Is there any way to prevent the external wall tiles from always returning alkali?

The first method is to do the centralized drainage treatment of rainwater, you can lay a pipe, so that the rainwater flows out through here, and the second method is to make beautiful joints for the tiles of the exterior wall to prevent rainwater from entering the wall and not returning to alkali.

During wall construction, when the cement mortar is mixed, a certain amount of preparation can be added. For example, the water reducer effectively reduces the water content of the mortar. Improving the pit permeability of the wall can prevent the later return of the tile to alkali.

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, so that the water content of the mortar can be effectively reduced, and the impermeability of the wall can be improved to prevent the later tile alkali return.

If the wall tiles are alkaline, there will be some white things, which will be very unsightly. It can be rinsed with water, and oxalic acid solution can be used to paint wall tiles.

After the wall tiles are used for a long time, there may be a phenomenon of anti-alkali, and there will be some white things on the wall tiles, which need to be cleaned up in time. It can be cleaned with water, which is the case with the wall tiles in my bathroom, so I wash them repeatedly with water. After cleaning a few times, the phenomenon of anti-alkali of wall tiles disappears, because the bathroom floor is very wet, and it often washes clothes and baths, so it will lead to anti-alkali phenomenon.

Therefore, every time I use the bathroom, I turn on the ventilation fan for a while and open the door to release the humid air. During the construction, the wall is uneven, and the caulking of the tiles is not done, so this anti-alkali phenomenon will occur, so remind everyone that you must find an experienced master when decorating.

The wall surface is alkali-resistant, which can be removed by acid-base neutralization. Experienced masters usually use oxalic acid solution, then use some warm water, and use a brush to repeatedly brush on the anti-alkali position. This method can effectively remove the phenomenon of alkali reflux, and it is necessary to be patient when operating, to brush these solutions repeatedly with a brush, and to wear gloves when operating.

Because oxalic acid solution can injure**, it is necessary to wear gloves for handling. When there is an anti-alkali phenomenon on the wall tiles, it will affect the appearance, it must be found in time and dealt with in time, usually in the bathroom is prone to anti-alkali phenomenon, the environment of the bathroom is relatively humid, and water seeps into the gaps of the tiles.

Clean the wall in time, such as the wall of the bathroom, be sure to dry it after each use, and at the same time ventilate frequently to keep the wall of the bathroom dry, which will avoid the occurrence of wall alkali. If it is because of the anti-alkali caused by the permeability of the exterior wall, it is necessary to do a good job of insulation and waterproofing on the exterior wall. If the wall is alkaline, the white ash should be removed, then brushed with some white vinegar, and finally re-painted with a large white brush.

If it is caused by moisture return, it is necessary to paste the wall panel, so as to avoid the anti-alkali of the wall tiles.

In this case, oxalic acid solution can be added to warm water, the appropriate proportion should be selected, and then applied to the anti-alkali place to achieve the effect of removal; It can also be rinsed directly with water and then wiped clean with a dry towel, which can be dried in a dryer.

You can do a sanding of the wall and then repaint the wall. You can keep the wall dry, you can apply some separator on the wall, you can also apply cement paste to the wall, you can also sandwork the wall with sandpaper, and you can also control the water source in the house.

Redecorate. Lay a layer of cement on top of the wall tiles. Cover with waterproof material and polyethylene material. Rinse with water and add oxalic acid solution with water

Dear, I am glad to serve you, the answer is as follows: how to deal with the anti-alkali of exterior wall tiles? Answer: The answer is as follows: 1. The principle of acid and alkali neutralization can be used to use weak acidic substances, such as oxalic acid, mixed with warm water to form a certain proportion to remove the alkaline substances on the surface of the poor celery tile. It should be noted that when using oxalic acid, you should not let the oxalic acid directly touch your own **.

2. Direct rinsing with water is also a very effective method, but jujube needs to be cleaned many times until there is no more alkaline substance on the surface of the tile.

Alkali return to the brick wall, commonly known as "white psoriasis", refers to the phenomenon of white powdery or water-stained substances appearing on the surface of the bricks and tiles of the new wall, resulting in water loss, cracking, falling off and mildew of the wall, which not only affects the appearance, but also has an impact on the safety of the house structure.

There are many reasons for the return of alkali tourism on tiled walls, and a few of the main factors are listed below:

1.During the construction of the building, the wall surface was not properly treated, and there were substances such as ash, oxides, and carbides on the surface of the wall, and the wall could not be removed by sufficient clean water washing, resulting in alkali return to the brick wall.

2.In the construction process of the surface of the building wall, the electrolyte content of the water material used is too high, and the improper use leads to the lack of attachment substances on the surface of the wall, resulting in defects, and the moisture is easy to penetrate into the wall and cause the phenomenon of alkali return.

