摘要:
A combined stair screed and float device for quickly and efficiently spreading and smoothing wet concrete comprising a generally shoe shaped member with a vertically and horizontally adjustable top guide and base bar to rest on riser forms. In operation, a user rests the top guide and the base bar on two riser forms with a pointed corner finder floating over the concrete at the desired corner position. The user grasps a grip portion and a handle and guides the device across the tread in a simultaneous screed and float step preparing a smooth surface for finishing. The device is both vertically and horizontally adjustable to accommodate a full range of conceivable step heights, tread lengths, toe kick overhang lengths, and corners.
