It will say right on the bag what size notched trowel to use for a
particular size tile. That will determine the amount of thinset
that's applied. You can go thicker, or a little bit thinner. You
could thinset some 1/4" backerboard to the slab, then thinset on top
to set the tile, but a 1/2" bed isn't too extreme so you can go either
way.
