How to Level a Concrete Floor

Concrete is a highly durable material, making it a great option for things like patios, floors, and sub-floors. Concrete isn't indestructible, however, and over time can crack, crumble, and even sink if not installed properly. The good news about concrete is that it can be resurfaced, repaired, and leveled out if need be. See below for instructions on how to level out a concrete floor.

Prep Your Floors

  • Begin by removing everything from the area including baseboards, furniture, and any flooring currently on your concrete sub floor. You want a clear space to work with. The concrete leveling material you'll be using can get messy, so preparation is going to be key. Be sure to use drop cloths around the floor you are leveling to prevent getting any concrete material on other floors in or around your home. 
  • Go around your floor looking for any dips that need to be filled in. Also look for any areas that are higher such as mounds or ridges. These areas may need to be ground down before attempting to level the floors. If you have any areas such as this, think about renting a concrete grinding tool from your local tool rental store.

Prime Your Floors

Priming your floors is just as important as prepping them. Concrete leveler primer is used to help the leveling agent adhere to your floors better and will help prevent any issues with the existing concrete from ruining the leveling surface. Spread the concrete leveler primer over your floors using a push broom with soft bristles. Be sure to spread it evenly without leaving any puddles or pools of the material. Allow the primer to dry for a few hours before moving onto the next step. Read the manufacturer's directions for a more accurate time.

Level Your Floors

Mix the concrete leveling material according to the manufacturer's directions using a wheel barrow or a 5 gallon bucket and water. Once the mixture is prepared, use a squeegee or long-handled broom to spread the material around to cover your floors. Work from one side of the floor to the other, covering the entire surface. Spread it out evenly to cover and let it work it's magic. Allow the leveling agent to dry before attempting to walk across it. Read the manufacturer's directions for drying times, about 4-6 hours is enough time to be able to walk across it, but a longer curing time will be needed to be able to install new flooring, replace furniture, or drive across it.

Leveling your concrete floors is not exactly an easy task, but it can be done. Contact a concrete repair company like Crackerjack Mud Jacking Inc. for help with this if you aren't sure about taking on this job by yourself.
