There are bonding agents that you add to the patching compound, and there are bonding agents that you paint onto the old concrete. You can actually use both, if you wish. These compounds work very well if you follow instructions to the letter. Some of the bonding agents you paint on the old concrete must cure slightly before you add the patching compound. They are usually a milky white color when you paint them on. Depending upon the temperature, wind, and humidity, they then become clear. When the agent turns clear you can then add the patching compound. Pin the Patch. Large concrete patches such as a step, corner of a driveway, sidewalk, or patio must be attached to the old concrete with a mechanical pin. The cement glue or additives will not do the job on their own. Ive successfully employed standard reinforcing steel bars for years. Theyre inexpensive, easily obtainable, and the new concrete readily grabs onto the bumps and knobs on the reinforcing steel. The rough profile of the bar also is an advantage when you drive it into the old concrete. As long as you drill the right sized hole for the rod it is virtually impossible to remove the rod. In fact, as you drive the rod into the old concrete it will feel tighter than when you drive a nail into wood. Smaller galvanized nails can be used for pins as well for small repairs. Just size the pin for the amount of concrete youre installing. You want at least an inch of concrete to surround a pin. Concrete Pins VIDEOWatch this video below please to see what Im talking about with respect to pins to hold one concrete patch to another. This video is number five of a seven part series about putting in a trench drain. In the video I wanted to show a homeowner how to deal with a situation where they ran out of concrete and how to hold the old to the new.

Pay attention in the video how the pins are at opposing angles so they act like anchors once the new concrete hardens around them. Installing the Pins.

Try to stay away from the edges of the old concrete. You want to drill directly into the center of the old concrete. Use a four pound, or heavier, hammer to drive the steel pin. The length of the pin should be predetermined. In other words, dont cut off the steel after it has been driven into the old concrete. Always try to maintain a 1 inch or better coverage of patching material over the pin. If you have the time, I would also recommend that you paint the pin with a good metal primer. Rebars can and will rust within your concrete patch. If it gets bad enough, the rusting pin will expand and actually crack the patch The extra time spent painting the steel pins is worth it.
