PROBLEM TO BE SOLVED: To provide a curing method of a cement hardening object obtaining a high expansion amount, reduced in drying contraction and having a high crack resistance, and a drying-contraction reduction method. SOLUTION: The curing method of the cement hardening object or the drying-contraction reduction method includes the step of coating the cement hardening object with a curing coating agent primarily consisting of a synthetic resin aqueous dispersion body, a water soluble resin, and a high-swelling clay mineral. Furthermore, the coating amount of the curing coating agent is 10 to 300 g/m<SP>2</SP>, and the cement hardening object contains cement and an expansion agent or a drying contraction reduction agent.
