re: Stained Concrete Floors recommendations

I did mine originally and watched the guys and gave details and told everyone, and put paper down and the subs still messed the concrete up. I wish I would have polished them a bit before, but mine came out great and would do it again. In an existing home, I would rent the grinder from HD and do it while the walls are out. Then stain, put down paper(they make a heavy duty CB now), then let the subs finish. The grinding will help. I upped my PSI and have Post-Tension, so no cracks. If there was glue on the floor, it would need to be ground anyway.
