Revision of C926-21 Standard Specification for Application of Portland Cement-Based Plaster


The existing language in A2.1.3 does not make sense. As it is currently written, the word “or” suggests that edges of plaster panels on the interior of a building would need to be sealed. This ballot item clarifies the intent of A2.1.3 by clearly stating that the requirement for sealing and caulking applies only to exterior applications. Further, the ballot item expands the requirements of sealing and caulking to include separations and penetrations.
