Tiles are popular with the public because they are aesthetically pleasing and very easy to clean. Most home decorators choose to tile. However, many owners found that after they had checked in, they found that the tiles in the house had encountered a hollowing phenomenon. They would even fall off seriously, causing great safety risks to our home. They also affected the beauty of the home. What caused the tiles to be empty? Drum? Next Xiao Bian analyzes the reasons for the emptying of several tiles , and tells everyone how to solve this problem.
First, check if the tiles are empty
You can tap the tile with a small iron bar, and you can quickly determine if there is a hollow drum imagination by tapping the sound. If it is a relatively boring percussion sound, it proves that the tile is firm and there is no problem. The percussion sound is a “squeaky†sound, which proves that the tiles are not solid enough and there is a hollow phenomenon.
Second, the reasons for the empty tiles
1, the construction method is not standard, resulting in empty tiles
Wet-laid tiles can easily cause hollowing. Because of the high moisture contained in the mortar, some voids are easily formed during the drying process, which results in the ceramic tile not fully bonding with the base layer, resulting in empty drums. In order to save time and materials, some construction teams do not have sand ash in the middle, and only apply sand tiles to the four corners of tiles to lay tiles. Just after the tiles were laid, the tiles looked solid, and as time went on, the tiles would have caused druming because of different expansion coefficients.
2, thermal expansion and contraction led to empty tiles
The temperature changes in the early and late autumn and winter are relatively large. If the ceramic tile is not completely dry, the temperature of the tile will suddenly drop. This situation will cause the ground to freeze, so the moisture in the mortar cannot completely dry. When the temperature rises during the daytime, due to the principle of thermal expansion and contraction, the floor tile shakes with the ground floor, and then it loosens, falls off, and finally becomes empty. There are also many external reasons, such as the effect of external forces, deformation of the floor tiles, and poor quality cement, all of which contribute to the emptying of the floor tiles. This will not be introduced one by one here.
Third, how to do empty tiles
1. The reason for the emptying of floor tiles is that the cement is not filled when it is laid, resulting in air bubbles and empty drums between the tiles and cement. This solution is to immediately look for the master to re-pave it without considering other things. Method. It is very common to use a dry shop method that is to remove the floating sand and debris after wetting the grass roots. Use one to three dry cement mortar as a bonding layer, lay flat along the horizontal line, put the brick on the mortar and use a rubber-coated hammer to tap, and then remove the floor tile to pour the cement slurry, and then put the floor tile to make it level. .
2. If more than one-third of the paving tile area is empty, it is recommended that the entire tile be removed and re-paved. Because this is a loss caused by the construction side, from the standard point of view, it may be considered that the construction party should bear the cost of tile damage and artificial accessories.
The article concludes: The causes and solutions for the hollowing of the tiles are introduced here for everyone. No matter what causes the empty drum phenomenon, as long as it will endanger the safety, it must be handled as soon as possible so as not to cause unnecessary s damage. We also have to choose the tiles of the regular brand as early as possible when purchasing tiles. The flatness and thickness of the tiles are more formal and can reduce the emptying rate.
