I got some free polyurethane / alkyd based floor paint and painted my garage floor (used as a woodworking shop). I didn't pre-treat it in any way, just cleaned it. The workshop is relatively new (2014) and the floor was just screeded flat (really well done job though). From what I've come to understand you should grind the floor first, or acid etch it.
So big a miss is this on my part, is my floor going to peel off very easily, or is it mostly a looks question? I don't need a perfectly flat and shiny floor, just want a brighter color that is easier to sweep clean.
