Pointing (Masonry)

In the field of masonry, pointing refers to the process of filling the gaps between bricks or stones with mortar. This technique is commonly used in the construction or restoration of brick or stone walls to provide structural stability and a more polished appearance.

The process of pointing begins with the removal of any old, damaged or deteriorated mortar from between the bricks or stones. This is typically done using specialized hand tools or power tools such as chisels, grinders or drills. The area is then cleaned to ensure that it is free from debris and dust before the pointing process can begin.

The next step is the preparation of the new mortar mixture. This typically involves a mixture of cement, sand, and water, but can vary depending on the specific application. The mortar must be mixed to the proper consistency to ensure that it can flow into the gaps and adhere to the surrounding bricks or stones.

Once the mortar is prepared, it is applied to the gaps using a specialized pointing trowel. The mortar is forced into the gaps and smoothed to ensure a consistent and even appearance. It's important to note that the mortar used in pointing must match the existing mortar in color, texture, and consistency to ensure a seamless finish.

There are a few different styles of pointing commonly used in masonry. The most common styles include flush pointing, weathered pointing, and recessed pointing. Flush pointing involves applying the mortar until it is flush with the surface of the bricks or stones, while weathered pointing creates a slope leading away from the joint to help shed water. Recessed pointing is a popular option for historic buildings, where the mortar is set back slightly from the surface of the bricks or stones to create a shadow effect.

Overall, pointing is an essential aspect of masonry and has an important role in ensuring the structural integrity and aesthetic appeal of brick and stone structures. A well-executed pointing job not only provides a watertight seal but also adds value and longevity to any masonry construction project.
