Revision of C1063-20a Standard Specification for Installation of Lathing and Furring to Receive Interior and Exterior Portland Cement-Based Plaster


C1063 Roof-Wall Means of Drainage 1.While it is functionally necessary to drain stucco cladding on exterior walls above lower roofs, balconies and similar conditions, this requirement is not clearly described in ASTM C1063. This ballot item clarifies the need for a weep screed or similarly functional accessory at these conditions. 2.Adding the term means of drainage to 7.4.4, and the new paragraph 7.4.5 describes the functional purpose of the foundation weep screed specifically, and as more broadly applicable to other permitted means of drainage such as the designated drainage screed, matching the terminology found in C1063 and C1861.
