  • I had no idea but became curious. It appears not to be easy. There are several links depending on if it is old or new paint, and several methods. Go to google.com and search remove dry paint from flagstone I've seen everything from sandblasting to soy gel to mineral spirits with a wire brush. I do not know why someone would paint flagstone, though I am aware that in acidic precipitation it does steadily dissolve.
  • If its small spots or similar, scrape it off pressure washer (unlikely, but might work) paint stripper sandblast it off If the stones are completely painted, sandblasting (or turn them over)
  • A number of variables come into play. What kind of paint? Oil and water based may act differently. What kind of stone? Limestone is soft compared with granite, for example. How much paint? You will treat spatters, a major spill or painted stone differently. (The bigger lesson here is that specific questions yield clear answers-but back to the problem at hand.) I shy away from chemicals, but you may carefully apply paint remover in the least possible amounts, scrape the loosened paint into a container, disposing of it properly and clean the area thoroughly. Consider sanding, either by hand for a small amount or with a power sander. These are the 2 options i would consider first, though there may be some other good answers too. Hope it works for you
  • If it is just a few spots, perhaps I'd try to soften it with an appropriate solvent, then use a pressure washer. If this is a complete paint job, then sandblasting may be the best solution, although you might try a paint stripper. Sandblasting might be necessary in any event, since flagstone is probably porous enough that some of the paint will remain behind on the surface. Sandblasting will strip off that top layer.
  • Pressure washer is what I would try
