Concrete is a highly durable material, making it a great option for things like patios, floors, and sub-floors. Concrete isn't indestructible, however, and over time can crack, crumble, and even sink if not installed properly. The good news about concrete is that it can be resurfaced, repaired, and leveled out if need be. See below for instructions on how to level out a concrete floor.
Prep Your Floors
Begin by removing everything from the area including baseboards, furniture, and any flooring currently on your concrete sub floor.
