Concrete in my driveway is chipping (chemicals used for icy roads is my understanding). Anyone have any ideas on how to repair? Someone told me that resurfacing was not a good idea, but I'm not sure what else could be done outside of replacement. I don't have a lot of spots so I was thinking of pressure washing the whole driveway and spot filling using a bonding agent and then sealing the entire driveway to help prevent future issues.

It would be nice to see a picture. Thin patches of concrete are a waste of time and money. Thin concrete patches crack and come loose. Concrete shrinks as it cures. From the sound of your description, it sounds as if an epoxy type product would be the best remedy. Yes, you need to clean the surface well in which the product will be applied. A liquid sealant when finished will diminish the difference in color (from the patches) and will provide an overall resistance to water penetration. You can purchase those products at your local hardware store.

Never use salt on your concrete driveways and sidewalks at your residence (unless you own a business and are concerned with litigation from someone falling).

I don't use anything on my concrete for salt...this was from the roads and what the State put down...it's pretty much right in the area I park my vehicle. I'll look up some epoxy material...doesn't matter too me too much if there is a color difference I just don't want it to continue.

Another option is to cut out some of the chipped area, then use concrete to fill in the sections you removed. You can do that with a circular saw using a diamond cutting blade or an abrasive blade. If you opt to use an abrasive blade and you have a few place to repair, get a few abrasive blades. Those don't last too long when cutting concrete. Ideally, you make the cuts on an angle too, and do that in such a way that the top of the hole you make is smaller than the area below it - you're going to have to break up the pieces to remove them anyway. If you do that, the patch locks in a lot better.

I should note that I've done this on concrete walkways, but I've never done it on a driveway. It would hold up better than a skim coat to hide the pock marks, but I'm not sure how well it will hold up to a couple of tons rolling across it.

country is on the right track. If it's a driveway, and scattered throughout, then look into the use of an epoxy to give you a finished look.

If the damage is done at the end of the driveway you could cut out the end, and repave it.

Salt is not as bad as some of the chemical de-icers. They will definitely tear up concrete, especially new concrete. We tell people not to treat that first Winter if at all possible.
