Should I Waterproof My Exterior Brick?

Brick is a popular choice for exterior design due to its longevity, durability, and look. It has been used for centuries due to its low maintenance, meaning touch-ups are not required. However, your brick could age with small cracks from moisture and freezing temperatures. We recommend applying a waterproof treatment to your exterior brick to prevent this. Here is everything you need to know.

What Is Waterproofing?

Waterproofing your exterior brick involves applying a protective sealant to the brick surfaces. This can help fill in cracks while keeping the brick in its best condition. You can choose from a variety of options, including liquid sealants, breathable coatings, or water repellents. Once the treatment is applied, all you have to do is wait for it to dry, and your brick exterior will be more protected than ever.

Reasons You Should Waterproof Your Exterior Brick

Seals Against Moisture

Moisture can impose threats to your exterior brick, such as causing small cracks. If the cracks appear, it can cause leaking. Leaking can cause problems, from mold growth to intense smells and flooding, if the leak gets bad enough. Waterproofing your exterior can prevent leaks from happening, as it seals the brick against moisture, filling any cracks that may have occurred over time. 

Preserves Natural Look

One reason brick is popular is its rustic yet charming appearance. Applying a waterproof treatment to your exterior brick can also help preserve its natural look. The treatment will protect it from damage from the weather while keeping it just as beautiful as when you first saw it. 

Prevent Freeze-Thaw Damage 

During winter, freeze-thaw damage can occur. This is when water seeps into the brick’s pores and then freezes. When the water freezes, it expands, causing pressure on the structure. The brick expands, causing cracks and pieces to break off. This is more common in places with a lot of snow and rain during winter. Applying a protective coat to your brick can keep your exterior safe during the cold season.

Keeps It Clean

Once the coating is applied, it will help keep your brick exterior clean. When dirt enters small spaces in the brick, humidity can collect, making it a threat.  When applied, the coating blocks those tiny areas where the moisture can enter. This means less dirt buildup, which can eventually cause mildew or moss.
