Is the white paint on the wall at home often falling off because the wall is too damp?

Many friends will use white paint in the decoration at home, and after a few years, they will see the wall paint slowly bulging, and even say that it has fallen off, so why does the wall skin fall off? Let's walk into the real reason behind the paint with you. <>

The wall skin is bulging and falling off, which may be caused by many reasons. On the one hand, it may be that the quality of the paint is not up to standard when it is renovated. If you don't use good materials, it can lead to primer and putty.

There are gaps between them, so that air can take advantage of the opportunity to enter and cause the bag to take up. After the bag is lifted, the gap will become larger and larger because of the chain reaction, which will eventually lead to the peeling off of the wall skin. On the other hand, because the walls are damp, this situation mainly occurs in rooms with more water pipes such as kitchens and bathrooms.

These places, because of the influence of water for a long time, so among them latex paint.

The hydration resistance is poor, it cannot withstand the erosion of water, and gradually loses its adhesion, and there will be falling off and even powdery falling. <>

It is necessary to truly solve the situation that the wall is damp and the wall paint falls off. First of all, it is necessary to remove these peeling paints, clean up the entire wall, solve the bubbling part, and re-smooth this part of the wall. Then reapply with plaster powder.

Re-layout. After the treatment is done, the putty is reapplied, and the wall is sanded again and the primer is applied. If the peeling of the wall is more serious, it depends on whether the wall has been seriously eroded.

Like an old-fashioned house, the wall may have been eroded by water and cracks due to too much time, so you should contact the construction team in time to make an assessment of the safety of the walled house. If there are cracks in the wall due to moisture, if necessary, the old wall should be demolished again, and the construction should be carried out comprehensively, and the paint should be refreshed and covered with cement to solve this phenomenon. <>

To sum up, the wall falling off is a relatively common phenomenon, as long as we recognize the problem from which side, and then deal with it in a timely manner according to the relevant situation, we will be able to properly solve the problem, so as to make our home environment more beautiful.

Severe cold indoors and outdoors or temperature differences caused by air conditioning can affect the walls and cause peeling.

It may be caused by the quality of the paint or the quality of the construction, but if there is only a small area falling off at the bottom of the place, it is recommended to shovel it.

One is that when the wall foundation is wet, the paint is painted before it is completely dry, and the second is that the wall is damp due to the high moisture in the air during the rainy season, both of which are moisture infiltrating into the paint surface and causing the paint film to lose its adhesion, resulting in peeling and peeling.

This is due to the fact that the paint has been painted too many times and the quality of the paint is not particularly good. As a result, the wall skin has deteriorated, so it will fall off.

Yes, there is often a resurgence of moisture on the wall, and there is no way to ensure the temperature in the room, and the white paint will fall off.

There are many reasons why the wall is white and falling off, which are mainly divided into the following types:

1.Material problems: If the wall shed is made of poor quality building materials, such as gypsum board, inferior fiberglass cloth, etc., it will cause the wall to fall off.

2.Process problems: If the pasting process is improper and the paint is uneven, it will also cause the wall to fall off.

3.Humidity problems: If the air around the wall is humid, or if there is water seepage in the wall itself, the white coating on the wall will peel off.

4.Ageing: If the building has been in use for a long time, or if the old white coating on the wall has deteriorated, it will fall off.

5.Wall problems: If the wall surface is uneven, there are silver cracks, or uneven unevenness, it can also cause the white coating to peel off.

The above are the common reasons for the wall to fall off, and different maintenance methods are required for different reasons to maintain the beauty and durability of the wall.

First of all, it is necessary to understand that the reason for the peeling off of the wall skin is generally caused by improper treatment of the base layer or the wall is damp, mildew and other problems, generally speaking, the relationship with the paint and putty is not too large, unless too much putty is used.

Get the right medicine. First of all, the wall paint and putty are completely removed until the cement layer or red brick is exposed, and then dried thoroughly (if it is damp, the fundamental problem of dampness must be solved first) If it is a red brick wall, there is no cement layer, then it is necessary to cement leveling (plain ash can), dry thoroughly, paint the wall solid (or 108 glue), dry thoroughly, put the first putty, polish and flat, dry thoroughly, put the putty on the second time, dry it thoroughly, polish it flat, and then deal with local details (local unevenness should be leveled), Finally, the putty should be thoroughly dried and polished, and the latex paint primer should be applied once, and the top coat should be applied twice, if it is a white wall, it will basically be completed, if it is a colored wall, it will be painted with a layer of paint, and in order to stabilize the color, the colored wall should be brushed with an additional layer of paint!

In the daily maintenance of the latex paint wall, it must not be damp and mildew!!

When it gets wet, keep it dry indoors.

Obvious manifestations of moisture in putty.

Method: Remove the putty layer, put water-resistant putty or inorganic substrate on the wall, and then use inorganic topcoat (no latex paint) to solve the problem completely.

1. Why does the first floor of the house get damp, moldy, black and peeling?

Second, what to do if the wall is damp and mildew

In such a situation, you must open the windows and doors in time to ventilate, be sure to do a good job of ventilation, and then you can also choose to dry with a hair dryer, or you can choose to use a heater to dry, and then paste wallpaper or repaint.

You can go to treat it with bleach, you can also buy some related alcohol, and secondly, you can scrape off these moldy wall skins, and then repair them, and you can smear some lime.

In these cases, the first thing to do is to dispose of the moldy part of the home, add some new paint, and pay attention to ventilation after drying.

In this case, you first need to negotiate with the renovation company, because there is only one month, and they should be responsible.

If the renovation company can't solve it and needs to deal with it yourself, then the following solutions are provided for you:

1. Use dehumidifiers. The room is damp, and desiccant and activated carbon can be used to prevent moisture and absorb moisture. Desiccants and activated carbon can be used. There are many desiccants in supermarkets that are specially used for moisture-proof and dehumidification, and the common ones are two types: moisture absorption boxes and dehumidification bags.

