Disclosed is a method for recoating an RTV anti-pollution flashover coating on an insulator coated with the RTV anti-pollution flashover coating. The insulator includes an insulator body, a steel cap connected to an upper surface of the insulator body, and a steel pin connected to a lower surface of the insulator body. The method includes: (1) wiping off dirt on a surface of the insulator; (2) determining whether the insulator can be recoated; (3) performing coating by using an RTV anti-pollution flashover coating with the content of solid being 55%-65%. After coating is performed, a newly coated anti-pollution flashover coating can be closely adhered to a surface of the insulator, swelling does not occur, adhesion of the coating with respect to the insulator is not reduced, the hydrophobicity of the surface is recovered, and non-reduction of a pollution flashover voltage of the insulator is ensured.
