Self-levelling compound, also known as self-leveling concrete or self-leveling cement, is a type of concrete that is designed to flow and spread evenly over a surface, creating a smooth and level finish. This type of compound is commonly used in construction and renovation projects to level floors, countertops, and other surfaces.

What is Self-Leveling Compound Made Of?

Self-leveling compound is typically made of a mixture of cement, sand, water, and chemical additives. The additives help to improve the flowability, self-leveling properties, and drying time of the compound. Some compounds may also contain fibers or other materials to enhance their strength and durability.

How Does Self-Leveling Compound Work?

When applied to a surface, self-leveling compound flows and spreads out under its own weight, creating a smooth and even surface. The chemical additives in the compound help to control the flow rate and ensure that the compound levels out evenly. Once the compound has set, it forms a hard, durable surface that can be finished with various flooring materials, such as tile, hardwood, or carpet.

Benefits of Using Self-Leveling Compound

There are several benefits to using self-leveling compound in construction and renovation projects:

• Smooth and Even Surface: Self-leveling compound creates a smooth and even surface that is ideal for flooring applications. This can help to improve the appearance and functionality of a space.
• Easy to Apply: Self-leveling compound is relatively easy to apply compared to other flooring materials. It can be poured or spread over a surface and then leveled with a trowel or other tool.
• Fast Drying Time: Many self-leveling compounds have a relatively fast drying time, which can help to reduce project timelines.
• Durable and Long-Lasting: Self-leveling compound is a durable and long-lasting material that can withstand heavy foot traffic and other wear and tear.
• Cost-Effective: Self-leveling compound can be a cost-effective option for leveling floors and other surfaces, especially when compared to other methods such as resurfacing or replacing existing flooring.

Types of Self-Leveling Compound

There are several different types of self-leveling compound available, each with its own unique properties and applications. Some of the most common types include:

• Thin-Set Self-Leveling Compound: This type of compound is designed to be applied in thin layers, making it ideal for leveling minor imperfections in floors and other surfaces.
• Thick-Set Self-Leveling Compound: This type of compound can be applied in thicker layers, making it suitable for leveling larger unevenness or creating a raised floor.
• Bonded Self-Leveling Compound: This type of compound is designed to adhere to existing surfaces, making it ideal for leveling floors that are in poor condition.
• Unbonded Self-Leveling Compound: This type of compound is not designed to adhere to existing surfaces, making it suitable for creating a new floor surface.

Preparing the Surface for Self-Leveling Compound

Before applying self-leveling compound, it is important to properly prepare the surface.  It is also important to repair any cracks or damage in the surface.

Applying Self-Leveling Compound

To apply self-leveling compound, follow these general steps:

• Mix the compound: Mix the compound according to the manufacturer’s instructions.
• Pour the compound: Pour the mixed compound onto the prepared surface.
• Level the compound: Use a trowel or other tool to level the compound.
• Allow to dry: Allow the compound to dry completely before applying any finishes.

Finishing Self-Leveling Compound

Once the self-leveling compound has dried, it can be finished with various flooring materials, such as tile, hardwood, or carpet. It is important to follow the manufacturer’s instructions for the specific flooring material you are using.

Common Problems with Self-Leveling Compound

There are a few common problems that can occur when using self-leveling compound:

• Cracking: Cracking can occur if the compound is not applied correctly or if the surface is not properly prepared.
• Unevenness: Unevenness can occur if the compound is not leveled properly.
• Discoloration: Discoloration can occur if the compound is not mixed or applied correctly.

Troubleshooting Self-Leveling Compound Problems

If you experience problems with your self-leveling compound, there are a few things you can do:

• Contact the manufacturer: The manufacturer can provide guidance and troubleshooting tips.
• Hire a professional: A professional can help to diagnose and resolve problems with self-leveling compound.
• Re-apply the compound: In some cases, it may be necessary to re-apply the compound to correct problems.

FAQs About Self-Leveling Compound

Here are some of the most frequently asked questions about self-leveling compound:

How long does self-leveling compound take to dry? 

The drying time for self-leveling compound can vary depending on the type of compound and the environmental conditions. However, most compounds will dry completely within 24-48 hours.

Can I apply self-leveling compound over existing flooring? 

Yes, you can apply self-leveling compound over existing flooring, but it is important to prepare the surface properly before application.

How thick can I apply self-leveling compound? 

The thickness of the self-leveling compound will depend on the type of compound and the application. However, most compounds can be applied in layers up to 1 inch thick.

Can I apply self-levelling compound outdoors? 

Yes, you can apply self-leveling compound outdoors, but it is important to protect the compound from the elements during the drying process.

How much does self-leveling compound cost? 

The cost of self-levelling compound can vary depending on the type of compound, the quantity needed, and the location. However, it is generally a cost-effective option for leveling floors and other surfaces.

What are the alternatives to self-levelling compound?

Other options for levelling floors include resurfacing, patching, or replacing the existing flooring. However, self-leveling compound often offers a more efficient and durable solution.

Conclusion
