To provide a method for repairing a coating film, which is capable of conveniently repairing a defective part of the coating film without requiring a process of color tone works, or the like, and allows the coating film of a repaired surface and an unrepair surface to have a same color tone.

The method for repairing the coating film comprises a process (1) of sanding the defective part of the multilayer coating film composed of a base coating film formed with an aqueous base coating material and a clear coating film formed with a clear coating material, a process (2) of applying a repairing coating material on a ground part, and a process (3) of subsequently applying a repairing clear coating material. The repairing coating material is composed of an aqueous base coating material and an alcoholic organic solvent whose solubility to water is infinity and whose evaporation rate is ≥60, wherein the evaporation rate of butyl acetate is set to 100.
