Help is needed please! We want to remove some nasty looking melamine floor tiles in the hallway of our edwardian semi. We know there is an original tiled floor under there, the problem we have is how to get the melamine tiles up. They were stuck down with what looks like a black sticky adhesive (bitumen?), and are stuck fast. I have also heard that some 60's melamine tiles contain asbestos - any truth in this?. Thanks, JAMES
