With one day of installation work completed I checked the layout and realized it would result in sliver cuts along some of the main walls. This morning I stopped them from continuing work and their supervisor agreed to have them redo the installation. They are removing the tile cleaning off the thin set and plan to reuse as much as possible. The 12x24" tile is not grouted. Is it acceptable to reuse the porcelain tile after its been installed? Will there be unseen defects in the tile?
