    Abstract

    This specification covers welded wire lath, flat or self-furring, with or without backing, designed for use as a base to receive Portland cement-based interior plaster and exterior stucco. Welded wire lath shall be fabricated from cold-drawn, galvanized steel wire, conforming to the referenced specification. The wire shall be zinc-coated and the backling shall be attached to the lath to prevent accidental removal during shipping, handling, or installation. The thickness of the embedment of the lath and plaster shall be measured from the back plane of the back wire, exclusive for furring, to the backing or surface of the substrate.
