What causes mold in a large area of the ceiling?

There are several reasons for mold on the ceiling:Reason 1: If the ceiling and the outdoor cement are not firmly jointed, the rainwater will enter the room through the cracks, so there will be dampness, mold, hair, etc. around the window.

Reason 2: When the living room is decorated, part of the waterway is improved to the inner wall, and the water pipe embedded in the ceiling has leakage, resulting in damp and moldy ceiling.

Reason 3: Poor air circulation in the room, resulting in excessive indoor humidity, humid ceilings and their easy adhesion to the indoor air containing nutrients in the floating matter, mold.

Dampness is the main cause of mold. On southerly days, the air humidity is very high, and the walls and ceilings are prone to condensation, causing dampness and slowly causing mold. In this case, it is advisable to strengthen the interior wall insulation by using a dynamic insulation wall panel to prevent the formation of a damp environment, which may be a leak or seepage of the house.

After a long time, it will naturally become moldy and black.

It may be that the paint is fake, and many poor paints are absorbent, and the humid air in the air is absorbed into it, and it cannot be dried for a long time, so it will be black and fall off.

The fumes in the house cannot be discharged. We used to be in our rural hometown, and the ceiling of the new house would be dark within two years. The main reason is that cooking in rural areas is mainly based on firewood, and there is no smoke exhaust equipment installed in the house.

Under normal circumstances, there are usually more water droplets on the ground floor than on the upper floors when the weather is back to the south. In this kind of weather, try to open the doors and windows as little as possible, you can turn on the air conditioner Whether it is heating or cooling, there is a dehumidification function, and most of the air conditioners have a moisture removal function, and special moisture removal can also be carried out.

The mechanism of this phenomenon is due to the movement of air. When the bulb is working, it will emit heat, which leads to the convection of the surrounding air, the air with a high flow rate will carry more dust, and the place where the air flow has been impacted for a long time will accumulate more dust than the surrounding area, waterproof coating or cement-based crystalline penetrating waterproof coating, of course, polypropylene waterproofing can also be used.

It is easy to mold at the junction of the wall and the roof. This location is commonly found at the junction of the wall and wall of our exterior windows. This type of roof is moldy and is common in many parts of the south.

And generally after the autumn, due to the large temperature difference between the inside and outside, or a small area of local water leakage slowly leads to the appearance of mildew, generally mildew appears in the corner, top surface, balcony and other places, mainly there is no brick place, generally brush the top surface of the wall with latex paint This phenomenon occurs more.

Newly moved houses or houses that have been lived in all the time will have a large area of mold on the ceiling, especially in wet and rainy days, which will affect the beauty of the house, so what is the cause of mold? Let's discuss it together.

1.A large area of mold on the ceiling is likely to be caused by renovation. Because there are certain nutrients in the interior decoration materials, such as a certain amount of cellulose in Dabai, the sugar in the cellulose will develop under a certain humidity and temperature, and then it is easy to cause mold.

If the renovation is done without the ceiling drying out, then the moisture will be trapped in the wall, which will cause a large area of the ceiling to mold, causing mold spots. The application of inferior interior decoration materials is also easy to cause mold at a certain humidity.

2.During the rainy season and when it is wet, the home will be relatively humid, and the roof is prone to water seepage, which can easily produce mold, resulting in a large area of mold.

3.Wall quality issues lead to moldy ceilings. The exterior wall brick inlay is not solid, and the brick joints are not filled or the joints are selected; The mortar of the outer filling wall is not full, there are sand holes, gaps, and cold and hot bridges are generated; The junction between the wall and the beams and columns is not densely filled, and cracks are prone to occur; When the doors and windows are made, the foam filling is not dense and there are gaps.

There are also cracks in the wall, and some water seepage is also the reason for the dampness and hair of the internal and external walls.

4.The waterways cause mold in the ceiling. When decorating the living room, improve the internal and external walls of a part of the waterway, and there is a leaking area of the water pipe embedded in the ceiling, which causes the ceiling to be damp and moldy. This is also the cause of mould on the ceiling in the room near the bathroom.

5.Waterproof is not good. The ceiling is waterproof and leaking, resulting in a lot of damp hair on the ceiling. Or the original ground waterproofing has been damaged in the renovation and transformation, and the water gradually seeps from the high-rise, and the bottom ceiling has black spots and mold.

