Different Types of Stone Cladding and Removal Approaches

Not all stone cladding is created equal. Different types require specific removal techniques to effectively separate them from the underlying brickwork. This section examines the most common types of stone cladding and the best approaches for removing each.

Natural Stone Veneer

Natural stone veneer consists of thin slices of actual stone adhered to the wall surface.

Characteristics:

• Heavy (typically 10-15 lbs per square foot)
• Irregular shapes and thicknesses
• Usually attached with mortar and sometimes mechanical fasteners
• Extremely durable bond

Removal Approach:

1. Begin at joints between stones where the mortar is exposed
2. Use a hammer and chisel to break the mortar bond around each stone
3. Work a masonry chisel behind the stone at multiple points
4. Apply leverage using a pry bar once the bond is weakened
5. For large stones, have a helper support the weight as it comes free
6. Expect significant adhesive residue requiring extensive cleanup

Special Considerations:

• The substantial weight creates strong bonds requiring more force
• Risk of damaging brickwork is higher due to removal force needed
• Consider cutting larger stones into manageable sections with an angle grinder

Manufactured Stone Veneer

Manufactured (or cultured) stone veneer is made from concrete molded and colored to resemble natural stone but is typically lighter.

Characteristics:

• Moderate weight (7-10 lbs per square foot)
• More uniform thickness than natural stone
• Usually attached with specialized adhesive
• May include wire mesh or metal lath underneath

Removal Approach:

1. Locate and cut through any metal lath with tin snips
2. Use a hammer and wider chisel to separate veneer from adhesive
3. An oscillating multi-tool with a scraper attachment works well between layers
4. Once sections begin to separate, use leveraged force with a pry bar
5. Remove any remaining mesh or lath after the veneer is removed

Special Considerations:

• More brittle than natural stone and likely to break during removal
• May have a waterproof membrane behind it that should be completely removed
• Often installed with scratch coat that needs separate removal

Brick Slip Cladding

Brick slips are thin sections of brick applied to give the appearance of full brickwork.

Characteristics:

• Uniform size and thickness
• Typically attached with specialized adhesive
• Often installed with precise spacing to mimic traditional brickwork
• Relatively lightweight compared to stone options

Removal Approach:

1. Target the mortar joints between slips with a narrow chisel
2. Work the chisel behind individual slips to break the adhesive bond
3. Use a hammer drill with a chisel attachment for faster removal
4. After removing slips, focus on the adhesive layer which is often more stubborn

Special Considerations:

• Modern adhesives used with brick slips can be extremely strong
• May come off in small pieces rather than whole units
• Often installed over backer board which may need separate removal

Panel-Based Stone Cladding

Some stone cladding comes in larger panels that interlock, especially in more recent installations.

Characteristics:

• Large uniform panels (often 1-4 square feet each)
• Mechanical fastening system at edges
• May have interlocking edges or overlap design
• Often installed with foam backing for insulation

Removal Approach:

1. Identify the fastening system (usually visible at panel edges)
2. Remove screws or clips securing the panels
3. Work from top to bottom, removing entire panels when possible
4. Address the subfastening system separately after panels are removed

Special Considerations:

• Look for hidden fasteners under trim pieces or at panel overlaps
• Foam backing may come off with panels or require separate removal
• Modern systems may have integrated moisture barriers that should be fully removed

Mortar-Set Stone Facing

Traditional stone facing set in thick mortar beds requires a different approach.

Characteristics:

• Irregular stones set in thick mortar
• No standard pattern or size
• Extremely strong bond to substrate
• Often quite old (pre-1960s installations)

Removal Approach:

1. Use a hammer drill with masonry bit to create pilot holes in mortar joints
2. Switch to chisel attachment to expand these weakened areas
3. Work from multiple angles to loosen each stone
4. Expect significant mortar residue requiring power tool removal
5. Progress slowly to minimize damage to underlying brickwork

Special Considerations:

• May be integral to the wall structure in older buildings
• Can be extremely difficult to remove cleanly
• Consider professional assessment for heritage properties
