What to do with mold on the wall, what to do if there is mold on the wall

The mold spores visible on the walls can be wiped with a sponge dipped in diluted bleach, or a little white vinegar or lemon juice can be dropped in warm water to become a natural mold remover.

If your clothes or bags are contaminated with mold, you can add 1 small cup of lemon juice and 1 small cup of salt to 1 gallon of hot water, wipe with a cloth to remove mold, remember to wash it outdoors in a ventilated area.

Please open windows and wear gloves or masks when cleaning to avoid allergic reactions.

During the wet season, use an air conditioner and dehumidifier.

The home should be well ventilated. It is best to install ventilation fans in the kitchen and bathroom.

Maintain a stable indoor humidity. It is best to keep the humidity below 40 degrees to prevent mold from developing.

If mold continues to grow after removal, it may be a problem with water leakage. Inspect water lines, ceilings and floors and have them repaired. Beg.

The root cause of wall mold is dampness, what is the cause of dampness on the wall? Generally speaking, there are three types of conditions that cause dampness on the wall.

1. Leakage of drainage pipes or heating pipes causes the wall to be damp, and the wall will become moldy after a long time. 2. Cracks in the wall, external rainwater, etc. seep into the room through the cracks, resulting in dampness of the wall. Poor sealing of balconies and windows may lead to rainwater seeping into the room.

3. The wall insulation is not done well, resulting in a large temperature difference between indoor and outdoor, so that the water in the indoor air will condense to the wall after being cold, resulting in dampness of the wall and mildew on the wall. Only by prescribing the right medicine for various situations can we solve the problem of hair caused by dampness on the wall. Most people know that the problem of mold on the wall is caused by moisture, and they generally use a waterproof layer to strengthen the wall to solve such a problem.

Actually, this is not a problem. Conventional waterproof layers, waterproof coatings, etc. are for liquid water, such as rainwater, the waterproof layer can indeed play a certain role in preventing water from seeping into the wall and causing the wall to be wet. However, dampness on the wall is more often caused by condensation on the wall.

Condensate can condense on the wall because the wall is cold, the surface temperature is much lower than the indoor air temperature, and the water vapor is easy to condense on the wall, forming condensation, which leads to dampness on the wall. For example, if you take out a bottle of ice water from the refrigerator in the summer, a large number of water droplets will appear on the surface of the bottle after a while, and the condensation on the wall will form the same reason. In this case, waterproofing the wall alone will not solve this problem.

And this reason leads to damp and moldy walls, which often occur more often in winter. These all show that the main reason for the damp and moldy walls at home is actually the failure to do a good job of wall insulation. I don't know if anyone touches the wall of the home with their hands during the winter heating, if so, you will find that even if the heating equipment is turned on for a few hours, the indoor wall is still cold, that is because the wall is seriously leaking and absorbing heat.

After the cold wall comes into contact with the warm air indoors, the huge temperature difference will create a thermal bridge, which will cause condensation, dampness and even dripping on the interior walls of the house, and slowly the damp walls will become moldy. Therefore, solving the problem of damp and moldy walls caused by indoor temperature difference cannot be solved by a waterproof layer. The waterproofing layer only protects against liquid water, not water vapor.

The resurgence caused by water vapor erosion of the wall can lead to mold on the wall over time. The heating wall panel is pasted on the surface of the wall, firstly, the external liquid water can not penetrate through, and the problem of surface dampness will not occur, and secondly, this is a thermal insulation material with high thermal resistance and low heat capacity, which effectively blocks the heat leakage and heat absorption of the wall, and its surface temperature is close to the indoor air temperature, and will not produce condensation and cause dampness because of the cold wall. Therefore, no matter which situation causes the problem of dampness and mildew on the wall, there is an obvious solution effect.

