What is Stone Cladding?

Stone cladding is the process of covering a wall surface with natural or artificial stone to enhance its appearance and strength. It can be applied to concrete, brick, or even metal surfaces using adhesives, mortar, or mechanical fixings.

Key Features of Stone Cladding:

• Durable and weather-resistant
• Enhances insulation and soundproofing
• Available in various textures, colors, and styles
• Low maintenance compared to painted surfaces

Benefits of Stone Cladding

Benefit	Description
Aesthetic Appeal	Provides a luxurious and natural look
Durability	Resistant to harsh weather and external elements
Low Maintenance	Requires minimal cleaning and upkeep
Energy Efficiency	Offers thermal insulation, reducing heating and cooling costs
Increased Property Value	Enhances curb appeal and resale value

Types of Stone Cladding

1. Natural Stone Cladding

• Granite
• Slate
• Sandstone
• Limestone

2. Manufactured Stone Cladding

• Concrete-based stone veneer
• Polymer-based stone panels

3. Dry Stone Cladding

• Uses no mortar, giving a traditional and rustic appearance.

Materials and Tools Required

Materials:

• Natural or manufactured stone cladding
• Cement-based adhesive or mortar
• Water-resistant primer
• Metal lath (for non-masonry walls)
• Sealer (optional for extra protection)

Tools:

• Trowel
• Masonry saw or angle grinder
• Spirit level
• Tape measure
• Mixing bucket
• Wire brush

Step-by-Step Guide on How to Stone Clad an External Wall

Step 1: Prepare the Wall Surface

• Clean the wall thoroughly to remove dirt, grease, or old paint.
• If the wall is non-masonry (e.g., wood or drywall), install a metal lath for better adhesion.

Step 2: Apply a Scratch Coat

• Mix and apply a mortar layer about 10mm thick using a trowel.
• Score the surface with a wire brush for better grip.
• Allow the coat to dry for 24 hours.

Step 3: Apply the Adhesive

• Use a cement-based adhesive suitable for stone cladding.
• Spread the adhesive evenly on both the wall and the back of the stone.

Step 4: Start Installing the Stones

• Begin at the bottom and work your way up.
• Press each stone firmly into place and use spacers for even gaps.
• Use a level to ensure a straight alignment.

Step 5: Fill the Joints

• Once the stones are set, fill the gaps with grout or mortar.
• Use a pointing trowel to smooth out excess material.

Step 6: Seal and Finish

• Apply a stone sealer for added durability and water resistance.
• Clean off any mortar residue and let the wall cure for 48 hours.

Common Mistakes to Avoid

1. Skipping Surface Preparation – Leads to weak adhesion and stone detachment.
2. Using the Wrong Adhesive – Not all adhesives are suitable for external conditions.
3. Improper Spacing – Can cause uneven patterns and structural weakness.
4. Not Using a Sealer – Reduces the lifespan of the stone cladding.
5. Ignoring Weather Conditions – Installing during extreme temperatures may impact bonding.

Maintenance Tips for Stone Cladded Walls

Maintenance Task	Frequency
Cleaning with mild soap and water	Monthly
Checking for loose stones or cracks	Every 6 months
Applying sealant for extra protection	Every 2 years
