PROBLEM TO BE SOLVED: To provide a coating method by which a multi-layered coating film excellent in weather resistance and durability can be formed by a few coating processes for the purpose of protection and beautiful appearance maintenance of concrete structure for civil engineering and construction. SOLUTION: After the concrete structure is coated with polymer cement mortar paint (I), a paint composition (II) comprising an acrylic resin (A), an epoxy resin (B) having at least two epoxy groups in a molecule and an amine hardener (C) which can contain aminosilane is applied thereon. In this coating method, the paint composition (II) may further contain an organosilane compound (D) and at that time, a compounding rate of the acrylic resin (A), the epoxy resin (B) and the organosilane compound (D) is suitably (A) 5 to 95 wt%, (B) 5 to 95 wt% and (D) 0 to 90 wt% in these total resin solid content.
