Mainly because when decorating and laying tiles, the width between tiles is not large enough, which leads to the arch of tiles over time. So when we step on the tile, it will make a snapping sound.

1. When the tiles shrink when they are cold, the tiles will squeeze together. Over time, the tiles will break directly from the middle. Especially when someone keeps walking back and forth on the tile, the weight of the whole person will press on the tile, and the tile will make a snapping sound if it can't stand this weight.

2. Once the tiles at home are cracked or damaged, if the tiles are intact, you can gently knock this tile loose, then pry it up, knock off the cement on the back of the tile, then re-pave the cement mortar and stick it back in place.

3. If there are irreparable cracks in the tiles, you need to replace them with new ones. You can match this broken tile with a tile of the same color, otherwise the color difference is very large and ugly.

4. Gently put the tiles back in place. It should be noted that it is best not to let anyone walk on the newly pasted tiles for a few days, otherwise it will affect the fit between the tiles and the ground, and it will still make a snapping sound after a long time.
