Self-levelling concrete is a product that is used to level concrete floors that are uneven. You can use self-levelling concrete by first preparing the floor surface for the concrete. Self-levelling concrete can then be mixed using the same methods as regular concrete. Once the concrete has been properly mixed, you will then need to pour it onto the floor before it begins to set or harden.
Clean the surface of the floor with a vacuum to remove any dirt and debris.
Add latex primer into a paint tray and use a roller to apply it to the floor. This will allow the self-levelling concrete to adhere to the floor.
Use a level to locate any low areas in the floor and mark the locations with a pencil. You will want to start with these areas.
Add 6 quarts of water into the bucket and add the self-levelling concrete mix. Follow the instructions on the package to properly mix the concrete.
Stir the self-levelling concrete mix with a power drill using a paddle attachment. Mix the concrete in the bucket for about four minutes or until the mixture is the consistency of pancake batter.
Pour the self-levelling concrete mix over the low areas you identified. Wait a minute or two for the mixture to spread out.
Smooth out the concrete using a trowel or a squeegee and then wait for the concrete to dry.
A cement mixer can also be used to mix the self-levelling concrete. You will be able to walk on the concrete after it has dried for at least four hours.
You will only have about 20 minutes of total work time to mix, pour and smooth out the concrete before it begins to set up.
