My dad layed tiles in his kitchen recently. He had some plywood type stuff that he layed them on top of so they are on a flat, even surface. But then someone told him he should have put a netting type stuff underneith the tiles too, to keep them from breaking. Is that very important, will his floor be ruined now?
Its called wire mesh. Its not used as much anymore. What makes tiles or grout crack is the wood below the tiles. If the floor joists are too far apart and the plywood is not thick enough it can cause the floor to move. Even a little bit of movement can cause the tiles and the grout to crack. The wire mesh will not help if the floor moves.
