Ceramic tile install in a concrete basement
The concrete slab was done 2 years ago and is fair stable, though some hairline cracks have formed.
What's a reasonable process to use?
I'm thinking Delta FL (my Home Depot doesn't seem to sell Ditra by the foot any more) mortared direct to the slab, then tile on top of the Delta.
Based on previous threads I was going to use the modified thinset below the Ditra and then unmodified on top.
Near one corner of the basement the slab does seem to be sloping downward. Will the Delta FL or Ditra help with that or is there something else I should be doing?
