The cement mortar is very uniform during construction, why do the tiles still fall off? What can be

It is very likely that the quality of the sand is not very good, so it causes the tiles to fall off, so you can ask a professional construction team to repair the glue.

There are many reasons why tiles can fall off. It has a certain relationship with cement mortar, but it is also likely to be a problem with tile adhesive, and tile bonding should be re-done.

The texture of the two is different, and the construction process is also different. As the name suggests, glazed bricks are coated with a layer of glaze on the bottom of the blank, the bottom of the blank may be porcelain or pottery, the pottery body needs to be soaked in water, the polished brick body is a porcelain body, the surface is polished with a machine, the density is very high, the water absorption rate, and the construction does not need to soak in water. 2. Grassroots issues.

There are also several kinds of attachment base of wall tiles: aerated block plastering wall, concrete plastering wall, cement pressure plate plastering wall. Among them, aerated blocks and concrete wall plastering require traditional construction technology spraying.

Remedy 1: Tile local hollowing, if it does not affect the normal use of furniture, people who do not have high requirements for aesthetics, can not do remedy, otherwise it will fall off more, if it is affected, then the best way is to remove it all and redecorate.

Remedy 2: When removing the tiles, it is not destroyed casually, and generally should be slowly lifted from the middle of the tiles to the surrounding sides, so as to prevent damage to the surrounding tiles.

The tiles and cement fall off together, how to solve it?

Dear, hello, I am glad to answer for you: the tile and cement fall off together, how to solve it? A:

If the tile and cement fall off, if it is a small area falling off, you can not plane the wall, directly paste with structural adhesive, or marble glue to paste, so that the height will not be too obvious. In addition, it can also achieve a strong paste. If a large area is planed off and redecorated, you can choose tile adhesive and the like to visit relatives is also very firm, you can use tile adhesive, its main feature is that it is more viscous and more water-resistant, and during construction, as long as the uniformity is coated with a layer of glue, you can pretend to be blind to fix the tile, and the operation is relatively simple; Compared with the traditional process, the use of tile adhesive will also be more affordable.

The specific operation step is to stir the glue and apply it to the back of the tile, and then apply the reed missing tile to the base surface. This pasting method is more likely to produce the problem of vacancy, which can easily lead to the problem of silver removal and empty fall of the tile in the later use process, so it is not recommended to use it.

Wall tiles can play a good decorative role, and it is easy to use and easy to take care of, so many families will choose this decoration method, but because there are many ways to paste tiles, cement is the most common one, and fine sand is usually added to improve strength. So, will the pure cement sticker fall off? What should I pay attention to when pasting wall tiles?

Let's take a brief look at it together.

1. Will the pure cement wall tiles fall off?

It will not necessarily fall, but the use of pure cement wall tiles, the probability of tile falling off is very large, because although pure cement has a good cementing ability, but its shrinkage is very large, after the cement is dry, it will bring greater tension to the tile, so the tile is prone to hollowing.

or cracking, etc., the wall tiles may fall off after a long time, so it is recommended that it is best not to use pure cement to stick the wall tiles.

Second, what need to be paid attention to when sticking wall tiles.

1. Before pasting wall tiles, you need to soak the tiles in water one day in advance to let the tiles fully absorb the water, otherwise after pasting the wall, it will absorb cement mortar.

The moisture in the cement mortar affects the adhesion of the cement mortar, resulting in the hollowing of the tile.

2. Usually cement mortar will be used for tiles, this proportion is not fixed, and appropriate adjustments need to be made according to the actual situation, otherwise the wall tiles may fall off or crack because of the improper proportion, usually adhesive.

The ratio is 1:3.

3. Because ceramic tiles are easily affected by the environment, they are prone to thermal expansion and cold contraction.

Therefore, when paving wall tiles, be sure to reserve expansion joints of suitable size.

However, it is important to ensure that the gaps are horizontal and vertical, so as to ensure the service life of the tiles.

4. In the process of paving tiles, it is necessary to wipe off the overflowing adhesive material in time, otherwise after the material is dry, it can only be scraped off with special tools, which is easy to damage the brightness of the tile surface, and pay attention to scrubbing the surface with a wet rag after scraping.

