I'm in the process of installing tile over most of the downstairs
floors of my house. In the kitchen, with a plywood subfloor, I have
installed the 13" X 13" tiles over 1/4" Hardibacker.

I did a poor job installing one of the tiles (ended up with a corner
kicker) and had to remove it. In the removal process some of the
Hardibacker delaminated and came up with the tile. As a result, the
Hardibacker in part of the area (about half) where the replacement tile
will go is between 1/16" to 1/8" lower than it should be, as a result
of the delamination and pull-out.

Any advice on leveling the Hardibacker prior to installing the
replacement tile? Just set it in a thicker than normal layer of
thinset? Level with concrete patcher prior to installation? Cut out
the square of Hardibacker and screw down a replacement piece? Other?

I would just use a little extra thinset.
