If you have a brick chimney, it’s important to periodically check the condition of the mortar and repair it as needed. Repointing a chimney is a process of removing the old, damaged mortar and replacing it with new mortar. This helps to seal the gaps and prevent further damage. There are many different types of pointing materials available, so it is essential to choose one that is compatible with the current mortar. Once the correct material has been selected, the repair work can begin.
Firstly, any loose or damaged mortar must be removed from the chimney, before the new pointing can be started. Once the area has been prepped, new pointing can be applied using the appropriate pointing tools. It is essential to make sure that no gaps are left between the bricks, and the area is left undisturbed for at least 12 hours to ensure the pointing stiffens up. Lastly, the lime mortar is beaten with a churn brush to compact it tightly into the joint and then dressed to the desired finish.
