The present invention relates to the use of a powder for coating articles, this powder comprising, by volume, 99 to 65% of at least one thermoplastic polymer and 1 to 35% of beads of a material that retains its initial shape at the processing temperatures for obtaining the coating. This powder may be prepared by simply dry-blending the constituents. The invention also relates to this powder. The invention relates in particular to rough coatings obtained from powders, for a dishwasher basket, which contain solid or hollow glass or ceramic beads added by dry-blending them with the polyamide powder. Because of their roughness, these coatings improve the drying in dishwashers. The addition of glass beads furthermore improves the quality of the fluidization.
