Brick buildings are a testament to durability and timeless beauty in commercial architecture. However, even the sturdiest structures require maintenance to withstand the test of time. One crucial aspect of brick building upkeep is repointing – a process that can significantly extend the life of your commercial property. In this comprehensive guide, we’ll explore the ins and outs of brick repointing, helping you understand when it’s necessary, why it’s important, and how it’s done.

Signs That Your Commercial Building Needs Repointing

Recognizing the need for repointing early can save you from costly repairs down the line. Here are some telltale signs that your commercial building’s brickwork may need attention:

• Crumbling or missing mortar: If you notice mortar falling out or visible gaps between bricks, it’s time to consider repointing.
• Cracks in the mortar joints: Small cracks can quickly become big problems, allowing water to penetrate and cause further damage.
• Efflorescence: White, powdery deposits on the brick surface indicate that water is moving through the masonry, potentially due to deteriorating mortar.
• Damp interior walls: If the inside of your building shows signs of moisture, failing mortar joints could be the culprit.
• Loose bricks: When mortar fails, bricks can become unstable, posing safety risks and compromising the structure’s integrity.

Regular inspections of your building’s exterior can help you catch these issues early. It’s recommended to have a professional masonry inspection at least once a year, or more frequently for older buildings.

The Repointing Process Explained Step-by-Step

Brick repointing is a meticulous process that requires skill and attention to detail. Here’s a breakdown of the steps involved:

1. Inspection and Assessment: A thorough examination of the brickwork to determine the extent of the damage and the appropriate course of action.
2. Mortar Joint Preparation: The damaged mortar is carefully removed to a depth of at least 3/4 inch or until sound mortar is reached. This is typically done using specialized tools to avoid damaging the surrounding bricks.
3. Cleaning: The joints are cleaned of debris and dust, usually with water or compressed air, to ensure proper adhesion of the new mortar.
4. Mortar Mixing: New mortar is prepared, matching the composition and color of the original as closely as possible (more on this in the next section).
5. Mortar Application: The new mortar is carefully applied to the prepared joints using a pointing trowel or mortar gun. It’s important to fill the joints completely without smearing mortar on the face of the bricks.
6. Tooling: Once the mortar has set slightly, it’s shaped to match the original joint profile using specialized tools. This step is crucial for both aesthetics and functionality.
7. Curing: The new mortar is allowed to cure properly, which may involve covering the work area to protect it from direct sunlight and wind, and misting with water to prevent rapid drying.
8. Clean-up: Any residual mortar on the brick faces is carefully cleaned off to restore the building’s appearance.

This process requires skill and experience to execute properly, which is why it’s generally recommended to hire professional masonry services for commercial repointing projects.

Choosing the Right Mortar for Repointing

Selecting the appropriate mortar is crucial for successful repointing. The new mortar should be compatible with the existing brickwork in terms of strength, composition, and appearance. Here are key factors to consider:
