The installer on one of my shower jobs ran into something he had never seen before, and neither had I. While trying to cut the tile it would break or snap wrong. He tried a hand grinder, and wet saw, and score and snap. All methods would not produce a cut he was use to. If cutting on the wet saw, it would cut fine, and then about half way through it would break the rest of the way. The score and snap method, it would veer off at the end at a strange angle. The hand grinder it would do the same thing as the wet saw, it would just snap. He made some adjustments to his wet saw, and would cut both ends before going all the way to the middle, and he was able to make it work. Until he got to the mixing valve and body sprays, where holes were needed in the middle of the tile. Using the grinder, I watched as he began to make a cut in the middle of the tile, he was 2/3 through the thickness of the tile, and the whole tile popped. He went through 6 tiles, until he finally had a tile that did not break. He sat it down on a stack of tile in the box, while he spread his thinset. While it was sitting on the boxes, it too snapped. He is so frustrated. He had some success with flat troweling thinset on the back of the tile the night before, and then cutting the hole the next day, but it does not always work. The tile is a 12x24 Florim Tile. Anyone ever dealt with this kind of issue?
