How to Patch Concrete Floors

Concrete is a commonly used material for flooring. Whether you plan to leave your concrete floors exposed or cover them with a material such as hardwood or tile, it is important that they are smooth and even. Fortunately, patching a concrete floor is relatively easy and requires only basic tools. This is a project that the average homeowner can complete in a weekend.

Things You'll Need

• Chisel
• Hammer
• Wire brush
• Water
• Bucket
• Concrete mix
• Trowel
• Caulk gun
• Tube of latex concrete caulk

Instructions

1. Use your chisel and hammer to chip away any loose concrete or gravel. Remove and dispose of the chipped away concrete.

2. Sweep the holes with a wire brush to remove any debris or dust. This will give the patching compound a solid surface to adhere to and will provide better results.

3. Blend concrete mix and water in a bucket. This can be done with a simple stirring stick. Slowly add water until the mixture resembles a thick paste, like peanut butter.

4. Apply a 1/4" layer of concrete to each hole using your trowel. Allow one hour for this layer to dry, then repeat the process until the holes are level with the rest of the surface.

5. Use your caulk gun to shoot latex concrete caulk into any remaining cracks. Fill each crack completely, then wipe away any excess caulk using your trowel.

Tips & Warnings

• Wear safety goggles when chipping away concrete to avoid injury to the eyes.

• Do not add too much water to your concrete mixture, or the patched areas could crack as they dry.
