What is the cause of alkali peeling of the inner wall below one meter? How to deal with it?

The inner wall is mainly due to the improper use of the adhesive inside, as long as you find a professional to repair it, it can be restored.

It's all caused by the moisture from below returning upwards. It should be treated on the interior walls. First of all, the putty layer and latex paint layer on the surface of the indoor wall are removed to reveal the plastering layer inside.

Paint the surface of the wall with cement-based permeable crystallization, and then restore the putty layer on the surface to restore the latex paint.

This situation is generally due to the failure to prevent moisture, and it may also be caused by water seepage. If you want to deal with it, you must choose a special alkali return treatment agent, first spray the wall, stand still for a period of time and then do a good job of the base, and then re-decorate.

1. If the alkali peeling of the wall is not serious, the wall can be washed with a concentration of 10% oxalic acid solution. 2. Clean the skin of the wall until it does not fall off, and the place that has been swollen or peeled should be cleaned with a shovel. 3. After grinding and smoothing the removed part, select the appropriate putty powder, mix it evenly according to the specified proportion, apply it to the wall, scrape a layer of putty again, wait for the putty to dry completely, and recoat the primer and topcoat.

Related knowledge popularization: 1. It is necessary to pay attention to the moisture-proof work during construction, and the general anti-white alkali may be caused by the high water absorption rate of the decoration materials, or the high alkali content of the cement in the paste. The waterproofing of the ground should also be done well.

Otherwise, the underground water gradually rises along the wall, and finally evaporates from the wall, which will also cause anti-white alkali. 2. Use river sand as much as possible, and avoid using sea sand, which has a high alkali content and is more likely to cause the phenomenon of anti-white alkali. 3. The humid climate will also cause the phenomenon of wall peeling and peeling, and sometimes there may be aging and leakage of pipes inside the wall, which will also lead to cracking and even peeling of the wall.

4. It is best to be eliminated in the early stage of construction, and each process must wait until the wall is completely dry before starting the next stage of the process.

You can clean the area where the skin has fallen due to alkali return, tear off the peeled wall, and then clean the wall. Then use a professional facet tool or spatula to clean the wall, and then use a variety of brushes to clean the wall. After some cleaning, the alkali elimination solution for the interior wall is used to eliminate the alkali of the wall skin caused by anti-alkali.

Only then can the alkaline substances stored in the wall be thoroughly cleaned and cleaned. Finally, after the reduction solution has solidified, use greasy Jingque Peizi and a series of scraping tools to smooth the wall.

1. The anti-alkali peeling may be due to the material composition of the wall skin, etc., due to the high salt content of the crystals in the wall skin material, the possibility of sucking out the crystals may be higher, if the salt content is relatively low, the crystallization situation should not appear.

2. If the living environment is humid or there is heavy rainfall around, the cooling weather will lead to bright and humid air, resulting in the precipitation of a large number of salt crystals.

3. The anti-alkali phenomenon of the wall The anti-alkali phenomenon that may occur on the north wall will be a little more than that of the south wall, because the north wall is in the backlight position, so the crystal precipitation is more.

4. Because the interior wall is indoors, the ventilation in a closed space is insufficient, which leads to the inability to carry out a good water vapor dredging effect on the wall, so the possibility of the anti-alkali phenomenon of the interior wall is relatively high.

Indoor latex paint peeling is a difficult problem in thousands of homes, mainly because of the dampness and coldness of the internal structure of the wall, resulting in a damage to the bottom layer of the wall paint. In a similar situation, whether the finishing material is wall paint or wallpaper, the wall covering will be affected. The alkali reaction on the edge of the window is generally mild, and the sealant at the connection point between the window and the wall is aging.

When it rains, the precipitation will leak into the room according to the area. At the same time, the quality or quality of aluminum alloy windows is not good.

Rain will descend down the rails along the windows, leaking water into the rooms at the 90-degree junctions of the windows close to the façade of the building. Therefore, it is necessary to check the window sealant on the outside of the window frequently. The anti-alkali peeling condition on a wall in the home is basically caused by dampness and cold.

One wall of the house is in a state of anti-alkali dampness and cold, which is very likely to be the partition wall in the middle of the bathroom and the large living room. The toilet requires a lot of water, and it is in a wet situation every day, and it is an indoor space that is used more frequently.

Due to the daily bathing, the water will gradually merge in the whole process, and there will be no immediate indoor ventilation, and over time, the walls will be alkalinized and other conditions will occur. The reason for the greater peeling of the wall is that the wall is damp, so the peeling wall will generally be close to the wall of the toilet and the kitchen of the restaurant.

The first step in solving the wall surface is to shovel off the wall surface that is heavily peeled until the bottom surface layer of the mortar is mixed. Then clean the bottom layer to make the base neat and level. The next step is to batch the putty, and after the putty powder is dried, it will be leveled.

Finally, the wall paint is painted, the wall paint is painted first, and the top paint is brushed twice after the top paint is dried. Shovel off the lime powder in the anti-alkali part of the room, clean it with white rice vinegar, brush a layer of waterproof putty, and touch it with your fingers to see that the powder is not easy to fall off. On the premise that there is no powder dropping, start the plaster putty to apply the wall paint normally.

How to deal with the alkali on the wall.

1. If there is bubbling and peeling on the wall, you can first remove the putty on the wall, then apply the interface agent to the wall, scrape the putty three times, and brush a layer of primer.

