How to deal with the repeated re dampness of the wall of the new house

1. If your house has not been renovated for a long time, then when dealing with the old wall, you can keep some of the original water-resistant putty, and there is no need to remove it all. Use sandpaper and a steel brush to smooth out the wall, and you can apply latex paint after sanding.

2. If it is a painted wall, it is more difficult to repair, and it is difficult to achieve the desired effect, so when we deal with the old wall, we must repair it comprehensively, and it is recommended to repair the whole wall or expand the scope of repair as much as possible for the damaged wall, so as to avoid the color difference of the wall after repair.

Alkali reflux on the wall of the new house refers to the appearance of alkaline substances on the surface of the wall after the decoration of the new house is completed, after the moisture and moisture phenomenon appears on the wall. This phenomenon often has a detrimental effect on the aesthetics and overall quality of the wall.

The reason for the resurgence of moisture is first of all because after the renovation of the new house, the ground and walls are damp and have not completely dried. Secondly, factors such as temperature and humidity in the room will also directly affect the state of the wall of the new house. It is also possible that some building materials and processes were not suitable for the construction of the building, resulting in the inability of water vapor to be discharged in time inside the building.

There are many reasons for the resurgence of alkali on the wall of the Jue Ming Dynasty, but from the perspective of solution, a series of measures need to be taken. First of all, you can build a dehumidifier to reduce the humidity in the room as much as possible, and appropriately raise the room temperature to promote the evaporation of moisture in the new house materials and help reduce the moisture regain phenomenon on the wall. Secondly, the alkali return and falling off of the surface of Suiling can be treated by grinding, scraping and other methods.

In addition, it is very important to protect the floor slabs and floors from moisture and waterproofing. Decoration materials such as wooden floors and painted walls need to be moisture-proof and waterproof to prolong the service life of decoration and housing, and also avoid possible health problems.

In short, the wall resurgence alkali is a common quality problem after the decoration of new houses, and the solution needs to comprehensively consider factors such as environmental humidity and temperature, and take measures such as dehumidification, dust scraping, and moisture-proof to avoid adverse effects on the normal life and health of the owners.

The wall surface has returned to alkali due to moisture, and this kind of problem needs to be dealt with as soon as possible, and the following are several methods:

1.Replace the damp area: If the area exceeds 5%, the damp part needs to be replaced.

First of all, use a shovel and a scraper to remove the loose lime and dust on the wall on the surface of the original wall decoration, and then use a plasterizer to touch a thick and wide layer of thin waterproof mortar, and after the mortar is dry, the wall can be painted, and the wall problem can be effectively solved.

2.Cleaning and batch scraping: Wash the walls and use a scraper to fill in peeling lime, waterproofing materials, and small cracks in pipes. Scraping a new layer of waterproof material and then smiling and polishing can effectively prevent the generation of alkali return.

3.Moisture absorption: In order to prevent the problem of alkali return due to moisture, attention should be paid to maintaining indoor ventilation, so that the wall can be naturally dispersed and ventilated as much as possible.

A hygrometer can be used to measure the humidity in the air to keep the humidity in the room between 20% and 60% of the stool, and a dehumidifier can be used to reduce the humidity in the room.

4.Use waterproofing agent: The pores of the wall are easy to let the water vapor in the air enter the wall, enhance the impermeability of the wall, and the use of waterproofing agent can effectively prevent moisture from entering the wall and avoid the return of water to alkali.

In summary, when dealing with the damp and alkaline wall, it is necessary to keep the indoor ventilation frequently, remove the moisture in time, and also use cleaning, ash, moisture absorption, and the use of waterproofing agents to reduce or prevent problems.

The alkali return of the wall due to moisture is due to the moisture inside the wall penetrating into the surface and bringing out the alkaline substances inside the wall, resulting in the appearance of white powdery substances on the wall. Here's how to deal with it:

1.Cleaning: Wash the walls with clean water and neutral detergent to remove dirt and alkaline substances from the surface.

2.Drying: Dry the wall thoroughly to ensure that the moisture inside the wall has completely evaporated.

3.Moisture-proof: Paint moisture-proof paint on the wall to prevent the moisture inside the wall from penetrating into the surface of the buried brigade again.

4.Neutralization: Apply a neutralizer on the wall to neutralize the alkaline substances inside the wall and prevent the return of alkali again.

5.Redecoration: If the wall is seriously damaged by moisture and alkali return, it is recommended to redecorate and repaint or tile the wall of the curved stool that has been judged to be orange damaged.

It should be noted that the moisture and alkali return of the wall is caused by the moisture problem inside the wall, so it is necessary to fundamentally solve the moisture problem inside the wall, such as strengthening waterproof measures and improving ventilation.

1.Cleaning the wall: First of all, you need to clean the dirt, oil, and dust on the wall, which can be cleaned with water or detergent.

