Cracks can happen on a concrete driveway for a variety of reasons including the slab does not have adequate expansion joints, the footing is not deep enough, the concrete was too watery or too dry when poured, the concrete slab is too thin, uneven settling, too much weight along with many other reasons. A crack on a concrete driveway ruins the look of not just the driveway, but the entire house because it looks to be in disrepair.

Apply another line of epoxy composite repair material on top of it.

Use the metal putty knife to feather the repair material out and away from it on both sides to make it even with the rest of the driveway surface.

Use a stiff bristle brush top dab at the composite material to make it rough or move the brush in circles to match the rest of the concrete driveway surface.
