Why does the wall fall off the skin? What is the reason for the wall skin

The reasons for shedding are:

1.Problems with the contact surface of the base layer: apply latex paint.

When the wall is not clean, the workers are lazy and do not polish and clean the wall, resulting in the adhesion of latex paint is not strong;

2.Weather or environmental issues.

During construction or use, long-term exposure to a humid environment leads to excess moisture in latex paint, and when the wind blows or the weather is dry, the latex paint will shrink and tighten, resulting in peeling. For the former phenomenon, it is better to consult during construction, and in the latter case, for example, to brush latex paint in the bathroom, you had better choose waterproof latex paint.

3.Wall cause: Although your wall is a new wall, it does not exclude this reason, and a bad wall will also cause the surface to crack and fall off.

4.Reason for latex paint products: Don't say much about this reason, you choose not good paint, fake and shoddy products or brands with poor qualifications.

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!

Emphasizing that the skin is mainly due to too much moisture around the robbing, the wall is too wet, and the skin of the wall is not firmly glued to the wall and the skin falls off.

The reason why the wall skin will fall off is because of the humid air, which is the phenomenon of the wall skin falling off in Guangdong. So you should have gout to make his walls dry.

The wall skin will fall off because the water of the wall itself is too large and the adsorption capacity is weak, that is, the wall has some anti-water. It could be caused by a water leak in the house.

This wall skin peeling is caused by the dampness of the house, because this dampness will make the wall skin fall off, so quickly find someone to repair it, so it will be fine.

Hadron will fall off the wall skin, that is because the wall skin and the wall are separated, especially the wall that has been in disrepair for a long time, the wall skin is easier to fall off, and the wall skin can be scraped again after falling off.

There are many reasons for this, it may be that the wall is damp, it may be bumped by external forces, and it may be that the construction has not been handled well at the beginning

The original primer is easy to peel off if it is not shoveled. So the original one had to be shoveled out. If you remove the wall skin and see if there is any water seepage.

Rose, so will peel, it is because the quality of his material is not good.

1. Generally, there will be a process of foundation settlement in a new house for one or two years. During the settlement process, the wall stretches, which will cause wall cracks or wall peeling and cracking. In the process of foundation settlement, do not rush to partially repair the wall, it is best to wait for the settlement period of 1-2 years to gradually stabilize before starting to repair the wall.

2. When the developer delivers the house, the wall is smoothed with plain ash, and the workers must shovel off the plain ash of the base layer and re-brush the primer when painting the wall. If the workers do not clean the base layer in the decoration, it will cause the wall to peel and crack for a period of time after brushing the latex paint.

3. Some decoration companies cut corners in order to save money when decorating for the owners, and the ratio of raw materials is unreasonable, for example, too much moisture in the 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.

1. Smooth the falling shovel, and grind it flat, then scrape the putty and apply the primer, and repeat the operation three times. 2. If the peeling is very serious, all the walls should be leveled, and then leveled with gypsum, pasted with mesh cloth to judge the cavity, and scraped the wall three times, and then polished and flattened, the effect will be better. 3. Or you can directly use fine sandpaper to polish the peeling place, and brush the new primer and topcoat again after processing.

The reasons for this situation: 1. It may be that when the house was renovated, it was not often supervised, so the construction team was not careful during the construction, and some steps were omitted if they could be omitted, so the wall peeled off in the later stage. 2. Or when painting the wall, the second layer was painted without waiting for the previous layer to dry thoroughly, and this kind of accident will occur after a long time.

3. Either the environment at home is relatively damp and caused by lead limbs, or the sunlight at home is too good, often directly hitting the wall, resulting in the phenomenon of peeling, or it may be that when purchasing materials, you bought inferior materials.
