You see, that's the thing... You need to grind that top finish coating of your concrete off for the best results. This will allow for the primer(which you should be using) to set into the concrete and will allow your epoxy to set strong. Acid etch is okay, but you won't get the best results with it.

Never just paint anything on to the top of your concrete. That's why all these kits don't work to begin with. Preparation, while a pain in the ass will make or break the longevity of your kit.
