People still think that smooth floor tiles are not easy to fall off frequently, but it is not. Improper actual operation during interior decoration makes it easier for floor tiles to often crack. It doesn’t matter who is held accountable, the root cause of the cracking of the floor tiles;
1. The cracking of the floor tiles caused by the wall deformation, there will be some horizontal, vertical or There are regular cracks diagonally. Safety precautions: Before laying bricks on the walls, please ask the decorator to inspect the walls to see if the walls are firmly installed; in addition, it is recommended to add a layer of wire mesh on the side of the bricks to increase the compressive strength and resistance Power capacity. For the thermal insulation wall, the thermal insulation layer is usually made of polystyrene board raw materials. The original thermal insulation wall can be removed and replaced with wall tiles. Taking into account the strong adhesion of wall tiles, it can reasonably and effectively reduce the cracking and cracking of floor tiles, but the actual effect of thermal insulation will be slightly worse. You can also hang an extra layer of wire mesh on the polystyrene board, and then use the cement pressure board or the corrugated magnesium board to pave the wall tiles on it.
2, the quality of the adhesive is not enough Phenomenon such as wall hollowing and cracking. Traditional paving wall tiles usually use mixed mortar as an adhesive. Concrete and mortar are usually proportioned according to the ratio of 1:1. If your proportion is uneven, the mixed mortar will not achieve the required adhesion. The actual effect; in addition, excessive sand content, use of inferior products or expired concrete will lead to inadequate adhesion, resulting in wall hollowing and cracking. Safety precautions: Remind many customers to use formal and reliable decoration company and standard processing technology raw materials.
3. Floor tiles that have not been soaked in water and have a certain water absorption rate, if they are not soaked in water before paving, they will condense in the mixed mortar after paving, and the compressive strength will decrease. In the whole process, the ceramic tiles will digest and absorb its moisture content, resulting in the lack of water in the concrete and the lack of adhesion. The compressive strength is reduced, and the adhesion of the brick to the concrete or the concrete to the original wall is reduced, resulting in frequent wall voids. Drum, cracking. Safety precautions: Use mixed mortar to pave the wall tiles (mainly refers to the wall tiles), and the floor tiles must be soaked in water for about two hours in advance. The higher the relative density of the bricks, the better the quality of the product, and the shorter the time to soak in water. The principle of thin paste does not need to be soaked in water, and the dosage mortar used contains a very large ratio of active ingredients in the paste, which is highly water-soluble.
4. There is no seam between the floor tiles. Causes floor tiles to be crushed and cracked, and walls are hollow or cracked. Safety precautions: floor tiles and joint fillers will both expand and contract with heat, and sufficient gaps should be left during paving; joint fillers are flexible products with high compressive strength , It fills up the thermal expansion coefficient of floor tile thermal expansion and contraction, which can avoid wall hollowing and cracking to a certain extent.
5. Floor tile products are of poor quality. Some low-quality floor tiles are not hard enough. If the force is too high during the whole process of use, they are more likely to crack (mainly refer to the floor). brick). Safety precautions: self-select brand products. The hardness standard of floor tiles is directly related to the relative density. When selecting, turn the tiles over to understand the opposite. The finer the particles, the greater the relative density of the floor tiles, the greater the hardness standard, and the better the product quality; Sprinkle water on the reverse side of the brick. If you do not seep underwater but flow down, it means that the relative density of the floor tile is very high and the hardness standard is very high; if the water seeps, it means that the floor tile is dense.
