How to deal with the resurgence of moisture and mildew on the wall of the new house, listen to what

After the renovation of the new house, the walls are peeled and there is hoarfrost inside.

How to deal with the frequent return of moisture and mildew on the wallThis? Let's take a look.

How to deal with the frequent return of moisture and mildew on the wall- If the wall is moldy and dark spots appear, you should use a dry toothbrush to clean the moldy part of the wall to avoid mold formation. Then, use a soft towel dipped in alcohol to clean the walls. Since alcohol has a bactericidal effect, it can effectively prevent bacteria from growing on the walls, making the walls dry and tidy.

If the wall is severely tidal, it can be formulated with bleaching powder and sprayed evenly on the wall. After the wall is completely dry, sandpaper is also needed for sanding and smoothing. Finally, a base coating that is moisture-resistant is applied.

How to deal with the frequent dampness and mildew on the wall- Blanch the whitening powder in a certain proportion, then pour it into a special spray bottle filled with water and spray it evenly on the surface of the mold wall to solve the mold phenomenon. Then scrub the walls with a cloth, then pour a certain amount of water and clean. After the walls are completely dry, apply anti-mildew paint to avoid moisture on the walls.

Of course, it is also possible to use a more convenient waterproofing restorant, which only needs to be sprayed on the moldy side of the wall and is easy to operate.

How to deal with the frequent return of moisture and mildew on the wall- If the surface of the wall is soft and smooth, there is no need to use alcohol to clean the wall. However, during the cleaning process, it is essential to pay attention to the effects of ventilation in the room. Since alcohol is somewhat corrosive, it is essential to have masks, gloves, and other supplies.

After the construction is completed, attention should also be paid to the indoor heating method.

How to deal with the frequent dampness and mildew on the wall- The surface of the wall is moldy, the mold points on the wall must be cleaned first, and then treated with moisture. Finally, the moisture resistance of the walls can be adjusted by a dehumidifier or air conditioner to remove excess moisture. However, this method takes a long time, usually two to three hours, and the temperature of the space is cold.

How to deal with the frequent return of moisture and mildew on the wall- The wall surface has a slight relationship with the quality of the waterproof structure. No matter what kind of wall is needed, it is waterproof, especially in the bathroom. It is often burned with hail and is waterproof to a height of about 30 cm.

If the peel chain fruit is a shower area, it should be one meter eight. Otherwise, the walls can easily seep into water vapor.

What's the deal with the resurgence of moisture and mold on the wall? What should I do? The partition wall of the bathroom mainly refers to the partition wall between the wall of the bathroom and another room.

The phenomenon at this time is that the other wall of the bathroom is always damp and moldy. Not long after pasting the wallpaper or brushing the latex paint, the wallpaper is bulging and the latex paint is peeling off. The resurgence of moisture in the partition wall of the bathroom is caused by the infiltration of water vapor into the bathroom.

Because there will always be water in the bathroom. If the waterproofing of the bathroom is not done well, it will cause the water to slowly seep along the partition wall into the other side, and there will be a situation of resurgence of moisture and mold.

For damp and moldy walls in the lower part of the exterior window, we can deal with it like this: first check the sealant around the window to see if there are any cracks. If you find that the sealant around the window is cracked, remove all the original sealant, clean the gaps, then apply styrofoam, and finally seal with structural adhesive.

Another point is to check whether the drainage hole of the window frame is clear. If not, dredge it to make sure the water flows out smoothly, not like an overflow.

There are two ways to solve the damp and moldy bottom of the exterior wall of the first floor: the first method is to waterproof the façade of the exterior wall. It is to dig the soil outside the outer wall about one meter deep, and then make a membrane waterproofing on the wall, and finally make a protective layer.

Of course, if you live in a commercial house, this method cannot be achieved. The second way is to brush the walls and floors of our homes with cement-based permeable crystals. The height of the wall brush should be about one meter, and the floor should extend by 50 cm.

Finally, scrape putty and brush latex paint. This practice can basically last for five years or more.

Water supply pipes and drains are leaking, and homeowners in northern regions should also pay attention to checking the heating pipes in their homes. The pipes leaked, and over time the walls became damp and moldy. You can ask a professional to do a stress test to test it out.

