How to repair cracks in concrete with a concrete patch:

1. Chisel out the crack to create a backward-angled cut, using a cold chisel and a hammer.

2. Clean loose material from the crack using a wire brush, or a portable drill with a wire wheel attachment.

3. Apply at thin layer of bonding adhesive to the entire repair area using a paint brush. The bonding adhesive helps keep the repair material from loosening or popping out of the crack.

4. Mix vinyl reinforced patching compound, and trowel it into the crack. "Feather" the repair with a trowel, so it is even with the surrounding surface.