3.Under the influence of natural conditions such as ultraviolet rays, wind, rain, etc., the surface of the wall tile is oxidized, and the surface undergoes a small reaction, breaks, and continues to absorb moisture, causing alkali return.

4.Improper construction methods in the construction process, such as the use of different materials in the contact between the ground and the wall, make the air moisture content too large, which causes the wall tiles to fall off and the wall to alkali return.

In view of the above problems, we should take some measures to avoid alkali return on the surface of the building wall.

1.In the construction process of the building, the treatment of the wall surface should be strengthened, and the base layer of the wall surface should be laid, and the presence of ash, oxides, carbides and other substances should be avoided as much as possible.

2.In the selection of water materials, the electrolyte content must be strictly controlled, the control is fair, and the best water materials must be selected to avoid the improper use of water materials that lead to the lack of attachments on the surface of the wall and the defects.

3.In the construction of the wall surface, it is necessary to pay attention to avoid the influence of natural conditions such as ultraviolet rays, wind, rain and so on, and at the same time dry to reduce the occurrence of alkali return on the wall.

4.In the contact treatment of the wall, attention should be paid to the problems of uniform contact and the same material, so as to ensure that the surface of the wall is not affected later.

Alkali return to the tiled wall is a common problem in construction engineering, and it is necessary to strictly control the selection of materials, construction sequence, and construction methods in the construction to prevent adverse effects. In construction projects, reasonable construction processes, strict quality management and perfect building structure design can effectively avoid this problem.

Summary. First, the construction is mixed with mortar king or laundry detergent, and some construction personnel will mix a certain amount of mortar king or washing powder into the cement in order to make the cement more "workable" when building walls or painting, so as to reduce labor intensity. As everyone knows, after the addition of these substances, the alkaline content in the cement will be significantly increased.

When the wall is damp or the air is humid, it is very easy to cause the alkaline substances in the cement to "deliquescent", once these alkaline substances are "deliquescent", they will form crystals and seep out of the wall, so that the wall surface appears "back to alkali" phenomenon.

First, the construction is mixed with mortar king or laundry pants powder, and some construction personnel will mix a certain amount of mortar king or laundry detergent into the cement in order to make the cement more "workable" when building walls or painting, so as to reduce labor intensity. As everyone knows, after the addition of these substances, the alkaline content in the cement will be significantly increased. The alkaline substance is easy to absorb moisture, when the wall is damp or the air is humid, it is easy to cause the alkaline substances in the cement to "deliquescent", once these alkaline substances are "deliquescent", they will form crystals and seep out of the wall, so that the wall appears "back to alkali" phenomenon.

The alkaline content of cement itself is too highThe main component of cement is silicate, such as calcium silicate, magnesium silicate, aluminum silicate, etc., which are imitation of alkaline substances. However, the "alkali content" of cement from different origins is different. If the "alkali content" of the locally produced cement is high, then, when the wall is damp or the air is humid, the alkaline substances in the cement will be rapidly "deliquescent", resulting in the peeling and peeling of the stucco layer or the seepage of white crystals from the gap between the tiles and the tiles.

The interior walls should be tiled with cement, which is normal and penetrates into the back of the back.

1.The principle of acid-base neutralization can be used to mix weakly acidic substances, such as oxalic acid, with warm water to form a certain proportion of alkali and remove the surface of the tile. It should be noted that when using oxalic acid, the grass is not allowed to directly contact your **.

Cleaning directly with water is also a very effective method, but it is necessary to wash it several times until there is no alkaline substance on the surface of the tile. Stop it. Clean the alkali-proof area with a brush so as not to expand the alkali-proof area.

Then use a brush to dip an anti-alkali cleaner such as oxalic acid and apply evenly.

2.Let it sit for a long time, and after it is completely dry, then find a clean brush to brush white latex, putty and other materials on the wall. Finally, spray with a professional water repellent.

If you use a brush to clean too slowly, you can use a shovel to remove the wall skin that has returned to alkali and clean it up. After the operation is completed, stir the white vinegar and water in a ratio of 1:1, then dip the mixture with a soft cloth and apply it to the wall.

After two or three hours, the alkaline component will be removed. After the water is completely dry, finally apply polyurethane waterproof paint to the wall and let it stand for ventilation to dry.

3.The reason for the alkalization of the wall is that the waterproofing is a hidden project, and many people do not pay attention to it when decorating. For example, the water in the bathroom seeps out along the door, which will cause the wall to alkalize for a long time, so check whether the waterproofing is good before treatment.

