How do you control the grounds (stucco thickness without casing) Additionally, do you need casing to separate dissembler materials?
There is nothing in the code that prevents you from putting in additional casing and control joints. The misconception that we wanted to dispel is that control joints are “required” by the code in direct applied stucco at locations other than where you find control joints in the substrate. I would reinforce the potential leakage problem inherent with all installed stucco joints. Proper detailing of joints is essential for a leak proof stucco coating. As you mentioned there should be a joint at dissimilar materials.
