Len, If you haven't started the removal process yet, here's some advice. Put the remover on in *very* small areas (like 3 sq ft) at a time. Then when you have scraped off all the adhesive, wash the area & let it dry before you move on to another. I spent 16 hours this weekend removing a toxic waste dump of my own creation in a back bedroom. I finally got so disgusted by the muck that I used nail polish remover (with acetone) and artificial steel wool to scrub at the floor. Wear a respirator - I bought the most expensive one 3M makes & I couldn't smell a thing until I took it off. Then I ended up turning fans on all over my house (the product was supposed to be odorless). I am now considering using MEK to finish off either the floor or me. I am glad that this is the only room that had old vinyl under the carpet. If I could have put down sheet vinyl in the room, I would have. Also I used TSP to wash the floor afterwards & it seems to cut through the muck somewhat.
