A method of dispersing fibers in an electromagnetic-attenuating coating and applying the coating to a substrate. The method includes mixing a coating material of fibers and resin in a container such that the fibers are uniformly dispersed in the resin without breaking the fibers. The method also includes feeding the coating material from the container while maintaining the fibers uniformly dispersed in the resin and without breaking the fibers. In addition, the method includes applying the coating material to a substrate. The mixing is carried out by subjecting the container to an oscillatory shaking action, the feeding step is carried out by pressurizing the container and ejecting the coating material through a bottom opening in the container and the applying step is carried out by spraying the coating material on the substrate with an air-nozzle spray gun.
