Brick sealer, often called masonry sealer or brick sealant, is a water seal applied to brick, stone, or concrete walls to produce a waterproof surface. This is accomplished through the process called brick sealing.

Here are the latest techniques used for brick sealing:

1. Nano-sealing


Modern brick sealing methods like nano-sealing offer long-lasting protection against moisture-related issues. This method uses nanotechnology to coat the brick's surface with a barrier that keeps water from reaching the surface.

Nano-sealing helps stop moisture-related issues like mold growth and water damage. Additionally, leaving the brick's texture and color alone helps to preserve the brick's natural appearance.

This technique benefits older or historic structures when maintaining the original look is crucial. See a specialist to determine if nano-sealing is the best option for your brick-sealing needs.

2. Silane or siloxane sealer

Silane or siloxane sealer is a widely used method for sealing bricks without affecting the brick's appearance. It offers excellent water repellency. By penetrating the brick's surface and creating a water-repellent barrier, the transparent liquid sealer used in this technique stops water from penetrating the brick's pores.

Among the many types of sealers on the market, silane or siloxane sealer is one of the most durable and long-lasting solutions to prevent problems caused by moisture, such as mold growth and water damage.

This technique can be used on all types of bricks as a cost-effective solution to protect your property from moisture-related problems. As a result, it is a viable option for homeowners looking to protect their property from moisture-related issues.

3. Acrylic sealer

For brick sealing, acrylic sealer is a technique widely used to seal the surface of the brick. It provides a protective coating on top of the brick, making it resistant to corrosion and preventing water from penetrating the surface.

This technique involves coating the brick with a transparent, impervious film made of an acrylic-based sealant. An acrylic sealer is an excellent option for homeowners searching for a low-cost way to protect their bricks against mold growth and water damage. It is also perfect for giving the brick a glossy appearance while improving its color and texture.

4. Polyurethane sealer

A popular technique for sealing bricks is using a polyurethane sealer. This technique helps to create a waterproof layer on the surface of the brick and keeps water from penetrating it. It also uses a polyurethane-based sealant that is great for patios, pathways, and driveways because of how much traffic they receive around the house.

In addition to offering excellent protection against moisture-related issues, including mold growth and water damage, polyurethane sealer is solid and durable. Various treatments, including matte, satin, and high gloss, are also offered.

Why You Should Consider Brick Sealing

You need brick sealing even if your bricks seem waterproof. This is because natural mineral surfaces like stone and brick can absorb moisture. After all, they are porous. Several problems can happen as a result which is why you still need brick sealing.

Here are additional reasons why you should employ any of the brick-sealing techniques mentioned.

Structural damage

If moisture is allowed to penetrate walls, it can cause significant damage. The concrete, stone, or brick wall may experience a freeze-thaw cycle if moisture penetrates it. This will cause the water to expand. When the moisture expands, it exerts pressure on the surface of the brick and causes spalling.

Spalling is breaking or chipping away a material's surface, such as concrete or masonry, due to pressure, temperature changes, or other external factors. It is a common problem in construction and can lead to the deterioration of the structure. Brick sealing will help prevent this and further issues.

Damp problems

As with cavity walls, dampness is an issue for solid wall buildings. The inside wall of the house may also be affected by moisture that seeps into the outer wall. Since only one wall is in a solid design, moisture can quickly enter the home's interior.

This cavity wall cavity structure aims to stop moisture from moving through it. Poorly installed insulation may also result in damp issues if unfilled mortar joints, debris, and wall ties covered in mortar provide a pathway for moisture to enter the house's interior.

Aesthetics deterioration

Your home's curb appeal can be affected if moisture penetrates an external wall. In addition to the damage that cracking will do to the bricks, moisture will also cause other issues, including brickwork discoloration and widespread green growth, moss, and lichen. All these can thrive on wet external walls. The curb appeal of your house will be significantly affected by these.

When it comes to moisture, salt efflorescence can also be a common issue. The salt in the masonry causes this to appear as a white, powdery deposit on concrete, stone, and brick walls. When water infiltrates the masonry, it dissolves the salts within, which later move out of the wall when the water evaporates.


When sealing your bricks, you need to choose the right system depending on the type of brick, the amount of moisture present, and the weather conditions. The latest techniques for brick sealing have been discussed, and you can consult a professional to help determine the best one for your needs.