The humidity of the walls is not allowed. If the moisture of the wall itself cannot be dissipated, the putty powder latex paint will cause too much moisture inside the wall during the later decoration, resulting in the long-term "alkali return" phenomenon of the wall. The objective causes of climate are thermal expansion and cold contraction.

4.Tiles laid on the wall are subject to intense cold shrinkage at temperature. If the tiles leave some cracks, there will be no warping or hollowing.

Even if the previous construction is better, if the wall is wet and exposed to water in the later stage, then the wall may be alkali resistant; Choose decorative materials such as low-alkali cement. By choosing a decorative material, we can choose a material with a low alkali content, which prevents the walls from being alkaline-resistant. The construction should meet the standard construction, and the wall decoration materials should be scraped several times.

After the first thorough drying, a second scraping can be made. Brush the alkali on the wall, being careful not to leave gaps;

In the case of strong relief, the relieved part should be removed and cleaned before scraping the putty again, and then applying a waterproof layer after drying; The trick in this situation is to remove the area with a shovel, and after the surrounding area is also removed, use some professional things to clean the damaged wall, and repaint the wall powder, and then make moisture-proof and waterproof paint.

You can use the principle of acid-base neutralization to solve such a situation, or let it stand for half a day, and you can also use the corresponding materials to solve such a situation. Be sure to do a good job of waterproofing, or use tile antifouling agent, you can also use paint, or use stickers to deal with it, you can also apply waterproof paint, which can solve such a situation.

It can be synthesized with weakly acidic substances, for example, after oxalic acid is mixed with warm water, the alkali on the surface of the tile can be removed, or you can buy some anti-alkali cleaners online, evenly spread on the wall, let it dry thoroughly for half a day, and finally brush it with white latex, and finally brush it with polyurethane waterproof paint, dry it, or replace the wall tiles directly.

In such a situation, it must be dealt with in a timely manner, and then it should also be re-made with the beauty sewing agent, keeping the contact area under the floor tile in a dry state, and after doing the beauty sewing, it is necessary to keep the indoor ventilation for a long time, so as to solve the problem of anti-alkali wall tiles.

The wall tiles can be replaced, so that the problem of anti-alkali can be solved. A better technique is that you can directly replace the wall tiles, you can carry out moisture-proof treatment or waterproof treatment on the wall tiles, you can also pour some water on the wall tiles, and you can also soak them when you paste the wall tiles.

Wall tile anti-alkali refers to the phenomenon of "frosting" on the wall brick, which is generally due to the alkalinity of the limestone or sand used in the construction of the house, the wall or the adhesive used to pave the tile, of course, if the wall is seriously damp, the wall surface of the water seepage part is not treated in time, and the wall tile anti-alkali situation will occur in the long run. If there is a situation of anti-alkali of wall tiles, we can use glue or white vinegar to solve the situation of anti-alkali of wall tiles. Below I will briefly introduce what are the specific causes of anti-alkali of wall tiles, how to solve the situation of anti-alkali of wall tiles, and how to avoid the situation of anti-alkali of wall tiles

What are the specific reasons for the anti-alkali of wall tiles?

There are basically two reasons for the anti-alkali of wall tiles, one is because the alkalinity of the binder used in the wall or paving tiles is too heavy, and in the process of cement drying, the alkali cannot evaporate with the evaporation of water, which is left on the surface to form a white alkali layer; One is that the indoor air is too humid, and the moisture in the house is very heavy in the case of rainy days for a long time.

How to solve the problem of anti-alkali wall tiles.

If it is caused by the alkalinity of the wall tile adhesive, then we can use white vinegar or oxalic acid mixed with water, pay attention to the water temperature requirement of about 60, and then brush the oxalic acid solution or white vinegar water into the seam, fully neutralize the alkalinity in the seam, and then dry, then wash, and then dry, so repeat 2 to 3 times, dry it, and then we use special caulk or beauty sewing agent to carry out beautiful seams; If it is because the wall is too wet and causes the alkali, we need to treat the wall, we need to shovel off the original wall skin, and then use a steel wool ball to brush it clean, pay attention to the cleaning range is larger than the original alkali, and then mix the alkali elimination No. 1 AB group evenly, and paint the alkali on the wall, after standing for 24 hours, you can continue to scrape putty, leveling, and finally you can paint latex paint or wallpaper wall cloth normally.

How to avoid the situation of anti-alkali of wall tiles.

If we want to avoid the situation of anti-alkali of wall tiles, then we need to pay attention to the indoor air to ensure dryness, the roof wall to do a good job of waterproofing, and to pay attention not to use anti-alkaline wall tile adhesives, so as to ensure that our house will not have anti-alkali wall tiles.
