What are the common sense of tile paving?

Improper operation during paving, unqualified construction level, and inattentive supervision and acceptance can all cause problems in the future life of ceramic tiles. Therefore, whether you are buying bricks or selling bricks, the following basic paving common sense is worth checking out. Keep the joints of the tiles, because the tiles will expand and contract under the influence of the environment. The reserved joints can prevent the adjacent tiles from squeezing and emptying and falling off. In addition, the remaining joints of the tiles can also reduce the uneven joints and uneven paving caused by the error of the tile size and the manual operation error. Paving direction For tiles with obvious texture, in order to ensure the visual effect after paving, you need to pave in the direction of the arrow on the bottom label of the tile. Otherwise, the texture may not match up, and it may also cause unevenness. Ceramic tiles must be soaked in water to prevent the embryo body from absorbing the moisture in the cement mortar after paving and affecting the adhesion. Soak in clean water for more than 2 hours before paving, and take out the brick to dry for later use, as long as the brick does not bubbling. When cleaning the back mortar tile factory, it is easy to form a layer of white powder on the back of the tile. This layer of powder will form a barrier layer during paving and affect the contact between cement mortar and bricks, thereby reducing the bonding strength. Therefore, it must be treated carefully before paving, and scrubbing can be carried out before and after soaking if necessary to ensure that there is no residue of mortar. The correct approach should be: on a horizontal base surface, use a toothed scraper to evenly form the tile glue into a toothed layout. Note that for tiles of the same color number, different batches will have a certain color difference. The manufacturer will divide tiles of similar colors into the same color number through color separation. Workers who do not pay attention to the color number when paving will result in obvious color difference between adjacent tiles. In addition, some owners did not calculate the quantity when purchasing ceramic tiles, which led to the need to re-purchase later. If they did not pay attention to choosing products with the same batch number and color number as the original product, slight color difference may also occur. After the jointed tiles are laid, it is best to do the jointing treatment after 24 hours, and evenly apply the pre-prepared jointing agent to the gap between the tiles. In pursuit of beauty, if you have enough budget, you can also use beauty seam agent, with better color and performance. The external angle is the protruding angle formed by the two walls. When laying tiles, chamfering is generally used, that is, the edges of the tiles are cut on the back of the tiles to form a 90-degree right angle, and the external angles are wrapped. For example, directly insert the opening in the middle of the tiles. The correct approach should be: cut the tiles into four diagonally, and when paving, the tiles around the floor drain form a groove at a certain slope, and the floor drain is embedded in the center. Water absorption rate should be paid attention to the water absorption rate of tiles laid on the kitchen, bathroom and other wet areas. If the water absorption rate of the tiles is too high, it is easy to turn yellow and color difference due to excessive water inhalation after paving. Cutting tile cutting is also a problem-prone link, and the cutting size and cutting method require precise operations. If the workmanship is not superb, the surface of the tiles may be darkly cracked when the tiles are cut by hand. If more cutting operations are required (complex paving scheme or parquet), it is recommended to use professional equipment for processing. Cement mortar ratio The key to cement mortar adhesion is the ratio of cement and sand. The paving master suggested that 1:3 cement mortar can be used for floor tiles, and the mortar should not be too thin; wall tiles can be used at a ratio of 1:2 or 1:1, and for floor leveling, 1:1 cement mortar can be used, and pure The cement slurry is collected. Cement mark The mark of cement mortar indirectly affects the setting effect between it and ceramic tiles. If the mark is too low, it will cause the tiles to separate directly from the cement mortar, and the tiles will appear hollow. Purchasing cement according to standards, it is generally recommended to use No. 452 cement, that is, No. 32.5 cement. The basic treatment of the wall and ground is a very important work. Before paving, the basic level must be cleaned to ensure that all kinds of dirt and plaster are removed. It is best to wet the basic level with water the day before paving, and the humidity should be controlled at 30-70. %. Waterproof toilets, balconies and other spaces must have a waterproof layer before tiling. If the original waterproof layer is damaged during the construction, it must be re-waterproofed, and the accumulated water must be tested for 24 hours without leakage. The cutout of the wall outlet must be suitable, otherwise the opening is too large to expose the pores and be unsightly. Cut the round if it is round, don’t cut the square hole to find it ugly.
