How to deal with the alkali of the indoor wall, and how to solve the alkali of the wall

Clean the walls thoroughly and open the windows for ventilation.

The anti-alkali of the wall is mainly the result of the joint action of the two reasons that the water absorption rate of the exterior wall material is too high and the alkali content of the cement in the paste is too large, the crystals of natural stone are relatively coarse, there are many capillaries that cannot be seen by the naked eye, and the water carries water-soluble chemicals that can be immersed into the stone through the capillary tubes in the stone.

The fundamental cause of the alkali flooding of the wall and its decorative surface is the failure of the moisture-proof layer of the wall or the absence of the moisture-proof layer at all. As the moisture barrier fails, moisture from the ground rises along the capillary channels in the wall and evaporates from the surface of the wall.

The soluble salt and alkali in the soil and the wall will be dissolved into the water, when the water evaporates, the dissolved salt and alkali will crystallize and precipitate on the surface of the wall and near the surface, and its volume will expand slightly when crystallization, so it will form crystalline expansion stress on the surface of the wall and near the surface.

In daily life, the blank or the wall that has been decorated, but it will be alkali after a long time, the putty layer will peel off and fall off, and the layer of frost inside is very annoying. Shovel off the putty or return to alkali, oxalic acid does not work at all, so is there a better way to control panthene? The decoration industry, often encountering this situation, combined with work, talk about the solution of such problems!

Tools Raw materials.

Alkali elimination No. 1 group.

Wire brushes, paint brushes, blades, gloves.

Method steps.

Clean the walls thoroughly. Use a shovel blade to shovel off all the peeled putty, and shovel away all the putty that can be loosened; Use a wire brush to brush off all the alkali scale and floating ash on the surface;

Pour the No. 1 AB group together, stir well, and then brush it onto the cleaned wall, and use your wrist force when brushing to ensure that there is no gap;

24 hours, scrape putty, white leveling, and then brush latex paint or wallpaper, and there will be no more alkali.

end precautions.

If there is an obvious watermark on the wall and it is not dry, please brush the waterproof material (K11 or JS) on the outside of the No. 1 alkali elimination coating and then scrape the putty.

Ordinary concrete is silicate, when exposed to air or water vapor in the wall, hydration reaction occurs to produce hydroxide (chemical property is alkaline), when the temperature rises, water vapor evaporates, and hydroxide is brought out of the wall, with the gradual evaporation of water, hydroxide is precipitated from the concrete cement surface. In particular, the backwater walls of bathrooms and kitchens are the most susceptible to flooding.

There is a kind of wall solid treasure here in Chongqing, and the effect is good. It seems to be a product of Chongqing Fumao Technology Company, and it sells well in the Chongqing market. Products specially developed for wall problems such as wall alkali, sand rubbing and sand dropping.

Roll the brush directly onto the sand rubbing once or twice, and the effect is better twice. In particular, the kitchen and bathroom are full of rolling brushes, and other living rooms can be brushed meters high.

How to properly deal with the alkali on the wall, oxalic acid brushes the wall to neutralize the alkaline wall to achieve the most ideal effect!

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 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.

<> treatment method of alkali formation on indoor wall is as follows:

Completely remove alkali from the walls.

Use a brush to clean the walls.

Apply an anti-alkali agent to the area where the alkali is formed.

After the anti-alkali agent is dry and dissipated, just re-apply the gypsum Dazhou Bird Royal White.

If the above methods do not solve the problem, it is best to contact a professional repair company. They can provide you with professional technical support.

How to deal with the alkali wall: first remove the cement mortar powder layer of the wall, and then knock out the cracks of the wall skin after drying, use fine cracked Changshi concrete pouring, keep it for 3 days and then reuse the cement mortar with the guarantee of the number for powder layer treatment, if this still does not work, it is best to find the developer to ask it to treat the waterproofing of the outer surface of the building.

This case is applicable to most of the pan-alkali wall treatment methods.

Alkali formation of indoor walls is a very common phenomenon, which is caused by damp walls, insufficient sunlight exposure or improper maintenance during construction. This can lead to mold, blistering, and even peeling of the wall. Some new houses may also have similar problems, mainly due to not drying sufficiently after renovation, causing moisture to accumulate inside the walls, causing alkalization.

So, how to deal with the problem of alkali formation on indoor walls? Let me introduce you to several effective solutions.

1.Wash the walls.

First of all, the wall needs to be cleaned to remove dirt and paint from the surface for subsequent treatment steps. You can use a sponge and soapy water to wash the ambush, or use a wall cleaner. Be careful not to over-moisten the wall, so as not to exacerbate the alkalinization of the wall with residual moisture.

2.Neutralizes alkaline substances.

