A disclosed method for restoring electric erosion pits on the surface of a liquid silicone rubber housing shed comprises the following steps: using an RTV anti-pollution flashover coating as a first coating and coating the electric erosion pit surface, so as to enable the pit surface to be smooth; using a single-composition RTV restoring glue as a second coating to fill and level up the electric erosion pits, and tightly binding with the first coating; and using the RTV anti-pollution flashover coating as a third coating and coating the second coating. The method is capable of effectively restoring the appearance and the performances of the liquid silicon rubber housing shed subjected to electric erosion.
