Abstract: The present invention relates to a process for obtaining a metal, ceramic or composite coating on the surface of a non-conductive material such as plastic, ceramic or wood which comprises: A) preparing a polypyrrole dispersion in aqueous base paint or in an acid type water-soluble pure resin; B) diluting the dispersion resulting from the previous stage with an alcohol in a factor of 1.5; C) applying the dispersion of the conductive polymer resulting from stage B) on the surface to be coated and drying same; and D) obtaining the metal, ceramic or composite coating by means of an electrolytic process or an electrophoretic deposition.