Summary: The above about whether pure cement wall tiles will fall off, as well as the precautions for wall tiles, I hope it will help you.

The cement mortar on the back of the tile is very uniform, why there is still the problem of the whole tile falling off, this topic bothers many people, today for you to analyze the cause of the problem. The cement mortar on the back of the tile is very homogeneous. Why do tiles fall off in their entirety?

Let's start with the material. Whether it is home decoration or tooling, wall tiles are generally divided into two types: glazed tiles and polished tiles in terms of texture. The two materials are different, and the construction process is also different.

Glazed tiles, as the name suggests, are painted with a layer of glaze on the bottom of the slate. The bottom of the slab may be tiles or terracotta tiles, and the terracotta tiles need to be soaked in water. Polished bricks are tiles whose surfaces are polished by machine.

The density is very high, the water absorption rate is high, and there is no need to soak in water during construction.

The wall is not sufficiently moistened before masonry, resulting in the cement mortar and the moisture in the brick body being absorbed, and the mortar does not have enough humidity during the setting time to fully bond the tiles. Wet the base layer with water before paving, and control the humidity at 30-70%. Tiles are ceramic products made of natural clay, which expand and contract with the change of temperature.

If there are no seams, the tiles will squeeze off each other. Generally, a 1 2mm seam should be left, just like the cement pavement must be cut to leave a seam.

For the former tiles, according to the current category of tiles can only be regarded as "tiles", but not tiles at all, that is to say, can not meet the requirements of the current tiles, so this kind of tile means that the soil composition is very large. After paving with cement mortar, the "tile" can be well bonded with cement mortar and will not fall off.

For the current wall tiles, unless they are full tiles, do enough soaking work before pasting them to fill the inside of the tiles with moisture. In this way, when pasting on the wall with cement mortar, the tile will not accelerate the absorption of moisture in the cement mortar, so that the tile will be pasted firmly and will not fall off. On the other hand, if the tiles are attached to the wall before they are laid, or if they are soaked for a short time, then the tiles will quickly absorb the moisture in the cement mortar, causing the tiles to fall off.

It is because the tiles have been severely damp, and the air in the room is too humid or moist, causing the cement to fall off, although it is very evenly smeared, but the waterproof coating is not done.

This is because the quality of the cement is not very good, the viscosity is not very large, or the ratio of water and cement is not good, which causes the tile to fall off.

It may be that the tiles are not wet when they are pasted, or it may be that there is some ash on the bricks.

<>1. The base layer of the wall is not cleaned

The base layer of the wall must be cleaned to remove all kinds of dirt from the wall. If it is not cleaned up, the moisture of the tile adhesive will be absorbed by the dust and build-up deposits of the base layer when the tile is pasted, and hollowing will occur.

Even if the tile bonds well to the tile adhesive, it will come off!

2. The wall tiles are not soaked before paving

Generally speaking, the water absorption rate of ceramic tiles is greater than 10%, in order not to be absorbed by the tiles when pasting tiles, resulting in a decrease in mortar adhesion. Therefore, before pasting the tiles, the tiles will be soaked. If you stick it directly without soaking, it is likely that the tile will fall off.

3. The water absorption rate of ceramic tiles is unqualified

The water absorption rate of ceramic tiles is too high and too low, which is easy to cause the tiles to fall off. The water absorption rate is too high, the density of the tile blank is loose, it is easy to absorb water, and the tile is expanded and contracted by heat.

After that, it will lead to cracking of the surface and even peeling off of the whole tile. The wall tiles with too low water absorption rate are difficult to absorb the moisture in the tile binder, and the adhesion between the tile and the cement cannot be formed, and the chance of falling off will be greatly increased.

5. The wall foundation is not watered

In the same way that tiles need to be wetted, the walls are also wetted when tiles are pasted. If it is not wetted, the moisture of the binder will be absorbed in large quantities, which will change the properties of the tile binder and leave a hidden danger for the future.

6. The tile seam is not enough

All kinds of wall tiles will expand and contract with the change of temperature, if you do not reserve a certain gap when laying tiles, it is possible that when the temperature around the tiles changes, there is a phenomenon of mutual extrusion and cracking. Therefore, when pasting tiles, there will be a gap of 1 2 mm between the tiles and the tiles.

