[ERA 778]

I acid washed and epoxied my concrete floor a few years ago. Since the garage was already at least ten years old, I was concerned about how well the epoxy would hold up, so I cleaned the greasy areas multiple times. Despite all this preparation work the epoxy still came up in some areas. I also had problems where it appears that the epoxy was pulled up onto tires - probably when hot tires driven onto the surface and cooled there. Overall, disappointed by the stuff coming up so easily in the oily spots. Repeated the process two years later with the same results.

I recall reading somewhere that part of the problem could be a lack of a vapor barrier under the concrete. Since probably no one puts a vapor barrier under a garage floor, this could happen to any installation.

I still like the overall looks of the floor and prefer it to the plain dirty concrete, but wish it held up better.

I think the whole process took about three days: one to clean, one to paint, and one to cure. One challenge is what to do with all of your "stuff" that goes in your garage.
