Stone masons.

For the purpose of the Washington state public works law, chapter 39.12 RCW, stone masons shape and set stone blocks to build stone structures, such as piers, walls and abutments, and lay walks, curbstones, or special types of masonry, such as alberene (acid-resistant soapstone) for vats, tanks, and floors, using mason's tools.
The work includes, but is not limited to:
• Shaping stone blocks preparatory to setting, using chisel, hammer, and other shaping tools.
• Spreading mortar over stone and foundation with trowel and setting stone in place by hand or with the aid of a crane.
• Aligning stone with plumbline and finishing joints between stone with a pointing trowel.
• Spreading mortar along mortar guides to insure joints of uniform thickness.
• Cleaning surface of finished structure and removing mortar, using muriatic acid and brush.
