Generally, as long as the construction technology and methods are correct and meticulous, there will be no quality problems if the size of the wall tiles is larger. Now the construction technology can fully meet your needs, just let the construction personnel do it carefully. Construction methods are attached for reference:

Tile installation methods and precautions:

Before laying tiles, the base layer should be cleaned first, such as lime plaster, latex paint, wallpaper and other decorations on the wall. , or there is dirt on the ground, be sure to clean it up, otherwise the cement mortar will not be firmly bonded to the base layer; in addition, if there are cracks in the wall itself, they should be properly handled before laying the bricks to avoid the basic structure cracks from getting bigger in the future. Wall tiles are cracked or peeled off; also, for floors and walls with a large difference in flatness or verticality, cement mortar must be used for leveling. Before laying, compare the color differences of the tiles.

Secondly, the wall tiles must be fully soaked in water. Because wall tiles have a high moisture content, this characteristic must be taken into consideration when pasting them. The base layer should be fully watered and moistened before tiling, and the tiles should be soaked in water for at least 20 minutes and then fully dried before use. Otherwise, the moisture in the mortar will be quickly absorbed by the dry base layer and ceramic tiles and condense quickly, which will affect its bonding fastness. Otherwise, the wall tiles will absorb moisture from the cement, making the cement unable to act as an adhesive.

To lay floor tiles, you need to use cement mortar to smooth the ground first, then lay the floor tiles without cement on the ground. After knocking them flat, apply the cement slurry all over the floor tiles and spread them on the ground. The diagonal corners of the four bricks The position is flush. The order of laying is also particular. Floor tiles should be laid from the inside out. If the ground has a slope or there is a floor drain, attention should be paid to finding the slope in the direction of drainage; wall tiles should be laid from bottom to top. For the sake of appearance, the bottom tiles should be laid last. After laying the wall tiles, lay down the floor tiles. In addition, one wall cannot be attached to the top at one time to prevent the ceramic tiles from collapsing due to their heavy weight. Do not step on the floor tiles for a short time after laying them.
