Floor Levelling Compounds

Our floor levelling compounds are designed to create smooth, level floors ready for most floor coverings, including vinyl, laminate, carpet, tiles and engineered timber. Whether you’re working on concrete floors, timber floors or mixed substrates, a high-quality levelling compound is essential for achieving a stable, durable base.

What floor levelling compounds are and how they work

A floor levelling compound is a cement-based or polymer-modified compound that flows across uneven floors to form a level surface. Once mixed with water to the right consistency, it spreads easily and fills low spots, helping to correct variations before installing new floor coverings.

These products are primarily intended for interior use and are suitable for preparation on concrete, screed and many existing substrates.

Self levelling compounds for smooth, even subfloors

A self levelling compound is formulated to spread naturally across the surface with minimal trowel work, saving time and helping you achieve a smooth, even finish. Self levelling products are ideal when you need a fast, efficient application and consistent results across large areas.

• Creates a uniform surface ready for laying floor finishes.
• Improves durability and long-term flooring performance.
• Provides a stable base that reduces future movement and cracking.

Choosing the right floor levelling compound for timber floors

Levelling over timber floors requires care to ensure the substrate is sound and compatible. Some products are designed specifically for timber overlays, offering improved flexibility and adhesion to help prevent movement-related issues.

Always follow the manufacturer's instructions and confirm that the levelling compound selected is suitable for the type of timber base you’re working with.

Levelling compounds compatible with underfloor heating

Many of our floor levelling compounds are compatible with underfloor heating systems. These products are formulated to retain strength while accommodating thermal expansion, helping to ensure a stable base that won’t crack under temperature changes.

Self levelling options are especially popular for underfloor heating because they fill voids efficiently and surround heating elements evenly for a more consistent heat output.

Where self levelling and floor levelling solutions are most effective

Levelling products are widely used across:

• Domestic and commercial interior projects.
• Smoothing uneven concrete floors.
• Preparing timber floors prior to renovation.
• Correcting dips, imperfections and uneven surface areas before installing new floor coverings.

Using a levelling compound is often the only reliable way to repair out-of-level floors and create a strong, consistent base.

Application steps that ensure a stable, level base

To achieve a high-quality result, careful preparation and correct mixing are essential. Standard application methods follow these steps:

• Clean and prime the substrate as required.
• Mix the levelling compound with water to the recommended consistency.
• Apply and spread using a trowel or pin roller.
• Allow to dry fully before walking on the surface (walk-on times vary by product).

This process helps ensure the floor levelling layer is sound, stable and ready for the next stage of installation.