The next step is to neutralize the alkaline material on the surface of the wall to prevent it from causing further damage to the wall. Neutralization can be done using vinegar, lemon juice, or a specialized neutralizer. Vinegar and lemon juice will produce acidity in the reaction, neutralizing the alkaline substances on the wall, but then the wall needs to be thoroughly cleaned with clean water to prevent the acidic material from being left behind and causing damage to the wall.

The neutralizer is specially designed to deal with the alkalizing problem of indoor walls, and can be used in accordance with the requirements of the manual.

3.Moisture-proof treatment.

One of the main causes of alkali formation on walls is dampness, so the room needs to be kept dry. Indoor humidity can be reduced by using a dehumidifier or opening windows for ventilation. In addition, a waterproofing layer can be installed inside the wall to prevent moisture from penetrating into the wall.

4.Paint the old hall liquid anti-alkali paint.

Finally, applying anti-alkali paint is an effective way to prevent the wall from alkalizing again. Anti-alkali coatings have the effect of neutralizing alkaline substances, inhibiting moisture and preventing wall penetration. Before applying the anti-alkali paint, the wall must be cleaned thoroughly and the wall must be allowed to dry before painting.

In short, dealing with the problem of alkali formation on indoor walls requires a variety of measures, from cleaning, neutralizing, moisture-proof to applying anti-alkali paint, the steps are more cumbersome. For serious wall alkalinization problems, it is best to ask a professional decoration company to deal with it.

Now most of the home decoration is used Portland concrete, after a period of time the wall will be bulging, peeling or peeling, this phenomenon is called the pan alkali phenomenon. This phenomenon will not fade for a long time, which greatly affects the aesthetics of the wall. SoHow to deal with the alkali on the wallThis?

1. How to deal with the alkali on the wall.

1.The epidermal layer of the inner wall is the cement plaster layer, the putty layer and the topcoat layer, from the inside to the outside, the key part of the alkali resistance and alkali removal work of the wall is the cement plaster layer and putty layer. Alkali Resistant No. 1 is a direct fusion of the alkali content on the surface of the cement slurry layer, especially by using a combination of a high-efficiency alkaline cleaning fluid and an insulating layer, and the capillary pores of the cementitious layer are riveted.

Forms a strong protective film. At the same time, the use of high-efficiency, alkali-resistant insulation for double insurance, can effectively prevent and eliminate the problem of alkali flooding, yellowing and whitening on the wall. The elimination of alkali and the anti-alkali effect are stable.

2.Clean the walls thoroughly. Use a spatula to remove any loose peeled putty.

Use a wire brush to remove all alkaline limescale and suspended solids from the surface. Alkaline remover AB groups are poured together, stirred well, brushed over the walls with a brush, and apply pressure on the wrist to ensure that there are no gaps.

3.Waterproof walls, joints, boards, etc. as soon as possible to prevent moisture from continuing to penetrate and further expand the alkalinity of the fan.

4.Stone cleaner, a colorless translucent liquid made of nonionic surfactants, solvents, etc., can be used in commercial stone cleaners. But before using it, create a small test block to see the effects and decide whether to use them or not.

Second, the cause of alkali on the wall.

1.The joints of the exterior walls are built with fine cement mortar, which reduces the waterproofing effect. Groundwater (or wet water) invades the slate along the wall or mortar layer.

Ca(OH)2 and other salts are plated and dissolved in the capillaries of the stone to form alkaloids. It can be seen that water is the solvent and carrier of the stuffy acid material.

2.The fundamental cause of alkaline walls and decorative surfaces is that the moisture barrier of the wall is cracked or there is no moisture barrier at all. Due to the destruction of the vapor barrier layer of the wall, the water under the ground rises along the capillary channels of the wall and evaporates from the wall.

When the salts and alkalis dissolved in the soil and walls are dissolved in water and the water evaporates, the dissolved salts and alkalis crystallize near the walls and surfaces, and during crystallization, the volume increases slightly, so crystal expansion stresses are formed on the surface of the body and near the surface.

3.Alkaline alkali: The use of highly alkaline cement for coating film is because the alkalinity of the substrate is too high, and the alkali is a saline-alkaline matrix or putty with poor quality.

Sealing primers have poor sealing properties and are not resistant to water and alkalis. Too much water accumulates inside the walls and escapes from the outer wall surfaces. The ability of exterior wall paint to resist rainwater infiltration is relatively weak, a large amount of rainwater infiltration, and the water vapor after rain evaporates outward, causing the wall skin to fall off.

The above is a detailed introduction to how to deal with wall alkali and the reasons for wall alkali. It is recommended that if the wall is alkaline, you should take corresponding treatment measures and do not leave it alone. If.
