All lime mortars should be left overnight to allow excess moisture to be drawn out of them. Once they have removed this excess moisture, they shrink and can then be compacted into the joint. Hydraulic lime (N, H, L’s) require aftercare; the hydraulic mortar needs to be hydrated regularly for a minimum of two weeks or up to 6 months; this should be done at least three times a day. Hydrating the hydraulic mortar must be done to enable the mortar to be completely set. Non-hydraulic limes take longer to set but require little to no aftercare. Non-hydraulic limes carbonate over time and can take 12 months or longer to fully carbonate. However, non-hydraulic limes do not need to fully carbonate to offer protection against the elements and pozzolans are added to make them more durable where required.

Traditional Building in Yorkshire Built From Lime Mortar
The traditional buildings in Yorkshire are some of the most iconic in England. These buildings were constructed using traditional hot mixed lime mortars. A technique passed down through generations of stonemasons.
In the early days of the Industrial Revolution, lime was used extensively in construction due to its solidity and durability. It was also breathable, allowing moisture to evaporate and preventing dampness from building up inside buildings.
However, the First World War outbreak led to a massive loss in skilled labour. The need for rapid rebuilding meant that cement became the material of choice. While this allowed construction to continue rapidly, it also led to a decline in the quality of vernacular architecture.
Today, efforts are to revive the use of lime mortars and hot lime pointing to preserve the unique character of Yorkshire’s buildings. Using lime mortars allows vernacular buildings to “breath”, which helps to regulate moisture levels and prevent dampness. In addition, traditional lime mortars are more sympathetic to traditional stonework, allowing traditional buildings to retain their original appearance.
These efforts are essential for preserving Yorkshire’s heritage buildings vernacular buildings are structures built using a particular region’s local materials.
The term vernacular can also be used to describe architectural style. In Yorkshire, vernacular architecture is characterised by the use of stone and brick and timber framing. Lime mortars are among the most distinctive features of vernacular architecture in Yorkshire.
Hot lime mortars are made from quick lime, water, and sand. They were used extensively in the construction of vernacular buildings in Yorkshire. The lime mortar joints allowed for flexibility, which helped to prevent cracks from appearing within the mortar as the building settled. In addition, lime mortars allowed for the easy repair of vernacular buildings.
Lime is a traditional material that has been used for centuries, and by using it, we can help to preserve the past. By using traditional materials, we can help to keep our heritage alive.
Lime Pointing
Any home or building owner knows that repair and maintenance costs can quickly add up. But the stakes are even higher for those who own historic buildings. That’s because these buildings are not only a valuable part of our heritage but also require special care to maintain their structural integrity.
One of the most critical aspects of traditional building repair is traditional materials. Hot lime mortar, for instance, has been used for centuries in vernacular construction and is known for its durability and long-lasting strength. That’s why it’s essential to use a qualified heritage builder with experience working with lime mortar. Ignoring this fact can cause more damage to the building, meaning more costly repairs. So if you’re responsible for a historic vernacular building, ensure you’re doing everything possible to protect this valuable piece of our heritage.
The Yorkshire Lime Company specialises in lime pointing, a process of repairing and restoring traditionally built structures. Our team is trained in the preparation and use of historic mortars, meaning we can match the colour and consistency of the original mortar. We also have the expertise to match the historic finish of the mortar, ensuring that your property looks the way it would have all those years ago. Whether you are looking to repair damage from weathering or simply want to restore your property to its original glory, we are here to help.
Yorkshire’s historic buildings and brick work have stood the test of time, thanks in large part to the enduring strength of traditional lime mortars. These time-honoured materials have been integral to the construction and preservation of our region’s historic buildings. The art of traditional lime pointing, which involves restoring mortar joints with traditional lime mortar, plays a pivotal role in maintaining the structural integrity and aesthetic authenticity of these architectural gems.
Our recent lime pointing project on a historic gable wall serves as a testament to the unparalleled craftsmanship and dedication of The Yorkshire Lime Company. The gable wall, bearing the scars of time and wear, required expert attention to bring it back to life. Our team carefully assessed the condition of the existing mortar and masonry walls, recognising the need for traditional lime mortars to rejuvenate the structure.
Heritage buildings often suffer from the ravages of time, with existing mortar joints crumbling and deteriorating. It’s in these moments that the importance of traditional lime pointing becomes most apparent. Traditional lime mortars, being both flexible and breathable, prove to be the perfect solution for restoring the integrity of masonry walls and safeguarding the historical value of our cherished historic buildings.
Traditional lime mortars are not only practical but also aesthetically pleasing. During our lime pointing projects, we meticulously match the colour, texture, and composition of the original mortar, ensuring that the transformation is seamless. The result is a gable wall or any historic structure that looks as if it were frozen in time, maintaining the charm and character of a bygone era.
The use of traditional lime mortars in our preservation work is a testament to our commitment to guarding Yorkshire’s architectural legacy. By embracing the principles of traditional craftsmanship and using lime-pointing techniques, we stand as custodians of our region’s history. Our aim is not only to preserve historic buildings but to pass them on, undiminished, to future generations, ensuring that the stories they hold continue to inspire and captivate.

