Before World War II, finish materials used on exterior walls in Japan included tile, terracotta, mortar, steel and paint. Though many of these buildings have been designated as cultural properties, approximately 60% of these original finish materials have been remained. The author notes that there are four types of procedures which are followed: repair, restoration, resemblance and alteration. Although many buildings retain original materials in their exterior walls, resemblance and alteration in replacement materials, such as paints, are being used which were unavailable when they were first built. This presents two conservation-restoration dilemmas. First, the original exterior wall materials are being lost, and second, the overall value of the buildings decreases.
This paper, drawing on conservation - restoration research, will make recommendations for the replacement of finishing materials on the exterior walls of pre-war reinforced concrete - construction buildings. The paper concludes that care should be taken when retain original materials whenever possible, and / or when choosing replacement materials.
