Alright, I'm new to tiling and I have this second story condo that has a
conrete floor (at least it looks that way). What I'm

wanting to know is, should I lay backerboard over the concrete? Isn't the
concrete stable enough for ceramic tiles? I know

that there will be cracks that need to be filled, and that I might have to
use a leveling compound. But all that sounds

better than buying and hauling hardibacker into the condo and drilling
holes into concrete slab. Any information would help
