How to Repair Stone Veneer: 7 Simple Steps

1. Assess the Damage

Start by closely inspecting the affected area. It is usually possible to fix small cracks or loose stones on your own, but if you are dealing with larger areas or structural damage, you should hire an expert.

2. Gather the Right Tools & Materials

To repair, you will need: 

  • Chisel & hammer
  • Wire brush
  • Masonry trowel
  • Mortar mix (type N or S)
  • Stone veneer adhesive (for reattaching loose stones)

3. Remove Damaged Stones & Mortar

Use a chisel to remove any loose stones gently. Be careful not to damage the surrounding ones. Next, use a wire brush to remove any remaining mixture so that the surface is ready for fresh mortar.

4. Prepare the Surface

Make sure that the surface behind the stone veneer (the substrate) is still intact. It’s essential that the surface is in good condition before you begin applying new mortar. Lightly dampen the area to help the mortar adhere more effectively.

5. Apply New Mortar

Then mix the mortar until it has a peanut butter-like consistency. It should be thick enough to hold but easy to work with. Spread a layer of it on the back of the replacement stones and press them firmly into place. You can use a pointing trowel to smooth out the joints between the stones.

6. Clean & Finish

Use a damp sponge to remove any excess mortar before it dries. Now, wait for 24-48 hours for the mortar to cure. It’s important to resist the urge to touch or disturb the area while it’s curing to ensure a solid bond.

When to Call a Professional

Here are a few signs it’s time to call in the pros:

  • Large sections of loose veneer
  • Water damage behind the stones
  • Significant structural instability
