Just an update – The Klean Strip Premium Stripper (more info from the manufacturer) really works well. So far it has succeeded in turning all the tile and adhesive underlayment into jelly. I’m almost done with the floor (after 6-7 cans you would hope so lol) but man this stuff works extremely well. It basically takes everything off of wood – paint, epoxy, polyurethane, etc. I think that I should be able to finish cleaning off the floor with 4 more cans and 2 more days. Then I can focus on getting the remaining drop ceiling out and starting to repair the spots in the floor that need it.
