We are spending Christmas week installing ceramic time over very stuck down vinyl asbestos tile. The only problem is that in a couple of places like the entry way and the kitchen there is vinyl sheet flooring that seems to be bonded to the old vinyl asbestos tile. We got the carpet, pad , tack strip and molding out without any problem, but this vinyl sheet flooring is driving us nuts. I bought a scraper that isn't doing the job. Tried the hair dryer and that won't cut it. Help!!!
