How to Install Stone Veneer on an Interior Wall

Stone interior veneer can help you remodel your home inexpensively. It is made from a mixture of cement, organic materials and pigments which are placed into moulds to harden. This produces a lightweight material that closely resembles real stone. The stones are attached to a panel that you install on the wall. This allows you to create a natural atmosphere indoors. The beauty of interior stone veneer is that it is much lighter to handle which helps make installation easier. You can install stone veneer indoors with the help of the guide below.

Materials Needed

  • Stud finder
  • Pencil
  • Cement board
  • Screwdriver
  • Wood screws, 1 ¼ inch
  • Cement mortar mix
  • Bucket
  • Wooden stick
  • Notched trowel
  • Saw, with masonry blade
  • Hammer
  • Chisel
  • Putty knife
  • Rubber mallet
  • Tape measure
  • Damp rag
  • Nylon brush
  • Vacuum

Step 1 – Mark Studs and Attach Cement Board

Slide your stud finder across the wall. Mark the location of studs with a pencil as you detect them.

Place a cement board at one corner of the wall to be covered. Use a screwdriver to drive screws through the board, into the studs behind. Allow 8 inches between the screws. Attach cement board onto the rest of the wall.

Step 2 – Apply Mortar onto Board

Follow the instructions to prepare mortar. Use the smooth end of your trowel to spread a thin layer of mortar, about 1/8 of an inch, onto the board. Allow about 1 hour for the mortar to harden. Before it dries up completely, use the notched end of your trowel to create lines on the mortar. This will make sure that the stone veneer is properly set.

Step 3 – Attach Veneers

Apply about ¼ inch of mortar onto the back of a panel. Firmly attach the panel onto the cement board at the top of the wall. Gently tap the veneer on the surface with a rubber mallet to facilitate proper attachment. Clear excess mortar around the edges with a putty knife. Take another panel and attach onto the cement board in the same manner. Continue in this way until the entire wall is covered.

Step 4 – Borders

As you get to the edge of the wall, it may become necessary to cut a panel to fit into place. Use a saw with masonry blade to cut a strip of panel to fit into the space. Attach the panel onto the cement board. For corners or awkward gaps, use a hammer and chisel to cut out individual stones for attachment. It should take about 24 hours for the mortar to set.

Step 5 – Grout

Prepare additional mortar to be used as grout. Place the mortar in a grout bag. Fill the joints between the panels and inside any gaps. Use your putty knife to smooth the grout lines. Allow the grout 24 hours to dry completely. To finish, brush the veneer with a nylon brush. This helps to clear loose mortar from the panels. Use a vacuum to clear dust and loose debris from the floor.
