After assessing the extent and severity of the cracks in the chimney bricks, the next step in restoring the damaged masonry involves replacing the deteriorated mortar joints. Mortar joint deterioration is a common issue in chimney masonry and can lead to structural instability if left unaddressed. To rectify this problem, repointing techniques are employed to remove the old, damaged mortar and replace it with fresh mortar.

The first step in replacing damaged mortar joints is to carefully remove the existing mortar. This is typically done using a chisel and hammer, ensuring that the surrounding bricks aren't damaged in the process. Once the old mortar has been cleared, the joints are cleaned thoroughly to remove any loose debris or dust.

Next, a new mortar mixture is prepared, taking into account the specific requirements of the chimney. A high-quality mortar mix is recommended, which typically consists of a combination of cement, lime, and sand. The mixture should be properly proportioned to achieve the desired strength and durability.

The new mortar is then applied to the joints using a pointing trowel. It's important to ensure that the mortar is compacted well and fills the joints completely. Excess mortar should be cleaned off the brick surfaces using a brush or sponge.

Lastly, the newly repointed joints should be left to cure for a few days. This allows the mortar to harden and gain strength, providing a solid and stable structure.

Waterproofing the Chimney Masonry
