I have recently removed 2-inch ceramic tiles from our entry (with hammer and chisel). Left behind is the webbing (mastik?) that held the tiles together when they were originally laid down and the old thinset mortar. I am having a very difficult time getting it up off of our concrete floor underneath. A hammer and chisel is only semi-effective. One reference book I have shows using a long handled floor scraper, but I don't think this will get it up (it's really stuck on there). There must be a quicker and more effective way to do this. Should I consider a floor sander? Is there a chemical that would work (and not damage the concrete)?
