Oxalic acid or white vinegar is commonly used, and a watering can is used to eliminate the anti-alkali situation, and the effect is similar and not bad.

There are wall closure primers on the market, which are economical and have good results.

It should work, just try it.

This is the most expensive feeling I searched on the Internet.,The official announcement said that the invalid photo was refunded in full.,It is estimated that the effect can be.,Otherwise, don't install this.,It's a bit expensive 300 brushes 2 flat.,But it's really reassuring to be able to solve it.。

It works very well, the market response is very good, and it is worth a try.

Introduction to Alkali No. 1:

This product has a miraculous effect on resisting indoor wall alkali, and the operation is simple, low-cost, pollution-free environmental protection products, and has received unanimous praise from consumers.

Form characteristics: This product is milky white powder, non-toxic and tasteless, add water and stir to brush. The product has good alkali resistance, strong adhesion, and does not pan alkali after use. It can be widely used in indoor and outdoor walls, toilets, kitchens and other places that are easy to pan alkali, and it is inexpensive.

It has great advantages in terms of product effect and quality. It is the most ideal product for pre-decoration prevention and post-decoration treatment of pan alkali.

Product principle: After painting, a protective layer is formed to prevent alkali gas from escaping from the wall, and the purpose of alkali prevention is achieved. The unique organic acid particles in the protective layer will slowly neutralize the escaping alkali, so as to achieve the purpose of alkali elimination.

Precautions: When using this product, please operate strictly according to the instructions and do a good job of cleaning the wall.

For severe panalkali places, ** thick treatment.

If the wall is damp, the product will appear gray on the wall; Otherwise, it is milky white and has nothing to do with the effect of the product.

Shovel off the alkali turning part, brush the interface agent, and paint it. Either your alkali No. 1 is the interface agent, or it is acidic, and generally acidity is harmful to the human body.

At present, the best way is to use the alkali blocking brand treatment, the process is as follows the first step, remove the old coating, expose the cement base. The periphery of the affected area is grooved with a cutter to block the spread. The second step is to adjust the alkali card, mix and stir the two-component alkali card evenly, add a small amount of water for about 10 and then stir evenly.

The third step is to brush the alkali card twice, and brush it into it to fully soak the cement surface. The cut blocking groove should be brushed through the bottom to penetrate it. The interval between the two coats is 20 minutes.

The fourth step, after about 24 hours of drying, scrape two layers of alkali brand special matching putty powder. The fifth step is to polish and brush latex paint or primer. Step 6, Sticker or Topcoat.

The seventh step is to complete the delivery and acceptance. The above key is to do the first three steps well, and you can guarantee that there is no problem for ten years. The alkali barrier brand is a special product for the treatment of alkali return to the interior wall.

Hello, pan alkali refers to the appearance of salt-frost-like crystals on the wall, which can be formed for many reasons:

1. The substrate is a porous substrate, and there are alkalis and salts in the substrate, which will migrate to the surface of the coating film in the process of water volatilization, thereby destroying the coating film.

2. The sealing of the primer is poor, and the alkalinity of the substrate is too high, so the primer cannot be closed to the substrate, and the white substance that overflows moves out of the substrate and the coating film is neutralized to form a saline-alkali.

3. The humidity of the substrate is too large, and the moisture on the surface of the water seeps into the wall, and the water and moisture pass through the wall to bring the alkali out of the surface of the paint film.

4. The supporting primer is not used in the construction.

1. Remove the pan alkali layer, and carry out the construction of the coating when the moisture content of the wall is reduced to 12%;

2. If there is leakage, first carry out anti-seepage treatment;

3. Remove the old coating, paint the super-strong wall reinforcement, scrape the bottom leveling putty, scrape the surface layer putty, paint the professional primer, and finally paint the topcoat for construction.

Ordinary concrete is silicate, in case of air or water vapor in the wall, silicate ions undergo hydrolysis reaction, and the generated hydroxide combines with metal ions to form hydroxide with less solubility (chemical properties are alkaline), encountering the rise of temperature, water vapor evaporation, hydroxide precipitation from the wall, with the gradual evaporation of water, hydroxide is precipitated from the concrete cement surface, accumulating over time, so that the original decorative paint or paint and other things are jacked up, no longer adhere to the wall, whitening, peeling, shedding, a process called "panalkali".

