How does repointing service work? Masonry Montreal

Demystifying the repointing process by Maçonnerie Montréal

The basics of repointing

Repointing is a crucial masonry maintenance process that involves removing damaged or deteriorated mortar from between bricks or stones and replacing it with fresh, new mortar. This not only enhances the appearance of the masonry structure but also strengthens its integrity and extends its lifespan. In this article, we will delve into how the repointing service works and how Maçonnerie Montréal ensures the highest quality results.

Step-by-step breakdown of the repointing process

Repointing may seem like a straightforward task, but it requires specialized skills and knowledge to ensure proper execution. The following is a detailed breakdown of the repointing process:

Step 1: Inspection and assessment

The first step in the repointing process is a thorough inspection and assessment of the masonry structure. This helps to identify any areas where mortar is damaged, loose, or missing and determine the extent of the required repointing work. It is also essential to evaluate the type of mortar used to ensure that the new mortar matches the original in terms of strength, composition, and color.

Step 2: Mortar removal

Once the damaged areas have been identified, the next step is to carefully remove the old mortar from the joints. This is usually done using specialized tools, such as a grinder or chisel, to ensure that the surrounding bricks or stones are not damaged during the process. The depth of the mortar removal should be approximately twice the width of the joint to ensure a proper bond with the new mortar.

Step 3: Cleaning the joints

After the damaged mortar has been removed, the joints must be thoroughly cleaned to remove any dust, debris, or loose mortar that may hinder the adhesion of the new mortar. This can be done using a wire brush, compressed air, or water, depending on the specific requirements of the project.

Step 4: Mixing and preparing the new mortar

The new mortar must be carefully mixed to match the original mortar's composition, strength, and color. This may involve using a pre-blended mortar mix or creating a custom mix using the appropriate sand, cement, and lime. Once the mortar has been mixed to the correct consistency, it should be allowed to sit for a short period to ensure proper hydration before application.

Step 5: Applying the new mortar

The new mortar is applied to the joints using a specialized tool called a trowel. The mortar should be packed firmly and evenly into the joints, ensuring that no air pockets or voids are present. The joints are then finished using a jointer tool, which shapes and compresses the mortar to create a smooth, watertight seal.

Step 6: Curing and cleaning

After the new mortar has been applied, it must be allowed to cure for a specified period, usually between 24 and 72 hours, depending on the mortar type and environmental conditions. During this time, the mortar should be kept damp to prevent premature drying and cracking. Finally, any excess mortar is cleaned from the surface of the bricks or stones, and the work area is tidied up, leaving your masonry structure looking revitalized and well-maintained.
