What is wall alkali drainage? What is the way to remove the alkali on the wall

How to deal with the alkali on the wall thoroughly.

1. Clean the wall thoroughly, shovel all the peeling putty with a shovel, as long as all the loose ones are shoveled away, and use a wire brush to brush off all the alkali scale and floating ash on the surface.

2. Pour the No. 1 AB group together, stir well, and then brush it on the wall that has been cleaned.

3. After waiting for 24 hours, start to scrape putty, white leveling, and then brush latex paint or wallpaper, so that there will be no more alkali.

What is the cause of alkalinization on the wall?

1. If the wall is only on the surface of the alkali return, it is mostly caused by the poor compactness of the material inside the material and the easy absorption of water. When the material contains chemically unstable alkaline impurities, salts, such as carbonates, will be formed after acid rain, and white crystals will appear on the surface of the wall after the water evaporates.

2. If there is alkali on the wall, it is osmotic crystallization, which is mainly caused by the high water absorption rate of the exterior wall material. Some water-soluble chemicals will be immersed in the stone through the capillary tube in the stone, through the water as the carrier, the surface material micropores as the channel, the water, alkali, salt and other substances in the bonding material infiltrate and precipitate, after the water evaporates, the white saline-alkali crystals will stay on the surface of the stone, and the phenomenon of alkali return occurs.

Can the wall be alkalinized and can be attached to the wall tiles?

The reason for this situation is that the remaining moisture on the wall is not completely volatilized, if the situation is not serious, it can not be treated, once the situation is serious, it is recommended to remove the bottom ash, and wait until it is dried to re-apply the waterproof mortar.

Then the base surface is leveled and then the tile can be pasted, now the quality of the tile on the market is getting better and better, so the water absorption rate is constantly decreasing, the traditional cement river sand has been unable to meet the requirements of the tile tile, and the size of the tile is getting larger and larger, so it is more difficult to stick it, it is recommended to use professional knot materials, so that not only the adhesion force is strong, it is not easy to fall off the hollow drum, and the thickness of the knot is thin, environmentally friendly and non-toxic, and the aesthetics and firmness of the tile have a good guarantee.

The main reason for wall anti-alkali is that the cement product calcium hydroxide reacts with carbon dioxide in the atmosphere to generate calcium carbonate and deposit it on the surface of concrete products; Or in a solution of calcium hydroxide, a hydration product, when the water evaporates, the calcium hydroxide crystallizes in the cracks of the concrete and gathers on its surface. In addition, limestone or building sand contains a certain amount of soluble alkali-containing organic matter, and the hydroxide, carbonate or other alkali salt solutions formed by them can easily and quickly seep out "frost salts" on the concrete surface and frost.

How to deal with the surface anti-alkali.

1. Brush the alkali wall several times with a stiff brush (it must be dry brushed, washed with water or neutralized with acid is impossible to remove completely), and finally clean it.

2. The bottom of the first putty adopts the construction technology of exterior wall waterproof coating, that is, the construction white cement putty powder is mixed with JS waterproofing agent and then the bottom is laid.

3. The subsequent procedures can be carried out according to the normal coating construction process.

Everyone knows that the wall is painted a lot, but due to various reasons, it has alkali, in this case, we must use the right method to remove it, or it will not affect the overall effect. The following will introduce to you what methods are available to remove alkali from wall alkali.

If the situation is not serious, first grind off the hands of the person returning to the alkali ground, and then apply the interface agent, and start painting. But if the wall has begun to peel and bubble, it is necessary to remove the peeling and bubbling position first, and then you can apply the interface agent, scrape the putty three times, brush the primer once, brush the topcoat twice, and finally go through a week of maintenance period.

How to keep the wall paint in spikes.

1. Paint the wall and clean the general stains.

If you find that there are dirty marks on the walls of your home, you must wipe them off in time. For some water-resistant walls, you can use a cloth to scrub them, and after washing, you should use a towel to absorb the water and dry it, and for non-water-resistant walls, you can use an eraser.

2. Paint the wall for special stain cleaning.

For the stronger wall, you can use some fine sandpaper to gently grind it off, and then use some wall paint to repair it a little.

3. Treat the moldy phenomenon of the painted wall.

If it is wet and rainy, then some mildew spots are prone to appear near the toilet and kitchen, which will also affect the appearance of the wall. In this case, if it is a white wall, you can wipe it with bleach, which can not only effectively remove mildew, but also play a role in disinfection.

4. Crack treatment of painted wall.

If there is a crack in the paint, then you can directly shovel it off, you can use the same color to repair it, and then use sandpaper to polish it flat, which is also more aesthetically pleasing.

Summary: What is the method of alkali removal on the wall is introduced here, first grind it off the alkali return place, and then apply the interface agent before you can start painting. If you want to know more about related knowledge, you can consult Qijia.com.

What is the cause of alkali on the wall?This? Let's take a look.

What is the cause of alkali on the wall?-The walls are caused by dampness.

Many people say that the walls contain a lot of alkali, but this is not the case. Because the building material is alkaline, our walls must be alkaline, and the alkali content of the walls is roughly the same in both the south and the north, and there is not much difference! The alkali amount on the wall is too high to let the wall be the base, which is too biased!

And most of them think that the real reason for the alkalinity of the walls! One of the main reasons why walls become alkaline is that the walls are wet. This includes the cause of whether the walls are damp or the rear is wet.

For example, when our walls are not dry, it takes a long time to use putty or paint! This is a clear manifestation of the wall! For example, the walls shared by our bathrooms and living rooms are also the areas most affected by alkali because the walls are caused by the humidity of the bathroom.

