In this paper, the authors report the actual circumstances concerning repairing works of condominiums in Hokkaido. Especially the painting work of the external wall which costs the most expensive in repairing works is observed precisely. Used data on repairing works of condominium are based on questionnaires to administrators of condominiums and paniter's companies. As the results of the questionnaires, the most condominiums (of 81.2%) that aged ten years after construction are needed some repairs. In cases of condominium aged ten or more years, the expense of repairing external walls amounts to 45.1% 〜 54.8% of total repairing expense. Wall coatings for thin textured finishes occupied more than half of total amount of external materials of condominiums at seven years before. But the thin textured finishes decreases to 25.7% in these three years. On the contrary, ceramic tile is gradually increasing every year. External finish of condominiums is changing mostly from Wall coatings for thin textured finishes to multi-layer wall coatings for glossy textured finishes in chance of renewal of paint. The most defects on the external wall is crack. The recommended optimum interval of painting renewal is estimated to 5.9 years in case of wall coatings for thin textured finishes, to 7.2 years in case of multi-layer wall coatings for glossy textured finishes, to 7.5 years in case of wall coatings for thick textured finishes and 9.2 years in case of epoxy resin based multi-layer wall coatings for textured finishes. In case of thin textured finishes, the difference of the ideal interval between the real interval amounts to 3.9 years. This fact causes to diminish the durability of condominiums.
