Enlarge the hole with a chisel and hammer and break away all of the brittle concrete. Be sure to undercut the side of the hole to make it easier for the concrete mix to adhere to the wall.
Brush the loose bits of concrete out of the hole with a wire brush.
Brush on a concrete bonding liquid with a standard paintbrush. Be sure to cover the sides and bottom of the hole with the liquid.
Mix the concrete. Mix the dry concrete with water according to the instructions provided on the concrete mix packaging. Use a shovel and mix in a large bucket.
Use a pointing trowel to press the concrete into the hole in the wall.
Spread the concrete evenly over the hole so that it is level with the surface of the existing wall.
Sweep a moist broom over the patch to provide texture. The patch should dry within 24 hours of application.
