    (What is a Work Item?)

    Active Standard: C926 - 20b

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



    WK71051


    Keywords

    bond; brown coat; cementitious; exterior plaster; fog coat; portland cement; scratch coat; stucco;;

    Rationale

    In two coat work, the first coat is not scratched, as the depth of the scratches will exceed the thickness of the finish coat and telegraph. The proposed revision corrects this error in Section 7.5.3.1 to eliminate the need for scratching in two-coat work.
