How to Level a Floor with Concrete?

Published in Concrete Leveling 4 mins read

Leveling a floor with concrete involves a series of steps to ensure a flat and even surface. Here’s a detailed guide on how to achieve that, based on provided information:

Steps to Level a Concrete Floor

Here's how to level a floor using concrete, following a systematic approach:

  1. Identify the Low Spots:

    • The first crucial step is to locate areas on your floor that are lower than the rest. These are the spots that need to be built up with concrete leveling compound.

    • How to Identify Low Spots:

      • Use a long straightedge, like a level or a long piece of wood, placed on the floor.
      • Look for gaps or dips under the straightedge.
      • Mark these low spots with chalk or a marker.
      • Consider using a laser level for more accurate identification.

  2. Apply the Concrete Leveling Compound:

    • Once the low spots are identified, you can proceed with applying the concrete leveling compound.
    • This compound is typically a self-leveling mixture that flows to fill in the low areas, creating a flat surface.
    • Applying the Compound:
      • Prepare the compound by following the manufacturer's instructions.
      • Pour the mixture over the marked low areas.
      • Use a trowel or a squeegee to spread the compound evenly.
      • Be sure to blend the edges of the new layer with the existing floor.

  3. Leave it to Dry:

    • After applying the leveling compound, the crucial step is to let it dry and harden properly.
    • Drying times vary based on the product, temperature, and humidity. Always consult the manufacturer's guidelines.
    • Key points for drying:
      • Avoid walking on the wet leveling compound.
      • Keep the area free from drafts and direct sunlight.
      • Ensure the area is well-ventilated for proper drying.

  4. Finish with a Grinder (Optional):

    • If there are any high spots or minor unevenness after the compound has dried, a grinder can be used to smooth the surface.
    • When to Grind:
      • If the floor is slightly uneven after drying.
      • If you need a very smooth finish before sealing or applying epoxy.
      • Use a concrete grinder with the appropriate grit to smooth out the high spots.

  5. Seal the Floor / Install Epoxy:

    • To protect the leveled floor and enhance its longevity, it’s important to seal it.
    • Options for Finishing:
      • Apply a concrete sealer for moisture protection and stain resistance.
      • Install an epoxy coating, which provides a durable and aesthetically appealing finish.

Summary of the Leveling Process

Step Action Purpose
1. Identify Low Spots Locate uneven areas using a level and marking tools. To pinpoint areas needing leveling.
2. Apply Leveling Compound Prepare and pour concrete mix, spreading it evenly. To fill the low spots and create a level surface.
3. Leave to Dry Allow sufficient time for the compound to dry and harden. To ensure the leveling compound sets properly.
4. Grind (Optional) Smooth high spots using a concrete grinder if necessary. To fine-tune the floor for perfect smoothness.
5. Seal or Epoxy Protect floor using a sealant or apply a durable epoxy layer. To protect and enhance the leveled surface’s appearance and use.

By following these steps carefully, you can effectively level a floor with concrete, resulting in a flat, even, and durable surface.
