    The language in A2.3.2 has been successfully revised and approved for insertion of ASTM C1063 where it is more appropriate. For reference, ASTM C1063 reads as follows: Where solid base materials interface with framed, or framed and sheathed base materials and are to receive a continuous coat of plaster, lathing accessories to reduce cracking, to facilitate drainage, or both, as categorized in Specification C1861, shall be installed at the interface of these base materials. Omission of these accessories shall be permitted provided the contract documents require provisions that are equivalent in function and performance to control cracking and facilitate drainage, or both. The C926 and C1063 task groups agreed that when appropriate language was developed and inserted in C1063, the existing language in C926 can be deleted. This ballot item removes the old language from C926.