2.Alkali reflux: Use a special alkali reflux or acid cleaner to remove the alkali reflux on the wall.

It is important to note that when using acidic cleaners, avoid contact with metals to avoid chemical reactions. 3.Neutralization and alkali return:

A special neutralizer is used to neutralize the alkaline substances on the wall to prevent the recurrence of alkali return. 4.Moisture-proof treatment:

Apply moisture-proof agent to the wall to prevent the wall from getting damp again and causing alkali return. 5.Enhanced ventilation:

Keep the room well ventilated so that the walls are dry and the hail is not accompanied by a chance to reduce the ability of damp rocks to dry sails. 6.Repair the wall:

If the wall is already damaged, it needs to be repaired to prevent the re-alkali regression.

Alkali return to the wall due to moisture refers to the moisture in the wall penetrating into the surface and bringing alkaline substances, resulting in problems such as dampness, mildew and alkaline salt deposition on the wall. The method of treating the damp alkali return of the wall is as follows:

Remove damp parts: First, remove damp and damaged parts of the wall, including damp, moldy, and peeling coatings. Use a scraper or sandpaper to remove the damaged surface material.

Dry the wall: Make sure the wall is completely dry. You can use a fan, a dehumidifier, or open windows for ventilation to speed up the process of drying the wall. If you find that there is a leakage problem in the wall, you need to solve the leakage problem first to ensure that the wall is no longer wet.

Clean the walls: Wipe down the walls with detergent and messy water to remove any remaining stains and salt. Use a sponge or soft brush to gently wipe the wall to ensure thorough cleaning.

Use an alkaline barrier primer: Choose an alkaline barrier primer that is suitable for wall coverings and follow the product instructions. Alkaline barrier primers prevent alkaline substances from penetrating into the coating surface, providing a protective layer to prevent the recurrence of alkali return problems.

Renovate the wall: Once the alkaline barrier primer is completely dry, you can renovate the wall. Choose the right paint or wallpaper and apply it according to the usual decoration method.

It is important to check the condition of the wall regularly and deal with any leaks in a timely manner to avoid the recurrence of the wall due to moisture and alkali return. If the problem is serious or you are not sure how to deal with it, it is recommended to ask a professional maintenance master to come to deal with it.

The treatment method of damp alkali return on the wall is as follows:

1.Shovel off the peeling mortar and paint: Use a shovel and other tools to completely remove the peeling mortar and paint, and clean the dust and slimming.

2.Routine cleaning: Wash the wall with clean water and a soft brush, and wash off as much alkali or salt as possible without letting them settle on the wall.

3.Hair dryer or humidifier: Use a hair dryer or humidifier to dry and adjust the wall surface affected by the dust of the first brother of the tide to gradually return to dryness.

4.Touch-up paint or repaint: After the wall is dry, after the pH value of the room is checked to be non-alkaline, it can be treated by applying anti-alkali primer, and then applying latex paint.

5.Reinforcement of the wall: If some aspects of the wall are loose or bulging due to the dampness of the wall, holes can be drilled around the surface of the wall, the depth of the drill bit is not less than 5cm, and the concentration of sodium silicate is added to thoroughly penetrate to meet the needs of the wall.

It should be noted that alkali return is a common cause of wall moisture problems, if the wall occurs alkali return, the above treatment methods should be taken in time to avoid aggravation of wall damage. In addition, to prevent the wall from being damp, pay attention to ventilation and keep the room clean and tidy are also important measures to avoid the return of alkali to the wall.

Alkali return to the wall due to moisture refers to the phenomenon that the material components in the wall are dissolved due to moisture on the wall, and a white powdery substance will be formed on the surface. Here are some ways to deal with the damp alkali return of the wall:

Clean the surface: Wash the wall with clean water to remove dust and dirt.

Dry the wall: Dry the wall thoroughly to ensure that there is no moisture on the wall, and never use auxiliary tools such as a hair dryer to dry it.

Treat the walls with a moisture barrier: Moisture repellent can be used to treat the walls to prevent the recurrence of such problems in the future due to moisture.

Finishing: After the above operations are completed, the finish can be redone, such as painting, etc.

It should be noted that if the problem is more serious, it is advisable to seek professional help to avoid greater losses.

The treatment of wall alkali return is a comprehensive problem, first of all, we must observe why the alkali return will occur, so as to prescribe the right medicine.

1. Because the stucco layer uses unqualified cement, or is mixed with admixtures with large alkali content.

In this case, it is necessary to judge that the cement of the wall is loose, if the wall is not strong, then the mortar layer of the wall must be removed, all the way to the part of the brick wall, and then clean the brick wall with 10% 15% oxalic acid, wait for drying, and use qualified repair mortar to repair the wall. The decorative layer can be painted only after 7 days of repair.

