Seal the Crack
The first part of repairing the cement slab is to seal any cracks to prevent them from spreading up into the new layer of concrete that you will use to level the surface. A caulking gun loaded with either a tube of concrete repair or polyurethane sealant will do.
Clean the Slab
Before you can continue any further, make sure that the concrete slab is immaculately clean. Any dirt or residue will prevent the leveler from adhering, which will result in a cracked and uneven concrete slab in the future. Vacuum the pad using a wet/dry vacuum. Rinse it with water and mop to clean up any residue.
Apply the Primer
Concrete self-leveling requires a primer in order to fully adhere to the surface. Look for latex concrete bonding primer. Roll or paint the primer onto the concrete. Make sure that every inch, including the corners, is covered in primer. Any spots that are missed will cause the leveler to not adhere, which will result in cracking and pitting.
Prepare the Surface
Use a level to go over the slab and identify the low areas. Mark these with a pencil. Follow the manufacturer’s directions to mix the compound with water and aggregate, if needed, in a clean bucket. A power drill with a mixing hook will speed up this process. The leveler should have a soupy consistency.
Apply the Leveler
Pour the leveler onto the area. Use a trowel to spread the leveler around the space and feather it onto the edges of the area that you are working with to create a natural transition. Keep in mind that you only have 10 minutes or so to work with the leveler, so work fast. Once you have smoothed the leveler across the space, allow it to dry.
