Abstract: The invention provides a device (100) for applying a liquid film to surfaces in an area. The device (100) comprises a head (110) for discharging a flow of liquid droplets (200) in a discharge direction (D). The device (100) is arranged for rotating the head (110) according to two rotational degrees of freedom to move the discharge direction (D) through the area. The device (100) comprises a distance sensor (120) for measuring a distance (d) between the head (110) and surfaces in the area along the discharge direction (D). The device (100) is configured according to at least one of a first and second configuration. In the first configuration a rotational speed of the head (110) is adjustable as a function of the distance (d) measured by the distance sensor (120). In the second configuration a flow rate of the flow of liquid droplets from the head (110) is adjustable as a function of the distance (d) measured by the distance sensor (120).
