Stone buildings, chimneys, and walls all require maintenance to ensure they last as long as possible. In most scenarios, maintenance is carried out on the joints between masonry, as they can become weathered and eroded over time. When this happens, it makes your stone structures look a lot worse, but can also cause them to less weatherproof than they used to be.
The best way to address this is with a repair/maintenance task known as pointing. Traditionally, builders and masons used cement mortars to fill in any holes between the brickwork and maintain the structural integrity of a stone building. However, we use lime pointing instead, as it’s a much better option in our eyes.
What is Lime Pointing?
Lime pointing differs from traditional pointing in that lime mortar is used instead of cement. However, the actual pointing process is pretty much the same. We mix our lime putty based mortar together and use it to fill any gaps between the stones in your home, chimney, or exterior walls. We can do this when building these structures for you, or as a maintenance/repair task in the form of repointing. The lime mortar is inserted into the cavities and left to set and seal up any gaps.
Why is Lime Pointing the best option?
We exclusively use lime mortar whenever we carry out any pointing jobs. This is because it’s merely the best option out there, and is far more beneficial than typical cement pointing.
One of the main reasons we see it as the only option is because lime mortar tends to be much softer than cement. Immediately, this makes it easier for us to work with, as the mortar moulds itself into each cavity with such ease. However, this softness also means that the lime mortar is more porous than cement. What this means is that it has loads of tiny little holes in it. Why is this a good thing? Because it helps control moisture levels in your stone structures. Thanks to the holes, any moisture can easily evaporate through them, ensuring none stays behind and lingers, leading to possible problems with damp in the future.
The other benefit of lime pointing is that it’s far healthier for your stone structures. The problem with cement pointing is that you fill the gaps with a substance that’s essentially just as hard as the stones around it. As time goes by, masonry tends to move slightly and shift about. When cement is present between the joints, it makes it hard for this to happen without cracks appearing, due to the hardness of it. With lime pointing, you have this far softer material that lets your home move freely without worrying about cracks or erosion.
If you’re ever in need of pointing or repointing work, then lime pointing is the best idea around. It’s highly recommended you seek out a professional stonemason to handle this task. Regular builders or handymen don’t have the skills or knowledge to understand how to mix lime mortar properly and apply it correctly. If you’re looking for a stonemason, then feel free to give us a call, and we’ll help with this task.
