How To Apply Self-Leveling Concrete Over Brick

How to Apply Self-leveling Concrete over Bricks

Self-leveling concrete is a popular option for those looking to create a smooth, even surface for flooring or other applications. However, what many people may not realize is that self-leveling concrete can also be applied over brick surfaces. 

By using self-leveling concrete on brick, you can create a level surface that is perfect for laying tile or other types of flooring.

With proper preparation and application, self-leveling concrete can be a cost-effective and efficient solution for creating a smooth, level surface over brick. 

Yes, it is possible to put self-leveling concrete over brick. However, there are a few important factors to consider before proceeding with this application.

Firstly, the surface of the brick must be thoroughly cleaned and free of any debris, loose mortar, or other contaminants that may prevent the self-leveling concrete from properly adhering to the surface. This can be achieved by using a pressure washer or a wire brush to remove any loose material.

Secondly, it is significant to ensure that the surface of the brick is relatively level before applying the self-leveling concrete. Any large cracks or uneven areas may cause the self-leveling concrete to settle unevenly, resulting in an uneven finished surface.

Finally, it is recommended to use a bonding agent or primer before applying the self-leveling concrete. This will improve the adhesion of the self-leveling concrete to the surface of the brick and ensure a more even finished surface.

Preparing the Surface for Self-leveling Concrete

Before applying self-leveling concrete over bricks, it is essential to properly prepare the surface to ensure a smooth and level finish. This section outlines the steps involved in checking the condition of the bricks, cleaning the surface, and ensuring that it is level.

Checking the Condition of Bricks

The first step in preparing the surface for self-leveling concrete is to inspect the bricks for any cracks or damage. It is important to identify any areas that may require repair or replacement before proceeding with the application process.

Additionally, loose or uneven bricks should be identified and addressed to ensure a level surface.

Cleaning the Surface of Bricks

Once any necessary repairs have been made, the surface of the bricks should be thoroughly cleaned to remove dirt, dust, and debris. A power washer can be used to effectively remove any stubborn stains or buildup. It is important to allow the surface to dry completely before moving on to the next step.

Ensuring the Surface is Level

Finally, it is essential to ensure that the surface is level before applying the self-leveling concrete. If the surface is not level, it can result in an uneven finish.

A leveling compound can be used to address any low areas, while high spots can be sanded or ground down. It is important to follow the manufacturer’s instructions when using these products to achieve the best results.

Applying Self-leveling Concrete over Bricks

Mixing the Self-leveling Concrete

Selecting the Right Type of Self-Leveling Concrete: There are different types of self-leveling concrete available on the market, each with its own specific properties and recommended usage. Choose the one that is suitable for your project and follow the manufacturer’s instructions.

Mixing the Concrete with Water: Mix the self-leveling concrete powder with water as per the manufacturer’s instructions. It’s essential to get the right consistency for the concrete, and an incorrect water-to-powder ratio can lead to a subpar finish.

Pouring the Self-leveling Concrete

Starting at One End of the Surface: Start pouring the mixed concrete from one end of the surface to the other in a continuous flow to avoid stopping and starting, which can cause visible seams and an uneven surface.

Spreading the Concrete with a Trowel or Squeegee: Use a trowel or squeegee to spread the self-leveling concrete evenly. Avoid leaving any lumps or bumps, as these will be difficult to fix once the concrete dries.

Spreading the Self-leveling Concrete

Filling Low Spots and Gaps: While spreading the self-leveling concrete, you may find low spots or gaps that need to be filled. Fill these areas with more concrete, and use a trowel to smooth the surface.

Smoothing the Surface with a Self-leveling Tool: After spreading the concrete, use a self-leveling tool to smoothen the surface and remove any remaining lumps or bumps. The tool will help you achieve an even surface, making it easier to finish the concrete later on.

Finishing and Curing Self-leveling Concrete over Bricks

Smoothing the Surface of Self-leveling Concrete

After the self-leveling concrete has been poured, spread, and allowed to settle, it is time to smooth out any bumps or ridges on the surface.

Using a finishing trowel or squeegee, go over the entire surface of the concrete to create a smooth and level finish. Pay close attention to the edges and corners of the surface, as these areas can be more difficult to smooth out.

Allowing the Concrete to Dry and Cure

Once the self-leveling concrete has been smoothed out, it needs to be left alone to dry and cure. The length of time required for the concrete to dry and cure will depend on a variety of factors, including the type of concrete used, the temperature and humidity levels in the room, and the thickness of the concrete layer.

In general, self-leveling concrete should be allowed to dry for at least 24-48 hours before any additional work is done on the surface.

Curing the Concrete for Several Days

After the concrete has dried for 24-48 hours, it is important to continue to cure it for several days. Curing is the process of allowing the concrete to fully harden and strengthen, which can take up to a week or more. During this time, it is important to keep the surface of the concrete moist by regularly misting it with water or covering it with a plastic sheet. This helps prevent the concrete from cracking and ensures that it cures properly.

Applying a Finishing Coat to the Surface

Once the self-leveling concrete has fully dried and cured, it is ready for a finishing coat. There are several options for finishing the surface of self-leveling concrete, including sealing the surface with an acrylic sealer or applying a stain or paint. 

A sealer can help protect the surface from stains and damage, while a stain or paint can add color and style to the surface. Make sure to follow the manufacturer’s instructions for the finishing product carefully to ensure the best results.

Maintenance and Care for Self-leveling Concrete over Bricks

Regular Cleaning and Maintenance

To keep the surface of the self-leveling concrete over bricks clean and in good condition, it’s important to perform regular cleaning and maintenance. This will help to prevent dirt and stains from building up and keep the surface looking new for longer.

Sweeping or Vacuuming the Surface

Sweep or vacuum the surface of the self-leveling concrete regularly to remove dirt, dust, and debris. This will help to prevent scratches and other damage to the surface.

Mopping the Surface with a Neutral Cleaner

Mop the surface of the self-leveling concrete with a neutral cleaner to remove any remaining dirt or stains. Avoid using harsh chemicals or abrasive cleaners, as they can damage the surface.

Resealing the Surface of the Concrete

Over time, the surface of the self-leveling concrete may begin to wear or become damaged. To maintain its appearance and protect it from further damage, it’s important to reseal the surface periodically.

Inspecting for Cracks or Damage

Inspect the surface of the self-leveling concrete regularly for any cracks or damage. If you notice any cracks or other damage, repair it as soon as possible to prevent further damage.

Applying a New Coat of Acrylic Sealer

To reseal the surface of the self-leveling concrete, apply a new coat of acrylic sealer. This will help to protect the surface from water damage, stains, and other types of damage. Be sure to follow the manufacturer’s instructions for applying the sealer.
