    1. Rationale

    Backplastering is an obsolete practice for exterior walls because it cannot accommodate the water barrier system required in the ICC code at 1403.2, including the water barrier, means of drainage or condensation control. This revision excludes backplastering in C926 from use as an exterior wall cladding.
