Level Concrete Slab Before Flooring

If you plan on leveling a concrete floor you can do so with relative ease by using a leveling compound.

Level concrete slab before flooring.

To level concrete floors start by cleaning the floor and filling in any cracks or holes with concrete filler and sealer. It spreads across uneven slabs filling in low spots as it creates a new level surface. To resurface an uneven concrete slab begin by laying a long straight 2x4 wooden rail across the concrete slab floor with one end positioned on the high point in the room. Check your wood flooring manufacturer s recommendations and sand any high spots with a concrete grinder.

Fill any low spots with a cementitious leveling compound following the manufacturer s directions and allow it to dry before proceeding. When you re finished spread some concrete leveler primer over the floor and let it dry until it has a tacky finish. Level the concrete slab by using a long rigid straightedge to locate high and low spots in the surface of the concrete pad. Then go over any particularly high spots with a concrete grinder so they re level with the rest of the floor.
