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.
