An agitator head tailored for mixing a viscous liquid such as driveway sealer or paint has an elongated shape consisting of two arcs which meet at their end points, and a common chord between the two arcs passes through a center of the head. Each arc is radiused to match the radius of a container holding the liquid to be mixed. A plurality of tapered openings in the head permit easy vertical movement through the liquid in the container. Vertical ribs in the head provide the structural strength necessary to withstand the force of agitation and keep the head from breaking.
