Abstract
A concrete finishing apparatus and method for smoothing and flattening partially cured concrete to a close-tolerance surface includes a movable unit which is movable and entirely supported on or over a partially cured concrete surface and at least one rotatable finishing member, such as a cylindrical tube, roller or the like, mounted to the movable unit. The rotatable finishing member is positioned at the partially cured concrete surface and rotatable to engage and finish the surface of the partially cured concrete to a high quality, close-tolerance flat and level concrete floor surface. The rotatable finishing member is preferably rotatable in a direction generally opposite to the direction of travel of the movable unit to enhance the finishing process and to carry any cement paste or residue forward with the finishing member to fill in any low areas as the concrete finishing apparatus moves over the partially cured concrete.
