When installing masonry veneer around openings, which component is installed first?

• A. Veneer anchors.
• B. Weep tubes.
• C. Veneer.
• D. Backing wall and flashing.

Answer: (D)

Starting with a solid, moisture-controlled substrate is essential. The backing wall provides the structural backing for the veneer, while flashing creates a continuous water-shedding and drainage path at the opening. Placing these elements first establishes a secure surface for attaching the veneer and a defined route for any moisture that penetrates the veneer to exit, protecting the structural wall behind it. Once the backing and flashing are in place, you can install veneer anchors to tie the veneer to the substrate, then set the veneer itself around the opening. Drainage components like weep tubes are added into the cavity as designed to allow any trapped moisture to escape. In short, the backing wall and flashing set up the system for proper attachment and moisture control, making them the first installed around openings.
