Stone Veneer on Curved Surfaces
Share
Manufactured stone veneer is a versatile and visually appealing material that can enhance various architectural features, including curved surfaces. Whether you're accenting a fireplace, an arched entryway, or a rounded column, installing stone veneer on curves requires special techniques to ensure a seamless and professional look. In this guide, we'll walk you through the key steps and considerations for achieving a flawless curved installation.
Choose the right stone veneer
Before starting your project, select a manufactured stone veneer that complements your design. Some styles and shapes, such as smaller, more irregular pieces, are easier to fit on curved surfaces compared to larger, uniform stones.
Prepare the surface
Proper surface preparation is essential for a strong and durable installation. The steps include:
1. Clean the surface: ensure the substrate (e.g., concrete, wood, or drywall with proper backing) is clean and free of debris.
2. Install a weather-resistant barrier (WRB): apply a moisture barrier if required, especially for outdoor installations.
3. Attach metal lath: secure galvanized metal lath with corrosion-resistant fasteners if installing over plywood or drywall.
4. Apply scratch coat: spread a layer of mortar (follow the manufacturer's instructions) over the lath and score it with a notched trowel to create texture for better adhesion.
Dry fit and cut the stones
Before applying mortar, arrange the stones on a flat surface to determine their placement. Since curved surfaces require tight-fitting pieces, you may need to trim some stones:
1. Use a masonry saw or grinder: to achieve precise cuts, use a wet saw with a diamond blade or a grinder for small adjustments.
2. Vary the sizes: mixing stone sizes and shapes can help create a natural flow along the curve.
Apply mortar and install the stone
Now it's time to attach the stone veneer to the curved surface:
1. Back butter each stone: apply a generous layer of mortar to the back of each piece to ensure a strong bond.
2. Press firmly into place: start from the bottom and work upward, pressing each stone firmly against the scratch coat.
3. Adjust as needed: rotate and adjust stones slightly to fit the curvature and minimize gaps.
4. Use spacers (optional): spacers can help maintain even gaps between stones.
Fill gaps and tool the joints
If your design includes visible joints, use mortar to fill any gaps between stones:
1. Use a grout bag: squeeze mortar into the joints for a controlled application.
2. Tool the joints: once the mortar starts to set, use a jointing tool to smooth and shape the seams for a polished look.
3. Brush away excess: after the mortar dries slightly, use a soft brush to remove loose particles and refine the finish.
Seal and protect the surface
Applying a sealer can help protect your stone veneer from moisture and staining, especially in high-traffic or exterior areas. Choose a breathable sealer designed for manufactured stone and apply it according to the manufacturer’s instructions.
