Why Use Lime Pointing on Traditionally Built Buildings in Edinburgh
Lime pointing is crucial for the preservation and restoration of traditionally constructed buildings, especially in areas like Edinburgh, known for its historic architecture. Here’s why lime mortar is the preferred choice:
Benefits of Lime Pointing
Breathability
- Lime mortars allow buildings to ‘breathe’, preventing moisture from being trapped within walls. This reduces the risk of dampness and internal decay, unlike modern OPC mortars, which are nearly impermeable.
Flexibility and Compatibility
- Lime mortar is more flexible than cement-based alternatives, making it ideal for historic structures that require more adaptability in materials to accommodate natural movements and thermal changes.
Heritage Preservation
- Lime pointing maintains the authenticity and character of traditional construction methods, ensuring restoration efforts remain true to the building’s original heritage.
Why Cement Pointing is Less Suitable
Moisture Trapping
- Cement pointing traps moisture, accelerating the decay of stone through frost action and salt concentration.
Chemical Reaction and Erosion
- Cement-rich mortars set harder than stone, causing moisture to evaporate at the stone surface, leading to rapid weathering and stone damage.
Aesthetic and Structural Disparity
- Cement mortar often clashes with the color and strength of traditional stonework, appearing out of place and too robust for masonry units.
Cost-Effectiveness
- Although initially cheaper, cement pointing is more prone to damage and moisture issues, resulting in higher long-term maintenance costs. Lime pointing offers durability and reduces frequent repair needs, making it a more cost-effective solution over time.

Frequently asked questions about lime pointing
Lime mortar is more breathable than cement, allowing moisture to escape from the walls of historic buildings. This prevents dampness and decay. Lime is also more flexible and compatible with older structures, accommodating natural movements without cracking. Moreover, it helps preserve the building’s original appearance and character, staying true to traditional construction methods
Lime pointing supports the structural integrity by allowing the walls to move naturally without cracking. Its breathable nature prevents moisture build-up, reducing the risk of freeze-thaw cycles that can damage masonry. Lime’s compatibility with older materials ensures that the restoration process does not introduce stresses that could compromise the building.
While lime pointing may have a higher initial cost due to the materials and expertise required, it is more cost-effective in the long run. Lime’s durability and ability to prevent moisture-related issues mean fewer repairs and maintenance, ultimately saving money over time
Lime mortar is suitable for most types of historic masonry buildings. However, it is essential to assess the specific needs of each structure, as certain conditions may require tailored mixtures or techniques. Consulting with a conservation specialist is recommended to determine the best approach.
Lime pointing can last several decades if applied correctly, often outlasting cement pointing. Its ability to prevent moisture damage and accommodate natural building movements contributes to its longevity. Regular maintenance and inspections can further extend its lifespan.

Key Considerations for Lime Pointing vs. Cement Pointing in Edinburgh
When assessing building maintenance in Edinburgh, particularly for historic structures, understanding the differences between lime and cement pointing is crucial. Here are several factors to consider:
Common Issues with Cement Pointing
- Stone Erosion: Hard cement pointing often leads to stone erosion due to its impermeability.
- Damaged or Missing Pointing: Look for loose or missing pointing on stonework, which may indicate damage.
- Saturated Stonework: Cement pointing prevents evaporation, causing moisture to saturate the stone.
- Lack of Flexibility: Cement-based materials are rigid, leading to cracks and fractures as they cannot accommodate the natural movement of stone structures, potentially compromising structural integrity.
Recommended Repair Solutions
- Selective Repointing: Use traditional lime pointing in Edinburgh to selectively repoint masonry units.
- Cement Removal: Carefully remove existing cement pointing and replace it with lime mortar.
Advantages of Lime Pointing
- Porosity and Breathability: Lime mortar is more porous than cement, allowing buildings to breathe and moisture to evaporate naturally.
- Flexibility: Lime accommodates minor movements in structures, reducing the risk of cracks and preserving masonry integrity.
- Compatibility with Historic Materials: Historic buildings often feature soft masonry units. Lime mortar is weaker than the stone, meaning it will crack instead of the masonry, preserving the building.
Considerations for Lime Mortar Application
- Setting Time: Non-hydraulic lime takes longer to set and should not freeze before setting fully.
- Drying Regulation: Ensure lime mortar dries at a slow rate to prevent shrinkage cracks. Protect it from direct sunlight and wind using damp hessian to maintain optimal drying conditions.

WHAT IS THE PROCESS
Our Edinburgh team will check your stone wall or stone and brick wall to have a closer inspection of the existing mortar
Then we can send your edinburgh lime to the Scottish Lime Centre for a closer inspection to try and find the based mortars type for a additional fee of £980+vat, this allows you to tray and match the existing as close as possible
Then we can use traditional methods to replace your mortar with new lime
