I had sheet vinyl flooring glued to my slab floor. I was told I could
use thinset to lay ceramic tile directly on the clean vinyl. I didn't
believe it so I tried a few pieces inside a pantry closet. It stuck
so well that I did the whole kitchen. Six years later absolutely no
problems.

I am putting up my condo for sale and want to spruce up the small

The floor now has peel and stick vinyl (12 inch) tile that seems well
stuck even though it is quite scuffed up. Several people have told me
that I can lay ceramic tile right over the vinyl.

Has anyone done this? Did it work out?

From a bit of searching I have found a few web sites that suggest

sanding the old tiles to roughen them up, and also to screw on the
vinyl tiles before laying the ceramic ones.

What do you think? I don't want to spend a lot of time and money on
this, but at the same time I don't want it to look like crap....

Thanks!