7. Secondary percussion

Many people find that the tiles are uneven after paving, and they will be knocked flat twice, which will cause the mortar that has lost part of its moisture to loosen, thus causing the tiles to fall off.

8. The tile adhesive is not evenly applied

When the tile is pasted, the tile adhesive on the back of the tile should be applied evenly. Some of the irregularities are to apply only the middle of the tile, or only the corners or periphery. If the application is uneven, there will be a hollowing phenomenon, and after a long time, it is easy to fall off the tile.

9. Be sure to choose high-quality tile adhesive

The tile adhesives on the market are uneven, so be sure to choose high-quality tile adhesives. Unqualified tile adhesive has poor adhesion, or poor sag resistance, or poor aging resistance, which can easily cause the tile to fall off.

There are so many doorways for seemingly simple tile pasting, and pasting tiles is not only to find a good craftsmanship but also a sense of responsibility.

The master is done, and the choice of tiles and tile adhesives is also very important!

It may be that the quality of the choice is relatively poor, and it is caused by choosing the right cement, and you can choose tile adhesive to avoid the problem.

There is a problem with the ratio, there is a problem with the selection of materials, and if you want to solve this problem, you need to pay attention to the selection of materials.

It may be that there is a problem with the ratio of cement, and some other special materials are not added to it, so you must choose the right material.

In the past, cement mortar tiles did not fall bricks, why do cement mortar tiles fall a lot now? What are the similarities between the use of mixed mortar to stick the floor tiles and the previous mixed mortar to stick the floor tiles; The application of mixed mortar to paste the floor tiles and the previous application of mixed mortar to paste the floor tiles, their similarities I personally think have two points: one is the characteristics of the mixed mortar itself, and the other is the characteristics of the wall base.

Regardless of which of us are, the essence of these two aspects is actually the same. It is mainly manifested in the following two conditions.

The characteristics of the traditional hybrid mortar have not changed from the current hybrid mortar. The chemical composition of the traditional mixed mortar is mainly cement sand, followed by adding a certain amount of cold water, and finally mixed or stirred. At present, the mixed mortar is the same or mixed with cement, sand and water according to a certain ratio.

Therefore, the mixed mortar does not do all the changes in nature, and naturally it will not harm the adhesion of the floor tiles and the situation of falling bricks.

The bottom layer of the wall has not been transformed. Traditionally, mixed mortar is used to stick to the wall tiles, and most of the bottom layer of the wall is dominated by the overall surface layer of mixed mortar. At present, mixed mortar is used to stick to the wall tiles, and the bottom layer of the wall is the same or dominated by cement grout.

Whether it is the overall surface layer of some special structures, there has been no other transformation before and now. Therefore, from this point of view, it will not jeopardize the sturdiness of the mixed mortar adhesive floor tiles.

The needs of the floor tile back have not changed. In other words, whether we have used mixed mortar to stick the floor tiles before, or we are currently using mixed mortar to stick the floor tiles, we must rinse the back of the floor tiles with tap water before pasting. If there is a release agent on the back of the floor tile, the release agent should be polished and polished before it is allowed to be pasted.

Therefore, from this point of view, it is not the cause of the bricks falling after the mixed mortar sticks to the auspicious paste.

Summary of the situation: through the above three points for the introduction of cement mortar, wall base and tile back treatment, in fact, you can also understand that the reason why we use cement mortar to paste the wall tiles at this stage is not related to the cement mortar and the base of the wall, and it also has little to do with the back treatment of the tile. Therefore, at this stage, after the cement mortar is pasted, the wall bricks fall off, we must first rule out the cause of the cement mortar itself, as well as the reason for the wall base layer, as well as the factors of the back of the tile.

It is because the current climate is not particularly good, and it is particularly easy to cause certain damage to the tiles, so it is easier to drop frames.

Now in the process of decoration, the hail bureau, do Shen has gradually replaced the cement mortar with tile adhesive. Just decorated, it will not fall bricks, but it is not durable, and it is easy to be pure and wanton after a long time.

This liquid is sold because some of the cement and mortar materials used now are not particularly good, and the decoration effect is not particularly good.
