Due to changing weather conditions, wetting and freezing cycles, mortar joints can be eroded over a period of years. It majorly occurs in older buildings wherein the bricks and mortars are softer.
The mortar joints can be renewed or replaced by Brick repointing, which is the process of removing the damaged mortar and replacing it with the new mortar. This process isn't an easy job and it requires a professional with a high degree of knowledge, experience and skill about matching the new mortar with the original one.
Proper Time to Repoint
The need of repointing arises when existing mortar joints are either eroded when the mortar has shrunk away from the most of the edges of the brick. The major goal of brick repointing is to restore the brick to its original appearance.
Let us have a look at the and the repointing process of the blockwork:
Examine the structure:-
Before starting any work, it is important that building owners examine the techniques used in the construction and the type of original mortar used. This helps in identifying the true problem with the construction and find out the causes of cracks and deterioration.
Construction Process:-
1) Removing the old mortar: After you've examined the blockwork and the building, the next step is to cut away the old mortar. It should be done carefully so as to avoid any damage to any masonry units. After the cutting out of the old mortar the joints are cleaned by a brush and space is vacuumed. The remaining mortar is removed by a water jet.
2) Filling in the new mortar: The areas which have the deepest recession are filled first. Several layers of mortars are placed inside the recession and it is continued until the mortar is flushed with the masonry. The mortar needs to stay wet for a couple of days before setting.
