- 1). Chisel away the brittle or pitted sections of the concrete using a standard hammer and chisel. Fashion the section into a square with an even bottom and slightly undercut sides.
- 2). Remove the concrete pieces from the hole. Sweep away concrete dust or use a shop vac to vacuum up the debris.
- 3). Apply a concrete bonding liquid to the sides of the square hole using a paintbrush.
- 4). Mix the cement and water. In a large bucket, mix the dry cement with water in the ratio provided with the cement mix packaging.
- 5). Scoop up the concrete with a trowel and fill the hole.
- 6). Work the concrete evenly into the corners of the hole and then smooth the concrete with the trowel so that it is even with the existing surface.
- 7). Apply a texture to the still-wet concrete by lightly sweeping a broom over the surface.
- 8). Let the concrete patch dry for 24 hours before using the concrete pad.
