I'm installing a new ceramic floor, and I have to remove an old one that was done very poorly and WITHOUT a subfloor (on the builder's original floorboards).
Do I need to worry about removing all the grout in all areas of the existing floor, or is there some room for leftover grout, so long as I remove all the tile material?
The height differences before installation of the new subfloor would be at most one-eighth of an inch, and I'll be laying an additional one-half to three-quarter inch plywood before tiling. The existing floor is three-quarter inch particle board.
Any suggestinons would be helpful and appreciated. Thanks, Stacey.