Earth Mortar Pointing & Repairs
Earth mortars are a vital part of building conservation. They are made from local natural subsoil, where clay minerals bind to sand and silt particles. Topsoils, which contain organic matter, are unstable and are never used. Long-term weathering research published by Historic Environment Scotland in 2015 found that the critical factor in the performance of a mortar is particle size distribution. If an earth mortar is well graded (that is to say, containing a good range of particle sizes, not just fine particles), it will have good working qualities and prove resilient. If poorly graded, it will always be vulnerable to progressive decay. Earth mortars are environmentally sound mortars, as they require no energy to produce and can be sourced from local materials. When properly made and applied, earth mortars can provide long-lasting and durable repair.
Pointing is renewing the external surface of mortar joints in masonry construction. It involves the removal of old, damaged or decayed mortar from joints. This is followed by the repair or replacement of mortar with new material. The use of hot-mixed air lime mortars for pointing is becoming increasingly popular due mainly to their compatibility with earth mortars. Hot-mixed air lime mortars offer several benefits over traditional Portland cement-based mortars. Including improved breathability, compressive and flexural strengths, and workability.
Earth mortars have been used in building construction for millennia, and their use can be seen in a wide variety of structures across the UK and Ireland. In recent years, there has been an increasing awareness of the potential problems incompatible mortars can cause. As a result, many building owners are now taking steps to ensure that their properties are repaired with compatible materials. This is particularly important for earth-built structures, which are particularly vulnerable to the damaging effects of hard-setting mortars. NHL mortars, in particular, have been shown to cause severe problems for earth buildings. As such, they must only be used on compatible materials. We can ensure that earth buildings remain standing for generations by repairing them with suitable materials.
Earth mortars have been used in construction for thousands of years and remain an important part of masonry today. Earth mortars are made from a mixture of clay, sand, and water, and they are ideal for bonding bricks and stones. However, earth mortars are also susceptible to weathering and thermal expansion damage. As a result, it is important to use the correct conservation methods when repairing earthen mortar structures. The Yorkshire Lime Company has extensive experience in traditional masonry repairs, and our trained professionals can restore your earthen mortar structure to its original condition.
Hot Mixed Lime Mortars For Pointing
Hot-mixed lime mortar is one of the oldest types, dating back to the early days of masonry construction. Its basic form is simply a mixture of quicklime, water and an aggregate such as sand. Quicklime is a highly reactive form of calcium oxide produced by heating limestone in a kiln. When mixed with water, it undergoes a chemical reaction known as ‘slaking’, which generates heat. This ‘slaked lime’ can then be combined with the aggregate to produce hot-mixed lime mortar. The use of hot-mixed lime mortar has several advantages over other types of mortar. It initially sets very quickly, allowing masons to lay bricks or stones faster than different mixes. It also produces a strong bond between the bricks or stones, making for a more durable structure.
Hot mixed lime mortar can be used for building, plastering and pointing work. It produces the most benefits when it is used while it is still warm; this is because it evaporates any unwanted moisture enabling it to stiffen up faster. Because the lime stiffens, it is less prone to lime leaching during rain storms, and this also makes it less susceptible to frost damage due to it evaporating the excess moisture from within it. Because of this, you can build and point through winter months as long as protection from the elements has been put in place. Unlike modern Hydraulic lime mortars, hot lime mortar relies on air movement to carbonate, meaning it does not need regular hydration as modern natural hydraulic limes require.
At the Yorkshire Lime Company, we pride ourselves on our ability to mix, apply, and care for any lime binder.

