This project builds on the basics of working with concrete block and shows you how to begin laying a concrete block wall.
Check the height of the block with your story pole, and push the block down until the top is even with the mark. If the block is low, pull it out, place more mortar on the bed, and replace the block. Then place a level on top of the block and level it along its length and width.
To prepare the second block, set it on end and butter its ears with a downward swiping motion of the trowel. Then press down on the mortar on the inside edge of the ear. This will keep the mortar from falling off when you set the block. If the mortar does fall off, start over with fresh mortar.
