Leveling A Concrete Slab Floor

Leveling your concrete slab can be a helpful way to deal with flaws in the finish work. Although you may already have a professionally poured and finished slab, the nature of concrete can lead to a variety of issues later on. You may decide that you want a different look with a renovated floor covering, or you may want to improve the cosmetic appearance of your bare slab. In either case, floor leveling can be handled with a do-it-yourself approach if you have a little bit of time and patience.

Filling Cracks

Many slabs develop cracks. If you have minor cracks, you can use an epoxy to fill the gaps. If you have large cracks or breakage in your slab, you may want to consult with a professional concrete finisher about the issue. While you may be able to patch larger areas with cement, it's important to ascertain whether the cracks are still active, carrying the potential to spread further and cause additional damage. Although you may be able to handle the patchwork on your own, professional guidance may be especially important for avoiding damage to a hard floor covering like tile or wood.


A bonding agent is an important preliminary product before you apply your finish material. This will provide an appropriate surface with which the concrete leveling material can bond so that it stays in place once it hardens. You can consult with your bag of leveling material to determine the recommended primer for the product. This will ensure that you are using materials that are designed to complement each other, leading to less opportunity for the leveler to crack or fail. Use a long-handled paint roller for easy application of the material. Allow time for the agent to dry before moving on to the leveling process.

Mixing & Applications

It's important to select a high-quality, self-leveling underlayment so that you can count on reliable results. Reviews can provide you with helpful insight as to the reliability of a product. Look for both professional and amateur experiences to decide on your ideal material.

It's important to read the directions for mixing the material before you actually begin to combine ingredients. You may also want to tape off areas that are outside of your leveling zone so that the material doesn't move beyond the area being treated.

Assemble the tools and water required to create your mixture. Be precise with water measurements so that your material will set in a timely manner. Have your drill and paint mixing attachment ready. Use a corded drill so that you can obtain a consistent, smooth mixture without risk of losing battery power in the middle of the project. Mix the leveling product well, and pour onto the surface to be treated. You can use a long-handled squeegee to help the material to spread if you are treating a large surface. You can also use a hand trowel for spreading material in a smaller area. The self-leveling nature of the product, however, enables it to spread and dry with little additional attention. Allow your material to dry thoroughly before covering with any flooring materials.
