I have an indoor concrete slab surface in a "mud room" between the house & garage, which was painted white by my father years ago. I have no idea what kind of paint he used. Paint almost immediately began to blister in places, is pretty much totally gone in the cross-room traffic path, and is patchy elsewhere. Trouble is, SOME of the paint seems to adhere well, while the spot right next to it can be scratched up easily (I was hoping the whole mess would come up easily with a 4" razor scraper, no such luck). I'd like to remove all of it to have a good surface to either paint or glue down a vinyl floor. What would be ideal would be if there were a relatively safe stripper I could apply to the floor then suck the whole mess up with my shop vac, but I'm guessing that would be too easy to be true. Any idea on the best way to deal with this mess? It really looks like hell now, & I'm afraid it's not stable enough for another covering to remain down in the long run. I'd REALLY like to repaint it if possible.
TIA
