To cure and cure. The cement mortar 3 is filled in the defect portion 2 so that the surface thereof is slightly recessed from the surface of the decorative coating film 10 of the ALC decorative panel 1. This cement mortar 3 is prepared by mixing cement with aggregate, and it is preferable to use early-strength cement as the cement so that curing is completed in about 1 to 3 days. Further, as the aggregate, pearlite, foamed shale, river sand, etc. can be used. However, since the ALC decorative panel 1 is formed of lightweight ALC, cement mortar is made by using lightweight pearlite or foamed shale as the aggregate. It is preferable to reduce the weight of 3 and make the physical properties of the ALC decorative panel 1 uniform in weight. The mixing ratio of cement and aggregate in this cement mortar is cement: aggregate = 40 to 6 by weight ratio.
0: 60-40 is preferable, and the water / cement ratio is W
/ C = 40 to 80% by weight is preferable.
