However, there are some cases where sealing exterior bricks may be beneficial. For instance, in areas with severe weather conditions or high levels of pollution, sealing can provide an extra layer of protection against moisture penetration and staining. Additionally, older or more porous bricks may benefit from sealing to prevent water damage. It’s important to assess the specific needs of your brickwork and consult with a professional before making a decision.

Should Exterior Brick Be Sealed?

Sealing exterior bricks is a topic that’s sparked much debate among homeowners and construction professionals. Ultimately, the decision to seal exterior bricks depends on several factors, including climate, brick type, and personal preference.

First and foremost, it’s important to note that modern bricks are incredibly durable and resistant to weathering. Unlike older bricks, which were more porous and susceptible to water absorption, contemporary bricks are manufactured using advanced techniques that make them less likely to be damaged by moisture. Additionally, improvements in mortar composition have resulted in stronger and more watertight joints, further reducing the need for sealing.

In wet and humid environments, where bricks are constantly exposed to rainfall and high levels of moisture, sealing can provide an extra layer of protection against water intrusion.

The type of brick also plays a significant role in the decision-making process. Different bricks have varying levels of porosity, with some being more prone to water absorption than others. For example, clay bricks are generally more porous than concrete bricks.

Therefore, it’s crucial to ensure that exterior brick is able to “breathe” in order to expel any trapped moisture and prevent damage to the structure.

Does Exterior Brick Need to Breathe?

Exterior brick needs to breathe in order to maintain it’s integrity and prevent damage over time. When moisture becomes trapped between the brick and paint layers, it can lead to detrimental effects. For instance, during colder weather, the trapped moisture can freeze and expand, causing the layers to crack and chip. This expansion and contraction cycle can gradually erode the exterior brick and mortar, compromising the structural stability of the building.

Brick naturally absorbs and releases moisture, which helps regulate it’s moisture content. Additionally, the airflow helps to dry out any moisture that does accumulate, preventing it from becoming trapped and causing further harm.

In contrast, applying impermeable coatings, such as sealants or non-breathable paints, can hinder the bricks ability to breathe. These coatings create a barrier that prevents moisture from evaporating properly, leading to increased moisture levels and potential long-term damage. It’s essential to choose breathable paints and coatings specifically designed for use on exterior brick surfaces to ensure proper moisture management.

This can be achieved by ensuring there are appropriate ventilation systems and by keeping vegetation and clutter away from the exterior brick.

Regular maintenance and inspection are crucial in preserving the longevity of exterior brick. Periodically checking for signs of moisture damage, such as efflorescence (white powdery substance), moss growth, or deteriorating mortar, can help identify potential issues early on. Promptly addressing any signs of moisture infiltration or damage can help prevent further deterioration and preserve the breathability of the brick.

In addition to the risk of fire spreading quickly on brick surfaces, there’s another concern related to exposed brick. Chris Alexakis, a building contractor, emphasizes the potential danger posed by the flammable materials used in the mortar joints between bricks. These materials, such as sawdust or sand, can act as fuel if the brick becomes exposed to a fire. Therefore, it’s crucial to assess the safety aspects before considering exposed brick as a design feature.

Is Exposed Brick Safe?

Exposed brick has long been a popular design trend, adding a charming and rustic touch to homes and commercial spaces. However, concerns about it’s safety have also arisen. Fire, in particular, presents a significant risk on brick surfaces. Building contractor Chris Alexakis has cautioned against this danger, emphasizing how the mortar joints between the bricks, containing potentially flammable materials like sawdust or sand, can act as fuel in the event of a fire.

Reactive protective coatings can also be applied to exposed brick, acting as a barrier to prevent fire from reaching the bricks themselves. These coatings are designed to withstand high temperatures, thwarting the propagation of fire and safeguarding the bricks beneath. Regular inspection and maintenance of the coatings are necessary to ensure their continued effectiveness.

Additionally, adherence to local building codes and regulations is crucial when considering exposed brick. Consulting with professionals, such as building contractors or fire safety experts, can provide valuable guidance on ensuring the safety of exposed brick installations.
