The cause of the peeling of the wall skin, the peeling of the wall skin, what could be the cause?

The culprit who caused the wall skin to fall off!

The first "key offender" that can make the decorative layer (wall skin) on the wall fall off is the leakage phenomenon! Because once the wall leaks, it will separate the putty powder decorative layer on the wall from the wall, and finally it will be unable to withstand the attack of leakage, and it has no choice but to "part ways" with the wall!

The real situation: there is a leakage phenomenon on the wall, and the water affects the viscosity of the wall decorations and the wall, and the long-term humidity of the wall will inevitably make the wall skin unable to adhere firmly to the wall. At the same time, the decorative materials on the wall have been eroded by water vapor for a long time, and the glue has gradually decreased, and the phenomenon of weathering in advance has appeared, so there is a possibility of falling off!

Peeling of the wall skin due to wall leakage.

The "real culprit" who caused the wall skin to fall off.

In addition to the leakage problem, the "culprit" caused by the peeling off of the wall skin, the quality problem of putty powder is also the "real culprit"! Because it doesn't really work out against water and moisture!

Putty powder not only plays a decorative role, but also should have waterproof and moisture-proof, anti-cracking and alkali-resistant effects! If these minimum requirements are not met. Then it proves that the peeling off of the wall skin is related to the quality of putty powder!

Essentials of buying putty powder: white brightness is the first choice for putty powder, and adhesion is the key to choosing putty powder! Then it's time for the brand's choice.

Many people have a misunderstanding when choosing putty powder, thinking that the most expensive is the best! But Brother Yu thinks that cheap goods also have good goods, and the level of ** is often affected by the popularity of the brand. Anyway, putty powder is to choose good quality, as for what brand to choose, Brother Yu dare not say more!

Water-resistant tempered putty powder.

The "**" that causes the wall skin to fall off.

In addition to the leakage of the wall skin peeling treatment and the quality of putty powder, the wall problem is also a reason. For example, before scraping putty, there is more dust on the wall or there are more quality problems on the wall that have not been dealt with, these problems will affect the adhesion between the putty powder and the wall, and the second will be that the wall base will fall off, and the putty powder finish will also fall off, so the problem on the wall base layer will become the "**" of the wall skin falling off!

The basic treatment of the wall before scraping putty: the first is to clean the wall and clean the dust on the wall. The second is to do the wall maintenance work, check whether the wall has a loose hollow drum, find that the wall has quality problems should be dealt with and then scrape putty work, if necessary, you can use the wall solid to improve the wall problem!

Brush the wall solid. The "accomplice" who caused the skin of the wall to fall off.

In addition to the above-mentioned "main culprits", there will also be some "accomplices" involved in the phenomenon of wall peeling. For example, the air humidity is rebuilt to the wall to be damp, the water pipe embedded in the ground is leaking (including plumbing works), and human factors (including construction quality), etc., these problems may cause the wall skin to fall off!

We can investigate the problems one by one, find the main cause and then take corresponding measures, and the problem can be solved!

The damp environment, poor construction quality, and unqualified materials will cause the wall skin to fall off.

What could be the cause of the peeling off of the wall?

1: The base layer of the wall is loose and pulverized.

2: There are floating ash, oil stains, film removers, etc. on the surface of the base layer.

3: The water content of the base layer is too high.

4: The construction team works in a high humidity environment.

5: The coating has frozen before it dries completely.

6: There are cracks in the insulation layer of the original room, resulting in cracks on the wall during decoration.

7: Improper repair and painting of the wall after slotting, resulting in shrinkage cracks in the wall.

8: When plastering, the cement ratio is not suitable, and the proportion is too high and it will crack.

9: The proportion of wall putty is not appropriate, or it is scraped unevenly.

10: The ratio of latex paint to water is not appropriate, resulting in cracks on the wall.

Wall peeling treatment method:

1. Directly roll the topcoat to cover the part.

In the event of simple discoloration, it is generally recommended to use a roller brush to cover a new round of primer and similar topcoats. However, before construction, it is necessary to judge the quality of the wall putty layer at this time: select the part of the wall with the most serious discoloration, soak it in water and use a shovel to smooth it vigorously.

If there is no chalking or peeling (indicating that the original putty layer is of good quality), you can use fine sandpaper to sand and then refresh the primer and topcoat.

2. Remove the flaking part and reapply the putty.

If the white or bare wall is partially bulging or slightly cracked and peeling, the problem can be eliminated and the edges of the eliminated part can be smoothed out, then putty is scraped, primer is applied, and then paint is applied, but it may be slightly different from the original wall.

3. Demolish the old wall, construct and update it as a whole.

Comprehensive construction is the same as redecorating. The quantity is: It is suitable for walls with many cracks, spalling and dusting.

