Abstract
An improved method and apparatus are provided for resurfacing recreational (e.g., tennis) courts and other surfaces. The apparatus includes self-contained drive means including drive wheels mounted on an elongated frame structure, and additionally supported for rolling movement on a plurality of casters. The apparatus is provided with flexible blade and brush elements for spreading and smoothing court resurfacing material uniformly across the surface. In a forward resurfacing direction, flexible squeegee-type blades, with or without associated brushes, engage the resurfacing material ahead of the device, while flexible brush elements engage the resurfacing material behind the device to erase tracks caused by the drive wheels and casters, and to effect final smoothing and texturing of the resurfacing material. The drive wheels may be moved into and out of ground engaging contact, and a steering device provides for lifting one or the other of the drive wheels out of ground engaging contact. The device is movable in one direction to resurface an entire tennis court in a single pass. In a related aspect, tape is applied over the court boundary lines prior to resurfacing, and removed after resurfacing. Multiple coats of resurfacing material may be applied, in the same, or different directions.
