question to other installers on the site

I've been mulling over some ideas that kicked off during the discussion on tile over vinyl installs, and I wanted to pose a question to the other installers here, or anyone who has experience with this type of thing.

Is it possible to use SLC as an underlayment over vinyl? I've never heard of this being done, but in my research I've found specs that say that it can be. here's one little blurb

Concrete Resurfacing Over Ceramic, Quarry, VCT Tiles and Sheet Vinyl With a Self Levelling Concrete

I know Ardex is now making what they refer to as a liquid cement board, and I'm assuming the cost is fairly prohibitive for residential remodel, I find the idea intriguing, especially when it comes to the ramifications it may have for DIYers and home improvement types.

I'm curious in the experience anyone has had with this, or any ANSI/TCNA standards anyone may know of that may relate to this.

When I see vinyl, my instinct is to always remove it, but thats just me. That being said, sometimes I'm a bit of a dinosauer as I do only what I know has worked for me in past experience. I use mostly TEC setting materials, grout, etc. Just the other day, I was on their website and saw something new so I had to investigate. Apparantly they have an slc that can be used over vinyl. I read a little about it.

Here is a link to it.

In the dropdown box on the page, open the document "PDS - Fiber-Reinforced Underlayment".

I personally have never installed slc over vinyl, and til now was unaware that it could be done.
