ABSTRACT:
An extremely light-weight, portable floating power vibratory concrete "Wet Screed", which is hand operated by a single finisher in order to strike off, tamp and smooth freshly poured concrete using only perimeter slab forms or curbs. The unique angular design of the enclosed hollow screed blade allows the operator to lower the handle and effectively use the rear 60 degree angled surface of the screed blade to cut down the height of the concrete to the desired grade, or raise the handle to effectively use the front 60 degree angled surface of the screed blade to float and maintain the desired grade. The flat aluminum bottom extending from the front angled surface to the rear angled surface of the screed blade functions to produce a smooth, near final finish while the vibratory action tamps the rock down and works the fat to the concrete surface, thereby substantially increasing the finishing time while making the finisher's job much easier. With the new invention, it is possible to "Wet Screed" and then finish, in one day, twice the amount now possible by hand and with less labor.
