Hello, I am one of the resident tile pros on this site. Here is a question to other installers. There seems to be a lot of controversy over installing tile over vinyl or linoleum flooring. Some installers say absolutely not and that the tile may not stick well enough to the vinyl and the vinyl may not be stuck down well enough. Others say that it can be done, provided you use thinset with 100% latex admix and sand the floor. I have never installed over vinyl myself but often wondered if it would actually work well as a crack suppression treatment. What are your thoughts or experiences with installing over vinyl flooring?

Thanks Del. It is promising to hear that others have had success with tiling over vinyl. I have spent hours, ripping out old, well stuck and hardened vinyl floors, that perhaps could have been tiled over, even resorting to using a scraper attachment on my electric chisel. I haven't heard of substituting new, inexpensive vinyl for a tile underlayment, but if it saves money and works well, why not.
