How to Level a Concrete Floor for Laminate Flooring Installation

Leveling a concrete floor before installing laminate flooring is essential to ensure a smooth finished surface and to prevent damage to your laminate. This guide walks you through the step-by-step process of preparing your concrete floor for laminate installation.

Materials Needed

Concrete self-leveling compound Primer (recommended for self-leveling compounds) Concrete grinder (if needed) Trowel or squeegee Mixing bucket and drill with a mixing paddle Leveling tool (level or straightedge) Protective gear (gloves, goggles, mask)

Steps to Level a Concrete Floor

Prepare the Area

Remove any furniture, carpets, or debris from the floor. Thoroughly clean the concrete surface to remove dust, dirt, and grease.

Inspect the Floor

Check for cracks, holes, or significant unevenness. Use a level or straightedge to identify low and high spots.

Repair Cracks and Holes

Fill any cracks or holes with a concrete patching compound. Allow it to cure according to the manufacturer’s instructions.

Grind High Spots

If there are high areas on the floor, use a concrete grinder to level them out. Be sure to wear protective gear during this process.

Apply Primer

Apply a concrete primer to the surface according to the self-leveling compound manufacturer’s instructions. This helps the compound adhere better.

Mix the Self-Leveling Compound

Follow the manufacturer’s instructions to mix the self-leveling compound. Use a drill with a mixing paddle to ensure a smooth consistency.

Pour the Compound

Start pouring the compound at the highest point of the floor and let it flow to lower areas. Use a trowel or squeegee to spread it evenly.

Level the Surface

Use a leveling tool to ensure the surface is even. You may need to work quickly as self-leveling compounds can set fast.

Allow to Cure

Let the compound cure for the recommended time before walking on it or installing laminate flooring. This usually takes 24 to 48 hours.

Check Levelness

Once cured, check the surface again with a level to ensure it’s flat. If necessary, you can apply a second layer of self-leveling compound.

Install Laminate Flooring

After the surface is fully cured and level, you can proceed with the installation of your laminate flooring.

Additional Tips

Always follow the manufacturer’s guidelines for the self-leveling compound you choose. Ensure the room is at a suitable temperature and humidity for the best results. Consider using a moisture barrier if the concrete is prone to moisture issues.

By carefully following these steps, you can create a level base for your laminate flooring, ensuring a professional-looking finish and longevity for your flooring.
