How mold is formed on the wall and how to deal with mold on the wall

The main reason is that the house is damp, the moisture is too heavy and the ventilation is not ventilated. (Or it's too cold outside, and it's hot and poorly ventilated inside, and it may grow this thing).

Normally, mold is mostly found outdoors, but mold spores can enter the house when you open an open door or window. As long as the conditions are right, mold can be in anyone's home. You may not be able to see the mold spots they grow on the walls, but they do exist indoors.

Mold growth requires two conditions, one of which is humidity. In an environment with a relative humidity of more than 50%, as long as there is continuous water (such as leaking water pipes in the home), it is possible to make the local relative humidity high, resulting in the survival of mold. The second is where it grows.

Mold tends to grow on planks, wood, or fibers, but mold is very active and can live almost anywhere.

Molds reproduce by producing spores, which are air-transmitted. Mold spores can fall and grow in house dust and are part of the house dust. House dust containing mold spores can cause allergic symptoms if inhaled into the airways by a person who is allergic to mold.

If this situation only occurs in winter, it is mostly a problem of the house, your house insulation is too thin or there is no insulation, and it will condense on the interior wall when it freezes through in winter, just like condensation on glass. To solve the problem completely, insulate the wall where the problem occurs.

In fact, bacteria are everywhere, as long as there are suitable conditions, they will multiply in large numbers, according to the most suitable growth conditions for different bacteria, the composition of the medium, the culture conditions are different, bacteria can be cultivated.

Mold on the walls is become.

Wall cancer. It is a kind of water leakage phenomenon, and it is also a phenomenon in the process of deterioration of cement products, which is called in academics.

Bai Hua. Phenomenon. When the cement wall is eroded by water vapor, when the water vapor enters and exits the cement crevice cracks, acid-base neutralization occurs to produce carbonate.

Crystals. when it silts up the walls, thus caused.

wall paints. Wallpaper blistering, bulging, chipping, peeling and other phenomena. The occurrence of wall cancer means that the humidity in the air is very high, and the environment is humid, and it is easy to breed bacteria.

Morphology and smell:

If the wall is moldy, mold will grow on the wall, and some of these wall molds will form black spots on the wall, one by one, some will grow more luxuriantly, and one large piece will even spread to the entire wall. The smell of the wall where mold grows is pungent, producing a "wrapping smell" similar to that produced by steamed bread mold.

The smell is actually the smell of spores released by wall mold in the air. The composition of wall mold is complex, most of them are toxic, and long-term inhalation of these spores is very bad for human health.

Every year in June and July, the rainy season begins, and there is a proverb that says; "The rain hits the yellow plum head, and there is no sun on the 45th" to describe the plum rain, it can be said that the rain continues to be continuous, and the temperature, high humidity and humidity are the main characteristics of the plum rain. The rainy season makes people feel that the quilt and clothes seem to be able to wring out the water in minutes, not to mention the moldy walls of the home.

What should I do if the wall is moldy? A few common wall problems to share with you.

It must be treated with a material with strong permeability done from the mortar layer.

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, except for us, there are few domestic research and development in this direction.

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.

Tips for removing mold from your walls:

Many people think that the wall has mold, and it can be solved by wiping the mold with a rag or repainting the wall, and there are also those who use alcohol to remove it, but in fact, these are wrong ideas, which can only be temporarily eliminated or covered, not completely eliminated, and after a period of time the mold will appear again and become more and more serious. Because wall mold is a highly viable flora, mold reproduces by diverging spores, and when killed in one location, it will also grow elsewhere. If the environment in which it grows is not completely eliminated or its flora is killed, it will multiply and spread rapidly in the corresponding environment.

Therefore, there are only two ways to completely remove mold from the wall:

1. Use high-quality building materials to redo wall transformation. One is to do thermal insulation from the interior wall, this method will not only destroy the decoration of the room, and the effect is not long-lasting, many owners do not recognize, and even will go to court with the property for the compensation of the decoration of the room; The other is to make a waterproof insulation layer from the exterior wall with high-quality materials, this method solves thoroughly, but all the exterior walls of the building have to be redone again, not only the construction time is long, and the cost is very huge, many companies can hardly afford it, and the buildings that have been built are rarely used.

