Gypsum composition for dry-curing coating material, gypsum-based coating material, and construction method for gypsum-based coating material
Provided is a gypsum composition for a dry-curing coating material capable of forming a coating film in which color unevenness is suppressed while being thin and smooth when made to be a gypsum-based coating material by adding water. This gypsum composition for a dry-curing coating material contains a hemihydrate gypsum with an average particle diameter of no more than 50 μm, calcium carbonate with an average particle diameter of no more than 50 μm, and a setting retarder, the calcium carbonate content being 10-400 parts by mass and the setting retarder content being at least 0.1 parts by mass per 100 parts by mass of the hemihydrate gypsum.
