I have a walk in closet that has a ceramic floor. Of course my wife wanted me to change it so off I went to Home Depot and got a chisel and a large hammer and got it all up. Now I have a very uneven floor that is basically rough from the thin set from when the old tile was installed. Can I level the floor out and then tile over the leveling material or should I scrape all of the old thinset off? Getting the tile up was a chore, But the old thinset is next to impossible. Basically I have a closet with a rough thinset coated floor. She is about to kill me!! Can tile be put over the old rough thinset surface? Would I be better off to use some kind of leveling material then just capet over it? I believe she has her heart set on tile, But I am not sure I can get the thinset up.
