Abstract: The invention relates to a method for producing, applying and fixing a multilayer surface coating (2a, 3a) on at least one surface (1a) to be coated of a host substrate (1) in order to produce a host substrate assembly. Starting with a fixative product (2) and a functional product (3) based on single-walled or multi-walled graphene, the method consists in successively applying: a layer (2a) of fixative product to the or to each surface (1a) to be coated of the host substrate (1); and a layer of the functional product to said fixative layer (2a). The assembly can be finished with a protective layer deposited directly onto the layer (3a) that contains the functional product. The invention also relates to a host substrate assembly which can be obtained by said method, a heating element, an anti-corrosion and/or anti-fouling/dirt-repelling element and a hydrophobic element each comprising such an assembly.
