I am remodeling a half bath and have a problem that the floor has a hump in it. The room is 63" x 72" with the high spot near the center and a 1/8 to 1/4 inch drop nearly all the way around the walls. I have sanded the hump down to this level (it was higher) and do not want to thin the plywood more. I have read the threads on self leveling compounds and durarock like applications but my question is can you use durarock over the self leveling compound. When I drive the screws through the durarock through the compound into the subfloor will it mushroom the compound underneath such that you have stress concentrations and thus cracks in the future. I want to put tile over this. Any help or suggestions would be welcome.
