Revision of C1787-14(2019) Standard Specification for Installation of Non Metallic Plaster Bases (Lath) Used with Portland Cement Based Plaster in Vertical Wall Applications


The current definition in this standard does not provide users with guidance in terms of common types of materials used to produce non metallic plaster bases which has resulted questions as to whether the standard applies to a particular type of non metallic, all types, etc. The proposed revision provides clarity and includes examples of common non metallic materials in use today. Similar definition changes are also being proposed to other non metallic lath standards (C 1788 and C 1764).
