Can You Install Stone Veneer Over Stucco?

If you’re planning a home renovation or exterior upgrade, you might wonder: can you install manufactured stone veneer over stucco? The answer is yes! With the right preparation and materials, stucco provides a stable surface for stone veneer, allowing you to transform plain walls into striking, durable features that elevate your home’s interior or exterior.

Why stone veneer over stucco works

When it comes to installing manufactured stone veneer, the type of substrate, stucco, drywall, or otherwise, doesn’t really matter. The key to a successful installation is properly attaching metal lath and applying a scratch coat over the surface. Stucco provides a convenient base, but it’s the metal lath secured to wall studs and the scratch coat that ensure the stone veneer adheres correctly and remains durable over time. This method creates a stable, long-lasting foundation for both interior and exterior stone applications.

Steps to install stone veneer over stucco

1. Inspect and prep the stucco: begin by ensuring your stucco is in good condition. Repair any cracks or loose areas to create a smooth, stable surface for installation.

2. Install metal lath: apply metal lath over the stucco to provide a secure base for the stone veneer. Make sure the lath is fastened directly into wall studs using corrosion-resistant nails or screws. Securing the lath to the studs ensures the stone veneer will have maximum support and long-term stability.

3. Apply scratch coat: once the metal lath is properly attached, apply a scratch coat of mortar. This layer is essential, giving the stone veneer something to grip and preventing future movement or separation.

4. Set the stone veneer: using quality Type S mortar, press each piece of manufactured stone veneer firmly into the scratch coat, ensuring pieces are level and properly aligned.

5. Grout and finish: after the stone is installed, fill any gaps with mortar or grout to create a polished, seamless appearance.
