We pulled up the carpet in a bedroom, planning to redo the floor with some very cheap (33c/sqft) stick on vinyl tiles. They aren't fantastic quality, but we did another bedroom with them, and were very happy with the results.
Under the carpet, we found tiles! They seem to be some kind of adhesive tile.. not sure if they're lino or vinyl? Concerned about asbestos?
The carpet underlay was very stuck, and has left black marks/stains on the floor. Can we restore the floor? Can we just stick the new vinyl tiles on top? How would we prep it to do so? Can we remove the tiles (without dying of asbestos-inhalation)?