6.Check the temperature in the room, under normal circumstances, the body feels the most comfortable temperature, at the same time, it is also a greenhouse where mold is easy to grow and develop, this is not easy to change, and at the same time, if the humidity is higher than 80%, it is also easy to cause mold, but if the humidity is low, people will feel uncomfortable, it is difficult to have both.

First of all, what we have to do is to check whether there is water seeping out of the ceiling or corner of the house, and find the cause of the mold on the ceiling. The large area and relatively uniform mold is likely to be caused by improper decoration, and the ceiling mold treatment method is as follows:

1. When mold is found, it is important to remove them quickly. Quickly clean up the mold and address the root cause of the problem before it affects your health or causes sexual damage to your home. It's easier to clean up as soon as possible, and it's less likely that the ceiling will get moldy again.

2. Check the ceiling building materials. If the ceiling is made of porous materials, such as popcorn ceilings (paper, styrofoam or asbestos), wood, gypsum board, etc., it cannot be cleaned. Mold will soon grow again.

You'll need to remove the affected ceiling and reinstall a new one. Porous ceilings, including popcorn ceilings, need to be removed and reinstalled to address the mold problem.

3. Use a paint scraper to scrape off the paint. If the ceiling has ever been painted, but the paint is starting to peel off, you should first use a scraper to remove the remaining debris. Make sure there is no mold under the debris before you can clean them thoroughly.

4. Wear gloves to protect your hands and change into old clothes. Wear gloves to protect your hands from contact with detergents and mold. Wear old clothes that can be washed in hot water to remove spores that fall on your body or spread through the air.

5. Prepare mold removal solution. Many solutions can remove mold. The most commonly used solution is 2 tablespoons of borax, 60 ml of vinegar and 480 ml of hot water, which not only kills mold and deodorizes, but also reduces the likelihood of mold regrowth.

Moisture is the main cause of mold. When the south wind blows, the air humidity is very high, and the walls and ceilings condense, which is easy to cause moisture and mold. In this case, it is advisable to use dynamic insulation wall panels to strengthen the insulation of the inner walls, prevent the formation of a humid environment, and prevent the walls from becoming moldy.

The first thing to do is to check the exterior walls of the room for water infiltration. The other is whether there is a water leak in the upper floor of your house, allowing the water to seep into the corner of your house. Ask again if the previous room has been renovated and if there are any oil stains on the walls.

There are these things at the bottom of the wall, and when you encounter moisture when you don't clean it, it will appear what you said. David Asher, to find the root cause that needs to be addressed. Otherwise, even if it is repaired in a hurry, it can only be managed for three to five days.

Find the reason and then deal with the paint workers, the workers know what to do, and pay attention to it when renovating. John kennedy.

There are two possibilities. One is water leakage, and if it leaks, the water flows to a low place, so you can't see the water upstairs, and it's normal for the downstairs to get wet. The second may have moisture, and it is more common for water in the air to condense in square corners!

Although there is no construction, it is possible to provide professional technical consultation for hands-free concrete waterproof leakage repair. Now those construction workers are always cutting corners, which we often see.

The design of the ceiling of the living room and the feng shui issues in the decoration should not be ignored. The living room is the place where good feng shui protection is most needed, and therefore it is related to the fortune and health of family members. Is there anything to pay attention to on the ceiling in the living room decoration?

Follow me to find out. I didn't know you were the house from a few years ago. There may be water pipes in the ceiling of the current house structure.

That depends on the structure of your home, the layout of the bathroom, or whether your home is Yang Wei. When living on the ceiling, an electric drill can penetrate the water pipes.

All in all, there are many cases of mold in the living room, and there are many reasons, it is necessary to comprehensively consider the situation upstairs, and environmental factors, if the cause of water leakage is excluded, it can also be solved by strengthening ventilation and ventilation.

It may be that the house is too damp or that there is a water leak in the house. If the roof waterproofing is not done well, it will lead to rainwater infiltration, and the ceiling will become moldy after a long time.

It may be due to the weather, which happens to be in the rainy season, and the air is relatively humid. The roof is not waterproofed, the indoor humidity is relatively high, and the ceiling is prone to mold, which breeds a lot of mold. It is necessary to do a good job of dehumidification indoors in time to prevent the home from being too damp.

It may be that the dampness in the home has caused this situation, or it is possible that there is a rain leak on the ceiling, which causes the ceiling to become moldy, and you can observe what the cause is.

