ABSTRACT OF THE DISCLOSURE: A method for producing coloured, patterned, homogeneous surface-structures based upon thermoplastic synthetic materials, more particularly upon PVC, wherein freely flowing powders or particles are shaken continuously onto a carrier-belt in such a manner as to form a uniform layer, are sintered under the action of heat, until the thermoplastic synthetic material is plasticized, in order to form a coherent, porous surface-structure which is then cooled. At least one liquid or freely flowing, fusible, coloured medium is applied in predetermined patterns and penetrates into the sintered layer to the desired depth, more particularly through the entire thickness of the layer, and the coloured, sintered layer is thereafter compacted, under the action of pressure and heat, to form a compact surface-structure.
