    Revision of C1063 - 17a 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 - 21

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



    WK60515


    Keywords

    ceiling; expansion control joints; lath; plaster; screed; suspended ceiling; walls;;

    Rationale

    1.Former WK43401 (the deletion of C926 A2.2.2) was previously withdrawn in Nov 2013 because the task group believed it should remain until similar language was crafted for C1063. This ballot item provides that language. 2.The TG felt that the topic of existing C926 Paragraph A2.2.2 regarding the soffit drip best belongs in C1063, as soffit drips are a part of the lath installation, not the plastering installation. 3.In further development to add clarity, the TG proposes revising the current C926 word exterior to weather-exposed because not every exterior soffit corner is weather-exposed to require a means of drainage, and for including the definition of weather-exposed surface verbatim from the ICC model building code.
