Continue Building the Brick Pattern
Start building up the body of your brick work. As you work, keep the running bond by working from in from the corners where the running bond was established, making sure the end of each brick hits the middle of the brick above and below it.
Once you have some of your brick work established, mark a straight line across the wall using a straight edge and a level. Build a continuous row across the length of the wall to act as a guideline for setting the brick and maintaining the running bond (Image 1); if you have multiple people working on this project, they can then start from opposite ends of the wall and work together without worrying that their running bonds won’t match up.
Step back every now and then to check your work (Image 2). If your wall is long, the row might begin to sway or the joint sizes to change. The joints and line don’t have to be perfect, but there should be some consistency.If a row of brick doesn’t meet up perfectly, i.e. there’s not room for full brick all the way across, you can cut a brick plug to fit, but don’t cut the brick to less than 3/4 of the size of the full brick. If the gap won’t be closed by using a 3/4 brick and adjusting some of the joints, you can cut a second brick about that size and hide these two cut-down bricks in the length of the wall.Once all of the bricks have been attached, you're ready to start grouting.
