GYPSUM COMPOSITION FOR DRY-CURING COATING MATERIAL, GYPSUM-BASED COATING MATERIAL, AND CONSTRUCTION METHOD FOR GYPSUM-BASED COATING MATERIAL
There is provided a gypsum composition for a drying type coating material, the gypsum composition, when made into a gypsum-based coating material by addition of water, capable of forming a coating film in which color unevenness is suppressed even though the coating film is thin and smooth. This gypsum composition for a drying type coating material contains hemihydrate gypsum having a mean particle diameter of 50 μm or less, calcium carbonate having a mean particle diameter of 50 μm or less, and a setting retarder, wherein the gypsum composition has a content of calcium carbonate of 100 to 400 parts by mass and a content of the setting retarder of 0.1 parts by mass or more each based on 100 parts by mass of the hemihydrate gypsum.
