Has anyone had to deal with pitted concrete due to the salt in the winter time before you put down your floor?

Yea. Where there is snow and ice there is "pitted" concrete. The only defense is a strong, dense, air entrained surface or a sealer like salt guard. Also difficult to repair. As long as the salt doesn't get at steel reinforcing, it's mostly cosmetic.
I have a couple bad sections on the house. Was thinking of repairing them, but they are beyond "pitting".
How about self leveling epoxy? I thought about that but my problem areas are outside and the epoxy would probably yellow or discolor. Personally I'd rather have a smooth surface. Maybe the epoxy experts can weigh in here.

I definatley would concider epoxy. Does anyone think the epoxy would fill the pitting? Its not too bad yet.

Epoxy won't match the surrounding concrete. I'd try a cementious product like Ardex CD. It will go feather out pretty well and come close to a color match.

Thanks, would it be possible to put down a colored epoxy finish over everything without worring about the Ardex popping up? Or would the epoxy level itself out?

I'm not an expert on epoxy but the Ardex is pretty tough. We have used the it on exposed exterior surfaces that get a lot wear and it holds up well. I think it would be fine but maybe one of epoxy floor guys will weigh in.

I had a lot of issues with my concrete http://garagejournal.com/forum/showthread.php?t=104501
and after considering all that was involved to repair, level and smooth the surface in prep for an epoxy coating, I went with Race Deck. There are other non-epoxy products out there that are worth considering as the prep is very easy and the impact on you is minimal ( i.e. leaving all garage contents outside for days until floor dries) so the average Joe can have it all done in one day. Food for thought.

Prior to coating your floor, either coat these areas with 100% solids epoxy, may need (2) coats or you can try our concrete repair material.
Our concrete repair material consists of resin and aggregate. In this case I would not use all the aggregate included, make a slurry and squeegee over the pitted areas.
Sand smooth, once dry.
Epoxy based repair materials will far outlast cement based products at these ultra thin thicknesses.
This repair can be made (2) days ahead of the coating.
