After one year of use, what is the reason for the separation of the tile from the black cement? How

The first phenomenon is the separation of the tiles on the wall from the wall. That is to say, the whole tile has fallen off from the wall, and some of the adhesive materials on the wall are still well attached to the wall. This is what we often call the wall tiles themselves falling off.

The second phenomenon is that when the tiles on the wall fall off, there is a lot of adhesive material on the back. That is to say, when the wall tiles fall off, there is a large amount of cement mortar on the back of the tile, which is the falling off of the tile caused by the wall problem. The third phenomenon is that there are many cracks in the wall.

These cracks also cause the tiles to crack as well, and the cracking is very irregular, and as a result, many tiles are separated from the wall.

What are the reasons for the hollowing of wall tiles to fall off?

The first is the detachment of the wall tiles themselves. The reason why the tiles themselves fall off is that the adhesive material we use does not match the tiles we use. The problem most often occurs in the case of floor tiles on the wall, that is to say, we use the floor tiles as wall tiles, and the pasting material chosen at this time is ordinary cement mortar.

The floor tile itself is a low-absorption tile, and ordinary cement mortar cannot paste these low-absorption tiles, and the result of the later stage is that the tile is very clean and falls off from the wall. The second situation is the falling off of the tiles caused by the wall itself. The reason for the wall itself is mainly for the existence of plastering for the base layer of the wall.

For example, there is a serious lack of strength in the plastering of the base layer of the wall, and the phenomenon is that there is a large amount of sand and sand on the wall; In addition, there is a large area of hollow drum on the wall. The quality of these walls has not been dealt with, and the tiles are pasted on the wall, and the result is that the adhesive material of the tiles will directly bring the unqualified plastering mortar of these base layers directly from the wall. Tile detachment with adhesive material and cement mortar on the wall.

In this case, you can only take remedial measures. You can use nail-free adhesive to re-glue the tiles in their original positions, and the effect is also very good.

Answer: After one year of use, the main reason for the separation of ceramic tiles and black cement is that the tiles are not soaked in water before application, and the second is that after the construction is completed, the health is not in place, and the water is sprayed for a few days, at least seven days. The only way for this to happen is to start all over again.

The separation of the tile from the black cement may be due to the following reasons:

1. Grassroots treatment problems: the wall and ground base treatment is not clean, the watering wetness is not enough, the floating dust on the back of the tile is not removed, and too much water before paving will cause the tile and the wall to be bonded tightly, and it will loosen and fall off after a period of use.

2. Tile quality problems: the quality of ceramic tiles is also one of the reasons for loosening, and the water absorption rate of ceramic tiles directly affects the firmness of pasting. The state stipulates that the water absorption rate of porcelain tiles is E, and the shrinkage and expansion rate of porcelain tiles is about 4*10-6.

3. Construction process problems: during the construction process, if the cement mortar of the cushion is too thick or the cement is added too much water, the paved tiles will fall; In addition, if it is a large-size tile, if the seam is too small, the thermal expansion and cold contraction will squeeze each other, which is easy to cause warping and cracking.

4. Problems in daily use: the water absorption rate of the inner tile is low, if the tile is not completely attached to the cement, it is subject to a large impact, such as trampling or the impact of hard objects, it is easy to cause the separation of the tile and the cement, and the bottom of the brick is hollow.

In view of these situations, if the overall separated area is relatively large, then it is still recommended to use tile adhesive and then re-bond, but if the area is still relatively small, it can be repaired locally.

Addendum: Wall tiles (referred to as wall tiles) are suitable for façade decoration of toilets, kitchens, and outdoor balconies. Wall tiles are an effective way to protect walls from water splashes.

They are not only used on walls, but also on the edge decoration of doors and windows. It is also an interesting decorative element. Used for decorative wall tiles at baseboards.

That is, it is beautiful and has a protective wall base, which is not easy to be dirty by shoes or tables, chairs and stools. Tiles for sinks and bathrooms should be beautiful, moisture-proof and wear-resistant.

When gluing tiles, there is no sufficient water immersion for more than half an hour, and the technique of sticking tiles is not good, I think this is the reason. Or it may be frozen, but the sticky tiles are also frozen and the pieces are falling, not the whole piece. To remedy the good silicone structural adhesive you bought, or silicone weather-resistant sealant adhesive, I have used this method, and the effect is good.

The reason is thermal expansion and cold contraction, and the remedy is re-stained with glue. If possible, when renovating later, it is good to let the house be fully ventilated.

