I just poured the floor in my barn a month ago or so. When they cut it he snapped some lines and sprayed a light coat of clear poly over it so the water would wash it away when cutting. Well, now I'm ready to put a clear sealer on the floor and can see a line of poly down every cut. Any suggestions on how to get it off without etching the concrete? I've tried paint/lacquer thinner, brake cleaner, myratic acid and a few other things without much success. A pressure washer didn't do a thing. The acid left a noticeable etch where I tried it. The brake cleaner actually worked the best but took a lot and I scrubbed a lot. Any ideas on what else I can try??
