A tool for use with building block or brick walls consisting of a flexible rubber cavity worn over the index finger of one hand and containing an integral rectangular end with front and rear flat parallel sides. The rectangular end extends downwardly at 90 DEG from the axis of the finger and is placed over the side of a brick when grasped by the hand. The shape of the finger cavity approximates the shape of the finger and contains an irregular lip and depression to maintain a secure fit even when the finger is bent and moved. A method of using the tool involves laying building blocks with adhesive between the blocks.