It is very likely that the whole environment is relatively humid, or it is also possible that the people on the floor often sprinkle water, so the water seeps down.

Because there is water seepage, you can check whether it is rainwater seeping into the exterior wall or water seepage caused by improper water use on the upper floors.

It may be caused by the humidity at home, or it may be caused by the humidity at home, or it may be caused by the dark environment at home, or it may be caused by the air environment at home is not very good, or it may be caused by the temperature at home is relatively hot, all of which may lead to mold at home.

The decoration is not done well, the rain is too heavy and the house becomes damp and easy to mold, the quality of the wall is problematic, the ceiling is not waterproofed, and it may also be because of the sewer.

It may be that the house is too damp, it may be a water leak, it may be that the sun is not shining enough, the house is too cloudy, or it may be that the usual cooking has brought gas to the house.

Large areas of mold on the ceiling are likely to be caused by renovations. Because interior decoration materials contain certain nutrients, such as the White House contains a certain amount of cellulose, and the sugar in cellulose is easy to produce mold at a certain humidity and temperature. If the ceiling is not completely dry, moisture can be sealed in the walls, resulting in large areas of mold and mildew on the ceiling.

Secondly, due to the combination of ceiling and outdoor cement, there is more rain in summer, and rainwater will enter the room through the gaps, causing dampness around the windows, which is easy to mold after a long time. If there is mold on the ceiling near the bathroom, it is likely to be caused by the water pipes, because during the interior decoration, some water pipes will improve to the inner wall, and the embedded water pipes in the ceiling will leak, resulting in a large area of mold on the ceiling.

In the rainy season, when it often rains, when it is humid such as returning to the south, the home will be more damp, and the roof is easy to breed mold, which is easy to seep water, causing a large area of mold. Check the temperature in the house. Generally speaking, the most comfortable temperature for the human body is also a greenhouse that is prone to mold growth.

It's not easy to change. At the same time, if the humidity is higher than 80%, it is prone to mold. However, if the humidity is low, people will feel uncomfortable, and it will be difficult to achieve both at the same time.

The ceiling is not treated with anti-mold, and the moisture on the walls is not dried in time, making the walls damp and easy to breed mold. Because the humidity of the environment where mold grows is exactly what the human body hates, it is difficult to regulate. When the sun is shining, you should always open the windows to breathe and keep the indoor air transparent.

In rainy weather, the air conditioning mode can also be adjusted to dehumidification mode to reduce indoor humidity, ensure human comfort, and inhibit the generation of mold.

Check the roof, wall and ground of the house for water seepage in time. Once there is, it should be renovated in time, especially on rainy days, when rainwater will come in and the floors of the upstairs residents will leak to keep the walls dry. Spray special release agent for demoulding in time, and carry out anti-mildew treatment on the wall, so that the wall forms a protective film and protects the wall more carefully.

It is likely to be caused by the humid environment at home, the quality of the ceiling is not good, the moisture-proof effect of the ceiling is not good, and it is likely to be caused by a long period of rainy weather.

It may be because the ceiling is so damp, so this phenomenon occurs, and it is also possible that there is a leak in your home, so it will become moldy.

It is caused by too much moisture in the home in ordinary life, and a lot of water appears on the ceiling through evaporation, and the quality is not particularly good, so it is easy to mold.

1. The joint between the window and the outdoor cement causes the rainwater to enter the room from the cracks, causing the dampness around the window, and the mildew and hair grow over time. 2. Interior decoration materials contain a certain nutrient base, such as: Dabai contains a certain amount of cellulose, and the sugar in cellulose is easy to produce mold at a certain temperature and humidity; Decoration before waiting for the wall to dry and enclose moisture in the wall will also cause the wall to become moldy and hairy; Inferior interior decoration materials are used, which are prone to mold under a certain temperature and humidity.

3. The quality of the exterior wall leads to mold on the wall. The exterior wall brick inlay is not solid, and the brick joints are not filled or the joints are filled; The outer filling wall is not full, and there are trachoma and gaps, forming a cold and hot bridge; The junction of the wall and the beam and column is not densely filled, resulting in cracks; When the doors and windows are installed, the foam filling is not dense and there are gaps. There are also cracks in the exterior wall, and local water seepage is also the cause of damp hair growth on the interior wall.
