When it comes to using ceramic tiles to decorate houses, the most worrying issue is that the ceramic tiles are unevenly laid. What do you think is the cause? Do you blame the decorator's poor skills or the blame? Tile quality is not good? Therefore, Mr. Zhongtao is here again today to share this knowledge with you! Then follow Zhongtao Jun to find out more!
1. The factor of poor craftsmanship of the decorator = human factor
1. The proportion of cement mortar is incorrect
Traditional paving generally uses cement and sand mixed on site as an adhesive. The ratio of cement and sand is very important. If the proportion is wrong, the proportion of sand is too high, or no adhesive is added to the mortar, the cement mortar will not stick to the ceramic tiles, causing the floor tiles to warp.
2. The paving direction is wrong
I learned earlier that each tile has a slight bow when it is produced. During production, the manufacturer has already given laying instructions on the back of the tile. This can ensure that: ① the surface texture of the tile is more smoothly connected, ② the texture of each tile is The edges are raised to a similar degree and are relatively flat when laid. If you don't follow the instructions on the back of the tiles to lay them correctly, the tiles will definitely become uneven.
3. Uneven application of cement mortar
When laying ceramic tiles, some bricklayers only apply mortar around the tiles to save time. As a result, only 3-5 cm of mortar from the edge of the tiles is adhered to the wall. Ceramic tiles with uneven stress are not only not firmly bonded, but may also be unstable later. smooth.
4. Use seamless paving or leave too thin seams when paving.
Almost every ceramic tile has slight deviations in length, square angle, edge straightness, etc. If no seams are left, when the height difference between the edges of the tiles is slightly larger, the seams will appear to be uneven. At the same time, seamless paving can easily cause the tiles to bulge or crack when they expand with heat and shrink with cold.
5. The tiles were not hammered down after laying them
After the tiles are attached to the ground, since the cement mortar is still in a semi-dry state, it is necessary to press the mortar downwards by tapping so that the cement mortar is evenly distributed under the tiles. This can avoid uneven stress on the tiles when the cement solidifies and affect the smoothness. Spend. Many times the paving workers ignore this step and fail to knock the bricks firmly.
6. Levels and vertical cones are not required during construction
Some masters do not use a level and a vertical cone for positioning when operating, thinking that visual inspection is enough. This is very irregular. The causes of uneven ceramic tiles include the ceramic tile's own factors, environmental factors, human construction and other factors. From these various reasons, it is difficult to changeIn addition to foundation problems, try to optimize the purchase of ceramic tiles and find an excellent and responsible construction master.
2. Ceramic tile’s own factors
1. The phenomenon of hunched back appears
Ceramic tiles are fired under high temperature and high pressure, and will appear more or less bowed. After precise selection by the machine, this bowing phenomenon will be within the standard limit and will generally not affect the paving. Therefore, when purchasing ceramic tiles, it is best to choose a large manufacturer such as the top ten brands of ceramic tiles. High-quality ceramic tiles produced under this kind of production efficiency and supervision can be purchased with peace of mind.
2. Tile warping angle
The main reason for the warping of ceramic tiles is that the ceramic tiles have not been completely burned. High-temperature materials are used in the ceramic tile formula. Many small manufacturers add low-temperature materials in order to burn faster. During the firing process, the burned low-temperature material wraps the high-temperature material, forming vitrification on the surface, but the internal material is not completely vitrified or porcelain. Therefore, after paving, due to the influence of cement tension and environment, rebound deformation will occur and warping will occur.
3. Environmental factors
1. Foundation deformation
Buildings will settle to a certain extent due to geological problems. Different locations will bear different forces and the degree of settlement will be inconsistent. Over time, the ground will become uneven and the tiles will become uneven.
2. Large temperature difference
The changes in temperature and humidity in the four seasons will cause the ceramic tiles to deform when the temperature is too low or too high. When the temperature in the north is too low in winter, the moisture in the cement mortar binder will freeze and expand in volume, destroying the structure and strength of the cement mortar. In this case, the ceramic tiles will become bulging. When ceramic tiles are exposed to high temperatures for a long time, they will also deform.
So if you look at the above Causes of uneven tile paving, they are caused by three factors. Therefore, based on the above three factors, you might as well find a skilled decorator and buy a good quality one. A little bit of tiles to fundamentally solve these reasons. Well, the above is what Zhongtao Jun has shared with you, so take a good look, and Zhongtao Jun will leave first!
