Traditional Lime Mortar pointing

Lime mortar is a traditional type of mortar that is made using lime and sand. It is more flexible and breathable than cement-based mortars. When used in stonework, it can help to preserve the integrity and longevity of the stones, as well as providing a more sustainable and environmentally friendly option.

Pointing in your stonework is something that’s sometimes overlooked by homeowners, but it shouldn’t be. A small area of missing/failed mortar may not be deemed serious at first but can definitely contribute to pretty serious unwanted problems in the future if left unmaintained.

Water ingress is one of the most common causes of failed masonry, therefore should be maintained at all times. Lime Mortar is a porous material which allows the masonry to breathe and release moisture from within which will avoid internal damp issues. Even after the fully cured stage it is softer than most of the surrounding masonry, providing a bit of flex in the building allowing for natural movement and will help prevent cracking/fractures.

Modern cements are quite the opposite and should not be used with natural stone. Cement is non porous and tends to trap moisture behind if water finds a point of entry. This is why you often find your sandstone crumbling where cement is present on the building. This can be avoided by using the right materials and making sure you have the right tradespeople for the job.
