A method and device for providing a substrate ( 10 ) with a coating layer ( 13 ) of a polymeric material, comprising the steps: a) a pulverous, polymeric material ( 2 ) is suspended ( 1 ) in a fluid ( 3 ), b) the fluid ( 3 ) is pressurised ( 5 ), c) the pressurised suspension is ejected ( 16 ) onto the substrate ( 10 ) to form the coating layer ( 13 ), d) the polymeric material is, during any one of steps a)-c), heated ( 4, 6, 11 ) to a temperature above its softening temperature.
