ASTM C1063-18b is the Standard Specification for the Installation of Lathing and Furring to Receive Interior and Exterior Portland Cement-Based Plaster. It outlines the minimum technical requirements for installing lath and furring systems that support cement-based plaster applications, as specified in ASTM C926. The standard addresses installation practices for both interior and exterior settings, ensuring proper attachment methods, spacing, and support to achieve desired performance outcomes such as fire resistance and sound control. Notably, in 2018, ASTM C1063 was revised to focus solely on installation requirements, while material specifications for lathing accessories and fasteners were relocated to ASTM C1861, streamlining the standards for clarity and usability.
