Waterline
While sand is used as a release agent in the hand-molding process to allow the molded clay to be easily released from the mold, water is used in the water-struck process. This creates a characteristic water-struck surface with an individual, sometimes rough appearance.
The surface of water-struck bricks is smoother than that of hand-molded bricks. Genuine water-struck bricks are used in the construction of single- and multi-family homes, in the renovation of old buildings, and above all as architectural bricks in development projects.