Ubisculate in appearance:

Generally, Portland concrete used in home buildings or engineering buildings will appear like salt-frosted crystals on the wall after a period of time (the time can be long or short). The rough room will be directly precipitated, and the decorated, paint, etc. will bulge, peel and fall off. It does not fade for many years, which seriously affects the appearance, and this phenomenon is called the "pan alkali" phenomenon.

Causes. 1. The crystals of natural stone are relatively coarse, there are many capillaries that cannot be seen by the naked eye, the fine porosity of granite is the fine porosity of marble, its impermeability is not as good as that of ordinary cement mortar, the water absorption rate of granite is low, and the water can still be transmitted to the other side by the capillary immersion surface in the stone. This characteristic of natural stone and the existence of capillaries provide a channel for the infiltration and precipitation of water, alkali, salt and other substances in the adhesive material and the formation of pan alkali.

2. The binder material produces substances containing alkali, salt and other components. Mainly for the inlay mortar to precipitate Ca(OH)2 (calcium hydroxide) and follow the excess mixed water, along the capillary pores of the stone free invasion plate, the more mixed water, the more Ca(OH)2 moved to the surface of the mortar, after the water evaporates, Ca(OH)2 is stored in the plate.

Others, such as adding sodium Na+ admixtures in cement, clay brick soil containing Na+, Mg2+, K+, Ca2+, C1-, SO42-, C032-, etc., will penetrate into the stone pores and form "white flower" and other phenomena.

The alkali-containing and salt-containing substances produced by the binder material are the direct substances that penetrate into the pores of the stone to produce pan alkali.

3 Infiltration of water. The waterproofing effect is poor due to the use of cement fine mortar to hook the joints of the external walls; Ground water (or moisture) intrudes into the stone slab along the wall or mortar layer; During installation, the stone is sprinkled with too much water and other reasons, so that the water invades the stone slab, and dissolves into Ca(OH)2 and other salt substances into the stone capillary to form a pan alkali. It can be seen that water is the solvent and carrier of the panalkaline substance.

The principle of panuthinization.

Pan-alkali is the appearance of white traces on the wall, as if sweating, and if you deal with it, you generally need to remove the pan-alkali layer, and then repaint the wall.

In the decoration process, if the construction is not done well, it is easy to have all kinds of problems in the later use. Among them, the wall is alkali, which is a relatively common problem, and the owner is often at a loss when encountering this kind of situation. What are the causes and solutions of wall alkali?

Let's take a look!

The cause of alkali on the wall.

1.the walls themselves.

Generally, there are three layers on the wall, namely the base layer, the middle layer, and the surface layer, and the reason for the alkali return is often due to the solidification of these layers, resulting in poor adhesion, resulting in the problem that the wrapped particles are affected by external force and penetrate into the surface layer of the wall, and after drying.

2.wall coverings.

The use of bad wall materials leads to the non-bonding of the surface, and in case of bad weather, it is easy to cause the dampness of the wall, resulting in the problem of alkali return to the wall.

The solution to the alkali of the wall.

First of all, it is necessary to completely remove the surface layer of the area where the wall has returned to alkali until the base layer of the wall is visible. In the process of shoveling, the owner often finds that the surface layer has completely detached from adhesion. Then use oxalic acid with a certain concentration, add an appropriate amount of warm water for liquid preparation, and evenly apply it to the wall surface of the alkali return with a brush.

The chemical principle of acid-base neutralization reaction is used to solve the problem of alkali return on the wall. However, after the reaction is completed, rinse the wall surface from the alkali return to the alkali with water and wait for the wall to be clean. It is necessary to open the windows for ventilation and allow the wall to dry sufficiently, and then carry out the repair work of the wall.

How to prevent wall reflux.

1.Improves impermeability.

In the process of wall construction, when the cement mortar is stirred, a certain amount of preparation can be added, such as alkaline water agent is a good product. The water content of cement mortar can be effectively reduced, so as to reduce the porosity, change the size of the internal structure, and greatly improve the impermeability of the wall.

