Which Self-leveling compound to use

If you’re planning on installing new flooring, it’s important to ensure that the subfloor is level and smooth. A self-leveling compound can help achieve this by filling in any low spots and creating a level surface for the new flooring to be installed. However, with so many different self-leveling compounds available on the market, it can be difficult to know which one to choose for your specific project needs. In this comprehensive guide, we’ll take a closer look at the different types of self-leveling compounds and help you understand which self-leveling compound to use for your next flooring project.

Types of Self-Leveling Compounds:

Cement-Based Self-Leveling Compounds:

Cement-based self-leveling compounds are the most commonly used type of self-leveling compounds. They are typically made from a blend of Portland cement, fine aggregates, and other additives. These compounds are ideal for use on concrete subfloors and are compatible with most types of flooring, including tile, hardwood, and carpet.

Gypsum-Based Self-Leveling Compounds:

Gypsum-based self-leveling compounds are made from a blend of gypsum powder and other additives. These compounds are ideal for use on wood subfloors and can be used with most types of flooring, including vinyl, linoleum, and carpet. Gypsum-based compounds are not recommended for use on concrete subfloors.

Hybrid Self-Leveling Compounds:

Hybrid self-leveling compounds are a combination of cement-based and gypsum-based compounds. These compounds offer the benefits of both types of compounds and are ideal for use on a variety of subfloors, including concrete and wood.

Best Overall Self-Leveling Underlayment:

When it comes to the best overall self-leveling underlayment, a cement-based compound is usually the top choice. It’s versatile and can be used on various subfloors, including concrete, wood, and even some types of existing flooring. Additionally, cement-based compounds are typically stronger than gypsum-based compounds, making them a good choice for high-traffic areas. Some popular options for the best overall self-leveling underlayment include Ardex Feather Finish, Mapei Self-Leveler Plus, and Custom Building Products LevelQuik RS.

Best Self-Leveling Compound for a Concrete Floor:

If you’re working with a concrete subfloor, a cement-based self-leveling compound is typically the best choice. Cement-based compounds can bond well to concrete and are ideal for leveling out any uneven areas. One popular option for the best self-leveling compound for a concrete floor is Henry 555 LevelPro, which is a fast-drying, high-strength compound that can be applied up to 1 inch thick.

Best Self-Leveling Compound for a Flat Surface:

If you’re looking to create a perfectly flat surface, a gypsum-based self-leveling compound is typically the best choice. Gypsum-based compounds have excellent self-leveling properties and can be used to create a smooth surface with minimal effort. One popular option for the best self-leveling compound for a flat surface is USG Durock Brand Quikrete Self-Leveling Underlayment, which is designed to provide a smooth and level surface for tile and other types of flooring.

Best Self-Leveling Compound for Indoor Floors:

When it comes to indoor floors, a cement-based self-leveling compound is typically the best choice. Cement-based compounds are strong and can be used with a wide range of flooring types, making them ideal for indoor flooring projects. One popular option for the best self-leveling compound for indoor floors is Laticrete NXT Level, which is a fast-drying and high-strength compound that can be used on a variety of subfloors.

Best Easy-to-Use Self-Leveling Compound:

If you’re looking for a self-leveling compound that’s easy to use, a pre-mixed compound is usually the best option. Pre-mixed compounds don’t require any measuring or mixing, making them ideal for DIYers or those who are new to self-leveling compounds. One popular option for the easiest-to-use self-leveling compound is DAP Presto Patch, which is a pre-mixed compound that can be used to level floors, walls, and other surfaces.

Best Inexpensive Self-Leveling Compound:

If you’re on a budget, a gypsum-based self-leveling compound is typically the most inexpensive option. Gypsum-based compounds are typically less expensive than cement-based compounds, making them a good choice for those looking to save money on their flooring project. One popular option for the best inexpensive self-leveling compound is Custom Building Products LevelQuik RS, which is a gypsum-based compound that can be used on both concrete and wood subfloors.

Factors to Consider When Choosing a Self-Leveling Compound:

Subfloor Type:

The type of subfloor you have will play a significant role in determining which self-leveling compound to use. If you have a concrete subfloor, a cement-based self-leveling compound would be the best choice. If you have a wood subfloor, a gypsum-based self-leveling compound would be more appropriate.

Thickness:

The thickness of the self-leveling compound will depend on the depth of the low spots in your subfloor. Cement-based compounds can be applied in thicker layers than gypsum-based compounds, making them a better choice for deeper low spots.

Drying Time:

Drying time is another important factor to consider when choosing a self-leveling compound. Cement-based compounds typically take longer to dry than gypsum-based compounds. Hybrid compounds offer a faster drying time than cement-based compounds and a longer drying time than gypsum-based compounds.

Substrate Condition:

Before choosing a self-leveling compound, it’s essential to assess the condition of the substrate. If the substrate is damaged or contaminated, it may not bond well with the self-leveling compound. In such cases, it’s crucial to repair or clean the substrate before applying the self-leveling compound.

Moisture Content:

Moisture can also impact the performance of self-leveling compounds. Excess moisture can cause the compound to crack or fail, while too little moisture can affect the bonding process. It’s important to ensure that the substrate and the self-leveling compound are at the appropriate moisture levels before installation.

Overall, when choosing a self-leveling compound, it’s crucial to consider factors such as substrate condition, thickness, drying time, and moisture content. By taking these factors into account, you can ensure that you choose the best self-leveling compound for your project, and achieve the desired results.

Conclusion:

Choosing the right self-leveling compound is essential for achieving a smooth and level surface for your flooring project. When choosing a self-leveling compound, consider factors such as the type of subfloor you have, the thickness of the compound, and the drying time. By understanding which self-leveling compound to use for your specific project needs, you can ensure that your flooring project is a success.
