Are you planning to install new flooring in your home or commercial space, but the concrete subfloor is uneven or has dips and bumps? Don't worry; leveling a concrete floor is not as complicated as it may seem. In this blog, we'll discuss the steps you can take to level a concrete floor and prepare it for new flooring installation.

Step 1: Inspect the Concrete Floor

The first step is to thoroughly inspect the concrete floor to identify the areas that need leveling. Look for cracks, dips, bumps, and uneven areas that are more than 1/4 inch in height difference. Mark these areas using a chalk line or painter's tape so that you know where to focus your attention during the leveling process.

Step 2: Prepare the Surface

Before starting the leveling process, ensure that the concrete floor is clean and free from debris. Sweep and vacuum the surface, removing all dirt, dust, and loose particles. It's also essential to repair any cracks or holes in the concrete using a patching compound.

Step 3: Choose a Leveling Compound

There are various leveling compounds available in the market, and the choice of compound will depend on the extent of leveling required, the type of new flooring being installed, and the budget. Self-leveling compounds are the most popular as they are easy to apply and spread themselves over the surface.

Step 4: Mix the Compound

Follow the instructions on the leveling compound package to mix it properly. Some compounds require water, while others require mixing with a specific type of liquid. Mix the compound in small batches to ensure it doesn't dry before application.

Step 5: Apply the Compound

Starting at the furthest corner of the room, pour the leveling compound onto the concrete surface, spreading it evenly with a trowel or a gauge rake. Work quickly and methodically, ensuring that you apply the compound to the marked areas first. Avoid stepping on the compound while it's wet to prevent creating footprints.

Step 6: Smooth and Level the Compound

After applying the compound, use a smoothing tool or a steel trowel to even out the surface. Ensure that the compound is level and smooth, especially at the edges of the marked areas. Allow the compound to dry according to the manufacturer's instructions.

Step 7: Sand the Surface

Once the compound has dried, sand the surface with a pole sander or a hand-held sander to remove any high spots or bumps. Ensure that the surface is smooth and level before proceeding to install the new flooring.

In conclusion, leveling a concrete floor requires careful planning and execution, but it's a necessary step to ensure that your new flooring looks and performs at its best.