First of all, it is necessary to check whether there is leakage on the wall, confirm that there is no leakage before entering the next process, brush the interface agent on the blank wall, and then treat the cracks on the wall, after treatment, the straightening of the yin and yang angles includes the wall leveling, that is, the batch of embedded wall cracks are more, to paste the cloth, the condition can be used grid cloth, relatively speaking, the anti-crack will be better, and then the putty on the wall batch 2 to 3 times, after the putty is dried, polish with sand, be sure to polish the side light, and find that the defects must be repaired. Finally, use a primer with a little more water to roll it over, so as not to have color difference when painting the topcoat due to the difference in draught from other walls. After drying, you can brush the topcoat twice, and pay attention to the maintenance during the drying of the topcoat, although the latex paint will generally dry within 4 hours after brushing, but the dry paint film also slips to a certain hardness, so do not have any scrubbing or contact with the wall within a week.

It's damp. Let's get it all over again. If it is infiltration from the outside of the wall, you can find out the problem of infiltration and solve it before making it inside.

What should I do if my walls are moldy?

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.

First of all, it is necessary to find the cause of the dampness of the wall, and if it is caused by water leakage, it is necessary to find a master to deal with it in time. If it's because of the weather, here are a few things you can do: Intermittent ventilation:

Afternoon is the best time to close the doors and windows facing south or southeast on rainy days to reduce moisture entering the room. At noon, the air humidity outside is at the highest value, and it is not appropriate to open the window, so it should be opened in the afternoon or evening, when the climate is relatively dry, open the window to adjust the indoor air. Lime moisture absorption:

On rainy days, you can wrap quicklime in cloth or sacks and place it in various places indoors to keep the indoor air dry. Air conditioner dehumidification: It is simpler than the previous two methods, but it consumes electricity, so it is recommended to use other environmentally friendly and moisture-proof methods to save energy.

Practical moisture-proof small objects Moisture absorption box: a must-have for wardrobe dehumidification. The more common hygroscopic products on the market are generally made of calcium chloride granules as the main content, and most of them also add flavor ingredients, so they integrate functions such as dehumidification, aromatherapy, mildew resistance, and deodorization.

Moisture absorber boxes are mostly used for moisture absorption in wardrobes and shoe cabinets. To use it, simply put it in the cabinet. Moisture Absorbent Pack:

Confined spaces work best. The principle of the hygroscopic bag is similar to that of the humidity absorbent box, but the contents are mainly water-absorbing resin, and after absorbing water, it becomes jelly-like and is not easy to disperse into pieces. In addition to clothing, leather goods, stamps, cameras, pianos, computers, audio-visuals, etc. can be used to help dehumidify.

If placed in a confined space, the moisture absorption effect is better. The way to solve the problem thoroughly: shovel off the wall skin, do waterproofing, and then scrape putty to brush the paint.

Temporary method: Use 84 disinfectant bleach solution and apply it to the moldy area (you can brush it several times) to lighten the color of the mold. The above methods are for reference only, you can choose the right dehumidification method for your home.

If the mold on the wall is not serious, then you can use sandpaper to polish it first, and then use 84 disinfectant or alcohol to disinfect the wall, and wipe the wall with a towel dipped in alcohol.

If the mold on the wall is serious, after cleaning the wall, the wall can be waterproof and moisture-proof, such as coating a layer of waterproof paint on the wall, which can effectively prevent and control the mold on the wall.

Causes of moisture on the walls:

1. The large temperature difference between indoor and outdoor may be due to the fact that the wall insulation is not done well, resulting in a large temperature difference between indoor and outdoor, and the water vapor in the indoor air is pre-condensed to the wall, which will lead to dampness of the wall for a long time.

2. Leakage of water supply pipes and drainage pipes, and leakage of pipelines will lead to dampness and mildew of the wall for a long time.

3. Rainwater infiltrates into the room, and this situation occurs because the junction between the baffle under the balcony window and the wall is not properly treated, cracks appear, or the sealing of the window is not strict, resulting in rainwater seeping into the room and causing the wall to become moldy.

1. For simple moldy walls, it is recommended that when the weather is dry, you can use a vacuum cleaner with a brush to suck while brushing, and you must not wipe it with a damp cloth. 2. You can use the household convenient waterproof repair agent to spray it on the gap of the leaking wall and ground, which is very convenient to operate. 3. If the mold is not too serious, you can use a dry toothbrush to brush away the mold stains first, and then use alcohol to scrub the wall.