2. There is a phenomenon of alkali return at the door of the bathroom, which can basically determine whether the water vapor is seeping out from the door stone. In this case, when doing waterproof construction, the door stone part is not properly treated. Then first of all, the door stone part should be repaired, so that the water vapor of the grinding dan does not seep out from the lower part.

Then look at whether the part of the alkali return is loose, if it is loose, it is necessary to eradicate the wall, clean it with blind oxalic acid, and finally repair it with repair mortar.

3. Because the external wall is leaking and the wall is re-ignited, it is necessary to carry out waterproof treatment on the outer wall, and then treat it according to the treatment method of returning alkali at the bathroom door. 7 days after the treatment, the wall is painted with a decorative layer.

Okay, that's all for me, I hope it can help you.

The alkali return of the wall is a very headache, which affects the beauty of the building, not to mention, and the mood of people looking at it is inevitably affected. So you may not know much about the knowledge of wall alkali return. Today, I will take you to solve the questions and understand how to deal with the alkali return on the wall?

Why does the wall return to alkali? Knowledge of the relevant volt differences.

Brush the alkali wall several times with a hard brush (be sure to dry brush, wash or neutralize with acid is impossible to remove completely), and then clean up, the first putty bottom adopts the exterior wall waterproof coating construction process, that is, the construction of white cement putty powder is blended with JS waterproofing agent after the bottom, and the subsequent procedures can be carried out according to the normal coating construction process.

What is wall alkali return.

The main reason for the anti-alkali of the wall, commonly known as cement frosting, 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 product of hydration, the calcium hydroxide crystallizes in the cracks of the concrete and collects on its surface. In addition, limestone or building sand contains a certain amount of soluble alkali-containing organic matter, and the hydroxide or other alkali salt solution formed by them can easily and quickly seep out "frost salt" on the concrete surface and frost.

Qingkai. Why does the wall return to alkali?

The main body of the building is cement concrete wall, brick wall, and sand plaster wall, and the physical and chemical properties of these main materials lead to the universality of wall alkali return. Here I will not introduce the physical properties and chemical properties, simply put, the wall alkali return is directly because the cement is alkaline, so it is easy to return to moisture when it rains or leaks, resulting in the wall alkali yellowing and even the wall skin falling off.

Conclusion: The above content is about how to deal with the return of moisture and alkali on the wall? I hope it can help you. I believe that after the introduction of the content, you will have a good understanding of what is wall alkali return? If you have more understanding, if you have a need in the future, you can refer to it.

Due to the very humid weather in the south, the walls of the home often appear to be damp and alkali, which makes people have a headache and don't know what to do. Since putty is alkaline, it will return to the wall when it is wet, and the wall is prone to yellow marks after drying, especially at the wet and dry joints of the wall. So,The treatment method of the wall surface is damp and alkali returnWhat are they?

What is the cause of the damp alkali return of the wall?

The treatment method of the wall surface is damp and alkali return——Moisture treatment of wall tiles.

When the tile is wet, it changes color, it darkens, and when the tile dries, it returns to its original color.

The treatment method of the wall surface is damp and alkali return- The wallpaper is damp.

After the wallpaper wall is wet, the wallpaper may appear bulging, warped, and discolored. Unlike emulsion walls, there is no need to repair the walls of the wallpaper to cope with the temperature and humidity, but damaged walls will inevitably produce color differences. It is recommended to replace the wallpaper on the wall as a whole.

When repairing the wallpaper wall, peel off Nathan's damaged wallpaper, directly brush the wallpaper glue and paste it.

The treatment method of the wall surface is damp and alkali return——Cement soil alkali return.

For cement walls that already have alkali, they should be cleaned and then treated. First brush several times with a hard brush (the brush must be dry, washing or neutralizing the acid is impossible to completely eliminate), then scrape the first layer of the mastic, after which it can be updated according to the normal process.

First, clean the cement surface with a hard brush; Use high-pressure water hoses in sturdy locations. For substances that cannot have water, first wash with a diluted light acid, such as 5-10 hydrochloric acid solution. When using light acids, care must be taken to protect the clean wall from acid attack.

After cleaning the alkaline parts, use sealants, paints and high-efficiency waterproofing coatings to prevent re-alkalizing.

1. Under normal circumstances, there are many substances in the decoration that have been damaged by floods, such as nitrates and alkali salts in bricks and other decorative materials that will return to alkali with the evaporation of water.

2. If the walls of the room dry quickly, then the base salt will be fixed in the decorative materials, and the alkali prevention usually does not delay the situation, but if it is a slow dry wall, or the finished wall of the building passes first, do not wait for complete drying, and do the next layer of construction, it is possible to precipitate alkaline salt, which is what we call an alkaline wall.
