Traditional architecture are subject to a wide variety of damage. However, it is difficult to repair maintaining damaged parts. The authors developed a method of repairing lath and plaster members using acrylic resin. This repair method is applied from the back side of the plaster member, so appearance of the finish material is maintained. In this paper, we applied this repair method to Iwate Bank's plaster ceiling. As a result, it was found that this method can repair a large area with compact equipment and materials and can adapt to wide variety of damage.
