A method and apparatus for coating a paper or board web or the like (,) using a coating mix aerosol generated by means of an ultrasonic atomizer. The output power of a plurality of ultrasonic transducers (,) disposed proximate to a surface of the moving web (,) is passed via a vibrated beam (,) to a coating mix flow (,) flowing proximate to the web (,). Ultrasonic vibrations applied to the coating mix atomize the upper layer of the coating mix flow into an aerosol (,) which is emitted toward the web (,) and adheres thereto.
