| description | PROBLEM TO BE SOLVED: To provide a surface modifier for a hardened cementitious body which prevents the body from undergoing surface color unevenness and to provide a method for producing a hardened cementitious body. SOLUTION: The present surface modifier for the hardened cementitious body comprises an aqueous solution containing 1 mass% to saturation concentration alkali metal hydrogen carbonate and/or an alkali metal carbonate, 5 mass% to saturation concentration water retention agent, and 0.3 to 0.7 mass% thickening agent. The present method for producing the hardened cementitious body comprises (A) the step of kneading a mixture containing at least cement and water and pouring the kneaded mixture into a mold to form an unhardened molding, (B) the step of primarily curing the unhardened molding to obtain a hardened molding, (C) the step of removing the molding from the mold and coating the surface of the removed molding with the above surface modifier, and (D) the step of secondarily curing the coated molding to obtain the hardened cementitious body.