2. Buy an air dehumidifier, it is like a vacuum cleaner, it can concentrate the wet air together, and when the moisture is wet, it will turn into water many times. Dehumidify with air conditioning. Air conditioners used in the home generally have the function of dehumidification, but the way of adjusting the humidity of the indoor air is slower, generally takes two or three hours, and it will make the people in the room feel cold.

3. Use lime and bamboo charcoal to dehumidify. Use a small cloth bag to fill an appropriate amount of lime, tie it into a bag and place it in all corners of the room, the lime itself has the effect of moisture absorption, and can also slow down the indoor damp situation, at the same time, the lime also has a disinfection effect, killing two birds with one stone.

4. When the outside moisture is heavy, the doors and windows should be closed to prevent moisture and moisture. In normal times, windows should be opened more for ventilation.

The home has been renovated for less than a month, and the white walls are damp, moldy and falling off, what should I do I should immediately increase the temperature in the supermarket Eliminate the moisture in the room and strengthen the indoor ventilation.

In fact, in such a situation, it is best to find some professionals, because it may be that your hand is not properly done to cause such a situation, and it is important to see if there is a water leak upstairs. Therefore, you have to find some professionals to see clearly.

After seeing the problems on the walls of your home decoration less than a month, you can go to the home improvement company to ask for an explanation, a month is still within the warranty period, they should redecorate the wall for you.

Isn't it when you decorate, you are not very noisy inside, and even love your house, hey. The penalty for not opening the window is the punishment for not taking this tuoluo, alas, this thing is possible, so you can't close the windows very tightly during the Mid-Autumn Festival, you should let it ventilate. It's okay to get past something you can't do with this kind of love, even to the point that even the smell of that uh sleeve let him out.

This shows that they didn't take care of the walls properly, and these walls seeped water, causing the current situation.

It means that the alkali has returned, and there is water vapor in the wall, so it is not recommended to deal with it immediately, and wait for the water vapor inside to run out and deal with it

To find the cause of dampness, only if it is not damp can be repaired, the falling off from the new shovel, and then hang putty to repaint.

If you come across a house with high humidity all the time, such as a bathroom, then you have to paint the exterior walls, waterproof, and do it indoors.

1. Shovel off the damp part with a shovel.

2. Re-scrape the wall with gypsum putty, and polish it with fine sandpaper after drying.

3. Repaint the coating, preferably waterproof coating.

There is no way, shovel it all out, wait for it to dry and do it again.

Remember that the removed part must be larger than the original area removed. Take it as a limit that you can't easily shovel.

If the wall is damp, it is normal for the local climate to be humid or the back of the damp wall is damp, and the wall is damp due to water seepage from the back.

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.

1. The waterproof gypsum board needs to be replaced when it is wet.

Restroom leaks are one of the most common water leaks. Generally speaking, bathrooms need to have suspended ceilings, and the flooded walls will be hidden, so no special treatment is required. The commonly used material of the ceiling is the aluminum gusset, and after solving the water leakage problem, as long as the aluminum gusset is wiped clean.

2. Pay attention to the temperature and humidity of the latex paint wall.

Owners who have requirements for the construction period need to pay attention to the temperature and humidity during construction. If the repair area is less than 10 square meters, the natural drying of the wall will take five or six days in spring and autumn, and about 10 days in the humid summer; Generally speaking, the best construction temperature is 20, if the indoor temperature does not reach 5, the latex paint film is not easy to form a film, and it also takes about 10 days. If the repair area is more than 10 square meters, the construction period may need to be extended.

3. It is best to replace the damaged wallpaper as a whole.

When a wallpaper is wet, the wallpaper may warp, deform, and discolor. Different from the wall of latex paint, there is no requirement for temperature and humidity in the face of repairing the wallpaper wall, but the color difference of the damaged wallpaper wall is inevitable, and it is recommended to replace the wall wall as a whole.

What to do if the wall of the room at home is moldy.

Many people think that the wall has mold, wipe off the mold with a rag or repaint the wall can be solved, in fact, this is a very wrong idea, this can only be temporarily eliminated or covered, can not be completely eliminated, invisible to the naked eye is not equal to **, after a period of time mold will appear again, and will become more and more serious. Because wall mold is a kind of bacteria with strong vitality, if its growth environment is not completely eliminated or its bacteria are killed, it will multiply and spread rapidly in the corresponding environment.

There are only two ways to remove mold from walls:

1. Use high-quality building materials to redo a thorough wall transformation, do a good job of external wall insulation (note, it is external thermal insulation, external wall insulation and external wall internal insulation are completely different), block the conduction of heat by the wall, and only do external wall internal insulation can not fundamentally solve the problem.

2. Use "fungicide" to remove. Fungicides are classified according to microbial species in the process of making cheese, and are used to ferment and mature specific microbial cultures of cheese, which mainly include Lactobacillus, Lactobacillus, Streptococcus thermophilus, Leuconostoc, Pediococcus, Enterococci species, subspecies and variants. It can effectively remove mold on the wall.

To sum up: what to do if the wall of the room at home is damp, we must do a comprehensive analysis, and when the wall is damp, we must choose a good way to alleviate such a problem, only by doing these can we change our own life and living environment, so that we can live in a comfortable environment. ‍‍

First of all, we must find the cause of moisture, first deal with the problem of dampness and then deal with the wall, the wall can only wait for the original wall to dry, shovel off the original wall, scrape putty again, and then apply latex paint primer and topcoat in turn.

The place near the bathroom in my house is also damp, so I shoveled off the damp wall and painted it with cement paint.
