The reason of the floor brick rising
expansion gap between floor tiles is too narrow
When the indoor temperature changes dramatically, the floor, cement layer and ceramic tile will show the phenomenon of heat expansion and cold contraction. If the gap between the ceramic tiles is too narrow, there is not enough extension space, it will be warped due to extrusion. In general, this kind of situation is easy to appear in the dry north with large temperature difference.
Proportion error of cement in laying floor tiles
To know when laying ceramic tile, it depends on a certain proportion of cement and sand mixture to act as a binder. If the mixing ratio error is large, for example, the cement grade is low, the yellow sand is put much, and the time is long, the cement in the lower layer will not be able to adhere to the floor tiles, causing the situation of upwarping.
The cement floor is too smooth
If the original cement floor is too smooth, it is not roughened. The floor tiles laid in this way are easy to rise.
How to solve the problem of floor brick rising

2. Mix cement and yellow sand in a certain proportion, and make sure to mix well. Experts suggest that the laying of floor tiles should pay attention to the use of more than 425 cement, sand should be filtered drips of medium coarse sand, according to 1:2 ratio, and reserve 1 mm expansion joint.
3. Fill in the space with the mixed adhesive and pave it with a layer, the thickness shall be subject to the surrounding degree. To avoid laying too high or too low.
4. After that, put the tiles out and compact them to be consistent with the surrounding height.
Tiles are not completely loose
In this case, the difficulty of handling is that when taking out the tiles, it may cause damage to the floor tiles, so it is necessary to have spare floor tiles, or contact the seller to purchase floor tiles of the same color number. Break the floor tiles from the middle, use crowbar to pry the damaged tiles carefully from the middle to the surrounding, so that the treatment will not cause damage to the surrounding tiles. After the tiles are taken out, then handle according to the method of the above surface.
In addition, it can be treated by grouting, that is, the cement paste mixed with 108 glue is infiltrated into the bottom of the tile from the gap of the tile. (this kind of treatment method is a way to cure the symptoms but not the root cause. It can't completely solve the problem of loosening of ceramic tiles, which may still occur after a long time. ）In addition, after the ceramic brick has been treated by the above method, do not walk and trample on it before the ceramic brick is dry and solid!