Water pipe pressure test is one of the common methods to judge whether the water pipe connection is reliable. If the pressure test fails, it can indicate that there is a leak at some point in the pressure pipe.

It is very likely that the temperature difference between the inside and outside of the house is too large, or the water pipes have penetrated; Walls can be treated with 84 disinfectant, alcohol, or bleach.

It may be that the factory is not airtight, and the humidity in the room is too high, which will cause such a situation. Be sure to remove all the problematic parts, then scrub them with alcohol and dry them thoroughly before making up for them.

Use alcohol or 84 disinfectant to treat the moldy wall, if the mold on the wall is not serious, first use a brush or a dry rag to remove the mold on the wall, it must be a dry brush or rag, otherwise it is easy to cause more serious mold on the wall. Once you have brushed the mold on the wall, wipe the wall with a towel dipped in alcohol. Use bleach to spray the wall, if there is more mildew, you can wipe it clean with alcohol, and use bleach powder with water, the ratio of bleach powder to water is 1:

99. Spray the bleach powder mixed with good water on the moldy wall. Do a good job of waterproofing and moisture-proof on the wall, our wall is moldy because the wall at home is not waterproof and moisture-proof, or the wall has water seepage, so we can paint a layer of waterproof paint on the wall after cleaning the mildew on the wall, so as to prevent the wall from becoming moldy again. In addition, we should always open windows in our homes for ventilation.

1. What is the cause of anti-moisture and mildew on the wall?

Second, how to deal with the anti-moisture and mildew of the wall?

It may be that the drainage system of the house is not good, the wall insulation is not done well, and the outdoor temperature is too low will cause the wall to be damp.

This situation may be due to the fact that the environment inside the house is relatively humid, and it may not be waterproof and moisture-proof. Therefore, it will cause the wall to be damp and moldy. There should be some dehumidifier in the room, and some activated charcoal should be put in it. In this way, the problem can be improved at the source.

Because of the environment, the air is humid and moldy. We can redecorate the house and repaint the walls.

From the point of view, the water seepage of the wall is very serious, it may be caused by water seepage, and the seepage water source must be found to be the damp situation of the wall.

In view of this situation, some more reliable dehumidifiers, such as activated carbon, can be used appropriately for adsorption, which can also be effectively alleviated. And in the room with heavy humidity, install an air dehydrating breather, which can absorb the more humid part of the air and reduce the phenomenon of moisture. The method of dehumidification with air conditioners is also very good, and most of the air conditioners purchased by every household now have the function of dehumidification.

Although it is relatively slow, it can effectively dehumidify and solve the phenomenon of mold on the wall.

There are many reasons for this, and it may be that the environment is humid, and the rainy season in the south is very tolerant of the return of moisture. It may also be that the damp-proof measures are not taken during the decoration, resulting in mold on the wall.

You can put more moisture-absorbing things in your home, such as laundry detergent. Doors and windows are also tightened to prevent moisture from entering the room.

It may be that the exterior wall of the building is damaged, it may be that the pipes are not sealed properly, and sometimes some water stains are left on the wall when washing things. You can lay some tiles on these parts, so that they can be well protected from moisture.

This is due to a problem with the waterproofing layer, which is caused by water seepage in the building, and the waterproofing treatment can be reapplied and the waterproof coating can be reapplied.

The original wall will not be dry yet, at this time we decorate the wall because of the original wall moisture caused by the wall moisture after hanging putty water evaporation infiltration, so that there will be a resurgence of moisture, if the temperature is not enough for a long time the water evaporation is not clean, there is a moldy phenomenon. Regardless of the quality problems that are easy to occur in the later stage, especially when we are in winter construction, these problems should be paid attention to, if the indoor temperature does not reach, not only in the spring of the next year, there will be a resurgence of the wall moisture, cracks and other more serious problems are possible.

Before proceeding with each step, you need to make sure that what you did in the previous step is completely dry. Among them, putty is the most difficult to dry - the base surface that does not dry slowly releases water vapor in the future, which will cause the wall to re-damp. If the waterproof layer of the exterior wall of the building is damaged, then it will cause water seepage in the building and cause the wall of the home to regain moisture.

