Create the initial moisture barrier by nailing felt or a waterproof house-wrapping material like DuPont's Tyvek to the wooden exterior wall. If you are applying the veneer over an existing brick or concrete wall, the moisture barrier is not necessary. Attach the lath to the wall using nails or screws with plastic washers to seal out moisture.

Apply the mortar in a single layer between one-sixteenth and one-eighth of an inch thick. Absolute precision is not necessary, but try to make the mortar layer relatively even.

Once the mortar is on the lath, attach the ledgestone veneer flats to the wall. Follow the manufacturer's instructions to ensure a clean, uniform look. However, some gaps or imperfections may remain after finishing the installation. Use scraps or loose pieces of veneer to fill in any gaps.

Despite their name, ledgestone veneers are not made of natural ledgestone. These products are made of molded concrete that simulates natural ledgestone's appearance. Manufacturers paint the concrete pieces while still wet to simulate the color variations of natural ledgestone. Manufacturers use concrete because it is stronger, more durable and much lighter than natural stone.