First of all, the wall should be completely cleared to the cement layer. For some houses that have not been renovated for a long time (such as before the 80s of the 20th century), it is more necessary to remove the surface of the brick wall, and then carry out comprehensive construction and renovation of the wall: wall leveling - base curing - brush interface agent - brush waterproof putty three times - wall polishing - brush primer - brush twice effective topcoat.

4. Grassroots professional reinforcement.

In case of severe local spalling, it is necessary to consider whether the foundation of the wall has not yet been completed. The original wall should be moved to the base layer of the wall, re-brushed with interface agent or primer, and then polished and smoothed after plastering plaster leveling three times, pasting mesh cloth (reinforcement and anti-cracking), and scraping the wall lining. At this point, the quality of the entire base will be better.

If the wall skin falls off, it may be due to the average quality of the material, or the foundation is constantly sinking, or it may be exposed to strong direct sunlight for a long time, or it may be affected by moisture during the rainy season.

It may be caused by the waterproof layer falling off, it may be caused by the unqualified cement layer, it may be caused by improper treatment, it may be caused by the poor quality of raw materials, or it may be caused by too thick plastering.

It may be caused by dampness at home, it may be caused by poor quality, it may be caused by poor production process, it may also be caused by poor quality of the wall, or it may be caused by pressure.

The reason for the peeling off of the wall skin: the base layer is not clean or improperly treated during the wall decoration construction, the quality of the prepared mortar and raw materials is not good or the construction workers are not used properly, the base layer is improperly painted, and if the one-time plastering is too thick, the dry shrinkage rate of the wall is larger.

Treatment: It is recommended to shovel off the place where the wall skin falls off, and then reapply the paint, shovel off the place where the wall skin falls off, and see if there are loose, cracked, and hollow areas in other places around the wall, and it is best to remove these areas together;

Local painting may cause a different color, at this time you can choose to do wall painting or use green plants and other shades, it should be noted that the method of painting and the layer should be consistent with the original wall decoration, the wall should be dry during construction, you can choose the same paint to apply.

Should the peeling of the wall skin be a rough house or a renovated wall? If it is a rough house, then it may be the reason why the cement label of the wall is not up to standard when it is blue; Some rough houses were originally brushed with a layer of putty powder, and the situation you mentioned may also be due to the fact that the putty powder brushed before fell off; If it is a decorated wall, then there are two possibilities, 1, according to the standard, there is putty powder on the wall before decoration but it is not shoveled, so it is dragged, 2, it is possible that the quality of putty powder and latex paint used in your decoration is not up to standard.

The above reasons are all reference standards, and the main thing is to look at the causes.

Solution: It is recommended to re-brush after childbirth, otherwise there will be a second peeling!

Summary. Hello, the peeling of the wall skin is generally a common cause of falling off caused by moisture, sun exposure, latex paint and the quality of the wall paint itself.

What is the reason for the peeling of the wall?

Hello, the peeling of the wall skin is generally a common cause of falling off caused by moisture, sun exposure, latex paint and the quality of the wall paint itself.

The simple remedy for peeling off the wall is: 1. Remove the peeling wall skin from the wall; 2. Smooth the edge of the peeling area; 3. Brush a layer of primer on the peeling area, choose the same color as the wall, and scrape a new layer of paint.

The difference between shoveling wall skin and not shoveling wall skin is different, the construction period is different, and the consequences are different.

1. **Different.

Shoveling the wall skin is equivalent to an extra layer of base treatment process when the decoration is called, so it will be higher than not shoveling the wall skin, if it is completely unnecessary for the hardcover room.

2. The construction period is different.

The time to shovel the wall skin will be 3-7 days, which will slow down the progress of the entire decoration, so the shoveling of the wall skin will delay the entire decoration period, if you are particularly concerned about the decoration period, do not do it.

3. The consequences of the chaotic chain bridge caused by the uproar are different.

We can take a look, if there is obvious wall skin powder, it is enough to show that the quality of the wall skin is super poor, it must be shoveled off, do not wait until the time of decoration, if you do not shovel the wall skin will always fall slag, and then remove it, it will become very troublesome.

The cause of the peeling of the wall skin

During the construction, the workers began to brush latex paint without cleaning the base layer, which led to the phenomenon of wall skin peeling off on the wall. The foundation of the house settles, and the wall will also stretch during the settlement process, resulting in the fall off of the wall skin. The stirred mortar is not used up in time, and the adhesion to the wall is not enough due to the long parking time, which causes the wall skin to fall off.

Sanitary partition walls are the most common part of the interior where the wall skin peels off. Because there will always be water on the interior wall of our bathroom, if the interior wall of the bathroom is not waterproofed well, then this water may penetrate into the wall. Slowly infiltrating the inside of the wall, the final result is that the patent leather peels off on the other side of the wall.

The problem of peeling off the skin of sanitary partition walls is the most common problem in the home.
