What should I do if mold grows on the wall of the room?

Question 1: What should I do if the room walls are moldy? Complete solution: shovel off the wall skin, make it waterproof, and then scrape putty and paint. Temporary method: Apply 84 disinfectant bleach solution to hair (brush several times) to lighten the color of mildew spots.

Question 2: What should I do if the wall at home is a little moldy? In the rainy season, the room is always wet and the walls are often moldy, which is the most worrying thing for many families. A large part of indoor humidity is related to indoor ventilation, but weather is also an important factor affecting indoor humidity. So what if the indoor wet wall is moldy? Don't worry. Today, Tianjin is the first to create decoration, so let's analyze the reasons and solutions for the high indoor humidity.

How to deal with damp and moldy walls of the house? There are ingenious ways to solve the damp and moldy walls.

The reason for the humidity in the room

No matter spring, summer, autumn and winter, as long as the indoor temperature is higher than the wall temperature, the wall may show signs of moisture. In fact, this is mainly because the insulation of the wall is not done well. Because the wall does not well separate the indoor temperature from the outdoor temperature, the temperature difference is very large, resulting in moisture and humidity. Of course, it depends on the weather. No matter how good the wall is, it can't be the best. When the climate is too humid, it will also have an impact on the room.

There are several possibilities for moldy walls:

1. When decorating, the wall is not completely dry, so we have to shovel it off and redo the wall in spring.

Next to the wall is the bathroom. This wall is not waterproof. If it is wet, waterproof the bathroom again.

The water pipe buried in the wall is leaking. Find the leak and repair it.

4. There is no insulation layer on the wall, so the warm indoor air will condense into steam when it meets the cold wall, and it can be added as an insulation wall if conditions permit. If not, you can apply a waterproof coating on the wall, which will have a certain effect after being diluted with two-component oriental rain rainbow.

What if the room is wet?

1, use dehumidifier. When the room is wet, desiccant and activated carbon can be used to prevent moisture and absorb moisture. Desiccant and activated carbon can be used. There are many desiccants specially used for moisture prevention and dehumidification in supermarkets, the most common ones are moisture absorption boxes and dehumidification bags.

2. Buy an air dehumidifier, which is like a vacuum cleaner. It can concentrate humid air together, and when the humidity turns into water in many cases. Air conditioning dehumidification. Household air conditioners generally have the function of dehumidification. However, it takes two or three hours for the air conditioner to adjust the indoor air humidity, and it will make people feel very cold indoors.

3. Dehumidify with lime and bamboo charcoal. Put a proper amount of lime in a small cloth bag, tie it into a small bag and put it in every corner of the room. Lime itself has the function of absorbing water, and can also slow down the indoor humidity. At the same time, lime also has disinfection function, killing two birds with one stone. Bamboo charcoal dehumidification can be used repeatedly, but it needs to be used more. Without it, the effect is not so good.

4. When the external humidity is high, doors and windows should be closed to prevent dampness and damp. Usually, more windows should be opened for ventilation to reduce indoor water vapor content. Especially in newly renovated houses, the humidity is particularly strong, and more ventilation is needed to eliminate the humidity.

6. When the indoor humidity is too high, if you don't use a computer or TV, you'd better make a protective cover to prevent the rear of the electrical appliance from touching the humid air. These appliances should be turned on often. The heat generated when the machine is running can effectively disperse moisture.

7. When the indoor humidity is too high, resulting in excessive humidity, it will lead to the phenomenon that the wet wall is moldy and hairy. When indoor mold spreads, it will have a very bad influence on people's health, especially those who are allergic to skin. So what if the room is damp and moldy?

8. When there is mold on the wall, you can first brush off the mold stains with a dry toothbrush, and then gently wipe them with a soft cloth dipped in alcohol, so as to dry the wall and prevent mold from breeding.

9. In addition, for the problem of moldy walls, bleach and water can be added according to the ratio of 1:99, mixed into a water agent, poured into a spray bottle and sprayed on moldy walls. If the weather is still wet, bleach and water can be mixed according to the ratio of 1: 20 and smeared on moldy walls. After the wall is dry, smooth it with sandpaper, then brush a layer of waterproof primer and finally a layer of latex paint.

Question 3: What should I do if the walls of my room are damp and moldy? I suggest shoveling off the large area, shoveling off the moldy part on the small area, leveling the putty, and then coating a layer of primer on the back cover.

Then make diatom mud. The effect is very good. An online emerging company basically guarantees that it will not be moldy from the aspects of mildew and humidity.

You can try.

Question 4: What should I do if the top of the room is moldy? 1. When mildew spots have appeared on the wall surface, you can brush off the mildew spots with a (dry) toothbrush first, and then gently wipe them with a soft cloth dipped in alcohol, so as to dry the wall surface and prevent mold growth.

2. Pour bleaching powder (powder) with water into the spray bottle according to the ratio of 1: 99 and spray it on the moldy wall, which can immediately solve the problem of moldy wall. Wipe the wall with a rag; Then wash it with clear water, dry it, and brush the mildew-proof paint on the wall to protect it from moisture for a long time. In addition, there is a convenient household waterproof repair agent on the market, which only needs to be sprayed on the gap of the leaking wall like an insecticide, so it is very convenient to operate.

