PROBLEM TO BE SOLVED: To provide a refractory coating material which can be sprayed on a surface of a desired base material portion using hemihydrate gypsum recycled from discarded gypsum board as a main raw material. SOLUTION: A refractory coating material composed of a hemihydrate gypsum component extracted from waste gypsum and a finely divided powder component extracted from discarded concrete material. It is preferable that the refractory coating material is kept in a state where it can be sprayed by a normal sprayer and further contains a cellulosic fiber component. [Selection diagram] None
