How to Install a Ledgestone Fireplace

Sand every part of the surface where the Ledgestone will be installed. Use a stud finder to determine every stud and frame board located behind the wall surrounding the fireplace. Mark the studs clearly on either side of the stud with a bold marker. Drill holes every 12 inches into each stud and every 6 inches along the edges of the section that will have Ledgestone attached to it.

Wrap lath metal mesh around the entire fireplace area. Overlap each section of lath by at least 6 inches. Drill 3-inch wood screws through large plastic disk washers and into each hole, attaching the lath tightly to the wall.

Cover the entire lath section with 1/4 inch of mortar using a trowel. Allow the mortar to dry for three hours. Scratch up the surface with a metal rake, until the entire surface is well covered with scratch marks. Let the mortar dry for 48 hours.

Apply 1/4 inch of mortar to the back of the Ledgestones one at a time. Press them into the wall and hold them in place for 30 seconds before releasing them. Place the stones all over the wall, beginning at the top and filling them in all around the fireplace. Be sure to use fire-resistant stones around the fireplace area. Remove excess mortar.

Let the mortar dry for three hours. Apply grout between the stones to the desired depth for the right overall appearance. Let the grout dry for at least 48 hours before starting a fire in the fireplace.
