We built a room and applied 2 coats of Ace Primer Sealer to the clean sheetrock. Giving sufficient drying time between coats. Days later then applying ceiling paint and days after that applied two coats of paint to the accent wall (1). When removing the painter's tape after the second coat, the ACE Primer/Sealer lifted right off the sheetrock like a snake skin taking and leaving the sheetrock intact with a nappy felt like feel. The paper was still left on the sheetrock, but it had roughed it up enough that the wall would have to be mudded over to have a smooth finish. After showing it to my contractor, the store personnel and supplying samples of the skin from the 8 ft stips. I was told to demo the walls and rebuild. They are still trying to get out of admitting the bad primer, but these were new walls and were treated as such, cleaned before painting. The primer had a weird feel to it, as mentioned by all who saw it. It even removed itself from the ceiling taking the ceiling paint as well. Needless to say, I didn't want to waste any more paint by applying it to my other 3 walls. We demo'ed the whole room of the bad primer/sealer walls and rebuilt. We are back to the primer phase again, and I can tell you that I will not be using any ACE paint on this new construction! When their reps tell you to go ahead and make the fix, then to have corporate do all that they can to try to get out of the responsibility, their integrity is lost in my eyes. I've had to pay to build this room twice to date because of ACE primer sealer. I don't care if their paint was free, it would never end up on any of the walls I'll paint for the rest of my life. I've heard good things of Sherwin Williams paint and will try theirs.
