How to Repair Cracks in Concrete Floors
More in Remodeling
Highlights:
Step 1: Prepare the Area to be Repaired
Use an awl and a chisel to remove any large pieces from cracks in the floor (Image 2).
Sweep away fine particles using a wire brush (Image 2).
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 (Image 3).
Step 2:
Cut the nozzle on the bottle of the concrete filler to fit the cracks, then slowly fill the cracks (Image 1). Give the filler a few minutes to settle and top off areas if needed.
Smooth out any excess using a trowel (Image 2).
Allow the filler to cure overnight. Add more filler if necessary.