Pay attention to ventilation when washing, and wear protective gloves, masks and glasses.

Reasons for this problem:

1. The wall insulation is not done well, the temperature difference between indoor and outdoor air is large in winter, and the phenomenon of condensation will generally occur on the wall.

2. Maybe the air in the house is too humid, and the walls slowly start to mold.

3. The wall may be damp due to pipeline leakage, and it will start to mold after a long time.

4. If the wall cracks or the balcony window is not well sealed, the rainwater will soak into the room, which will cause the wall to be damp and moldy.

5. The moldy head of the wall is very ugly, and the moldy wall will emit mold spores, which is very harmful to the human body. Moreover, once the mold spores flow in the air, they can easily enter the human body and invade the respiratory system, and multiply rapidly. Long-term exposure to mold can cause respiratory diseases and allergies, and some people with low immunity may also feel unwell.

How to deal with the moldy wall, 1. If there is less mold, you can use a dry tooth source dry plum brush to brush off the mold, and then wipe it with a cloth dipped in alcohol; 2. If there are many moldy parts, you can pour bleach into the watering can, then add water to dilute, then spray on the moldy place, then wipe with a rag, wash with water, and finally brush with anti-mildew paint after hail; 3. If the mold is very serious, you can only ask a professional to deal with the mold and then repaint the wall; 4. Pay attention to ventilation and ensure that the humidity of the room is not too large.

In our daily life, mold on the wall is a relatively common phenomenon, sometimes because of the dampness in the house, so it often leads to water accumulation in the corners, if it is accumulated for a long time, in this case it will cause mold on the wall. Let's introduce to you how to deal with the moldy wall.

1. When the wall has been appealed, you can use a brush to wipe it, and then use a clean cotton ball to dip it in alcohol, and then wipe the wall to keep the wall dry. At the same time, it is also necessary to do regular inspections, and when it is found that it is moldy again, it is also necessary to deal with it in time.

2. When the moldy area is relatively large, you can use a brush to dip a large amount of alcohol at this time, with a concentration of almost 80%, paint the surface of the wall in large quantities, and then dry it, and if you have a hair dryer, you can dry the wall.

3. When most of the wall has become moldy, you can also choose the most convenient way. That is, you can use a mold removal solution mixed with water, and then paint a large area to the entire wall. Then open the window for ventilation, be sure to ensure fast drying.

It can be said that this method is relatively suitable for the case of a lot of mold, after the treatment, paint the wall, this is also to ensure that the humid environment is isolated.

4. In the case of humid and rainy weather, the doors and windows should be closed in time for it, at this time, if you find that there is a damp phenomenon on the wall, then you should immediately wipe it with a dry rag, and then dry it with a hair dryer.

5. When you are clear about the stubborn mildew, first of all, you should use gauze to polish the moldy place, and then use a shovel to shovel off the moldy place, and spray the mixture of solution and water.

Summary: How to deal with the moldy wall is introduced here, you can take the above ways to deal with the moldy situation of the wall, different phenomena use different methods, I hope the above introduction will be helpful to you.

There are several ways to deal with mold on the wall:

1. When the mold of the wall is not serious, it can be wiped with a damp cloth or washed, and if it cannot be completely removed, it can also be cleaned with bleach, so that the mildew can be removed.

2. When you can't clean the mold on the wall with clean water, it's best to scrape off the mold on the wall and brush it again.

3. What should I do to prevent the wall from becoming moldy again in the later stage? It is recommended that you still brush a layer of waterproof paint, latex paint, etc. on the wall, so that you can do it once and for all, and then you don't have to worry about this problem in the future!

4. Finally, I remind everyone that in order to prevent the wall from becoming moldy, it is best to recommend that you always ventilate the room and maintain a clean and tidy environment, so that the indoor wall will not mildew, and you don't have to worry about it anymore.
