Do Brick Sealants Work
Yes, brick sealants do work.
Bricks are porous and absorb moisture, which can lead to damage such as efflorescence.
Brick sealants effectively reduce water penetration, preventing problems like efflorescence and protecting walls, sheathing, and insulation.
They are easy to apply, maintain the color of the brick, and leave a natural appearance without flaking or peeling.
Did You Know?
1. Brick sealants are often made of siloxane or silane, which penetrate the porous surface of the brick and create a hydrophobic barrier.
2. Despite being commonly used to protect brickwork from water damage, brick sealants do not make the brick completely waterproof. They effectively repel water but still allow some moisture vapor to pass through.
3. Brick sealants can help prevent efflorescence, a white, powdery substance that forms on the surface of bricks when moisture evaporates and leaves behind salt deposits.
4. Using a brick sealant can also help prolong the lifespan of bricks by reducing wear caused by freezing and thawing cycles, as well as inhibiting the growth of mold and mildew.
5. Applying a brick sealant can potentially enhance the color and appearance of bricks, giving them a richer, more vibrant look. However, it is important to carefully choose the right type of sealant to avoid altering the natural texture and aesthetic of the brick.
The Porous Nature Of Mortar And Its Consequences
Bricks and Mortar: Understanding the Impact of Moisture
Bricks serve as essential building materials, finding various applications in construction, such as walls, stairs, and patios. To ensure their structural stability, cement mortar is used to hold the bricks together. However, it is crucial to recognize that both bricks and mortar are highly porous and readily absorb water and moisture.
The porous nature of mortar poses significant risks to the durability and integrity of brick structures. When water seeps into the mortar, it can infiltrate the walls, causing damage to the sheathing and insulation. Gradually, this water damage weakens the structural stability of the walls, necessitating expensive repairs.
Furthermore, the absorption of moisture by the mortar can lead to the development of efflorescence on the brick surface. Efflorescence is the residue of white powder minerals that remains after moisture evaporates from the bricks. Apart from affecting the aesthetic appeal of brick structures, it also serves as an indicator of potential ongoing water penetration issues.
Understanding The Detrimental Effects Of Water On Brick Structures
Water is one of the biggest enemies of brick structures. When water penetrates the bricks and mortar, it can cause a range of issues that go beyond mere aesthetics. The constant exposure to moisture can lead to the growth of mold, mildew, and fungus, which can cause health problems for the occupants of the building. Prolonged water penetration can also result in the deterioration of the brick itself, leading to cracks, crumbling, and erosion.
Additionally, water can seep into the wall cavities and damage the insulation, causing it to lose its effectiveness. This can result in increased energy consumption and higher utility bills. In regions that experience freezing temperatures, water penetration can be particularly problematic as it can freeze and expand within the bricks, leading to further structural damage.

Defeating Efflorescence With Brick Sealants
Efflorescence is a common problem on bricks, but it can be effectively controlled with the use of brick sealants. Brick sealants work by significantly reducing water penetration and creating a protective barrier that prevents moisture from entering the bricks.
By sealing the bricks, brick sealants effectively prevent efflorescence. This not only eliminates the unattractive white powder minerals but also addresses the root cause of water absorption. Brick sealants create a hydrophobic surface that repels water, safeguarding the bricks and mortar from water damage.
To summarize the benefits of brick sealants:
- Eliminates efflorescence
- Reduces water penetration
- Protects bricks and mortar from moisture.
The Easy And Effective Solution: Brick Sealing
Brick sealing is a simple and effective solution to protect brick structures from water penetration and the associated problems. The process of sealing bricks involves applying a high-performance penetrating sealer that is specifically designed for brick surfaces.
- The sealer is usually applied with a brush or sprayer and allowed to penetrate the surface of the bricks.
- Once applied, the sealer creates an invisible barrier that does not alter the natural appearance of the bricks.
- This means that the color and texture of the bricks remain unchanged, enhancing their aesthetic appeal.
Moreover, brick sealing provides long-lasting protection against water penetration. Unlike traditional sealants that can flake or peel over time, high-performance penetrating sealers bond with the brick surface, offering durable protection that can withstand the test of time.

Choosing High-Performance Sealers For Long-Lasting Protection
When considering brick sealants, it is important to choose high-performance products that offer long-lasting protection. These sealers are specifically formulated to penetrate deep into the brick, creating a strong and durable barrier against water infiltration.
High-performance sealers leave a natural appearance, ensuring that the beauty of the bricks is preserved without any flaking or peeling issues. They are designed to withstand harsh weather conditions, UV radiation, and other environmental factors, making them ideal for long-term protection of brick structures.
Brick sealants play a crucial role in preventing water penetration and combating issues such as efflorescence. By understanding the porous nature of mortar and the detrimental effects of water on brick structures, it becomes clear that sealing bricks is a necessary step to ensure their longevity and integrity. Choosing high-performance sealers further guarantees long-lasting protection and preservation of the natural beauty of bricks. So, if you are looking to protect your brick structures and enhance their durability, brick sealing is undoubtedly worth considering.

Frequently Asked Questions
Is sealing bricks a good idea?
Sealing bricks is generally not recommended due to the natural cavity in brick walls that allows for proper water drainage. The use of sealant can potentially trap moisture inside the bricks, leading to long-term damage. It is advisable to rely on the inherent design of brick walls and their ability to naturally drain water, rather than introducing additional sealing measures that may do more harm than good.
How long does brick sealing last?
The longevity of brick sealing can vary depending on several factors. While some brick and masonry sealers may have a lifespan of under 5 years, there have been instances where certain products have lasted for only 12 months. Factors such as weather conditions, maintenance, and the quality of the sealer used can significantly impact the durability of brick sealing. Regular inspections, maintenance, and reapplication of sealers can help ensure the longevity of brick sealing and protect the bricks from potential damage.
Does brick sealer stop damp?
Yes, brick sealer is an effective solution to prevent dampness on walls. By creating a protective barrier, it acts as a waterproof seal, preventing moisture from seeping into the bricks. This not only keeps the walls dry but also eliminates the risks of mold growth and structural damage caused by dampness. Additionally, the reduction in heat loss through wet walls can contribute to energy efficiency, resulting in potential cost savings in heating expenses. Furthermore, the easy-to-clean surface created by brick sealer significantly reduces the need for frequent and extensive cleaning, saving both time and maintenance costs. Overall, brick sealer proves to be a valuable solution for combating dampness in walls.
What is the best way to seal brickwork?
The optimal approach for sealing brickwork is by utilizing a breathable impregnating sealer. Unlike film-forming sealers, impregnators do not generate a surface coating or film. This particular type of sealer is most suitable for older structures with rubble-filled or solid brick walls, making it an ideal choice for sealing external brickwork while maintaining its breathability. By employing a breathable impregnating sealer, the brickwork remains protected without compromising the historical integrity of older buildings.
