How to Use Levelling Compounds

You can use levelling compound on various substrates, from concrete, wood and asphalt to existing tiles. For areas where the floor dips or has holes in it, this is exactly what you need.

Self-levelling concrete has high flow characteristics; therefore, you will not need to keep adding water to it throughout the application process. Aptly named, it naturally works itself into the areas to create a smooth, level surface. All you need is gravity!

Before levelling, the substrate must be clean, dry and free of dust and other residues that will prevent your leveller from properly adhering. Existing floor paints and old flooring adhesives may also hinder the bonding process, so be sure to have these removed prior to application.

The powder and water ratio must be monitored and controlled when mixing your levelling compound. Too much moisture will affect the surface finish and your leveller will take longer to set. Pour the recommended amount of cold water into a bucket and gradually add your levelling powder while mixing until you achieve a lump-free consistency.

When pouring your leveller, it is always wise to start at the furthest point in the room and work backwards to avoid walking through the wet product. Using a spiked roller with removing any trapped air bubbles, which can affect the finished surface, or even cause cracking later down the line.

Bear in mind when allowing your leveller to dry that cold, damp or humid areas with poor airflow can delay the process. Try to prevent drafts and direct sunlight getting to the leveller as this runs the risk of ‘force drying’ the product, causing excess tension and cracking.
