A Complete Guide to Self-Levelling: Everything You Need to Know
When it comes to flooring, achieving a smooth and level surface is crucial for both aesthetics and functionality. Uneven floors can lead to problems such as improper tile installation, gaps in wood flooring, and even structural issues. This is where self-levelling comes into play. Whether you’re a homeowner looking to renovate or a contractor working on a commercial project, self-levelling is an essential technique to understand.
What is Self-Levelling?
Self-levelling refers to the process of using a self-levelling compound (SLC) or self-levelling screed to create an even and uniform surface on a subfloor. These compounds are specially formulated mixtures that spread easily and settle into place, eliminating surface irregularities.
Unlike traditional cement, which requires manual smoothing, self-levelling compounds flow freely and level themselves out, making the process faster and more efficient.
Benefits of Self-Levelling
Smooth and Even Surface — Self-levelling compounds provide a flawless base for tiles, vinyl, laminate, and other flooring materials.
Time-Saving — The quick-drying properties of these compounds reduce downtime during construction or renovation.
Enhances Durability — A properly levelled surface ensures the longevity of the flooring material installed on top.
Minimizes Floor Defects — Prevents cracks, hollows, and gaps that could lead to premature wear and tear.
Suitable for Various Flooring Types — Works well with concrete, plywood, and existing tile surfaces.
Types of Self-Levelling Compounds
Self-levelling compounds come in different types, each suited for specific applications:
- Cement-Based Self-Levelling Compound — Ideal for interior floors and commonly used for commercial and residential projects.
- Gypsum-Based Self-Levelling Compound — Often used in situations where moisture sensitivity is a concern, such as underfloor heating systems.
- Polymer-Modified Self-Levelling Compound — Provides added flexibility and strength, making it ideal for high-traffic areas.
How to Apply Self-Levelling Compound
Applying a self-levelling compound requires careful preparation and execution. Here’s a step-by-step guide:
Prepare the Surface — Clean the floor thoroughly, removing dust, dirt, and grease. Repair any cracks or holes in the existing surface.
Apply a Primer — Priming the floor ensures better adhesion and prevents moisture-related issues.
Mix the Self-Levelling Compound — Follow the manufacturer’s instructions to mix the compound with water, ensuring the right consistency.
Pour and Spread — Pour the mixture onto the floor and use a gauge rake or trowel to help it spread evenly.
Let It Settle — The compound will level itself naturally. Avoid disturbing it during the curing process.
Allow Proper Drying Time — Depending on the product used, drying time may vary from a few hours to a full day.
When to Use Self-Levelling?
Before installing tiles, laminate, or hardwood flooring
When fixing uneven concrete floors
In commercial spaces where high precision is required
For repairing damaged or old subfloors
Final Thoughts
Self-levelling is a game-changer in flooring projects, offering a hassle-free way to achieve smooth and durable surfaces. Whether you’re a DIY enthusiast or a professional contractor, understanding the right type of self-levelling compound and its application process will ensure excellent results. Investing in Self-levelling Dubai not only improves the aesthetics of your space but also enhances the longevity of your flooring.
