What happens here

Once the metal frame is complete, it's time to clad it with cement backer board. Measure and mark the cement backer board panels for cutting. Use a utility knife and a straight edge to score the board, then snap it to size. For larger, more precise cuts, especially for appliance openings, use a circular saw with a diamond blade. Attach the cut backer board panels to the metal frame using cement board screws and an impact driver. Ensure all edges align and create a flat surface for the stone veneer.

Goal: Cover the metal frame with a sturdy, weather-resistant surface.
