Any concerns with this application of Thin Brick over DensGlas over steel studs in the SouthEast US? ---

How are you attaching the thin brick to the DensGlass? In the southwest, we scratch & brown with plaster, and stick the brick on the brown coat. We use 1/2" plywood or DensGlass behind the stucco depending on the fire rating or structural (sheer) requirments, and sometimes both. ---

I recall a thin brick veneer at a project in Toledo where children discovered that if they threw a baseball at the wall, the thin brick would pop off. If your building is going to be exposed to such exuberance you may want to have a sample panel to challenge with your fastball. ---

Per Richard’s comment, DensGlass alone may have too much “give” spanning between the studs allowing a stiff veneer brick to pop off. Nathan mentions plywood as a stiffer backing. Another option is cementitous backer boards over the DensGlass. ---

Dens-glass isn’t approved by GP for “adhered” installations. If you want to install the thin brick over dens-glass I recommend, from inside out: Dens-glass, weather barrier (similar to Grace permabarrier), lath with paper backing, scratch/brown coat, than thin set the mortar to the brown coat. ---

Yes, Robin’s post is much more specific and is the system I was inferring. I was being overly generic. As for backing…it depends on the project and the developer’s willingness to invest in durablity. On the low end, I have seen thin brick applied over lath/stucco only, without any other backing between 16" OC studs in some housing applications. The weight and profile of the brick is a factor also, and how it’s capped (such as with a full brick soldier course or precast or similar) ---

Irrespective of the backing, it is critical to specify that the thin brick be fully back-buttered when installed. Many, if not most, of the thin brick delamination failures I have seen are due to insufficient mortar adhesion due to notched trowel application, air bubbles, and voids in the mortar. ---