2. If you want hoarfrost to disappear and no longer appear, then when processing, you should pay attention to the temperature of the wall, if it is in spring and autumn, the natural drying time of the wall should be at least five days, and the natural drying time in summer should be about ten days.

3. If the wall repair area is relatively large, the wall treatment time will be longer. In short, to ensure the quality of the paint, install the painting process for treatment, and control the temperature, so that the problem of wall alkali can be solved.

What are the dangers of wall alkali.

1. If there is a pan alkali on the wall of the house, it will affect the decoration effect and beauty of the overall house, and affect the living environment and health of the family.

2. Generally, the wall alkali is integral, and the wall alkali problem must be renovated, so that the decoration cost of the house will rise significantly.

3. If there is serious alkali in the base layer of the wall, it will affect the film formation of the bottom coating, resulting in problems such as alkali on the wall and imperfect painting.

4. If the wall alkali causes corrosion of the wall substrate, it will affect the safe use and durability of the whole house.

If the alkali on the wall is very serious, it will lead to cracking of the wall skin and even affect the health of family members. It can be ventilated to dry and the putty can be scraped again.

It may cause the paint to be white, which will seriously affect the appearance, and there may be some corrosion, and it must be renovated.

1. The exterior wall is permeable, due to the developer's reasons for the foundation settlement to cause cracks in the wall, some walls will be permeable if there are no cracks, and the walls will definitely return to alkali if they are wet with water for a long time. Second, the room without a basement on the first floor is inevitably alkali returned by moisture, and there will be alkali return to more or less. Especially in the summer, before the sweltering rains, the whole floor is wet.

3. If there is a one-time water leak upstairs, no matter how bad it is, it will not return to alkali. Only long-term water leakage will cause alkali return. Fourth, the water supply pipe of the kitchen and toilet is broken and leaking, and it spreads to the corner of the bedroom wall of the dining room through the floor tile cushion, and it will definitely return to alkali for many years.

Fifth, the drainage problem of the bathroom, all residents who have not installed secondary drainage will encounter the phenomenon of the wall skin falling off and returning to alkali at the door of the bathroom. This phenomenon accounts for more than 80 percent. Sixth, in the summer when the wall is built, the refractory bricks are poured too much, the outside is plastered and the bricks are still wet, the surface of the large-area plastering wall is dry and water-collecting, and the inside is still wet, and there will be alkali white ash after a long time.

Seventh, the top floor Kai Roll leakage back to alkali, generally most of the top floor has water leakage, long-term water leakage will lead to the indoor wall skin peeling off and alkali back phenomenon.

After the house is renovated, it is not necessary to travel all kinds of problems, especially the walls. For example, wall cracking, mold, alkali, peeling, etc., these problems have a great impact on our lives, so we must deal with them as soon as possible. So, how to deal with the alkali peeling of the wall?

What is the reason for the alkali return of the wall? Let's take you to find out.

For this phenomenon, it is necessary to clean the anti-alkali peeling part of the wall first, remove the wall piece with a shovel, and then use a wire brush to smooth it. Then use the crack alkali to clean the wall, which can eliminate the remaining alkali in the wall, and after the wall alkali is completely solidified, then brush with putty powder and leveling. Finally, brush it with latex paint and you're good to go.

The cause of the alkali return of the wall.

1. The wall is damp.

The alkali return phenomenon will occur in the wall of some homes, which is basically caused by the fact that the wall is not dry enough and too wet when the putty is scraped. Therefore, in the later use process, there will be a phenomenon of alkali return. However, if there is alkali reflux on the wall in the bathroom, it is basically caused by excessive moisture inside.

2. The wall is damp.

Some houses will have poor ventilation, so it is easy to return alkali to the wall after a long time. Because of the poor ventilation of the house, the wall is easy to be eroded by moisture, and the phenomenon of alkali, decay and peeling will appear after a long time. Therefore, it is necessary to open more doors and windows to maintain indoor ventilation.

3. The alkali content of the wall.

The reason why the walls of some houses have alkali return is because the walls themselves contain a certain amount of alkalinity. For walls with too high alkali content, it will slowly reflect after a long time, resulting in peeling, mildew and rot on the wall. Therefore, during the renovation process, you must pay attention to this.

Article summary: The above is all about how to deal with the alkali peeling of the wall and what is the reason for the alkali return of the wall, I hope it will be helpful to you. If you want to know more about it, please stay tuned to Qeeka Home.

How to deal with the alkali peeling of the wall: 1. The alkali return of the wall is generally too much moisture, and there is alkaline substance in the cement at the bottom of the wall, and the base layer is closed after scraping the waterproof putty, and the water vapor can not seep out, forming an unbalanced state, resulting in the precipitation of alkaline substances and salts in the bottom layer. It is best to use a little oxalic acid solution to roll on the wall to fully neutralize the alkalinity of the wall, and then be sure to wait for the wall to dry thoroughly before brushing the primer topcoat, otherwise the wall paint will fall off in the future.

2. The wall peels off, the original wall is removed, a layer of waterproof gypsum board is laid on the wall, and then putty is scraped and latex paint is brushed. 3. First judge whether it is damp or the poor quality of its own substrate, generally you can buy a bucket of latex paint to paint again, if it is serious, in the case of economic prosperity, you can remove the substrate, scrape the putty twice, polish it once, and polish it twice, so that it will never fall ash.
