Garage floor paint

I am pretty sure you have to wash the floor down with some kind of acid wash stuff. They did that to the shop I work in when we put on an addition. They washed it down with something and then painted it after it dried. Still peeled up in a few spots though. I think they used some epoxy type concrete floor paint

YOU MIGHT HAVE TO SCARIFY THE CONCRETE FIRST,(BREAK UP THE SURFACE OF CONCRETE WITH A MACHINE,YOU COULD PROBABLY RENT ONE)
I HOPE THIS HELPS

Paul is right on the money.. the concrete must be etched with an acid wash for the paint to stick...
