Leveling Uneven Floors
Clean the entire floor and patch any holes. Nail a strip of wood across door openings to keep the patching material from pouring into the next room.
Mix a thin mixture of the leveling compound and brush it on the floor as a primer. New concrete normally requires one one coat of primer; older concrete may require two coats. Follow the directions on the bag for both mixing and priming. Let the primer dry as specified by the manufacturer; usually but 1 to maybe 2 hours.
Mix a thicker consistency of compound, following the proportion on the container. Start in a corner on the narrow end of the room, pour the mixture on the floor. Pour the second batch next to it along the narrow wall. Repeat along the entire wall, and then work our way back across the room, pouring a new row of compound next to the old. Let the compound flow to level itself.
