  • Patent number: 6779945
    Abstract: An apparatus for leveling and smoothing a substance such as concrete and drawing up paste in one motion. The apparatus has a leveling blade with a straight edge and a smooth-surfaced float. The float attaches to the leveling blade by a connecting strip of resilient material, which permits the position of the float to contour to the concrete surface. The connecting strip, adjacent to the float, contacts the concrete surface to pull up cement paste, which creates a more workable surface. The leveling blade attaches to the handle by a mount. The mount and handle are adjustable to add additional length to the apparatus for use on various sized concrete surfaces. A vibratory mechanism can also be attached to the apparatus to assist in leveling and smoothing concrete.