2. Use Qingli wall mold remover, please shake this product well before use, use an ordinary air pressure watering can, adjust it into a fog, spray it directly on the wall mold, and the mold will naturally decompose within 30 minutes, and the wall will be in its natural color, so that your living room is as clean as ever.

Precautions: 1. Please stay away from the fabric when spraying, so as to avoid the items being oxidized and discolored. Spray directly on the wall mold.

2. If the wall has peeled, layered or wall powder, it is best to scrape it off and then spray this product, and then scrape the white or latex paint (no material and beautiful).

3. When spraying, expand a few centimeters outside the mold, so as to better kill the mold spores and the growth environment of the mold.

4. If the wall is a high-grade waterproof latex paint (the kind of water sprayed on the wall does not penetrate and flows downward, there are not many such good waterproof latex paints, but there are very few ones), it is best to scrape off the waterproof layer on the surface and then spray the wall mold to make the product fully penetrate and play a role.

1. You can use alcohol or 84 disinfectant to treat the mold on the wall, it is best to wipe the mold with a rag first, do not use a brush directly, otherwise the mold will be scattered into the air. 2. If there is a lot of mold, you can wipe it clean with alcohol, and then spray it on the moldy wall with bleaching powder and water according to the proportion. 3. When dealing with the mold on the wall, pay attention to wearing masks and goggles, open the window for ventilation in time after the treatment is completed, and wait for the wall to dry thoroughly.

1. Pay attention to opening more windows for ventilation, and don't let the indoor air be too humid, which will also breed the growth of mold. After disinfection, if the ventilation effect of the window is not good, you can also use a hair dryer or dryer to dry the wall, which can make the wall dry faster.

2. During construction, it is necessary to do a good job of waterproofing the wall to prevent water seepage on the wall, which can effectively achieve the purpose of preventing mold in the wall.

3. Check the water pipes at home regularly to see if there is leakage, if the water pipes leak, it may also cause mold on the wall.

4. In the rainy season, if the sealing effect of the window is not very good, the surrounding environment will be relatively humid, and mold will also grow.

1. It may be that the temperature difference is large, and the insulation layer of the wall is not done well, which causes the indoor water vapor to condense to the wall, which will cause the wall to become moldy after a long time. 2. It may also be caused by rainwater infiltrating into the room, which occurs because there is a gap between the window and the wall, or the sealing of the window is not good, resulting in rainwater seeping into the room. 2. If the mold on the wall is not very serious, you can use a dry brush to remove some mildew spots on the wall, and then use a cloth dipped in some alcohol to wipe the wall clean.

Relevant knowledge development materials: 1. The mold of the wall is caused by the humid weather, and some anti-mildew paint can be brushed on the wall, which can prevent the wall from being damp and mildew. You can also turn on the dehumidification function of the air conditioner, or consider putting some activated carbon in the room to absorb moisture.

2. If the wall is moldy and the wall is not waterproofed, it is still necessary to ask someone to do the waterproofing, or to repair the leaking drainage pipe, and then brush some putty, latex paint, etc., and there is a possibility that the sealing of the window is not good, you can seal it with glass glue, etc., and then use alcohol to remove the mildew on the wall.

1. When the wall has mildew, you can use an old toothbrush to brush off the mildew stains, and then gently wipe it with a soft cloth dipped in alcohol to dry the wall, which can effectively prevent the growth of mold. 2. You can also use bleaching powder and water, mix it up in a certain proportion, pour it into a spray bottle and spray it on the moldy wallpaper, which can solve the problem of mold on the wall. 3. In the case that the mold is not too serious, it is enough to use 80% alcohol to wash the wall.

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

1. In order to avoid mold again, we should also pay attention to the thorough drying of the wall, and the elimination of mold requires correct heating and ventilation. Open windows as little as possible during wet weather. Wipe the wall with a rag, then wash it with water, and brush the wall with anti-mildew paint after drying, which can also be moisture-proof for a long time.

2. The cause of mold on the wall: the drainage pipe or heating pipe leaks, which causes the wall to be damp, and the wall will become moldy after a long time. Rainwater from the outside can cause dampness in the walls.

Cracks in the junction between the baffle and the wall under the balcony window, or poor window sealing, can cause rainwater from the outside to seep into the room.

3. If the wall insulation is not done well, it will also cause a large temperature difference between indoor and outdoor, so that the water in the indoor air will condense on the wall after being cold, which will also lead to dampness and mildew of the wall.
