Repointing is a process that involves repairing the mortar joints between the bricks, stones, and other masonry materials used to construct a building. Repointing is also known as pointing, tuckpointing, or brickwork.
Over time, the mortar joints in a building can deteriorate due to weathering, age, or improper maintenance, which can lead to cracks, holes, and gaps in the mortar. Repointing is an essential part of maintaining the structural integrity of a building, and it can help prevent further damage and decay.
Why Is Repointing Important?
Repointing roof tiles and other parts of the home is crucial for several reasons. Firstly, it helps to maintain the structural integrity of a building.
When the mortar joints between the bricks or stones start to deteriorate, the structural stability of the structure can become compromised by repairing and replacing the broken mortar, repointing aids in restoring the building’s strength and stability.
Repointing also aids in avoiding water damage. Water can seep into a structure through deteriorated mortar joints, damaging the interior and exterior walls. Mould development, rot, and decay caused by water damage can be challenging and expensive. This is because filling the mortar’s gaps and fractures and repointing aids in preventing water from entering the building.
Finally, repointing can help to enhance the aesthetic appeal of a building. Over time, the mortar joints can become discoloured, stained, or damaged, which can detract from the appearance of the building.
Repointing can help to restore the original beauty of the building by replacing the damaged mortar with new, fresh mortar that matches the colour and texture of the existing mortar.
How Is Repointing Done?
Repointing is a complex process that requires skill, knowledge, and experience. The first step in repointing is to assess the condition of the existing mortar joints. The masonry contractor will look for degradation indicators like cracks, gaps, holes, or cracks in the mortar joints.
Based on the assessment, the contractor will determine the extent of the repairs needed and develop a plan for repointing.
The next step is to remove the damaged mortar. The contractor will use a chisel, hammer, or grinder to remove the old mortar between the bricks or stones.
The goal is to remove the damaged mortar without damaging the bricks or stones. This procedure can be labour- and time-intensive, necessitating a deft touch to protect the stonework.
Once the damaged mortar has been removed, the contractor will clean the joints. The contractor will use a wire brush, compressed air, or water to clean the joints, removing any loose debris or dust. This step is essential because it helps ensure the new mortar will adhere adequately to the bricks or stones.
The next step is to prepare the new mortar. The contractor will mix the new mortar using a combination of sand, lime, and cement. The mortar must be combined to the correct consistency, which can vary depending on the type of masonry and the climate conditions.
The cannon should be stiff enough to hold its shape but not too stiff that it cannot be easily applied to the joints.
The final step is to apply the new mortar to the joints. The contractor will use a trowel or pointing tool to spread the cannon to the joints, filling in the gaps and smoothing the surface. The objective is to produce a uniform, smooth surface that fits the mortar’s colour and texture.
Maintaining a building’s structural integrity and aesthetic appeal requires regular repointing. It is a complex process that requires skill, knowledge, and experience. Suppose you notice signs of deterioration in the mortar joints of your structure.
