rough-cut joint, flat joint, flush joint, hick joint

rough-cut joint
The simplest joint in masonry; made by holding the edge of the trowel flat against the brick and cutting in any direction, so that the mortar in the joints is made smooth with the wall surface. Because this cutting action produces a small hairline crack, the joint is not always watertight.
