<p>The invention relates to a method of decorating metal parts through the application of powder paint. The inventive method comprises the following steps: application of a first coat of powder paint by means of electrostatic deposition on the metal surface to be decorated, thermal treatment of said first coat, application of a second coat of powder paint in selected zones of the first coat using a screen printing mesh in order to produce a decorative design and a final thermal treatment of said first and second coats in order achieve combined polymerisation of both coats. The invention is characterised in that the size of the particles forming the second coat of powder paint is less than 40 micra and in that, following the application of the second coat using the screen printing mesh, said second coat is subjected to a thermal treatment by means of the application of infrared radiation in localised zones, in order to bring the second coat to a gelatinous state which is used to fix same to the first coat. In this way, the metal part can be handled without moving the particles of the second coat of paint. The inventive method is suitable for use in decoration for applying a decorative layer which replicates a natural finish such as marble or wood.</p> |
