Wall tiles and floor tiles cannot be mixed: indoor tiles are divided into wall tiles and floor tiles according to the paving site. Strictly speaking, the wall tiles are pottery products, and the floor tiles are usually porcelain products. Their physical properties are different. There is a big difference between the selection of clay ingredients and the firing process. The water absorption rate of wall tiles is about 10%, and the specific water absorption rate is only 1% of floor tiles are several times higher. The floor of the bathroom and kitchen should be laid with low water absorption floor tiles, because the ground will often use a lot of water to wash, so that tiles can not be affected by water vapor, do not absorb stains. Wall tiles are made of glazed ceramics and have a high moisture content. The back of the wall tiles is generally rough, which also helps the adhesive to attach the wall tiles to the wall. Tiles are not easily affixed on the walls. Wall tiles used on the ground will absorb too much water and become difficult to clean. It can be seen that walls and floor tiles cannot be mixed.
Shop before leveling
The foundation should be cleaned before tiling, for example, lime plaster, latex paint, wallpaper, etc. on the wall, or dirt on the ground, must be cleaned, otherwise the cement mortar and the grass-roots layer will not be firmly bonded; in addition, if the wall itself Cracks should be made after proper treatment before tiling, so as to avoid future basic structural cracks leading to cracking or detachment of wall tiles; and cement walls to be napped, for floors or walls that have a large gap between flatness or verticality , but also use cement mortar for leveling treatment.
The order of laying stress
Posted floor tiles should be from the inside to the outside, such as the slope of the ground or there are leaks children, should pay attention to the direction of the drainage slope; wall tiles should be laid from the bottom, for the sake of beauty, the bottom of the brick should be posted. After pressing the tiles, press the floor tiles. When there are half bricks, you should try to place them below. In addition, a wall cannot be attached to the top at a time to prevent the tile from being heavy and causing it to fall.
Wall tiles should be fully soaked
Wall tiles have a high moisture content and must be considered when pasting. The tile base should be fully moistened before it is tiled, and ceramic tiles should also be soaked in water for at least 20 minutes before use. Otherwise, the moisture in the mortar is rapidly absorbed by the dried substrate and tiles and condenses quickly, which affects the fastness of the bond. Wall tiles will also absorb moisture from the cement so that the cement does not function as an adhesive. In addition, the water absorption rate of each type of wall tile is not the same, which depends on the experience to grasp.
Tile selection
Pay attention to its crack resistance and strength. Good quality tiles have low water absorption. The surface of the tile with poor resistance to glaze cracking, low strength and high water absorption is prone to irregular fine cracks, which are commonly referred to as late cracking or crushing and spalling. Therefore, the consumer can drop water on the back of the tile to observe the degree of diffusion and absorb water slowly.
Tile selection
It is necessary to pay attention to whether the surface of the tile is smooth and whether uneven pinholes occur. Tap the tiles when you buy, and listen for the crispness of the sound. The more brittle the sound, the higher the texture density of the tiles and the better the hardness. And can scratch the surface of the tile with a hard object, if there is a scratch, it indicates insufficient glazing. When the glaze on the surface of this tile is polished, it is easy to hide and it is difficult to clean.
Tile selection
To compare color differences. If the tiles have a significant color difference, the decoration effect will be affected. Because the number of ceramic tile purchases is relatively large, it is necessary to compare the samples of each package and observe the changes in the color difference. Generally, the color difference cannot be selected.
Tiles are to be checked for size. Tiles with large errors in size and flatness not only increase the difficulty of construction, but also have poor results after renovation. The common size of floor tiles is a 400-600mm square format, and sometimes even large-format floor tiles of 1000×1000mm are used. The size of the floor tiles should be chosen according to the size of the space. A small space cannot use a large size, otherwise it will have a disproportionate feeling. Spaces such as the general living room can be selected with larger floor tiles, and 300-400mm floor tiles should be used in the kitchen, bathroom, etc., but care should be taken to prevent slippage, wear resistance, and easy cleaning.
