Lay the corner brick exactly on the point where the corner is located. See Figure 12-28A. The corner brick must be set level and square with the wall line. Cut excess mortar and return it to the mortar board. See Figure 12-28B. 5. Lay the remaining four or five bricks of the lead corner. This is called “tailing out” the lead of the corner. After the bricks have been laid, level them with a plumb rule. After leveling, remove excess mortar and return it to the mortar board. This will help keep the level clean. See Figure 12-29.
