Revision of C1780-20 Standard Practice for Installation Methods for Cement-based Adhered Masonry Veneer


ASTM C1780 is currently silent on what clearances are required at the bottom of the wall when installing adhered cement-based masonry veneer. The International Building Code (IBC) has requirements for clearances when installing over exterior stud walls. This ballot proposes to include those requirements into ASTM C1780.
