ASTM WK39189

    Revision of C1063 - 12a Standard Specification for Installation of Lathing and Furring to Receive Interior and Exterior Portland Cement-Based Plaster

    (What is a Work Item?)

    Active Standard: C1063 - 14d

    Developed by Subcommittee: C11.03 | Committee C11 | Contact Staff Manager


    1. Rationale

    Multiple proposed revisions including - that it appears that C1063 doesnt specify galvanizing for screws. In reading Section 6.7.1 and 6.7.2 it appears to say galvanized nails are required, but that no corrosion resistance is required for screws. We need to be consistent here and have galvanizing listed on the screw as well. To keep this wording format consistent with the rest of the section that had been modified in previous ballots. Add E footnote to Table 3. These spacings are based on unsheathed walls. Ribbed lath shall no be used over sheathed walls or solid vertical surfaces.
