PROBLEM TO BE SOLVED: To provide a surface treating method for a resin covering member formed by stacking a plurality of resin layers including a thermoplastic resin layer and a thermosetting resin layer on a metal substrate, efficiently separating these resin layers at low cost, and not damaging the substrate. SOLUTION: This surface treating method is provided for the resin covering member formed by sequentially stacking at least one thermoplastic resin layer and at least one thermosetting resin layer on the metal substrate. In the method, after the thermosetting resin layer is separated by blasting, the thermoplastic resin layer is removed by thermal cracking using high-temperature water vapor and hydrolysis.
