How to Fill Large Concrete Cracks?

Large concrete cracks can be an unsightly and potentially dangerous problem if they are not addressed promptly and correctly. Fortunately, it is not too difficult to fill large concrete cracks in a relatively short amount of time. Here are some tips on how to fill large concrete cracks.

First, make sure the area is clean, dry and free of any debris. A wire brush works great for this. If the crack is deep, use a vacuum cleaner to suction out any loose material.

Next, fill the crack with a concrete patching compound. Make sure it is designed specifically for filling large concrete cracks. Follow the manufacturer’s instructions for mixing, application and drying.

Once the patching compound has dried, use a trowel to smooth out the surface. If necessary, use a putty knife to level out the patch.

For an extra layer of protection, use a concrete sealer. This will fill in any remaining cracks, and protect the surface from moisture, dirt, and other elements.

Finally, if the crack is too large or deep to be filled with a patching compound, you may need to use a concrete crack filler. These are available in liquid form and are easy to apply. Simply pour
