How to deal with the alkali peeling of the wall, and how to deal with the alkali peeling of the wall

Scrape the peeling wall and repaint it, and the house needs to be ventilated more, and the alkali is returned because the house is too damp.

The question you asked is a headache, my house is a new house, built only four years, renovated last year, this year the wall has been alkaline, I know that the wall is damp to become like this, even if it is scraped again, it will be alkaline.

Completely remove the alkali return on the wall to expose the brick wall, then re-smear the cement, and scrape the latex paint after drying.

Clean the place where the wall returns to alkali, re-apply putty, open the window in the house for ventilation, and dry it.

In the case of alkali peeling on the wall, the wall plastering layer can only be removed or scraped off, re-plastered, and the wall paint (or decorative materials) can be re-made. If you don't want to do this, then directly use a brush to sweep off the peel of the wall surface, and re-paint only on the original wall (wall latex paint), but the paint should be lightly brushed, quickly brushed, and brushed back and forth to minimize repeated brushing. Wait for the previous paint to dry thoroughly before brushing the second (multiple) time, so as not to stick to the paint of the previous brush.

This treatment method is simple, fast, and low-cost, but the flatness of the wall is poor after treatment.

Let's talk about the reason for the anti-alkali on the wall first, the anti-alkali of the wall is generally accompanied by the damp place of the wall. In particular, the back is a kitchen wall, or a bathroom is prone to such a situation. There are two kinds of wall peeling, one is anti-alkali peeling, the main feature is that the wall has obvious white ash.

There is also a kind of water peeling on the wall, and there will be mold for a while, and there is no white ash. The reasons for peeling are different, and the treatment methods are also different. The main reason for the anti-alkali peeling is that some chemical changes occur between the cement and the air, and the water and white ash are produced after the chemical reaction, and the water evaporates, and the white ash adheres to the wall.

The correct way to deal with it is to clean up the latex paint base of the anti-alkali wall, that is, to clean up the white ash and leak out the gray and black cement wall of the wall, and it is best to clean up the scope of a larger one.

Then, get a little alkali solution to clean the wall, it is really rare to buy, you can go to the hardware store to buy some oxalic acid, anyway, it is acid and alkali neutralization. Eliminate the alkali that does not come out.

Then, it is best to do a layer of waterproofing on the wall, just the kind of liquid, liquid waterproof, brushing on the wall is a very powerful protective film, this protective film effectively prevents the air from entering the wall, the air can not enter the wall, the cement will not undergo chemical reaction, and it will not be anti-alkali.

Liquid waterproof is best brushed twice, horizontally and vertically once, to the first time almost dry in the second brush, very simple. Generally, it takes about a day to dry with waterproofing. After drying, put plaster, putty, in the sanding, in the latex paint.

In such a situation, it is recommended that you shovel off the wall skin by yourself, clean it with a reduction solution, and brush the waterproof by yourself. After the waterproof is dry, the paint on the surface is repaired on top of the latex paint master, and it is best to take a blow dryer. If you do this, the painter will be done in one day, so the painter will charge a little salary at most, and the front brush waterproof is also a rare experience for you, and it is very simple.

It can only be cleaned up of the latex paint base layer of the anti-alkali wall, which is to clean up the white ash.

1. The first treatment method should be to clean the surface of the wall, which can be combined with the surface pollution and acid rain reaction of the material in the process of use, and use a certain proportion of oxalic acid solution for regular cleaning.

2. It is necessary to purchase surface materials with high density and cement materials with low alkalinity, and then adopt the dry hanging construction process to avoid wet paste, and finally do waterproof treatment, paint waterproof materials on the concrete or cement plastering base, and then paste the construction with non-alkaline adhesives.

It should be that the walls of the house are protected from moisture, and the walls of the house are ventilated frequently to ensure that they are dry and redone.

Putty on top, then re-apply latex paint, a few more brushes.

It is possible to remove all the original wall skin and repaint it.

It is usually accompanied by a damp place on the wall to see if there is a leak.

The best and most thorough way is to scrape off and re-brush with another material.

After you clean it, you're shaving it all over again, and you're good to go.

Get rid of the skin that has returned to alkali, and find a professional master to re-shave it.

I don't think there's any problem with finding a professional white worker to brush it for you anew.

1. Grassroots treatment. Use a shovel to clean the peeled wall, expand the cleaning area to the surrounding area of the alkali part, and then rub it with a wire brush until it is completely flat, and then remove the pansoda on the surface of the mortar by cleaning the external surface.

2. Waterproof. The surface of the inner and outer layers of the mortar should be waterproofed to isolate the wall from the atmosphere and prevent the reaction of chemicals with water vapor.

3. Block slotting. If the wall is paved with tiles, it is necessary to use a tile cutter to cut a groove wider than 5mm around the alkali return part, which is to block the alkali return force after brushing the alkali resistance primer. In addition, the depth is as close as possible to the brick body, and the bottom junction does not need to be grooved to prevent spread.

Ways to prevent anti-alkali

1. The construction must be in accordance with the specifications. During construction, in order to avoid the alkali return phenomenon caused by the construction process not meeting the specifications, we must follow the specifications of the construction, do not rush. The wall upholstery needs to be scraped twice, and the second time must be done after the first coat is completely dry.

2. Waterproof engineering. Although the early construction is better, it will also cause moisture due to some reasons in the later stage, so the waterproof work must be in place.

3. Alkali cement and other decorative materials. Building materials are mostly alkaline, and the problem of alkalinity cannot be avoided, and when choosing decorative materials, you can choose materials with relatively low alkaline content.

Answer: How to deal with the phenomenon of alkali return and peeling on the wall, which is largely caused by the damp reversal, so we need to first remove all the putty layers on the wall that have peeled and alkalinized until the cement inside is exposed. Next, wait until it is dry, and then scrape the putty again, and after the putty is done, wait until it is dry, and then brush a layer of waterproof paint. 2.

How to repair wall cracks is also a common occurrence, we need to understand the causes of formation, such as cracks between insulation boards, or shrinkage caused by slotting in the wall.

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.

Relevant 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 relatively 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.

Depending on the situation, the specific handling method is as follows:

1. Drop the wall skin in a small area: the area is relatively small, and a certain wall appears a little, and the temporary solution is to put a calligraphy and painting to cover it. From the point of view of dealing with patching. Fall off the loose part of the surrounding area and dispose of it at the same time. Brush the same latex paint down and you're good to go.

2. Even the putty falls off: deal with the parts of the wall that fall off, and also split the putty first. After drying, lightly sanded with sandpaper. Then repaint the same paint.

How to repair the wall skin peeling off and alkali: 1. First of all, the wall to be decorated must be solid, firm and dry, and the moisture content is less than 10, and the old base must be cleaned up. Some developers in new houses use 821 putty when handing over the house, this putty is easy to powder, peeling, falling off, the problem is clear, if it is the use of 821 putty powder, it is recommended to shovel all out, re-base treatment.

2Secondly, before re-scraping the putty, the covering primer must be applied once. Applying a sealing primer can improve the pH of the base wall, increase the strength of the base layer, and make the coating more cohesive to the wall. When choosing a sealing primer, be sure to choose a special primer from a regular manufacturer, and don't replace it with some glue.

3. The last and most important step is to scrape the putty powder. Before applying latex paint, you need to scrape the putty twice. It is best to choose putty powder from a well-known brand.

The brand's putty has high whiteness, good water resistance, high bonding strength, no peeling, no chalking, and no falling off after use, which can solve the trouble of wall skin peeling.

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.

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.

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.
