Question ceramic tile experts

[RenoF250]

If only part of the tiles are loose and it is tiles from a specific company I would be concerned that there is something preventing adhesion such as oil on the back. I would clean them very well before resetting and check the the others closely so you are not doing them in 6 months.

How did they turn out?

2 bad italians, 4 bad mexicans (country of origin for tiles)
the tile all had great coverage... but the mortar seemed dry as if the slab had sucked the water out to fast when i set them last year. MAF i had to use the air chisel to break out all the mortar off the slab before i put em back in.
i over buttered em this time with a slighty wet mortar, going to grout tomorrow night.

best thing is i didnt break em
