I'm in the process of redoing the floor in our guest bath and I'm ripping up the old floor tile. Thing is that I'm left with a bunch of thin-set on the hardiboard that the previous owner used. Can I simply use self leveling concrete/cement to fill all the voids and get me back to a flat surface, rather than having to remove all the old thin-set - a painful and almost impossible job. The hardiboard has also been laid down with thin-set, so it's a real pain to remove back to the subfloor.
I'm thinking a 1/4 inch or so layer of self leveling concrete will get me back to a level sound surface and all I'll need to do is somehow block off the air register and the toilet drain so they don't "fill" with the leveling cement. I also plan to hold back the cement from the tub sides so that as it dries it won't crack my tub - is this necessary?
Any help/advice would be greatly appreciated.
