One of the most disappointing discoveries for a do-it-yourself tile installer is to find a crack in your ceramic tile floors. Knowing how to lay ceramic tiles and understanding the reasons why cracks may arise, will allow you to apply the adage “prevention is better than a cure.” Here are a few common reasons for cracking.
Tile Cracks Due To The Subfloor
One reason is because of the subfloor beneath the tiles. If your subfloor is wood, you will first need to install a concrete board. Why? Wood moves or flexes when you walk on it. However, tiles do not move. Without the concrete board to give support, the tiles will start to crack and break as the floor beneath it gives way. Some installers skip this step, but it will cost you more in the long run. This is because you may have to remedy the problem by taking up the entire ceramic tile floors. Then you will need to re-install the tiles on top of a concrete board.
Cracked Tiles Because Of Reflective Cracking
A second reason is because the ceramic tiles were placed on top of a concrete slab that was not given enough time to cure properly before the tiles were installed. If this is the case, the concrete could develop hairline cracks in it. This in turn will most likely cause the tiles to crack. Tilers called this “reflective cracking”.
Tile Cracking Due To Gaps in the Adhesive
A third reason that tiles can crack is because the tiler did not take enough care to ensure there were no gaps in the adhesive beneath the tile. Adhesives go hard after they cure. Therefore if there is a gap in the adhesive and someone steps on the part without the adhesive support, the tile can break. It is essential that the tiler spreads the adhesive uniformly beneath the ceramic tiles. The only way to know if this is the case is to pry up the tile and take a look at the adhesive.
