ASTM WK81238

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


We continue to have issues with intended weeps and drainage points being sealed shut. The backup of water in this scenario overtakes the attachment flange and eventually leads to sheathing/framing damage. Perhaps the best way to change the behavior of those sealing and painting is to be more clear in our standard about inhibiting drainage.