What is the reason for the reputation of the alkali on the wall- Caused by moisture on the wall.

It's not hard to see why. Many of our floors, basements or first floor bedrooms are poorly ventilated. The hot air flows to the ground and returns after the cold.

It forms moisture on walls 20-40 cm above the ground, which are exposed to moisture. Alkali and salt can create alkaline, decomposition and flaking problems on the walls. This is also the reason why most wall bases are close to the ground.

The alkali of the outer wall is usually also present at the root of the wall and is due to rainwater falling on the outer wall and the lower part of the wall. There were also raindrops falling on the ground, and the rain soaked the walls.

What is the cause of the alkali on the wall, so the smile is fine- The walls have a high alkali content.

The high alkaline content here refers to some saline-alkali areas, such as coastal cities such as Shandong and Fujian. The building materials used have a high alkaline content, including the structure of groundwater and a high alkaline salt content. But this reason is rare in non-coastal cities.

The main reason why it is not a seaside city is the humidity inside the walls and the humidity outside!

The above isWhat is the cause of alkali on the wall?I hope that the introduction of what causes alkali on the wall will be useful to you.

You can get it for free

In our life, we often encounter the phenomenon of a layer of hoarfrost on the wall, which is actually due to the wall dampness or waterproof function is not done well and causes the wall alkali phenomenon, which will seriously affect the indoor beauty and needs to be dealt with in time, so how to deal with the wall alkali, the following article will introduce it to you.

1. Completely clean the wall.

First of all, use a shovel to remove the putty on the peeling wall, and then use a wire brush to brush off all the alkali scale and floating ash on the surface.

2. Use alkali elimination paint to apply to the wall.

We can buy some alkali elimination coatings on the market, such as alkali elimination No. 1 AB group, etc., and brush them on the wall that has just been cleaned after mixing, and we need to ensure that there are no gaps in the wall when brushing, so as to prevent the occurrence of alkali on the wall to a certain extent.

3. Re-scrape putty and paint.

After waiting for the wall to dry for 24 hours, we can re-scrape putty and level the wall, and then apply latex paint or paste wallpaper, so that there will be no alkali return in front.

What are the causes of alkali on the wall?

1. Indoor waterproofing is not done well.

If the indoor waterproofing project is not done well, it will lead to leakage on the wall, which will cause the wall to become damp and the moisture cannot be dissipated.

2. The original wall surface is damp.

Usually when we decorate the house, the house is a newly built building, the wall humidity is nothing more than **, the wall of some houses is relatively wet, and the later putty powder latex paint causes too much moisture inside the wall, which is easy to lead to alkali on the wall.

3. Caused by moisture on the wall.

Most of the wall alkali occurs on the first floor or in the basement, mainly because the ventilation in these places is relatively poor, and the hot air flows to the ground and turns back after being cold, which will form moisture on the wall, resulting in alkali on the wall.

The thorough treatment method of wall alkali is as follows

1. It is only the phenomenon of alkali return on the surface

It is mainly caused by the poor compactness of the material inside the material and the easy absorption of water. When the material contains alkaline impurities that are chemically unstable, salts, such as carbonates, will form when it encounters acid rain, and white crystals will appear on the surface after the water evaporates.

Resolution

If this is the case, the treatment method is mainly surface cleaning, which can be combined with the surface contamination of the material during use and acid rain reaction, and a certain proportion of oxalic acid solution can be used for regular cleaning.

2. Permeation crystallization

It is mainly caused by the high water absorption rate of the exterior wall material. Some water-soluble chemicals will be immersed in the stone through the capillary tube in the stone, through the water as the carrier, the surface material micropores as the channel, the water, alkali, salt and other substances in the bonding material infiltrate and precipitate, after the water evaporates, the white saline-alkali crystals will stay on the surface of the stone, and the phenomenon of alkali return occurs.

Resolution

When processing, it is necessary to purchase surface materials with higher density and cement materials with low alkalinity, and then use the dry hanging construction process to avoid wet pasting. Finally, the waterproof treatment is done, the concrete or cement plastering layer is coated with waterproof materials, and then the paste is used for construction.

How to maintain the interior wall

1. General stain cleaning

Indoor walls are often covered with stains, once you find that there are stains on the wall, you should deal with it in time, if it is a water-resistant wall, you can scrub it with a rag, and then blot it with a dry towel. If the wall is not resistant to water, then you can only wipe the wall with an eraser.

2. Special stain cleaning

If it is a stain that is difficult to remove, then you can use fine sandpaper to gently polish the stain off, and then repair it with wall paint, and the wall will be clean.

3. Treatment of mildew phenomenon

Indoor walls often have mold, especially near the walls of bathrooms and kitchens, which are prone to mildew and affect the appearance of the walls. In the face of mildew, you can wipe it with bleach, which can not only remove mildew on the surface, but also disinfect.

The thorough treatment method of wall alkali is as follows

Tools: Shovel, wall separator, putty plaster, latex paint.

1. Use a shovel to remove the alkali position of the wall, and then clean the wall hygiene, no dust and stains, and then keep the wall dry enough.

2. Use a special wall separator to paint it on the treated wall. Generally speaking, it should be applied 2 or 3 times, and each application needs to wait until the previous one is dry.

3. After painting the release agent, wait for 24 hours, and then use putty paste to scrape the wall. Then wait 5 hours for it to dry, and then sandpaper the wall to smooth out.

4. After the putty paste is completely dry, you also need to brush a layer of latex paint on the surface of the wall, which is generally more than two times of construction, and finally wait for it to dry naturally.

The cause of alkali on the wall

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. Caused by water leakage upstairs, 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.

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.