Lime Mortar Mix for Pointing
Quicklime (calcium oxide) is produced by heating limestone (calcium carbonate). This process drives off carbon dioxide gas, leaving behind quicklime. Quicklime can be very unstable and will combine energetically with water to produce lime (calcium hydroxide) and release heat. If quicklime is mixed with water to create a mortar, the resulting mixture can reach high temperatures very quickly. By controlling the quicklime-water reaction, it is possible to create a strong and durable mortar.
The hot mixing process involves mixing calcium oxide (quicklime) with water to create calcium hydroxide, also known as slaked lime. This slaked lime is mixed with grit sand and other ingredients like coal grit and fuel ash, which act as bulkers and pozzolans. The resulting mixture is typically used in historic preservation. It is much more environmentally friendly than traditional cement mortars. In addition, hot lime mortar is much more resistant to freezing and thawing cycles. This makes it an ideal choice for exterior applications. As a result, using hot lime mortar for pointing can help reduce the environmental impact of construction projects while still ensuring a high level of Breathability and durability.
All Aspects of Lime Mortar Pointing in Yorkshire
In the past, lime was the most commonly used material for construction and decoration. Today, hot lime pointing is an essential part of conservation efforts for vernacular buildings. Not only is it environmentally friendly, but it also helps to improve the functionality of the building. Lime mortar is an active capillary material which can absorb and release moisture.
This helps to regulate indoor humidity levels, preventing condensation build-up, which can lead to dampness and mould growth. In addition, lime is a breathable material, which allows vapour to pass through it. This helps to prevent trapped moisture from causing structural damage to the building. Finally, lime is flexible and can expand and contract without cracking. This makes it ideal for use in facilities where temperature and moisture levels fluctuate, preventing cracks from forming, which could lead to water ingress. Overall, lime pointing is an essential part of vernacular building conservation efforts as it helps to improve the functionality of the building while also being environmentally friendly.

Frequently Asked Question On Heritage Bricklaying
Pointing is the process of filling the joints between masonry units (e.g. bricks, stones) with mortar. The primary purpose of pointing is to improve the weather resistance of the masonry wall by preventing water ingress. However, pointing can also be used for aesthetic purposes. The first signs your building will need pointing are missing and eroded mortar between the masonry joints. Another sign is any cracking along the mortar joints; this cracking can be caused by thermal expansion and the use of inappropriate materials. Finally, if you are suffering from dampness inside the home, cement mortar pointing is one of the leading causes of dampness in traditionally built homes. Cement mortar traps moisture behind it, causing the masonry to erode, and damp patches will appear internally. Lime mortar is the mortar that should be used on traditionally built homes. Lime mortar is more porous than cement mortar, allowing moisture to pass through it while providing an effective barrier against water ingress.
Patch pointing is a process of repairing worn or damaged mortar joints in masonry construction. The patching material used to repair the joint must match the materials and finish of the existing mortar joint to blend in and not alter the appearance of the building. To do this, various grains of sand may be sourced to achieve the desired colour, and different binders can be used to match the consistency of the existing mortar. Once a patching material that closely resembles the existing mortar joint has been identified, it can be applied and finished in the same style. This will ensure that the patch is undetectable and does not affect the aesthetic appeal of the building.
If you live in a traditionally built home, it has likely been built with hot lime or earth mortars, depending on the age and location of the building. When undertaking pointing repairs on these buildings, it is essential to match the existing fabric so the functionality of the building is not compromised. When making repair mortars for pointing, it is vital to match the porosity of the existing mortar so that the capillary rate stays the same between old and new. Using matching grits in colour and particle size combined with the correct lime binder will prevent a barrier from being created between the two mortars. There are many different binders, and not all are suitable for repairing traditional homes. In order to select the most appropriate binder, it is important to consider the required service life and the compressive strength and shrinkage characteristics of the mortar. For example, hot lime mortar (when used hot) has a low shrinkage rate, and it is also suitable for historic buildings where long-term durability is critical. In contrast, hydraulic limes are more commonly used in modern construction due to their higher strength and lower shrinkage. As a result, it is essential to select the right binder when undertaking repair work on traditional buildings.
The type of lime you use for pointing would depend on the type of masonry you will be applying the pointing to. For example, you would use pure lime putty on ashlar masonry or decorative Georgian brickwork, whereas` quicklime mixed with aggregates and slaked with water was used to create a hot mixed mortar for the construction of many other traditional homes. The location of the building also has to be taken into account buildings in highly exposed areas require a more durable mortar, and pozzolans like coal ash, trass and brick dust are added to quicklime to create a hydraulic mortar which enables it to withstand the elements. At the Yorkshire Lime Company, we specialise in the use of historic mortars and can advise and guide you on the correct binders needed for the location you are based in. Whether you’re looking to repoint an entire building or repair some existing damage, we have the expertise and materials necessary to help you achieve a professional finish. Contact us today to discuss your requirements.

Hot lime mortar is a lot more durable against weather conditions. It only holds the moisture it needs to set and removes any unwanted moisture. Applying the mortar hot means the heat evaporates excess water preventing frost damage. It is advised to keep the wall dry during winter by providing cover from the elements. Hessian can cover the wall and protect it from frost, and scaffolding with breathable sheeting can be erected to protect the walls from driving rain. At The Yorkshire Lime Company, we undertake hot lime pointing work all year round.
