Because of the quality of bricks, or some irregular processes and processes in the construction process, there will be some more or less problems. Common chromatic aberration, tile diagonal error (tile size), cracks, etc.
Generally, when receiving the tiles, check the batch number of the outer package, or the size of the size indicated in the color code. Then, before the construction, pick a piece of flat floor or board and lay it out roughly to check whether there is color difference. Or tile size. Tiles and tiles have a color difference is normal, if you feel unacceptable, then do not apply decal tiles, return processing. If the size error exceeds a certain standard, then stop the construction in order to return or exchange. Please lay Note that some bricks with marbled patterns may have several colors, so you need to pick them before you lay them, and evenly position the flowers when laying them. Please follow the signs behind the tiles in the same direction.

crack
The phenomenon of cracks in tiles is generally due to the quality of the bricks. Because the walls do not have a stable dryness, the tiles are cracked due to deformation, and the tiles are not flooded. These three reasons cause how to avoid these problems. Look at the length of time after the capping of the new house to avoid the tile problems caused by wall deformation, including self-modification of the wall. Second, the tiles must be soaked before the laying, the general time is about 30 minutes, when the bubbles in the tiles are rarely seen, Yes. If it is the quality of the tiles, then see how you choose. On the quality of ceramic tiles, there is information available for reference.
Generally speaking, cracks on tiles can tell what causes the cracking. If it is a crack that runs through several tiles, it is basically the reason of the wall. If the brick body appears in every piece, for example, Occur in the center position, or a corner position, then it may be flooding is not in place, if it is a lot of bricks, scattered in the wall, and each piece of brick is a net-shaped cracking, then the basic quality of the brick.
This is generally the case for identification, but it still requires a lot of experience to check it out. After all, there are some difficulties in expressing the text. To avoid problems in the decoration, one is the quality of the bricks and the other is the quality of the construction.
Add a little. After the renovation is completed, there may be artificial breakage of the brick, please leave one or two pieces of bricks in order to prepare for the future wall drilled tiles broken, you can change, because it is very likely that You need to make up the bricks. The color number you need is no longer available on the market, causing chromatic aberration.
Cracking
The root cause of cracking is that the stress between the blank and the glaze exceeds the difference in thermal expansion coefficient between the blank glaze. When the glaze is larger than the billet's thermal expansion coefficient, the glaze shrinks more than the billet when cooled, and the glaze will be subject to tensile stress. When the tensile stress is greater than the ultimate strength that the glaze layer can withstand, cracking will occur.
Back osmosis
Regardless of the kind of brick, water absorption is natural, but when the density of the green body is too loose, it is not only the problem of water absorption but the problem of cementation. That is, cement sewage will penetrate the surface.
