flush-cut joint

In brickwork, a masonry joint in which an excess of mortar is applied; then a trowel is held flat against the brick surface and moved along the surface, so as to cut away the excess mortar. The resulting joint is flush with the wall, and is usually not watertight as a result of small hairline cracks produced by the cutting action as the trowel removes the excess mortar.

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.
