I have small cracks on my concrete patio wall, I want to know what is the best material for repairing exterior concrete cracks?

I've used Quikrete's product for years and am very happy with it. You can get it at Lowe's, Home Depot, etc.

Here is the product:
QUIKRETE® - Concrete Repair

Thanks Rick, Your Experience speaks for itself...

All concrete will crack eventually. Once your wall gets a crack no patch will ever hold as well as the original wall. So I am thinking you want to make it just look better, right? Roughly how large is the crack, can you stick a matchbook cover into the crack or your whole finger?

Hi, Thanks for your response, the cracks are small, a little wider then a matchbook cover but not as wide as my finger and they are long, any suggestions?

I apologize to Rickj for not opening his link. QUIKRETE® - Concrete Repair Appears we both think this product is about the best. Sorry Rick.
