PROBLEM TO BE SOLVED: To provide a coating technique for a concrete product by which the concrete product can be coated simultaneously with molding thereof to improve the operating efficiency and thereby the surface of the coat is smoothed and further, the concrete product gains luster on the coated face to make it appear as if it were polished. SOLUTION: A coat 3 is formed by applying a coating on the molding face of a form 2 for molding a concrete product (a car stop block 1) and then concrete 10 is formed in the form to obtain the concrete product. Finally the coated face 3a is formed on the outer face of the concrete product by transferring the coat.
