Abstract: An adjustable cement finishing tool including a generally planar float; a rigid mounting bracket coupled to an upper extent of the float; a swiveling member pivotally coupled to the mounting bracket; and a generally elongated arm with a central axis coupled to the swiveling member, and wherein rotating the arm in one direction about its central axis allows it to become engaged with the swiveling member to thereby preclude pivotal movement of the float, and wherein rotating the arm in an opposite direction about its central axis allows it to become disengaged from the swivelling member and thereby allow pivotal movement of the float.
