How Does Floor Levelling Work?

Floor Levelling is the process of creating a smooth, even surface on a subfloor before installing new flooring. Whether you’re preparing for tiles, timber, vinyl, carpet, or epoxy coatings, proper levelling is essential for durability, appearance, and structural integrity. Here’s a detailed breakdown of how the floor levelling process works:

1. Initial Assessment

Before any levelling begins, professionals inspect the existing floor to determine the extent of unevenness and identify potential issues such as cracks, dips, high points, or moisture problems.

Laser or Spirit Levels: 
They are used to measure height variations across the floor.

Subfloor Type:
(concrete, timber, etc.) is evaluated to determine the best levelling compound or method.

This stage ensures that the correct materials and approach are chosen for a long-lasting result.

2. Surface Preparation

Proper surface preparation is critical for achieving a strong bond between the levelling compound and the subfloor.

Cleaning:
Dust, oil, paint, adhesives, and debris are thoroughly removed.

Grinding or scarifying:
High spots and surface contaminants are removed using industrial grinders.

Crack repair:
Cracks or holes are filled to prevent the levelling compound from seeping through.

Priming:
A bonding primer is applied to improve adhesion between the subfloor and the levelling compound.

A clean and stable base ensures the levelling product adheres properly and performs as intended.

3. Mixing the Levelling Compound

The levelling compound—often a self-levelling cement or latex-based mixture—is carefully mixed to the manufacturer’s specifications.

– It needs the perfect consistency to flow smoothly but still maintain strength.

– Professionals use mechanical mixers to ensure the mix is uniform, with no lumps or air pockets.

4. Application of the Levelling Compound

Once mixed, the compound is poured or pumped directly onto the prepared floor surface.

– The compound naturally flows and settles into low areas, filling dips and smoothing imperfections.

– Large areas may be trowelled or spread using spiked rollers to remove trapped air and create an even finish.

– For highly uneven floors, multiple layers may be applied after each layer has cured.

This stage is time-sensitive—technicians must work quickly to achieve a consistent finish before the compound begins to set.

5. Drying and Curing

After application, the floor must be allowed to dry and cure fully before any flooring materials are installed.

– Drying times vary depending on thickness, product type, temperature, and humidity—typically ranging from a few hours to a couple of days.

– During curing, the floor must be kept free from foot traffic, moisture, and dust.

6. Final Inspection

Once the levelling compound has cured, the floor is inspected for smoothness and evenness.

– Any minor imperfections are sanded or filled.

– A moisture test may be conducted to ensure the floor is ready for the next stage of installation.

When done correctly, the result is a perfectly level, smooth, and stable surface—ready for any type of new flooring installation.

Why Floor Levelling Is Important

Prevents Cracking or Shifting:
A properly levelled floor provides a stable foundation, reducing the risk of your new flooring cracking, warping, or shifting over time.

Enhances Appearance:
Level floors remove dips, bumps, and imperfections, giving your space a smooth, professional finish.

Ensures Proper Adhesion:
Flooring materials adhere better to a flat, even surface, preventing issues like gaps, bubbles, or uneven wear.

Extends Flooring Lifespan:
Addressing subfloor problems before installation helps your flooring last longer, protecting your investment and maintaining its quality.
