6 Ways to Care for Exposed Brick Walls to Prevent Them from Getting Moldy and Dull Too Quickly

Exposed brick walls certainly have their own unique charm. Their natural texture and color can make a building look warmer and more natural, while also giving it a strong character. However, there’s one thing that’s often overlooked: maintenance.

Many people think that exposed brick doesn’t need any maintenance—you can simply leave it alone and its character will remain visible for years to come. 

In fact, this is a big mistake—exposed stone that isn’t maintained will quickly become dull, covered in dust, and even overgrown with moss. This is especially true if the wall is located outdoors, where it’s constantly exposed to rain and sunlight.

Therefore, Milanians need to know the proper way to care for exposed brick walls so that they remain attractive and the material is better protected. Maintenance is actually not difficult, as long as it’s done regularly and with the right protective measures. 

Why Exposed Brick Building Walls Require Special Care

Exposed brick has a surface that tends to be porous. This makes the material more prone to absorbing water and moisture than a wall surface that has been coated with a waterproof finish.

When water seeps into the pores of the bricks and doesn’t dry quickly, this environment can become an ideal place for moss and mold to grow. Over time, excess moisture can also cause the bricks to change color and make their surfaces look increasingly dull.

In addition to water, dust, dirt, and exposure to sunlight can also affect the appearance of bricks. That’s why caring for exposed brick walls isn’t just about keeping them clean, but also about protecting their surfaces from environmental factors.

The Main Reasons Why Exposed Brick Walls Quickly Become Mossy and Dull

1. Constant Exposure to Rain and Sunlight

Exposed outdoor brick walls are directly exposed to the elements. Rainwater can seep into the pores of the bricks, while constant sunlight can cause the surface color to gradually fade. Repeated wet-and-dry cycles can also accelerate changes in the condition of the brick surface.

2. Poor Air Circulation Leads to High Humidity

Areas with poor air circulation tend to be more humid because water that sticks to wall surfaces takes longer to dry. These conditions are ideal for moss growth, especially on walls located in shaded areas that rarely receive sunlight.

3. Dust and Dirt Build Up

Dust, dirt, smoke, and other debris that remain on the surface for too long can make the natural color of the bricks appear darker and duller. When mixed with water and moisture, this debris can also become even harder to clean off.

4. Lack of Maintenance and Cleaning

Exposed brick that has never been cleaned is more prone to dirt buildup. Minor issues such as damp stains or a thin layer of moss can also become more difficult to deal with if left untreated for too long.

5. Not Using Special Protection for Exposed Bricks

Without additional protection, bricks are directly exposed to water and moisture. Using the right coating for exposed brick can help reduce water absorption while preserving the surface’s appearance for longer.

Differences in the Maintenance of Exposed Brick for Indoor and Outdoor Use

The method for maintaining exposed brick walls should be tailored to their location. Bricks installed indoors are at a lower risk of weather exposure than those installed outdoors.

Mistakes to Avoid When Maintaining Exposed Brick 

Before learning how to care for exposed brick walls, Milanians should understand the mistakes to avoid when maintaining them, including:

• Allowing moss to grow for too long.
• Using a brush that's too rough.
• Using a cleaning agent that is not suitable for bricks.
• Spraying water at excessively high pressure without caution.
• Allowing the walls to remain damp at all times.
• Ignoring cracks on the surface or in the mortar joints.
• Applying the coating without cleaning the surface first.
• Applying a protective product that is not suitable for brick.

How to Care for Exposed Brick Walls to Prevent Them from Becoming Moldy and Dull Too Quickly 

1. Clean the Walls of Dust and Dirt Regularly

Start by cleaning the surface regularly using the appropriate method. Light dust can be removed with a soft brush or cloth, while heavier stains need to be treated with a cleaner that is safe for brick.

Don’t wait until the walls look very dirty. Regular cleaning is a simple yet effective way to maintain the appearance of exposed brick walls.

2. Avoid Excessive Moisture

Make sure the area around the wall has good air circulation and drainage. Do not allow water to pool or remain on the surface of the bricks.

For indoor walls, pay attention to areas that are often damp, such as near the bathroom or kitchen. As for outdoor walls, make sure rainwater does not pool directly on the wall’s surface.

3. Use a Special Coating for Maximum Protection

In addition to being cleaned, exposed brick can be given additional protection using a coating designed to help reduce water absorption. This protection is especially important for exterior walls that are frequently exposed to rain.

4. Repair Any Cracks in the Brick Walls Immediately

Cracks in bricks or wall joints should not be left unrepaired. These cracks can allow water to penetrate the material. The sooner they are repaired, the lower the risk that moisture will develop into a bigger problem.

5. Keep the Wall Area Dry

Keep unnecessary sources of water away from the brick surface. Make sure that gutters, downspouts, and the area around the wall are functioning properly so that water does not constantly come into contact with the brick surface.

6. If Mold Has Appeared, Clean It Immediately with a Specialized Cleaner

Any visible moss should be addressed immediately. Use a cleaner such as white vinegar, which is suitable for brick surfaces, and follow the usage instructions. After removing the moss, be sure to identify the source of the moisture to prevent the problem from recurring.
