The new tile floor in my kitchen with 14 inch tiles are clicking. We pulled
up a few and reset with more mortar but more are clicking and I think a few
of the originals.

I am afraid the subfloor (two 5/8" plywood sheets) moves too much. It has
been suggested that I pull up the bad tiles and then screw the floor to the
joists. Will this be sufficient? The floor does seem to move when my 250
lbs walks on it - the movement can not be seen from the basement - it is not
the joists. Would additional cross bracing installed from below help?
Would additional wood from below then screw up and pull down work (plywood
does not hold screws well. I do have full access from below.


I think you have hit on the best solution. Pull up the tiles and
screw the boards down every 10 inches to the joists. No cross bracing
is necessary.

Then smear on lots of the most 'expensive' tile mortar you can find.
The expensive stuff doesn't dry out like the cheap stuff.

That should hold it in place for 20 or 30 years.
