With your gloves and goggles on, inspect your fireplace. If you have a section or multiple sections of your stone veneer fireplace that have become broken or loosened, it is necessary to remove the stone molding to determine if the underlying metal lath has been ripped or pulled out completely. If the lath is damaged, it will be necessary to do a complete replacement.

To remove mortar from the damaged areas, you will need to use your hammer and chisel. Carefully place the chisel against the mortar and hammer skillfully to loosen the mortar without disturbing neighboring pieces of stone. Dispose of the chunks of mortar to keep area free of debris.
Step 3 - Expose Metal Lath
Use the wire brush to brush away excess debris from the chiseled mortar. Carefully examine the lath to determine if it is in good repair. Gently rub your gloved hand across the surface of the lath. If it does not give a rough feeling, the lath will need to be replaced.
Step 4 - Replace Metal Lath
Remove old lath from the wall and clean the area by brushing away dust and debris with your metal brush. Once the area is clean, you can cut the new lath to the same dimensions as the old lath. Nail the new lath into place and spread mortar 1/2 inch thick with your trowel. Allow the mortar to dry completely. Once the mortar is dry, you can add ridges to it with the edge of your trowel. This will improve adhesiveness of the new stone veneer mold.
