Can anyone recommend a good concrete sealer that will protect from automotive oil drippings soaking into and staining the concrete? If I'm going to do it, I would just as soon do it after it cures, and before I start using it. That way I can eliminate the cleaning, pressure washing, etc.

I know it is more than a sealer, but when we visit Arizona I see a lot of driveways with the epoxy coating that we use inside.  I don't know how it stands up to UV, but it stands up well against oils, fuels, chemicals, and even tire wear.

If that's what I think it is it's supposed to stand up to urine on barn floors. I didn't know anyone used it on concrete outdoors. I learn a lot interesting little tidbits on here.

they make if stabilised products, but once again with out a moisture barrier  it will not hold up.  Not too mention the concrete  used for that environment  is much better then used on a drive way.

The problem with the Epoxy Coatings is the cost. My neighbor just had the inside of his garage done, and it looks beautiful. But all total it cost him over $3.80 @ sq. ft. installed. You can find a closeout on ceramic tile for almost as much.

A lot of homes in Sun City do the Epoxy Coating on the entire driveway. It looks great, and wears well. Again, the problem is cost. They make clear, high gloss sealers that look almost as good, but are far cheaper and easier to apply.

I don't know what barns you have built, but it is no different in our region.  Shop floors, barn floors, garage floors, and driveways ... All the same mix.

They are using it on garage floors nationwide, and most have no vapor barriers.  Our local Ambulance garage has it, and it was applied in the mid 80's..