When the mold is not too serious, it is enough to wash the wall with 80% alcohol. Pay attention to ventilation and wear protective gloves, masks and glasses when cleaning. In order to avoid mildew again, we should pay attention to thoroughly drying the walls, eliminating the causes of mildew, and properly heating and ventilating.

4. When the weather is wet, try to open the window as little as possible. In addition, try to make the wall dry. In wet weather, you can use dehumidifier, air conditioner and fan to absorb the water on the wall. Once there is water vapor on the wall or furniture, wipe it with a dry rag immediately.

Question 5: How to deal with the mildew spots on the walls in the room? It's too humid in the room. Be sure to open the window for ventilation. Paint moldy places, polish them with sandpaper, and change them with posters. But be sure to open the window for ventilation.

Question 6: What if there are black mildew spots on the wall? After spraying water with 84 disinfectant, it can not only kill the virus, but also bleach it, with remarkable effect.

In addition, pay attention to keep the bathroom dry and ventilated, and do not form a humid environment.

Question 7: The walls of the room are moldy in a large area. What should I do first? Wash it with oxalic acid, open the window for ventilation, and eliminate indoor moisture.

Question 8: What if mold grows on the wall? This is especially easy to appear in newly renovated rooms.

Many people think that the mold on the wall can be solved by wiping it off with a rag or repainting the wall, and some people use alcohol to remove it. In fact, these are all wrong ideas, which can only be temporarily eliminated or covered up, but not completely eliminated. After a while, mold will appear again and become more and more serious. Because wallichia is a kind of flora with strong vitality, the propagation mode of mold is divergent spores, which will grow in other places after being killed in one place. If the environment in which it grows is not completely destroyed or its flora is killed, it will multiply and spread rapidly when it meets the corresponding environment. Therefore, if you want to completely remove the wall mold, you can only take the following two methods:

1, select high-quality building materials to rebuild the wall. One is to do heat preservation from the inner wall, which not only destroys the decoration of the room, but also has a short effect. Many owners will not recognize it, and even go to court for room decoration and property compensation; The other is to use high-quality materials from the external wall to make waterproof insulation layer. This method is completely solved, but the external walls of buildings have to be redone, which not only takes a long time to construct, but also costs a lot, which is unbearable for many companies. At present, the built buildings are rarely used.

2, using the wall mold scavenger:

Before use, please shake this product evenly, spray it with ordinary air pressure, make it into fog, and spray it directly on the mold on the wall. The mold will decompose naturally within 30 minutes, and the wall will return to its original color, leaving your room as clean as ever.

Question 9: What should I do if the wall of the renovated house is moldy and stained? I really don't know if the wall is moldy. The walls are moldy. First, the weather is humid, and the wall is not dried in time because of wet water seepage. Second, the paint is not dry on the wall, because the glue is easy to get moldy when mixed together, which leads to moldy walls. Both of these reasons have a high probability of mildew on the wall.

1, moldy degree: Method 1: When mildew spots have appeared on the wall surface, you can brush them off with a (dry) toothbrush first, and then gently wipe them with a soft cloth dipped in alcohol, so as to dry the wall surface and prevent mold growth. Method 2: It is enough to wash the wall with 80% alcohol. Pay attention to ventilation and wear protective gloves, masks and glasses when cleaning. In order to avoid mildew again, we should pay attention to thoroughly drying the walls, eliminating the causes of mildew, and properly heating and ventilating.

2. The degree of mildew is serious: first polish it with sandpaper, and if there is delamination, smooth it with a shovel; Then, if the wall is uneven, it needs to be repaired with putty; Finally, if the wall is flat, it is recommended to brush the sealing primer first and then the latex paint.

Question 10: What should I do if the old house climbs alkali? After a while, the walls will be moldy and the house will smell moldy. How to deal with:

1, when a small range of mildew spots appear on the wall, you can brush off the mildew spots with a (dry) toothbrush first, and then gently wipe them with a soft cloth dipped in alcohol, which can dry the wall and prevent the growth of mold.

2. Pour bleach (powder) and water in the ratio of 1: 99 into the spray bottle and spray it on the moldy wall to solve the moldy problem of the wall immediately.

Wipe the wall with a rag; Then wash it with clear water, dry it, and brush the mildew-proof paint on the wall to protect it from moisture for a long time.

3. In the case that the wall is moldy in a small area, it is enough to wash the wall with 80% alcohol. Pay attention to ventilation and wear protective gloves, masks and glasses when cleaning. In order to avoid mildew again, we should pay attention to thoroughly drying the wall, eliminating the cause of mildew and heating and ventilation correctly.

4. When the weather is wet, try to open the window as little as possible. In addition, make the wall as dry as possible. In humid weather, dehumidifiers, air conditioners and fans can be used to absorb water from the wall. Once there is water vapor on the wall or furniture, wipe it with a dry rag immediately.
