A method of treating a metal surface (1) of a mold for molding and curing rubber products is disclosed. The method comprises applying an atmospheric plasma comprising an ionized gas containing a polymerizable precursor to a metal molding surface of the mold metal surface to form and bond a polymer layer of plasma polymerized precursor on the mold metal surface (1).
