Use antique brick for outdoor patios and fireplaces. The brick in the courtyard came from buildings that were torn down in Pine Bluff, Arkansas. “The biggest problem with antique brick is there are several different sizes and it tends to get mixed up. That can make it tough to lay out a patio,” Gary says. Cathy recommends setting the brick in sand, rather than concrete, to give a relaxed and aged look. Plus, the sand helps level odd-size bricks.
