Lime Mortar vs Cement: What’s the Difference?
When it comes to masonry and repointing, choosing the right mortar is essential for the longevity and integrity of your property. Many property owners often debate lime mortar vs cement, but understanding their differences can help you make the right choice for your building. At Evans Repointing and Brickwork, we specialise in using the best materials to restore and maintain brickwork, ensuring that your property remains strong, durable, and in excellent condition.
What is Lime Mortar?
Lime mortar is a traditional masonry mortar made from lime, sand, and water. Unlike modern cement-based mortars, lime mortar is more flexible and breathable, making it ideal for older and heritage properties. Because it allows moisture to escape, it helps prevent issues like dampness, salt deposits, and cracking, which can often occur in older structures when cement is used.
Benefits of Lime Mortar
- Breathability: Lime mortar allows moisture to move through the wall, reducing the risk of trapped dampness.
- Flexibility: Unlike rigid cement, lime mortar can adapt to natural building movements, preventing cracks.
- Eco-Friendly: Lime mortar has a lower carbon footprint compared to cement and is a more sustainable building material.
- Heritage Preservation: Many historical and listed buildings require lime mortar for repointing to maintain authenticity and structural integrity.
- Self-Healing Properties: Lime mortar can naturally reabsorb carbon dioxide, which aids in repairing minor cracks over time.
What is Cement Mortar?
Cement mortar is a modern mixture of Portland cement, sand, and water. It is widely used for new builds due to its quick-setting nature and high strength. However, for older buildings, cement can create long-term problems due to its lack of breathability and rigidity.
Drawbacks of Cement Mortar
- Traps Moisture: Unlike lime mortar, cement does not allow moisture to escape, which can lead to damp and structural issues.
- Rigidity: Cement is less flexible and does not accommodate natural movements in older buildings, leading to cracks and damage.
- Can Damage Historic Brickwork: The hardness of cement can cause bricks in older buildings to crack and erode over time.
- Environmental Impact: Cement production has a high carbon footprint compared to lime mortar, making it a less sustainable choice.
Lime Mortar vs Cement – Which One Should You Use?
When considering lime mortar vs cement, the choice depends on the type of building you are working with:
- For Historic or Heritage Buildings: Lime mortar is the best choice due to its breathability, flexibility, and historical authenticity.
- For Modern Construction: Cement mortar is commonly used for new builds and structures requiring higher compressive strength.
- For Restoration Projects: If you are restoring an older building, using lime mortar will ensure that the structure remains intact and avoids long-term issues caused by cement.
