PROBLEM TO BE SOLVED: To easily and efficiently perform the repair of a polymer cement hardened material, further, to make crazing, cracking, peeling or the like hard to be generated in a repaired part, and to reduce deterioration in strength and durability. SOLUTION: The method for repairing the chipped part of a polymer cement hardened material obtained by forming a polymer cement material composed of W/O type emulsion comprising cement and a vinyl-based monomer and hardening the same includes: a stage (a) where a repair material obtained by kneading a vinyl-based elastic polymer aqueous solution and a hydraulic material is filled into the chipped part of the polymer cement hardened material, so as to be raised; and a stage (b) where, after the hardening of the repair material, the repair material hardened matter is ground, so as to be shaped.
