What causes moldy peeling on the living room wall?

The cause of moldy and peeling of the wall paint can be roughly divided into two situations:Due to poor indoor ventilation, it is very easy to cause mold and peeling of wall paint, which is mostly seen in restaurant kitchens, toilets and windowless dark rooms. In a similar situation, the only way to maintain indoor ventilation is to find a way; In the case of mildew and peeling caused by water seepage and leakage, it is necessary to find the leakage water resources first and solve the difficulties from the root cause in order to cure both the symptoms and the root causes.

If it is a little leakage caused by wall problems, and it is very difficult to completely eliminate it for a while, it is proposed to remove the leaking wall putty powder layer, brush the waterproof wall tiles, so that even if there is a little leakage after that, it will not cause the wall to grow mildew, and there is another situation in the peeling, especially the renovation of the second-hand house is very easy to cause, because it is caused by immediately brushing the paint on the original wall paint, this kind of situation proposes to remove the original wall putty powder layer, batch putty paint again, or polish the overall paint surface to the putty powder layer, and then apply the wall paint again.

There is also a situation in North China that is more common, after the temperature is reduced to below zero, the corner of the wall or the location of the outdoor temperature difference will produce wall peeling, mildew, this kind of situation is common in old housing, the wall has no thermal insulation layer, because the indoor and outdoor temperature difference is large, the indoor air quality will solidify into water vapor when it touches the wall and other areas with low temperature, which adheres to the surface of the wall, resulting in the peeling of the wall and mildew. The first and second cases only need to block water resources and do a good job of waterproofing the wall to deal with it, <>

The third situation is very inconvenient, and you must do wall insulation to deal with it! The quality of waterproof architectural coatings is also an important part of wall waterproofing, if the master wants to make a price difference from the purchase of raw materials, the quality of waterproof architectural coatings bought cheaply is very poor, and the actual effect of brushing a few layers is not waterproof. Brushing waterproof paint is the same as brushing wall paint, temperature and weather are all one of the hazards.

If you paint in a wet and cold day on a rainy day, or if you do not properly adjust the drying time of the waterproof paint according to the temperature and temperatureAnxious to do waterproofing, waterproof paint is equivalent to a white brush.

It is very likely that there is water vapor condensation on the wall, and the waterproofing measures are not done well, and the water pipe buried in the wall is leaking, so this situation will occur.

I think it's because the material of this wall is weathered, or the material that is often splashed with water on this wall is a little damp and will peel.

It may be that the wall is too wet, and the dry and wet separation is not done, and the wall is not dried.

1. When mopping the floor every day, the water on the mop will sometimes splash on the wall, which can also cause mold on the wall. If there is a large temperature difference between indoor and outdoor, the moisture in the room will condense on the wall, and mildew will slowly appear after a long time.

2. Or the house has been flooded before。Even if the walls have been repaired, they will still look like they are moldy.

3. Moisture will mold, and the decorative materials are not waterproof。The first thing to look at is whether the wall with small mold is behind the bathroom. If it is a bathroom, then the bathroom waterproofing is not done well.

Musty walls pay attention to the point

There is a lot of mold in the moldy wall, if the bedroom space is closed and not ventilated, and the air circulation is not smooth, these molds can easily enter the respiratory tract when they flow in the air, causing human respiratory diseases, and may also cause allergies and ** diseases. Therefore, if the bedroom walls are moldy, be sure to clean them up promptly.

Attention should be paid to ventilation in normal times, but in humid and rainy weather, windows should be opened as little as possible. We can buy some dehumidifiers and desiccants to hang in places that are prone to mold, or use dehumidifiers to absorb moisture on the walls.

If the water pipe is leaking, the wall will seep water and will not become moldy. Mold is the result of the exchange of hot and cold air, it is estimated that your exterior wall is relatively thin, it is recommended to do exterior wall insulation will not be moldy again.

If it is close to the gable, it may be infiltrated from the outer wall, if it is the top floor, it may be infiltrated from the roof panel, if it is the bottom floor, it may be the moisture sucked up from the ground, and it may be caused by the leakage of water pipes through the wall.

It may be that the humidity is too high, the original decoration is not in place, and the materials are not qualified. There are many factors.

damp, unventilated, seeping places.

There is a water leak on the exterior wall or roof.

Maybe it's because I use a humidifier.

Mold growth pH value, mortar putty why the wall surface of the combination of two materials with a pH value of about 12 will breed mold.

More than ninety percent of the problems of wall disease come from the high moisture content of the wall, and there are few research and development in this direction in China.

The physical structure of the putty layer and the mortar layer is easy to produce alkalinization reaction after absorbing water in the secondary curing, and the high-alkali putty material is easy to evolve into acidic bodies after absorbing water, which breeds mold growth.

If the wall is damp and moldy, it is normal because the local climate is relatively humid or the back of the damp wall seeps water, which causes the wall to be damp.

1. Thoroughly clean the peeled and damp wall with a shovel.

2. Continue to remove the floating ash on the wall to prevent the floating ash from affecting the bonding strength.

3. Evenly brush the separator with a brush and apply it 2-3 times, with an interval of about 3 hours between each time.

4. After the isolator is dried, the putty can be scraped in batches, and the batch scraping time is not less than 24 hours each time.

5. After the putty is dried, carefully polish it with No. 180 sandpaper.

6. Clean the surface dust and paint latex paint 2-3 times, with an interval of about 6 hours between each time.

If the wall is moldy and peeling, it can be stifled and treated. Refresh service is a kind of service marketing method launched by paint manufacturers and distributors, for people with high economic affordability can be accepted, for the general family may not be easy to accept the economic ability, radish greens have their own love, whether to use the refresh service or ask a master to operate, it depends on the owner's own decision. I don't know if the decoration and wall painting service is reliable?

