A powder coating station (1) for electrostatic coating of a first and second side of a work piece 3 moved relative to the coating station (1) comprises at least a first dispensing unit (4, 5) for dispensing coating particles and at least a first electrode arrangement (6, 7, 8, 9) for influencing the coating of the work piece (3) through modification of the field line pattern in the edge regions of the side 3a. A method for coating a first and second side of the work piece (3) comprises the steps: Provision of an arrangement (1) of at least one dispensing unit (4, 5) and at least one electrode arrangement (6, 7, 8, 9) which has at least one electrode and which is assigned to the dispensing unit (4, 5); movement of the work piece (3) relative to the coating station (1) along a path past the arrangement (1); dispensing of a coating composition for coating the work piece (3) during the relative movement of the work piece (3); and application of a positive or negative voltage and/or charge at least during a partial period of the coating process, while the dispensing unit (4, 5) is polarized with a polarity different from that of the electrode arrangement (6, 7, 8, 9).
