I've had personal experience with Self Leveling cement.

The first time we put it down, we were given the wrong bonding glue (yes there's glue involved) and it didn't adhere.

We got this super strength glue to go with it after we took it out and put the stuff in, and it works great.

I would recommend the stuff, but make sure when you get the stuff get the strongest bonding glue that you can possibly get (There's a specific place that I have to look up to get it which I'll get for you later)
