ABSTRACT:
A concrete grading tool for grading, leveling and sealing wet concrete is shown and described. The grading tool is comprised of a grading head which is made of a lightweight material such as aluminum and has a long handle extending outward therefrom. The grading head of the present invention is designed such that it floats on top of the wet concrete. It has a triangular design and is substantially hollow therethrough. All three sides are kept at a minimal thickness. On the rearward facing surface is located an attachment block which threadably receives the handle. The handle has a first and a second support member angled downward and also attached to the grading head for additional support of the handle away from the centermost portion. The grading tool allows the user to rake, level, screed and place a precise finish on wet concrete.
