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. Fill any low spots with a cementitious leveling compound following the manufacturer s directions and allow it to dry before proceeding. It spreads across uneven slabs filling in low spots as it creates a new level surface. High spots may require grinding the concrete to achieve a level surface.

Before you pour give the existing slab a thorough cleaning with a degreaser to remove any contaminants that might interfere with achieving a strong bond. Check your wood flooring manufacturer s recommendations and sand any high spots with a concrete grinder. 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.
