Repairing Cracks in a Concrete Floor

How to fix surface cracks with concrete filler

Is your garage floor decorated with cracks? Here's how to fill them:

Materials and Tools:

workshop vacuum
stiff-bristled brush
scraper
chisel
ball-peen hammer
broom
dustpan
trowel
towels
knee pads
gloves
safety goggles
concrete crack filler

Steps:

1. Use an awl and a chisel to remove any large pieces from cracks in the floor.

2. Sweep away fine particles with a wire brush.

3. Use a grease-cutting cleanser to remove any oil or other contaminants around the repair area that might prevent the concrete filler from setting up properly. Sweep up all the debris around the area, being sure not to sweep dust back into the cracks. Finish cleaning by vacuuming out the cracks with a workshop vacuum.

4. Cut the nozzle on the bottle of the concrete filler to the size of the cracks, and slowly fill the cracks. Give the filler a few minutes to settle, and top off areas if necessary.

5. Smooth out any excess with a trowel.

6. Allow the filler to cure overnight. Add more filler if necessary.
