PROBLEM TO BE SOLVED: To aim a dry curing stabilization of a water based thick film type paint material, and to prevent occurrences of film defects such as blistering, peeling, and cracking. SOLUTION: After the water based thick film type paint forming the film in which a dry film thickness is 0.2 mm or more is applied to a base material, a humid-permeable water repellent agent is applied to cure the water based thick film type paint material. The humid-permeable water repellent agent contains as a bonding agent a synthetic-resin emulsion (A), in which an acrylate resin derived from (metha)acrylic acid alkyl ester and a silicon resin derived from a cyclic siloxane compound are mixed in an emulsion particle at the weight percent of 99:1-30:70.