2.Strengthens moisture resistance.

In fact, it is to do a good job of moisture-proof measures on the wall, especially the corners of the wall, which are often the most important things that cannot be ignored. Waterproof paint can be applied to effectively avoid the penetration of moisture and reduce the alkali return rate of the wall. At the same time, try to choose materials with low alkaline content, which can effectively control the alkali content of the wall, but there are many reasons for the alkali return of the wall, and when it is solved, it needs to be dealt with in combination with the actual situation.

Hope the above, helpful.

Kiss! Hello, I'm glad to answer your <>

Wall alkali is caused by excessive unreacted calcium hydroxide in the wall material on the surface, or the improper use of materials in the construction is dissolved by moisture, resulting in wall alkali. To solve this problem, the following measures can be taken:1

Cleaning the wall: First, wash the wall with water to remove the dust and floating ash on the surface of the wall. 2.

Neutralization treatment: After the wall is alkalized, you can clean the wall with neutralizer and clean water, and the neutralizer should be added in strict accordance with the instructions for use. 3.

Moisturizing treatment: moisturizing, which can be sprayed on the wall with a variety of moisturizing coatings or polymer materials mixed with water, and the alkalinization reaction will be inhibited after the water is fully absorbed by the wall. 4.

Base treatment: For alkaline problems on the surface of concrete, manual grinding methods can be used to clean and grind the base layer, or special neutralizers and anti-alkali coatings can be used to treat the concrete surface. 5.

Use standardized materials and construction technology: to prevent the wall from being alkali again, qualified construction materials should be selected, and the process should be operated in accordance with the process specifications during the construction process to prevent the use of too much moisture and the construction is not in place. The treatment of wall pan alkali needs to be determined according to the actual situation and the specific characteristics of the material, but the above methods are common and effective wall pan alkali treatment methods.

I hope I can help you<>

Do you have any other questions?

In the spring and early autumn seasons in the south, it is easy to have a "return to the south", and it is very humid everywhere, resulting in the walls of the southern houses often have a situation of alkali. Now let's find outHow to deal with the alkali on the wallHow to deal with the alkali on the wall1. When decorating the wall of the house, the freshly plastered cement mortar wall should be watered for maintenance for more than a week, and then brushed with putty powder, paint, etc., so that the alkalinity of the wall can be reduced. Demolition.

How to deal with the alkali on the wall2. If the wall has begun to be alkalinized and the situation of alkali is more serious, the wall can be thoroughly cleaned first, and then the putty construction can be started after the wall is solidified.

How to deal with the alkali on the wall3. When painting putty on the wall, you must use weak alkaline putty, and you must not use strong alkaline putty, and after polishing the putty, you must apply an alkali-resistant primer.

What are the dangers of alkali on the wall:

1. If there is a phenomenon of alkali on the wall of the home, whether it is in the house or outside the house, it will affect the overall aesthetics of the house, and will also cause the paint on the wall to white, peel and fall off, and more seriously, it will destroy the living environment and quality of life of the home.

2. Usually the wall pan alkali is from the inside to the outside, and at the beginning it slowly affects the wall from the base layer of the wall, resulting in the reduction of the adhesion of the wall coating, resulting in the need for secondary treatment of the wall, which greatly increases the decoration cost of the house.

3. The alkali of the wall will affect the film-forming property of the putty in serious cases, so that the putty will lose its moisture early, especially for the strong alkaline putty, which will make the batch of putty scratch and scrape, and it is necessary to apply an alkali-resistant primer.

4. When the wall has a serious phenomenon of pan alkali, it will also increase the potential safety hazards of residents, especially for the outdoor wall, because the paint surface has a certain water resistance, if the paint film falls off, the moisture will migrate in the wall, which will have the effect of erosion and dissolution of the brick and mortar, resulting in the decline of the bearing capacity of the wall and increasing the unsafe factors of the house structure.

I conclude: That's what I shared aboutHow to deal with the alkali on the walland the full content of what are the dangers of wall flooding. The wall of the home will also lead to some other problems, because the place of the alkali will leak mold, and mold will cause certain harm to the body of the occupants, leading to diseases.
