In our daily home life, we always encounter some troubles, such as hollow tiles and cracked tiles. I believe you will often see cracked tiles when walking on the road. So,What causes ceramic tiles to crack? Are you thinking that the quality of the ceramic tiles is too poor or that the decorator's skills are not good enough? Let’s find out together!
We all know that different causes of ceramic tile cracking have different solutions, so let’s take a closer look at the causes of ceramic tile cracking! ! !
1. How to distinguish the causes of ceramic tile cracking
Remarks: To distinguish the causes of cracking of ceramic tiles, mainly look at the cracking area and crack characteristics of the ceramic tiles
1. Single wall, regular cracks
If there are regular horizontal, vertical or diagonal cracks in the ceramic tiles on a single wall, it can basically be judged to be caused by the wall.
2. Linear cracks
The cement coefficient is too high, and the expansion coefficients of cement mortar and ceramic tiles are inconsistent, causing the ceramic tiles to deform and crack. Such cracks are generally linear in shape and vary in length.
3. Cracks
If the ceramic tiles are cracked due to quality problems, most of them will show a crack shape like a turtle shell.
4. Multiple locations and irregular cracks
Generally speaking, it is impossible for the foundation of every wall in a house to have problems. The possibility that the compressive strength of the same batch of ceramic tiles differs too much is also relatively low. Therefore, if there are irregular cracks in some tiles on a small number of walls, it can basically be determined to be related to irregular construction.
2. The main reasons for cracking of ceramic tiles are these aspects
1. Poor pressure resistance of ceramic tiles
Cement mortar and tile adhesive will put a certain amount of pressure on the tiles during the drying process. If the tiles' pressure resistance coefficient fails, they may crack during this process.
2. The cement label is too high
The strength of the adhesive material is too high, which causes the tiles to break when the cement mortar shrinks and deforms.
3. There is a problem with the wall base
Cracked tiles tooThere may be a problem with the base of the wall itself. This situation is more obvious on bathroom walls coated with a waterproof layer. The waterproof layer of the wall and the plastering layer of the tiles are separated, the cement mortar shrinks, and the tiles will crack. This situation is not due to insufficient bonding strength of the cement mortar, but to the detachment of the entire base layer.
4. New wall deformation
Newly built walls are prone to deformation. Many owners use light steel keels to build partition walls in order to reduce load-bearing, which will make the deformation more severe, and the deformation of the wall will lead to rupture.
5. Ceramic tiles are located at the pipes
In general houses, the developer will reserve a smoke (gas) pipe for each house design, and this pipe is made of cement pressure plate. If bricks are laid directly on it, the cement pressure plate will shrink and add As pipes expand with heat and contract with cold, the tiles may crack or even fall off.
6. Insufficient soaking of glazed tiles
The soaking process may also be one of the reasons. It is common sense to soak glazed tiles in water before laying them, but there is no standard soaking time. Some high-quality ceramic tiles need to be soaked in water for at least 5 hours due to their high density on the bottom, which further tests the workers' sense of responsibility.
3. Solutions to the cracking phenomenon of different ceramic tiles
1. Ceramic tiles have poor pressure resistance
Be sure to identify the brand and origin when purchasing, which will greatly reduce risks.
2. The cement label is too high
During construction, be sure to follow the laying instructions of the ceramic tile brand, mix materials in the correct proportions, and mix evenly. According to technical requirements, cement and sand should be 1:2 or 1:2.5, which can ensure the strength of the paste without shrinking too fast during the drying process.
3. There is a problem with the wall base
Before laying bricks on a light wall, first, ask the construction personnel to inspect the wall to see whether it is firmly installed and whether it is suitable for paving; secondly, it is recommended to make a layer of steel wire on the side where the wall tiles are paved. Net, improve the strength and load-bearing capacity of the wall.
4. Ceramic tiles are located at the pipes
Tiles at pipe locations must be netted before laying.
5. Insufficient soaking of glazed tiles
Generally, the packaging of ceramic tiles will indicate in detail the precautions for the construction of the ceramic tiles, and workers should read them carefully before laying.
After reading the above detailed introduction, you will probably understand What causes ceramic tile cracking. The above content also introduces in detail, for different ceramic tile cracking phenomena, we will Then we can solve it with different methods. Then the above is the content shared today.