Is it better to do it yourself or find someone to do it? You can answer this question clearly, and it is better to choose a regular decoration company. It is not recommended that the subject get the wall of the house by himself, because there are no professional tools, do not understand the wall decoration process, he can't get it, it is easy to rework, and the final result is to find a decoration company to paint the wall.

Nowadays, most of the craftsmen and masters in the countryside are not dedicated, (I don't know what is going on in the city), and most of them only focus on profit, and the question you asked is common in the countryside. Also, if the whole is like this, it may be that the decoration and construction time are too close. You have to ask a professional to see how to solve it, and I hope that the subject can meet a good person who is dedicated in the industry.

Tell you about a mold remover I used, it's very easy to use, basically just once. It's just that the smell is a bit big, you need to bring a mask, gloves, and then ventilate for half an hour and it's OK. As for peeling, only the peeling part can be removed and repainted.

Hope it helps.

Answer: Hello, your question is being sorted out, please wait a while, wait patiently, oh 1, the pipe in the wall is leaking, the wall is not waterproof enough, for a long time, water penetrating through the wall will cause mold on the wall. 2. There is a gap between the window frame, window sill and wall of the window part, or the sealing of the window is not good enough, resulting in rainwater entering the room, resulting in moisture and mildew on the inner wall, and insufficient insulation outside the wall.

The change of seasons can also lead to temperature differences, which can cause dampness on the walls.

Dear, hello, please give a thumbs up with your rich little hands, and wish you good health and all the best.

Construction reasons. It may be that the exterior wall brick inlay is not real, the brick joint is not filled enough or the joint is used, the external filling wall plastering mortar is not full enough, there are trachoma, gaps, so it will be easy to form the combination of cold and hot walls and beams and columns The filling is not dense, resulting in cracks, and the doors and windows are not densely filled when they are installed.

Nowadays, many families will have mold or peeling on the wall, in fact, it is not surprising, due to the humid environment of your home or the quality of the materials you use is not very good, which leads to mold and peeling. Either you repaint the wall, of course, you have to use a little better material, and there is also to solve the problem of dampness in the home, which is generally low on the floor. Therefore, when buying a high-rise building, we generally recommend not buying a ground floor house or a top floor house.

Another way to do this is to buy a mold remover, something similar to a spray that can effectively prevent mold from growing.

I believe everyone should know that in ordinary life, we can see that the walls of our living room may be moldy and peeling, so what is the reason for this? In fact, there are many factors for the formation of this 1 reason, because we can see our wall skin falling off in our daily life, in fact, it is mainly because our house is in disrepair. And because it takes a long time, it may cause things like peeling and molting in our house.

It is precisely because of this that we should take good care of our houses in our daily lives.

And we can also see that the house is too humid or 9 years old. If we don't clean it, it may be because we cook or have toilets all year round, which are more likely to molt because they will be soaked by damp rain and water, which will also cause them to peel off the skin of the wall. And it is precisely because of this 1 reason that it also leads us.

In the usual residence, you can see a lot of places peeling, molting and peeling wall skin, for this 1 situation, in fact, everyone can see that this situation is also more dangerous, because the wall skin may be accompanied by the wall peeling, many times. Due to this 1 reason, there will be a lot of problems, but we must do as much as possible in our daily life to minimize the wetting of wet rain, so as to ensure ours. walls in the case of dryness, durable.

Play well and exchange well. Another reason is that I can see it. If exposed to the sun, it will also cause our walls to peel and peel, which is still more serious.

And for a place that is not lived in all year round, it will lead to such a reason.

All in all, it can be seen that we still need to have somewhat. This is the most important thing to protect our walls so that they become more intact. This is also one thing that we need to pay attention to.

The wall paint is not dry thoroughly, the ground is damp and damp, the water seepage next door, the humidity of the living room is poor, and the ventilation effect is poor.

Some people will find that the wall has mildew spots in the living room after staying for a long time, and there is peeling, which makes people particularly annoyed, in fact, there are many reasons for this situation, there are reasons for decoration construction, and there are also reasons for the indoor environment later, so we must find the right reason to deal with it as soon as possible.

1. The wall is not dry when painting the wall

Most living rooms will be painted with latex paint on the wall when decorating, but before brushing latex paint, the wall must be dried before you can start painting, some decoration companies in order to catch up with the construction period and shorten the construction time, will paint when the wall is not dry, so that a lot of water will be locked in the wall, and it will blister after a long time, and the wall will peel if it becomes moldy, which will affect the decoration effect of the living room wall.

Second, the ground is damp and damp

The ground of the living room is damp, and the situation of anti-moisture will also affect the quality of the wall of the living room, and it is easy to make the wall moldy and peeling, because the ground is not found to be particularly wet during the decoration, and the ground is not waterproof at all, so that after moving in, the moisture on the ground will enter the wall of the living room along the wall, causing damage to the wall of the living room.

3. Water seepage next door

If the living room has a shared wall with the neighbors, and there is a water pipe in the wall, then when the water pipe seeps again, the inside of the wall will be wet, and the wall of the living room will be peeled and moldy.

Fourth, the living room has high humidity

The humidity in the living room is large, and the ventilation conditions are relatively poor, and the ventilation can not be ventilated in time, so that the wall of the living room is in a wet state for a long time, at this time it will absorb too much water vapor, easy to make the wall mildew, and there will be a peeling situation on the wall. To avoid this situation, it is necessary to keep the room ventilated, and keep the air in the living room dry, and ventilate it as soon as possible when the air is humid or place it in some activated carbon that can absorb moisture.
