What is pointing?

Pointing, also known as repointing, is the process of renewing the external mortar joints between bricks, stones, or other masonry units in a building. Over time, mortar joints can deteriorate due to weathering, settlement, or other factors, which can lead to water infiltration and damage to the masonry structure.

The pointing process involves removing the damaged or deteriorated mortar and replacing it with new mortar that matches the color, composition, and texture of the original mortar. The new mortar is applied to the cleaned and dampened joint using specialized tools and techniques and then tooled to provide a smooth and uniform finish.

Pointing is an important maintenance task for masonry buildings because it helps to prevent water infiltration, improve the structural integrity of the building, and enhance its aesthetic appeal. It is typically performed by skilled masons or contractors who have experience in working with different types of masonry materials and mortar mixes.
