Well there's useless, overbroad and wrong info.

Thanks for your analysis.

Replacing the tiles is the BEST bet.

The OP asked for repair techniques. "Replace it" is not an answer to
that question.


We once moved into a house that had an almond-colored ceramic tile floor
in the kitchen that had several hairline cracks and numerous tiny chips
that revealed the color below the surface of the tile. The best solution
we found for the cracks was an almond-color elastomer-type caulk forced
into the crack, then quickly wiped off the surface of the tile. For all
the little dings, we used one or more applications of almond-colored
appliance touch-up enamel. These repairs were almost undetectable unless
you were very close to the floor. The repairs never needed to be re-done
in the seven years we lived there.
