How to Repair Damage Caused by Snow Removal Salt on Masonry Walls?

The beauty of masonry can be timeless, but unfortunately, the harsh Quebec winter can leave scars on your masonry walls. Snow removal salt, while a valuable ally for our icy roads, can prove to be a formidable foe to the masonry of your home or building. In this article, we will explore the ravages of snow removal salt on masonry walls and provide you with a comprehensive guide on how to repair the damage caused by this corrosive substance. If you reside in Montreal, Laval, Longueuil, the South Shore, or the North Shore, this guide is specially crafted to assist you in preserving and restoring the beauty of your masonry walls.

The Invisible Ravages of Snow Removal Salt

Snow removal salt, also known as sodium chloride, is widely used to clear roads in winter. However, its excessive use can have serious consequences for your masonry walls. Here's how it can damage your masonry in ways that may not be immediately visible:

1. Surface Erosion

Snow removal salt is a corrosive substance that can erode the surface of bricks, stones, and concrete. It can gradually degrade the texture and color of your masonry, leaving behind a dull and rough surface.

2. Water Infiltration

One of the most insidious effects of snow removal salt is its ability to attract moisture. When salt comes into contact with masonry, it absorbs moisture from the air, creating an environment conducive to cracks and water infiltration.

3. Joint Deterioration

Snow removal salt can lead to the deterioration of masonry joints. Joints are essential for maintaining the structural integrity of your masonry, and their weakening can make your walls vulnerable to damage.

Step-by-Step: Repairing Damage Caused by Snow Removal Salt

Now that we understand the invisible ravages of snow removal salt, let's see how you can repair these damages and restore the beauty of your masonry walls. Here is a step-by-step guide:

Step 1: Damage Assessment

Before embarking on any repairs, it is crucial to assess the extent of the damage. Carefully examine your masonry walls to identify cracks, surface erosion, and damaged joints.

Step 2: Thorough Cleaning

Begin by thoroughly cleaning the masonry to remove any residue of snow removal salt. Use a high-pressure washer to eliminate dirt, salt deposits, and efflorescence.

Step 3: Crack Repair

To repair cracks, you can use a masonry repair mortar specifically designed for the task. Carefully fill the cracks, ensuring that the mortar is smooth and uniform.

Step 4: Surface Restoration

If the surface of your masonry has been eroded, consider applying a repair coating. This will help restore the original texture and color of the masonry.

Step 5: Joint Refurbishment

If the joints are damaged, carefully remove and replace them with suitable mortar. Ensure that the joints are compact and uniform.

Step 6: Application of Sealant

To prevent future damage from snow removal salt, apply a masonry sealant. The sealant forms a protective barrier against moisture and salt.

Step 7: Regular Maintenance

The key to keeping your masonry walls in perfect condition is regular maintenance. Make sure to clean any snow removal salt buildup after each winter and monitor for signs of damage.
