing means seals between a periphery of the transparent cover and the surface to be processed in a liquid-tight manner. A net-shaped electrode (net electrode) is disposed in the electrolytic solution space while holding a clearance between the transparent cover and the surface to be processed, and a net-shaped insulation plate is disposed on a side of the surface to be processed of the electrode. An inlet port and an outlet port of electrolytic solution are provided for any position of the transparent cover, and furthermore, a ventilation port is provided for the transparent cover so as to communicate with outside air. The transparent cover is fixed to the surface to be processed by fixing means. As the fixing means, a suction pad which sucks onto a portion near a region to be processed of the surface to be processed having a planar or curved-planar shape can be used.</p> |
