What are the causes of cracks in tiles?

The quality of tiles is good or bad. If you choose those unknown and insecure tiles, it is likely to be inferior products. When in use, they are overloaded and have insufficient hardness, so they are easy to crack.

Tiles don't soak in water. Before the tiles are laid, the water-absorbent tiles will be laid first without soaking in water. After paving, it will absorb the water in cement mortar, resulting in a large amount of water loss in cement, hollowing, falling off and cracking of tiles.

Unqualified adhesive: Unqualified adhesive will also cause problems such as cracking and falling off of tiles. The ratio of bonded cement mortar is usually 1: 1. If the proportion is not harmonious, the bonding effect will not be achieved.

When laying ceramic tiles, there is no porcelain joint, and the extrusion caused by thermal expansion and cold contraction is easy to crack, empty drum or fall off the tiles. Tiles or caulking agents have the phenomenon of thermal expansion and cold contraction, so tiles should leave gaps.

Wall deformation is also easy to cause vertical, horizontal or oblique cracks in tiles. Therefore, before paving, it is necessary to ask the staff to test the wall first to see if the wall installation is firm.
