TO CUT OR NOT TO CUT: RESOLVING THE DECADES OLD ARGUMENT OF WHETHER OR NOT TO CUT LATH AT CONTROL JOINTS IN PLASTER WALL ASSEMBLIES – EARN AN AIA LU CREDIT!
Since the invention of the stucco control joint in 1955 by Raymond Clark, the control joint has had its share of controversy. Originally designed as a stopping point for plaster application and small stucco movement stress relief, the control joint is now associated with everything from water management to aesthetics. The presenter, along with several industry collaborators, have spent months testing and observing a 1200-square-foot stucco mock-up in an environmentally harsh setting. Based on the initial results to date, the “to cut lath or not cut lath at joints” debate will have to be fueled by something other than cracking. In this session, the presenter will share the process of discovery and how theories were verified and myths dispelled after conducting performance testing that could likely impact future codes related to stucco installation.
- Understand the importance of the substrate and preparation.
- Understand the water management behind the stucco system and the code (as well as referenced standard) requirements for water management.
- Understand proper control joint placement and the benefits of continuous joints (i.e. the need to turn the corner with horizontal joints), as well as the importance of panel size and configuration.
- Understand the significance of proper curing and how to select a finish.