It may be difficult to spot in normal times, but once the rain and snow arrive, your walls will experience a resurgence of moisture.

But after I moved in for half a year, in one sentence: I was so angry that my thighs were blue! In the rainy weather, the ground and walls of the house are like sweating after steaming, the water stains are one by one, and even the wall skin has fallen off

Waterproofing is not done. The wall is moldy and damp, and the waterproofing is not done well is the culprit. Under normal circumstances, the walls should be waterproofed.

Especially in the bathroom, the waterproof should be about 30 cm, and the shower area needs to be 1.8 meters. to be able to effectively waterproof.

For reverse moisture, it can be mediated with air conditioners and dehumidifiers; For mold, you can mix a certain proportion of water and disinfectant water to scrub the mold.

Mix 84 disinfectant and water in a ratio of 1:50, then use a rag dipped in the mixed disinfectant to wipe the mold wall that has been simply cleaned, brush the mold spots on the wall, and then wipe the wall with a towel dipped in alcohol.

Since the wall is damp again, then when the weather is fine, ventilate and dry the home more, if necessary, you can turn on the dehumidification function of the air conditioner to keep the house dry and help prevent mildew. As for the moldy wall, you can wipe off the mildew, and then spray it with Mrs. Ash antifungal agent, there is a concentrate to mix and treat by yourself, which is very cost-effective, so that it will not be moldy after treatment, which can kill the mold spores on the wall on the one hand, and prevent mold breeding and reproduction for a long time on the other hand. Deal with it as soon as possible, otherwise it will only get worse.

The mold is so bad that the mildew can no longer be erased, so you can use sandpaper to polish it or think of other ways, but you can't do it but redo the wall.

The first analysis may be that your home is below the third floor, or on the first floor. Because there may be some convection air even when there is no wind on the upper floors, it will rain most of the time in winter. The rainy season is one of the main reasons for the high humidity in the home, and the reluctance to open the windows in winter is also to prevent the door from being closed when people enter the house, which completely fails to meet the conditions of air circulation.

It rained for a long time, and the rainwater could flow down the vines to the facades. Because the vines and greenery are obscured, the exterior walls are in an unventilated state. The exterior walls were also wet for a long time, and when the rain stopped, the walls were also wet, and the interior walls must have been damp.

In winter, windows are not opened often for ventilation, the walls become moldy, and bacteria grow.

The drain pipe was damaged because the drain pipe of the entire building was falling down from the roof. In winter, it is the season of continuous rain, and even when the rain stops, there is intermittent water on the roof, which slowly drains out of the water pipes. When it rains, the rainwater also penetrates directly into the exterior wall, the drain pipe is damaged, so that the water flows along the exterior wall, the rain stops the drain pipe or causes the water to flow to the exterior wall for a period of time, and indoor moisture is the inevitable result.

Moreover, the indoor ventilation is not good, the walls are moldy, and bacterial growth is certain. Alcohol evaporates relatively quickly. To be on the safe side, prepare 100 kg of cold water while mixing 90 100 g of bleaching powder and leave for 30 minutes, keeping the solution concentration range between 600 ppm and 700 ppm.

The proportion used for sterilization, the dose of hand sanitizer is reduced a lot. The disinfectant solution is fully dissolved with a sprayer, and then sprayed evenly and waits for drying.

This symptom appears on the walls because of the drizzle in winter, and the air humidity is relatively high. This kind of weather is more common on the rainy side, and it is a typical "wet and cold" weather! The damp and moldy walls are also due to the influence of this weather.

In addition, there is the possibility of water leakage on the wall, and it will rain for a long time in winter, and the rainwater will seep into the wall, and the decoration of the indoor wall will be moldy and black, and in severe cases, there will be peeling.

By attaching the heated wall panel to the wall, the water in the external liquid state will not penetrate and the surface will not be wet. Second, it is a high-heat, resistant, low-heat capacity insulation material, which can effectively prevent wall leakage and heat absorption. Its surface temperature is close to that of indoor air, and because the walls are cold, it does not condense and does not cause moisture.

Restrain and mildew on the wall is usually caused by rain, rainwater soaking into the interior through the cracks in the wall or insufficient insulation on the exterior wall. In this case, the waterproofing of the exterior wall should be done in time.
