Two Questions Joe Sykes 02 Mar 2017 13:43 EST

My son just had a request to remove polyurethane from a slate floor (which he estimates has been on for more than 30 yrs.) which is starting to peel. Any suggestions as best method for removal?  Also would like any feedback regarding working with high end home property managers? Good/bad experience? What to expect, do/not to do? Thanks for any feedback.