The reason is very simple, everything has thermal expansion and cold contraction, and then there is no flexibility of cement can not withstand the external thermal expansion and cold contraction, cement in the bonding of the surface brick or to the surface brick when the water loss is too fast to cause insufficient strength, etc., the remedy is, first, if the tile joint is separated, use waterproof mortar to coat a layer at the tile joint, if the brick falls off, you can also use waterproof mortar to coat a layer and then stick it, two, you can also use polymer mortar (and waterproof mortar properties). Third, if you can't buy the above materials, you can also use white latex or water-based latex paint (acrylic, styrene) based to adjust the properties of cement mortar, and fourth, if it is not very serious, you can use silicone weather-resistant sealant to apply a layer.

The cement is separated from the wall along with the tiles, and the common reasons are as follows:

1.The problem of cement base surface, the base surface of the tile is too smooth, so that the adhesion force with the wall is not strong.

2.If the cement river sand is used to paste tiles, then there may be a problem with the proportion of cement river sand.

3.The grade of the cement is too low, or the quality is questionable.

4.After the tile is pasted, there is no fixed support, and the tile falls off as a whole due to the action of gravity.

5.When the worker is constructing, the thickness of the mortar is too thick or too thin, and it is not evenly smeared, resulting in hollowing.

In view of this situation, if the overall separation area is relatively large, then it is still recommended to use tile adhesive and then re-bond, but if the area is still relatively small, it can be repaired locally.

？？How come??

This is a problem with the construction quality of the inlay, which can only be completely eradicated, treated with the base layer of the wall, and then re-inlayed.

If the wall is painted with waterproofing, the porcelain tile and the cement are separated from the wall together, what is the reason.

A few days ago, a few tiles suddenly fell from the house, but fortunately they didn't hit anyone, which scared me to death! There is no problem with looking very stable during acceptance, but when the wall tiles are removed, it is simply caused by not shoveling the wall skin. I can't find the person in charge of the renovation, where can I reason?

Look at this large area of white wall skin, how can the tiles be firmly pasted, and they can't be used for a long time! Therefore, you must remember to shovel the wall skin when sticking wall tiles, otherwise you will not be able to find anyone to reason with you.

I looked for a decorator again, and they said that they wanted to reinstall, because the area was too large, but now it was inconvenient to reinstall, so they temporarily used expansion screws to do a simple fix.

Here are a few reasons why wall tiles are used for a short time and are easy to fall off:

1. The quality of wall tiles.

The water absorption rate of wall tiles is directly related to the adhesion force, but it is not that the higher the water absorption, the better, if the moisture is not enough, it will be inconsistent with the cement shrinkage, which will lead to the falling off of the tiles.

2. The grassroots work has not been done well.

Underlying questions are often the most common. When we decorate a new house, we will shovel the wall skin, but most of us simply shovel or paint the wall. However, no matter how much the wall is brushed, if the wall skin is not cleaned, it will greatly affect the friction and adhesion of the wall.

Also, the wall is not watered enough, and the tiles are not cleaned properly, which will leave hidden dangers.

3. The tile is not dry and receives bumps.

When the cement mortar has not been completely bonded to the wall and is dry, it is best not to let it be collided, which will cause gaps in the mortar, resulting in unstable paste, and it may fall off in the future.

4. Gaps between tiles.

Gaps need to be reserved between wall tiles, because the effect of thermal expansion and cold contraction will cause them to squeeze each other, resulting in fracture or falling off. The cement mortar behind the wall tiles should not be too thick, which will not only affect the overall effect of the space, but also the thermal expansion and contraction will be very unstable, which will accelerate the falling off of the tiles.

After one year of renovation, the tile butt gap on the edge of the pillar in the bathroom falls off, which is a bonding problem and has nothing to do with the quality of the tile. It needs to be re-pasted.

In such a situation, the wall tiles are not well bonded during the pasting process. There are two reasons for poor bonding: one is that the wall tiles are too wet or too dry when bonding; Second, the surface of the square column structure is not sand and plaster, and is made of cement board or GRC cement - which is not conducive to tile bonding.

If it is repaired, it is necessary to remove the old wall tiles and sand and gray base: if it is a sand and gray base, the bricks should be wet, controlled and dried, and then pasted; If it is a column made of cement board, use high-quality structural adhesive to paste the wall tiles.

It is a construction quality problem.

The reason is that when the tile is paved, the cement mortar is unevenly applied or the cement mortar is delaminated from the base layer, resulting in hollowing. According to the provisions of the national "Housing Construction Engineering Quality Assurance and Warranty Measures", the decoration construction party of the decoration project of ceramic tile paving shall provide a decoration warranty of not less than 2 years, and the construction party can be contacted for maintenance.

It is suggested that it can be dealt with according to the following methods: first check the tile with cracks at the sunny corner, if the tile is firmly bonded with the base layer, you can use glass glue to paste a L-shaped male angle line at the sunny corner; If the tiles in the cracks of the gaps are loose, it is recommended to remove the tiles at the sunny corners and re-subsidize the tiles.

Dig the best permeable waterproofing can be done by yourself.

