How to Fix Unlevel Concrete
- 1). Remove all objects from the surface of the concrete floor.
- 2). Sweep or vacuum up all dirt and debris from the floor.
- 3). Pour the degreaser onto the concrete floor and allow it to settle for 15 minutes.
- 4). Scrub the floor vigorously with a stiff, plastic-bristled brush to remove any oil stains and marks from the surface.
- 5). Rinse the floor with a garden hose and allow the surface to dry completely before continuing the project.
- 6). Pour the latex primer into a paint tray and apply a single, even coat of the primer onto the concrete surface with a paint roller. Allow the primer to dry overnight.
- 7). Identify the low spots in the surface. It is important that you locate the unlevel spots first before applying the compound so that you can work quickly on those spots.
- 8). Mix the self-leveling compound and cold tap water quickly in the plastic bucket with a trowel. Read the side of the compound package for the proper ratio of water and the desired consistency.
- 9). Pour the compound into the low spots on the concrete floor and gently smooth over with a trowel. Work quickly, because the compound will fully cure within 30 minutes of application. You can apply your flooring material to the concrete 24 hours after application of the compound.
