To level an uneven concrete slab in a basement, you can use a self-leveling compound that contains Portland cement. Start by cleaning the existing slab with a degreaser before pouring the compound. Then lay a long, straight 2×4 wooden rail across the floor, with one end on the highest point. Use shims to level the rail and transfer the unevenness of the floor onto it with a scribing tool. Cut the rail along the scribed line with a circular saw and secure it to the slab with construction adhesive and masonry nails. Repeat this process with two more rails. Finally, mix the leveling compound to the consistency of thick batter using a drill with a mixing paddle, pour it inside the perimeter of the rails, and use a screed made from a straight-edged board to strike off the excess compound and create a smooth surface.
Self-leveling compound can only be used on a concrete floor that is out of level by 5mm or less. To determine if the floor meets this requirement, all existing flooring must be removed and the floor thoroughly cleaned. Drop a marble or golf ball in various places on the floor to see which way it rolls, indicating the lowest point. Use a long spirit level to measure the exact level of the floor, and if it is less than 5mm out of level, self-leveling compound can be used.
There are two types of self-leveling compound. The first type is a powder that is mixed with a latex liquid to form the compound. The second type is a bag of powder that already includes the latex compound and only needs to be mixed with water. The second type is easier to work with and can be used to level floors that are more than 5mm out of level by adding some sharp sand to the mix.
Self-leveling floor screed is a thin layer of compound that contains latex, allowing it to move without cracking. It is prepared by mixing it in a bucket using a mixing paddle attached to an electric drill. This ensures that the components are evenly distributed through the mixture.
Most latex compounds can be used with under-floor heating, but it is important to check the instructions that came with the heating kit to ensure compatibility.
Priming the concrete surface before laying self-leveling screed or compound can help reduce porosity, ensuring proper adhesion and a more even level.
