Lime mortar first came around in the ancient Egyptian period and was also used a lot when building the Roman Empire. It’s considered to be a traditional building material and has predominantly been used up until the 20th century, with this in mind, it’s important to remember that it is not a cement mortar.
Traditional lime mortar does not include cement it is also not made with hydraulic lime, hydraulic lime sets by reacting with water whereas quick lime is more renowned for the traditional elements it possesses as well as avoiding using any modern ingredients, it was concrete and cement that took over the popularity of lime mortar.

We had a problem with deterioration of a sandstone wall due the joints being pointed over with cement mortar stopping the drying of the stone. We were advised by a specialist that the mortar needed to be taken out and repointed with a lime mortar and advised that it needed to be done by hand not mechanically and we should look for a mason experienced in such work. Thankfully we found Gillards. Lee and his team were very knowledgeable and knew exactly what the problem was and have done a fantastic job. I would highly recommend Gillards Building & Maintenance Services and will use their services again if the need arises.
Wakefield Lime Mortar Pointing
The look and appearance of the brick and stone masonry will involve the mortar joints as much as the stone and bricks themselves. The wrong type of repointing can affect the durability and the look of the masonry. It tends to be the most common cause of damage to the fabric and character of historic buildings and properties. Repointing of a building is needed when it comes to buildings exposed to the weather or if they are affected by specific problems like leaking pipes or gutters. Sound historic mortar should be left as it can be an essential part of the significance and character of a building.
Modern cement render isn’t compatible with the construction of older buildings and it can cause and lead to decay. Modern building’s structures use outer layers and cavities that will help to keep moisture out, older buildings will rely on permeability and breathability which allows water to be absorbed and then evaporated. Using a cement render instead of traditional lime mortar pointing can restrict this evaporation process. Hairline cracks may form, this is due to the mortar being a lot more rigid than the wall, they will then draw in water which will become trapped in the material. Timber and earth constructed buildings may also suffer from structural damage if the moisture builds up behind the cement.
Pointing is the process of filling outer parts of joints, joints that are between masonry units, it can be done as a part of other work, or it can be carried out by striking off the bedding mortar flush with the face of the masonry or separately if the outer part of the bedding mortar has been left or has been taken back from the surface. When it comes to brickwork and stonework the profile, texture and width will affect the visual character and in these cases locally available materials may need to be used as they will support the building visually. Over the years bricklayers have tried to ensure that their projects look as regular as possible, from the Elizabethan and Tudor periods, there was a trend towards narrow joints, this is because bricks of consistent sizes were more readily available. Joint width also tended to be associated with status, for example, the quality of the brickwork, the narrower the joints, culminating in gauged work when joints could be less than millimetre wide.
For Choosing The Right Binders and Aggregates
Lime binders are available in different types and are suitable for many applications and locations, the two main types of lime binders are non-hydraulic lime and Hydraulic lime mortars, they are mostly known as being made from lime putty, burnt lime stone or hydrated powders quick lime and nhl Both are available in a hydrated powder form this is why it is referred to as ‘builders lime’, it is used as a plasticiser in a cement mortar or more suited for applications where a natural air lime won’t set usually in very damp or wet conditions it isn’t suited for making traditional lime mortars.
Hydraulic lime has been found to have similar properties to cement after stated setting times. NHL lime hardens by reacting with moisture and needs wetting down periodically after applications this is needed to create the hydraulic reaction.
Quick lime sets by reacting with co2 as air circulates the building the lime reacts pulling the moisture content out this reaction is also part of the curing process. If supplied as lime putty, the lime will be protected from the air because it’s saturated with water and then can be covered with a film or water from the moment that it’s made. In its dry form, the lime will be supplied in bags or sacks as dry powder or small granular lumps of quick lime it is important to store the lime in the correct conditions or premature carbonation will be inevitable and its performance will be less predictable.
- If the original lime pointing has decayed over time and needs replacing, this may just be gradual decay from weathering or poor maintenance.
- The masonry has been repointed with cement mortar and its causing problems to the building, this will need replacing.
