Can You Put Self-Leveling Compound on Bitumen

Self-leveling compounds are designed to level out imperfections in concrete floors. There are a few different types of self-leveling compounds, and they have different characteristics. It is a matter to discuss whether or not a self-leveling compound can be used on bitumen and what type of self-leveling compound is best to use.

When it comes to your bitumen, the self-leveling compound should be a big no-no. The self-leveling compound is designed for use on concrete, not bitumen. It will not adhere properly to bitumen and can even cause damage to the surface. In addition, the self-leveling compound is not designed to withstand the high temperatures that bitumen is exposed. It will quickly break down and degrade, leaving you with an uneven and unsightly surface.

Can Self-Levelling Compound Be Used on Bitumen

Can You Use Self-Leveling Compound on Bitumen?

The self-leveling compound is used to create a smooth, level surface. It is ideal for use on uneven or damaged surfaces and can be used on a variety of different materials, including bitumen.

But there are a few reasons why self-leveling compounds should not be used on bitumen. Bitumen is a petroleum product that is sticky and black in its natural state. It is often used as a waterproofing agent but can also be used in roofing and pavements. When bitumen is used in pavements, it is often mixed with aggregate to create a strong and durable surface.

A self-leveling compound can make it difficult for bitumen to adhere to surfaces, which can cause the bitumen to peel or flake off. The self-leveling compound can also make it difficult to apply a new layer of bitumen over the top of it, as the compound can prevent the bitumen from adhering properly.

What Are The Reasons behind Self-Leveling Compound Not Sticking on Bitumen?

You should better not use a self-leveling over bitumen flooring. The self-leveling compound should not be used on bitumen for a few key reasons.


The self-leveling compound is not compatible with bitumen and will not adhere properly. This means that it is not recommended to use a self-leveling compound as a means of repairing or leveling on bitumen surfaces.


The self-leveling compound is not designed to be used on bitumen and will not perform as intended. This is because the compound is not compatible with the bitumen, which can cause problems with the level of the surface.

Potential Damage

The self-leveling compound can actually damage bitumen, making it more susceptible to cracking and other damage. This is because the compound can seep into the bitumen, causing it to expand and contract. This can cause the bitumen to crack, which will then lead to further damage.

How Can You Make Self-Leveling Compound Stick on Bitumen?

If you still want to use a self-leveling compound on bitumen, there are a few things you should keep in mind.

Clean Surface

First, make sure that the surface of the bitumen is clean and free from debris. If it is not, sweep or hose it down until it is. If you’re screeding over bitumen, you need to make sure that the surface is completely clean and free of any debris. Any dirt or grit will just get trapped under the screed and create an uneven surface.

No Moisture

You also need to make sure that the bitumen is completely dry before you start. If there’s any moisture at all, it will just seep into the screed and weaken it. The cement will not adhere properly and could cause cracking or other issues down the way.

Watchful Application

Once you’ve prepared the surface, you can mix up your concrete or mortar and start screeding. Use a putty knife or similar tool, and apply a thin layer of self-leveling compound to the surface of the bitumen.

Once you have applied the self levelling over bitumen, use a roller or brush to spread it out evenly over the surface. Then, using a trowel or hawk, apply an even layer of cement over the bitumen surface. Be sure to go over any low spots multiple times so that they are filled in completely. Try to make this layer as even as possible.

Drying Time

Allow the self-leveling compound to dry for at least 24 hours before walking or driving on it. Letting the concrete cure will help to get it strong, and then you can apply the finishings if you want, such as tile or paint.

What Are The Benefits of Self-Leveling Compound?

When it comes to smoothing and finishing concrete floors, the self-leveling compound is often the material of choice. This is because a self-leveling compound can provide a number of benefits, including a smooth, level surface, increased durability, and resistance to staining and fading.

The self-leveling compound is ideal for both new construction and renovation projects. It can be used on a variety of surfaces, including concrete, wood, metal, and tile. It is also easy to apply and can be finished in a short amount of time. The smooth, level surface that the self-leveling compound provides is perfect for a variety of applications, including flooring, countertops, and walls.

How Many Types of Self-Leveling Compounds Are There?

There are two types of self-leveling compounds, latex-based and cement-based. Latex-based self-leveling compounds are made with a latex binder and aggregate. They are typically used indoors on wood, concrete, or terrazzo floors. Also, they are easy to use, provide a smooth finish, and are less likely to shrink than cement-based compounds.

Cement-based self-leveling compounds are made with a Portland cement binder and aggregate. They are typically used outdoors on concrete or asphalt floors. It is a little more difficult to use these than latex-based compounds, but they provide a stronger bond and are less likely to shrink.

How Does Self-Leveling Compound Help in Moisture Resistance?

Moisture-resistant self-leveling compounds are specially formulated to resist the effects of moisture and humidity. They’re perfect for use in areas where these conditions are present, such as bathrooms, kitchens, laundry rooms, and basements.

Moisture-resistant self-leveling compounds are typically made from a variety of different materials, including acrylics, silicones, and urethanes. These materials work together to create a barrier that prevents moisture from penetrating the surface.

This barrier also helps to prevent mold and mildew growth. There are many benefits to using a moisture-resistant self-leveling compound. They can help to extend the life of your floors by protecting them from water damage and can make your floors much easier to clean and maintain. Also, they can give your floors a smooth, level finish that looks great and is very durable.

What Can You Do to Seal Bitumen Floor?

For sealing bitumen floor, you’ll need to purchase a sealant specifically designed for this type of surface. Follow the instructions on the packaging to apply it evenly across the floor.


The floor must be completely clean and free of any dirt, dust, grease, or other debris. Any of these contaminants can prevent the sealer from bonding properly to the floor.


Once the floor is clean, a primer should be applied. This will help the sealer to adhere better to the floor and create a stronger bond. This will result in a longer-lasting and more durable finish.


When the primer is dry, the sealer can be applied. It is important to follow the manufacturer’s instructions for the best results. Be sure to seal any cracks or joints in the floor as well, to prevent moisture from seeping in and damaging the bitumen.

Top Coat

Once the sealer is dry, a top coat can be applied for extra protection. This will help to keep your floors looking shiny and new for longer.

While planning to level your floor, self-leveling compounds aren’t recommended for use directly on bitumen. If the compound does get under the bitumen and cause a hardening, it will be very difficult to remove.

Even if you need to use a self-leveling on bitumen in any case, make sure the surface is cleaned properly, and the bitumen is completely dry. Then apply with caution and give it enough time to dry. It can ensure a better result of the self-leveling compound on bitumen.
