Decoration knowledge Why are the tiles uneven

As we all know, cement mortar is generally used for tiling, but in recent years, there have been more tile adhesives on the market, and I don't know which one is better to use!

Let's look at the cement mortar first, that is, it is mainly cement, add yellow sand and some waterproof additives, and then stir with water, which is basically zero pollution, high adhesion, and preferential treatment.

But the bad thing is that cement mortar is affected by many external factors and is easy to fall off. In addition, the hardness of tiles on the market is getting higher and higher, and the focus is on poor water absorption, so the tiles often fall off.

From the appearance, tile adhesive and cement are almost the same, mainly mixed with water, and then directly used to paste tiles. However, tile adhesive has an advantage that cement does not have, that is, it is less affected by external factors, and it is resistant to low temperature and water. The bad point may be that it is expensive, and there are many bad tile adhesives on the market, and there may even be the problem of excessive formaldehyde.

Compared with cement and tile adhesive, the adhesive performance of ceramic tile adhesive will be better, the point is that you don't need to run the tile in advance, you can paste it directly. There is no need to paint a thick layer on the wall, and it is basically very firm when pasted on.

Of course, good things are generally expensive, so there is no need to use tile adhesive in all places, you can use it in the kitchen and bathroom, because these places are often wet, and it is easy to fall off with general cement.

Zhengzhou decoration company found that the owners generally pick cheaper ones when they choose, so that the quality of the tiles is difficult to guarantee, and even small factories without business licenses are produced. The tiles produced by the small factory will have tile warping corners, sometimes you can't see it, but the four stickers are obvious, and the four corners are uneven, so what should we pay attention to when choosing tiles? Zhengzhou decoration company has the following suggestions when choosing tiles:

1. The tiles placed in the exhibition hall of the building materials market are carefully selected bricks by the merchants, but the bricks sent to the construction site may not be so, so any four bricks can be spliced into a square during the inspection, and check whether the corners are flat and whether there is a warping angle. 2. Generally speaking, the error of seamless brick is the smallest, and the error of antique brick is large, and the size of the tile should be inspected when selecting the tile. 3. Tiles are fragile products, and the corners are easy to be damaged during transportation.

In particular, the four corners of the two bricks placed on the outermost side should be inspected. 4. Don't go to the market too far from the construction site to buy tiles. Because it is inevitable to make up or return bricks, it is recommended to buy with the principle of "buy more, not buy less", because if you can't make up the bricks of the same color when making up the bricks, it will affect the overall inlay effect or the delay of the construction period.

Zhengzhou decoration company will introduce you to several ways to judge the quality of tiles: 1. It is better to beat with a crisp sound, and the crisp sound indicates that the density and hardness of the tiles are high, and the lower the water absorption rate, the better the stability of the tiles, that is, suitable for places with high moisture or moisture content. Zhengzhou decoration company reminds you:

Pour a glass of water on the back of the tile to see the speed of water absorption, the faster the diffusion speed, the higher the water absorption, and vice versa, the lower the water absorption. 3. Look at the appearance and look at the grade. The superior products are the best, and the third-class products and other foreign products are worried; Second, look at the appearance and glaze.

Good tiles have no convex and concave, bulging, warping corners and other problems, and the edges are straight and flat. The glaze is smooth and clean, without particles or different shades of color; Third, look at the pattern. The pattern should be delicate, without obvious color leakage, misalignment, broken lines or different shades.

4. Look at the cut surface and cut out the tile fragments (generally you can ask the store for broken fragments to observe), and look at the fractures. The fracture is fine, hard and brittle, and the color is the same as that of the top grade.

The main reasons for the unevenness after tile paving are as follows:

1. The dry ash layer under the tile is hammered to form a settlement in the process of drying and solidifying, the dry ash layer absorbs the moisture in the cement mortar on the back of the brick, and the dry ash layer is not hammered to form a settlement, resulting in an uneven brick surface.

2. The cement mortar coated on the back of the tile is not full and uniform, so as to form a porcelain brick paving hollow drum, and in the process of dry solidification, the force of the hollow drum on the brick and the force of the part without the brick are inconsistent, resulting in uneven tiles;

3. The tile is not dried and solidified before the joint treatment, because the tile is not completely dry and solidified, it is a joint filling material in the brick joint, so as to form the uneven height of the tile;

4. Walking and stepping on the brick surface or other construction operations before the tile is not dry and solid, when the tile is not dry and solid, walking and stepping on the brick surface may cause loosening and unevenness.

In addition to the problems of the tiles themselves, the worker paving is a particularly important link, the cement mortar, including the technique. Therefore, it is especially important to find a good worker.

Generally, there are two reasons for uneven tile paving, one is that the quality of the tile is not good, and it is not very flat, so you will not be flat no matter how you paste it; The second is the craftsmanship of workers. The cement is not evenly paved, and the pressure is uneven when paving, and the effect of pasting will appear uneven. Therefore, you should not only choose products of qualified quality when purchasing ceramic tiles, it is best to go to a guaranteed store such as B&Q to buy, but also find a master with good craftsmanship.

Now there is the kind of uneven brick that is specially made, which is very artistic.

Decoration is definitely a technical job!

1.Base problem: If the surface of the base is uneven, such as uneven concrete or uneven wood planks on the ground surface, it will cause the tile to be uneven after paving.

Before applying the tiles, the horizontality and verticality of the base should be checked, and if there are uneven areas that need to be treated, such as tamping the ground with wooden planks to achieve leveling, or filling concrete to level the ground.

2.Problems with the tiles themselves: Tiles may be hit or damaged during production and transportation, and these damages may cause uneven tile surfaces. Inspections should be carried out before tiling and if problems are found, they should be replaced.

3.Tile paving process problem: Paving ceramic tiles is a technical work, which requires tile workers to have certain skills and experience. If the worker's operation is not standardized, not careful, the tools are not appropriate or the technology is not up to standard, it also means that the bridge will lead to uneven tile paving.

4.Tile paving material problems: If the quality of the cement mortar used to pave the tiles is not good, or it is not calm enough, it may lead to uneven tiles after paving, and even hollowing.

If the tile is not paved, the cause of the problem should be found first, and then the correct treatment should be carried out. Before laying tiles, you should ensure that the surface of the base layer is flat, use high-quality tile paving materials, and ask qualified tile workers to operate, so as to avoid the problem of uneven paving to the greatest extent. I hope I have done something to you, and I wish you a happy life
