Revision of C1063-23 Standard Specification for Installation of Lathing and Furring to Receive Interior and Exterior Portland Cement-Based Plaster

Rationale

Section 7.4.10. addresses control joint placement in both walls and ceilings; however, the noted text is creating confusion for standard users who question how the phrase “length and width” is applied to a wall. Simply put, while the “length” of a run of a wall can be logically determined, what constitutes the “width” of a wall is unclear.
The proposed change modifies 7.4.10.3. to eliminate the length and width phrase. In so doing, it clarifies that the language applies to a plaster panel regardless of whether it is on a ceiling or a wall.