If the cement surface is to be waterproofed, use the super permeable waterproof guard of digging excellent black gold steel to do waterproofing (if there are cracks, gaps and potholes on the cement surface, fill the complete with digging beautiful butadiene glue and then do waterproofing).

For the tile surface, first check whether the filling of the tile gap is complete (if the filling of the tile gap is incomplete, fill it with dug beautiful butadelon glue, and then use the black gold steel stone tile type to do waterproofing).

Hello, there are many reasons for the blackening of ceramic tiles, in addition to the difference in the origin of the embryonic body, the density of the product itself is not enough, the firing time and temperature, process, machine, production line, etc. are not up to the standard and so on. In short, all kinds of links are not up to par, and they are all caused by quality.

It is recommended to pay attention to maintenance and cleanliness at all times.

Solution:1Use tungsten steel rods to clean the gaps in the tiles.

2.Slapping sewing agent.

3.Flattening with your fingers dipped in water.

Clean up the remaining material after curing.

Mix hydrochloric acid or phosphoric acid solution with water in a ratio of 1:5, spray the mixed water on it (you can also bring rubber gloves and wipe with a rag dipped in water), and wipe it several times. Cleaning and maintenance of ceramic tiles:

1. The ordinary dust on the surface of the tile can be cleaned with dish soap, soap, laundry detergent, etc.

2. The wax layer of polished bricks when leaving the factory can be removed with decontamination king.

3. The cement scale, caulk and other dirt remaining on the surface of the tile can be removed with the descaling king.

4. Paints, coatings and other pollutants are dissolved and removed by chemical solvents, such as Tianna water.

5. Black metal scratches, welding marks, etc. can be removed with descaling king.

There is no way to deal with the phenomenon of black and decolorization of floor tiles and ceramics, like what polishing and waxing treatment is talking about stone, not ceramics. The marble can be renovated, polished and waxed. Ceramics can't do it.

Because the principle of ceramic floor tiles is only the surface, not the same material from the inside to the outside. Same pattern. Gujia marble is the same material and pattern inside and out.

Therefore, it can be refurbished, polished and waxed. The surface of the floor tiles will be worn, after the glaze layer on the surface is worn off, plus the bricks you buy should have quality problems, if the quality is passable, more than ten years is not a problem. It won't happen in five or six years.

What you see now is blackening, which is caused by the cement mortar layer that penetrates from the back of the brick to the surface. So it's dark to see, so it's impossible for you to be like new, and you can't renovate bricks.

What nonsense! Also back penetration.

There are two ways to do this:

The first type: 1. Clean the old cement in the place where the tiles fall off.

2. Soak the tiles for a few minutes, and then soak the cement to the same extent as soybean oil.

3. Take out the tiles and dry the water on the surface, and then evenly coat the cement on the tiles (the thickness is about the same as the original cement slurry).

4. Just knock it flat with wood.

Once the wall tiles fall off, the first thing to check is the cause. Normally, if the cement mortar layer of the fallen wall tiles is strong with the wall, then the loose wall tiles around it are also lifted down and repaired together with the original fallen bricks. According to the peeling area, a bucket of 903 glue, a kilogram of white cement and some wall tiles of the same color and specification are purchased for repair.

It is advisable to hire a professional bricklayer, but if the amount of work is relatively small, it is often relatively expensive. In addition, it is necessary to master some paving methods to better grasp the quality of the project. Tiling generally adopts the five-point pasting method, that is, the four corners of the brick and the center of the brick are smeared with 903 glue, the brick order is from bottom to top, the gap between the bricks and the bricks should not be less than millimeters, and the last row of bricks should not be hard plugged, and the edge should be ground with a grinding wheel to ensure that the gaps are uniform and consistent.

When the bricks are pasted, you should also pay attention to the cleaning of the wall tiles. Use white cement to hook the joint, the jointed cement can be held into a ball by hand, use a tool to press the cement into the joint between the bricks and bricks, and finally wipe the brick surface with a rag, and the brick repair process is completed. This method of repairing bricks, saving labor and time, can be completed in one or two hours, and it is completely possible for skilled people to do it themselves.

The second type: 1. Wash the mortar on the back of the tile and put it in a cool place to dry.

2. Smash a small pit on the adhesive mortar (that is, the cement mortar on the wall) of each tile, with 2 points at the top, middle and bottom, with a size of 20mm and a depth of about 5mm. Clean up the dust, loose cement slurry, etc. in the pit.

3. Fill the part of the small pit with a high glue (stone glue) about 2mm higher, be careful not to fill it too full. Exam Forum.

4. Paste the peeling tile back before the glue solidifies, and gently tap it with a small hammer until it is flat with other bricks.

Note: The gel must be used with the mixture, and the amount of coagulant should not be too much, otherwise the solidification will be too fast, and too little will be slow to solidify.

This method bonds strongly and there is no elevation difference on the surface.
