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.

When replacing lime mortar it’s crucial to ensure the new joints have been raked out properly. This is to allow the new mortar enough space to bond and set.
Once cleared, the open joints should then be soaked with water.
Again this gives the new mortar the best conditions to set.
Once the lime mortar has been applied, we would then cover the stonework with a material called hessian. This natural material creates the ideal environment for curing while also protecting the new mortar from adverse weather conditions.
When partially set, the new mortar is ready to be brushed back. This will reveal the aggregate within the mortar and create a watertight and breathable structure.
