Lathers install the supportive backings on ceilings or walls to which plaster or other materials are applied. Work involves gypsum, composition board and/or wood lathe. The process also includes wall furring, the erection of steel and tying or lacing metal lath on both walls and ceilings.
Workers will identify and use all types and sizes of screeds and beads, and will learn to apply drop hangers, runners, and furring to hang ceilings. They will learn to identify and nail diamond mesh, flat rib, high rib, herring bone, paperback and boswick metal lathe.
