How do you prepare the surface of ceramic tiles for a floor levelling compound?

Answer:
Glazed? They must be ground to etch the glaze. There ought to be a floor sander available to do that.

Floor tiles usually lift easily with a shovel once the first 4-5-6 or so are up, and that would make for a far better job. If the rest won't come up easily after you have removed the first few, you can then decide if you just refill the small hole you've made before levelling it all, over the tiles.
