To get an understanding of what’s happening in the lath and plaster industry is largely a function of being in-tune of what’s going on with ASTM committee C11 on Gypsum and Related Building Materials and Systems. The committee, with a current membership of more than 380, has jurisdiction of 57 standards, covers specifications and guides for gypsum products and gypsum board, metal lath, studs, fasteners and related metal products, as well as practices for the application of stucco and EIFS products.
The C-11 committee supports two separate task groups: ASTM C-926-16a (Standard Specification for Application of Portland Cement-Based Plaster) and ASTM C-1063-16a (Standard Specification for Installation of Lathing and Furring to Receive Interior and Exterior Portland Cement-Based Plaster).
