Abstract
This specification covers the installation of lathing and furring to receive interior and exterior Portland cement-based plaster. The following materials shall be used: metal plaster bases—expanded metal lath and wire laths; accessories—steel, PVC plastic, zinc alloy, and cornerite; channels—external corner reinforcement and foundation weep screed; wire; rod and strap hangers; clips; fasteners—nails and screws. Hangers and cold-rolled channel main runner shall conform to the allowable spacing and spans, respectively. The following methods are discussed: installation of hangers for suspended ceilings under wood constructions, attachment of hangers to main runners, installation of main runners, installation of cross furring, metal furring for walls, lapping of metal plaster bases, spacing of attachments for metal plaster bases, application of metal plaster bases, and application of accessories.
