@nprofile1q...My kitchen had cheap vinyl tiles badly stuck on top of an older lino/vinyl floor. The vinyl tiles were both horrible and very damaged. Unfortunately the lino under was also damaged quite badly partly from the glue used for the vinyl tiles.
One day I got annoyed with it and just ripped it all up, and underneath were the original (probably, 1920s) dark floortiles, the type that contain asbestos but which are fine as long as you don't go breaking them apart. They look *so much* better!
