Stone cladding can transform plain walls into strong architectural features. Whether used on an interior feature wall or an exterior façade, correct installation is essential for long-term performance and appearance. This guide explains traditional, practical methods for installing stone cladding on both internal and external walls.
Tools and Materials
Materials
- Natural stone cladding panels or split-face tiles
- High-performance adhesive suitable for stone cladding
- Primer (where required)
- Grout or pointing mortar (if joints are used)
- Stone sealer (optional)
Tools
- Notched trowel
- Spirit level
- Tape measure and chalk line
- Tile spacers or wedges
- Rubber mallet
- Wet saw or angle grinder with diamond blade
- Safety equipment
Step 1: Prepare the Wall
Correct preparation is the foundation of any stone cladding installation. The wall must be clean, stable, and capable of supporting the weight of natural stone.
Interior Walls
- Remove loose paint, wallpaper, and dust
- Repair cracks and uneven areas
- Prime smooth or dusty surfaces if required
Exterior Walls
- Check and resolve damp or drainage issues
- Remove loose render, paint, moss, and debris
- Apply a levelling or scratch coat if the surface is uneven
Step 2: Set Out the Layout
Traditional practice is to plan the layout before fixing begins. Proper setting out helps maintain straight lines, balanced joints, and a professional finish.
- Mark level reference lines using a chalk line
- Dry-lay several panels to confirm the pattern
- Start from a strong visual point such as a corner or centre line
Step 3: Choose the Correct Adhesive
Stone cladding requires a strong, flexible adhesive, particularly for exterior walls exposed to weather and temperature changes.
We recommend High Performance Adhesives for Stone Cladding Installation, designed to securely bond heavier stone and provide long-term durability for both internal and external applications.
Apply the adhesive using a notched trowel and follow the manufacturer’s instructions carefully. Full adhesive coverage is essential to avoid voids behind the stone.
Step 4: Fix the Stone Cladding
Begin fixing from the bottom and work upwards. This traditional method helps support the stone as installation progresses.
- Apply adhesive to a manageable area of the wall
- Press each panel firmly into place
- Check alignment regularly with a spirit level
- Lightly tap with a rubber mallet if needed
- Maintain consistent joint spacing where applicable
For exterior installations, work in smaller sections to prevent the adhesive from drying before the stone is fixed.
Step 5: Jointing and Cleaning
Dry Joint Finish
- Common with split-face and stacked stone panels
- Clean off excess adhesive immediately
Grouted or Pointed Finish
- Allow adhesive to fully cure before jointing
- Clean the stone surface before grout haze sets
Step 6: Sealing (Optional)
Sealing is recommended for many natural stones, particularly in kitchens, fireplaces, and exposed exterior areas. A suitable sealer can help protect against staining and moisture ingress.
Best Practice Tips
- Ensure the wall structure can support the weight of stone cladding
- Keep adhesive thickness consistent
- Use proper cutting tools and safety equipment
- Plan corners and edge details carefully
Conclusion
Stone cladding installation rewards careful preparation, correct materials, and a steady, traditional approach. Using the right adhesive is critical to achieving a durable and long-lasting result.
