I have been reading online about the recomendations for ceramic on resilient floor tile. In our case, the house is old enough for asbestos to have been used. (unknown)We have a slab with 12 x 12 glued down tile. (very flat and mostly very tightly bonded) carpet was removed from atop the tile revealing the old layer of glue.
Can we use a concrete board on top, or shoule we reconsider going with ceramic at all? ( we already have the tile but can return if nec)
