Uneven floors can cause problems when installing tiles, vinyl, carpet or other floor covering materials such as poorly fitting flooring and visible flaws. Over time, regular foot traffic may create more issues.
Learning how to level an uneven floor properly is an important step in many flooring projects. By using the right floor levelling compound, you can fix dips and low spots, creating a smooth base for new floor coverings
At Peppard Building Supplies, we stock Dunlop LX-40 Floor Leveller. A reliable levelling compound for interior floors in dry areas.
This floor leveller is ideal for smoothing surfaces. It works on concrete floors, cement sand screeds, terrazzo, and quarry tiles. It helps installers create a strong, level base before fitting a new floor covering.
Uneven floors can happen in older properties where the screed has worn unevenly and in refurbishment projects when old flooring is removed during building work.
Modern floor levelling compounds correct these irregularities. Once applied, the levelling compound spreads over the surface and fills low spots. It helps level the concrete floor and prepares it for the laying and installation of finished floor coverings.
Products like Dunlop LX-40 Floor Leveller create a smooth, reliable surface. They also keep the strength needed for long-term performance.
Before applying the Dunlop LX-40 Floor Leveller, proper preparation of the subfloor is essential.
The surface must be dry, stable and free from dust, grease or debris. This ensures the levelling compound bonds correctly with the substrate and produces a professional finish.
If the floor is in direct contact with the ground, the subfloor should include a damp proof membrane to prevent moisture affecting the levelling compound. This may mean the subfloor needs to be taken up and re-laid using a proprietary damp proof membrane. Moisture issues can cause levelling products to fail or reduce their long term performance.
Surfaces such as cement sand screeds and concrete should be primed before applying the leveller. A primer helps improve adhesion and ensures the levelling compound spreads evenly.
Taking the time to prepare the subfloor properly will make the levelling process much more effective.
The step-by-step process below explains how to use Dunlop LX-40 Floor Leveller. It helps correct uneven floors and prepare the surface for new flooring.
Begin by checking the floor with a spirit level to find low spots or areas that need fixing. This helps determine the thickness required when applying the levelling compound.
Next, prime the floor using an SBR bonding agent diluted with water at 1:4. Allow the primer to dry fully before starting the levelling process.
Once the surface is ready, the levelling compound can be mixed. Add one 20 kg bag of Dunlop LX-40 Floor Leveller to 3.8 litres of clean water. Mix the product using an electric drill with a paddle mixer until it forms a smooth mortar.
Allow the mixture to stand for around 2 minutes, then remix for 30 seconds. This gives a workable pot life of approximately 30 minutes depending on temperature and site conditions.
You can now pour the mixture directly onto the floor and smooth it over the area with a steel trowel. While applying the self-levelling compound, move steadily across the surface so it flows into dips and fills any low spots.
You can then use a spiked roller to remove trapped air and help create a smooth surface across the floor.
One of the advantages of Dunlop LX-40 Floor Leveller is the relatively quick curing time.
Under normal conditions, you can walk on the surface after about 4 hours. Light foot traffic is possible once the leveller has hardened.
You can typically install ceramic tiles after around 4 hours, depending on temperature and site conditions.
For other floor coverings, like vinyl or carpet wait a minimum of 24 hours before installation. To allow the Dunlop LX-40 to fully cure and ensure flooring adhesive bonds correctly.
