To provide an anticorrosive coating method using a simple surface treatment method to a rust surface.SOLUTION: An anticorrosive coating method for a rust surface includes a surface treatment step (1) for performing surface treatment of the rust surface by coating surface treatment liquid (A) containing water and an organic solvent (a1) in which the amount of the organic solvent (a1) occupied in the whole treatment liquid is in the range of 0.1-65 mass%, on the rust surface with a coating amount in the range of 50-550 g/m, so as to be impregnated thereinto, and a primer coating step (2) for coating a water-soluble anticorrosive paint (B) on a surface treatment part obtained in the step (1).SELECTED DRAWING: None 【課題】錆面に対する簡易な下地処理方法を用いた防食塗装方法を提案する。【解決手段】錆面に、有機溶剤（ａ１）及び水を含み、全処理液中に占める有機溶剤（ａ１）の量が０．１〜６５質量％の範囲内である下地処理液（Ａ）を、塗布量５０〜５５０ｇ／ｍ２の範囲内で塗装し含浸させて錆面の下地処理をする、下地処理工程（１）、工程（１）で得られた下地処理部に、水性防食塗料（Ｂ）を塗装する下塗り塗装工程（２）を含む、錆面の防食塗装方法。【選択図】なし
