What Is a Floor Levelling Compound?
A floor levelling or floor screeding compound is a fast-setting mixture designed to smooth out bumps, dips, and slopes on subfloors. Typically composed of cement, polymer, and various additives, it flows and spreads evenly. Once poured, it settles into low spots, creating a level surface ideal for installing finished flooring.
This product is effective on concrete, timber, and even tiled subfloors. Many professionals prefer it over manual methods because it is faster, more accurate, and reduces the risk of future problems caused by uneven surfaces.

Benefits of Starting with a Level Subfloor
Flooring materials require solid support underneath. If the subfloor is sloped or cracked, tiles can shift, laminate boards may buckle, and carpets may wear out quickly. By using a proper concrete floor leveling product, you ensure stability, comfort, and safety.
For those installing radiant heating systems, self-levelling compounds are particularly beneficial. They flow around heating cables or pipes, covering them evenly and enhancing heat distribution.
Tools and Supplies that Professionals Use
Professional floor levelling experts rely on specific tools to ensure precise, clean, and long-lasting results. These tools are not just for convenience; they help achieve a smooth surface and prevent common levelling issues like air bubbles, poor bonding, or uneven spread.
Here’s what experienced installers keep on hand:
Self levelling compound or self levelling screed – Chosen based on the subfloor material and the required thickness.
High Speed Heavy-duty mixing paddle and bucket – Ensures a lump-free, consistent blend that flows properly.
Graduated water container – Accurate water measurement is key to maintaining the right mix ratio.
Wide trowel or floor smoother – Used to help guide the compound evenly across the surface.
Spiked roller – Removes trapped air that can cause surface flaws or bonding failure.
Bonding primer – Applied before pouring to improve adhesion and prevent premature drying.
Edge damming materials (foam strips, painter’s tape) – Used to seal doorways and edges, keeping the product in place.
High-suction vacuum – Cleans dust and debris from the subfloor to ensure strong bonding.
Professional Floor Levelling Process
Step 1: Inspect and Clean the Subfloor
Professionals begin by checking for cracks, moisture, or weak spots in the subfloor. Any damage is patched using approved fillers. The surface is then vacuumed thoroughly. Clean, dry, and solid subfloors are essential before applying any levelling compound.
Step 2: Apply a Primer
Primer is rolled or brushed onto the subfloor to improve grip. It prevents early drying and helps the compound bond without lifting. Experts choose the right primer for the surface type—timber, tile, or concrete—based on manufacturer instructions.
Step 3: Mix the Levelling Compound
Using a mixing drill, the compound is blended with the exact amount of water until smooth. Professionals mix in batches they can pour immediately. Timing is critical; most self-levelling compounds start setting in less than 20 minutes after mixing.
Step 4: Pour and Spread the Compound
The compound is poured onto the primed surface and guided using a wide trowel. It spreads evenly, filling dips and smoothing high spots. For large areas, teams work in sequence to maintain a continuous, level surface while keeping a wet edge.
Step 5: Let It Cure
After application, the floor is left undisturbed for the curing period. Most compounds dry within hours, but professionals allow at least 24 hours before installing any flooring. Walking too soon on uncured areas risks dents, cracks, or an uneven finish.
Common Mistakes to Avoid
Skipping the primer: This weakens adhesion and leads to peeling.
Wrong water ratio: Too much water makes the mix runny and weak.
Working too slowly: These products set quickly; prep in advance.
Poor cleaning: Dirt, grease, or paint will prevent bonding.
Using the wrong product: Always match the compound to your subfloor.
Choosing the Right Product
There are many concrete floor leveling products available, and not all are the same. Some are made for thin layers, while others handle depths up to 50mm or more. Look for features like:
Quick-drying or rapid-set formulas
Compatibility with radiant heating
Low shrinkage to reduce cracking
Polymer-modified blends for flexibility and strength

Creating Long-Lasting Results
Using a floor levelling compound correctly can extend the lifespan of your flooring and reduce the need for repairs over time. It helps prevent creaks, provides a smoother finish, and ensures tiles or planks fit better. A level subfloor is always crucial before installing any flooring.
In regions like Queensland, where climate and subfloor types vary, it's wise to partner with companies that understand local conditions.
Screedflow Australia offers both advanced materials and expert installation. With their team of screeding and levelling experts, you receive high-speed service and lasting results for every kind of surface, catering to residential, commercial, and industrial buildings.
Conclusion: Elevate Your Flooring Projects
In conclusion, understanding the importance of a level subfloor cannot be overstated. It is the foundation for any successful flooring project. By utilizing the right tools, techniques, and products, you can ensure that your flooring not only looks great but also performs well for years to come. Whether you are a builder or a renovator, investing in quality floor levelling solutions will pay off in the long run.
