how does one tear up ceramic tile without damaging the adjacent tiles? When my house was built, the tile people talked us into this "new way" of putting down tile "to make the floor stronger" so the one foot tiles wouldn't crack over time. Well the new way actually worsened it, we are now six years out and so I think the problem has hit it's end and is no longer progressing. Joists are sistered 2x12's 16 inches on center, then subflooring is yellow pine planks, then a layer of thinset, then 3/4 inch plywood boxscrewed every 6 inches to the planks prior to the thinset setting, then another layer of thinset, (supposedly after everything was dry, but I question that part about letting the bottom layer dry first) then the tile, one foot square ceramic. What ultimately happened was having the plywood between tow layers of thinset, the plywood swelled at the joints and so, not at every junction line, but following the long joint of some of them there is a long crack through the tile, in some places 13 feet long, (the kitchen and dining area is one big tiled room). I was considering pulling up the affected tiles and then a few extras in a perpendicular fashion and replacing the white marble like tile with some lines of black marblelike ceramic tile (with would match our black marblelike formica counters) and maybe some burgundy colored ones for a splash of color, so it would look like an inlaid tile pattern and not a retro-repair job. I was also considering, maybe even using a pattern of smaller tiles so that if the crack reappears it should hopefully happen in the grout line and not through the tile. Any suggestions?
