What should I do if the roof of the penthouse is moldy? What should I do if there is mold in the cor

There are three necessary prerequisites for moldy ceilings: the right temperature, humidity above 80, and mold spores. Eliminating any of the premises will not become moldy.

Look at the temperature first, the temperature that the human body feels comfortable is also the temperature at which mold grows, there is no way, it can't be changed;

Look at the mold spores again, very small, fluttering in the wind, doors.

The window can't stop it, and he can easily enter your room.

It can't be eliminated either;

Finally, there is the humidity, which he needs above 80, which is exactly the humidity that we hate, and there are now many ways to reduce the humidity without causing us discomfort.

When the sun is shining, open the windows and let in a lot of air.

It's raining, it's a damp day, close the windows and turn on the air conditioner.

Turn to dehumidification mode. In summer, you don't have to worry too much, as long as the air conditioner is turned on, the humidity will naturally drop, and sometimes you need to add some water to volatilize.

Wardrobe. The door should be like a refrigerator.

Again, close a little tighter, and then put some desiccant.

It is also important to check the ceiling, walls and floors of the house.

Whether there is water seeping in, you should think about putting an end to it.

With these measures in place, you can say goodbye to mold.

There is also the use of professional wall mold remover, which can completely kill wall mold in a short time, and at the same time, it can also change the wall structure of the corresponding part to prevent the growth of wall mold.

That's the roof leaking and leaking, you have to re-waterproof the roof, the permanent way is to knock on the roof of the roof tiles.

The reason is very simple, it is because the ventilation is not good, and it is OK to find a way to ventilate.

1. Shovel the wall paint until it reaches the bottom of the ash, and then spray the nano waterproofing agent twice (not very expensive). Then repaint with your favorite lacquer. In this way, at least ten or eight years, I am not afraid of black and moldy.

2. Nano waterproofing agent effect: (crystal effect) isolate the water vapor in the exterior wall and prevent the indoor water vapor from entering.

3. Because the moisture in the outdoor and indoor areas is in the wall, the water content will be black spots and moldy as soon as the water content increases. When it rains, the rain enters the wall, and in summer, the sun is scorching and the temperature is high, and the heat sucks the water vapor into the wall, but it can't be discharged, and then on a rainy day, the water from the outside enters the wall again. Over and over again, many walls will become black spots and mold.

1. Intermittent ventilation.

Mould on the top floor is usually caused by indoor dampness, so we can use intermittent ventilation. On rainy days, close the doors and windows in the south or southeast direction to reduce the amount of moisture entering the room. At noon, due to the high humidity of the air outside, it is best not to open the window, and should open the window in the afternoon or evening, when the air is drier, to adjust the air humidity.

2. Lime absorbs moisture.

The mold on the top floor can also be used in the way of lime moisture absorption, which can be placed indoors with a bag of quicklime on rainy days to make the indoor air dry.

3. Air conditioning dehumidification.

This method is relatively simple, but it consumes more electricity, and it is best to use other environmentally friendly methods to save energy.

4. Practical moisture-proof small objects.

We can also place some moisture-absorbing boxes and moisture-absorbing bags indoors, which can absorb moisture in the air, have a certain effect of dehumidification and moisture-proofing, and have a certain effect of removing mildew.

5. Shovel off the wall skin and scrape the putty.

If the moldy wall is more serious, we can shovel off the moldy wall, re-waterproof, and then scrape putty and paint.

Causes of mold on the top floor.

1. Environmental factors.

In the process of using the house, the owner does not pay attention to ventilation, and the air flow inside the room is poor, resulting in excessive indoor air humidity, and the wall is easy to absorb the floating matter containing nutrients in the air after the wall is damp, resulting in the formation of mold.

2. Waterproof problem.

The top layer is waterproof and leaking or the top layer is damaged, resulting in water leakage to the bottom layer, so that the bottom layer of the shed appears black spots and mildew.

Most of the long hair and mold are due to water leakage on the top floor, and it is best to solve the problem of water leakage on the top floor first. Then to deal with the problem of hair growth in the end, you can use the following method:

1. Remove the moldy roof and wall.

2. Brush the sealing primer to be a little thicker.

3. Re-brush the brand latex paint with great effect.

4. Because the mold on the roof and wall is caused by dampness, pay attention to more ventilation during use in the future.

There is also a method, which is treated with 84 disinfectant.

The first thing to do is to find out the cause of the mold. One is to check whether the bathroom is leaking or the kitchen is leaking, and the other is to check whether there is water leakage outside. If these two causes are ruled out, analyze whether the original walls are not dry, or whether the location of the house is caused by moisture.

If it's the latter, keep the room ventilated frequently.

In the moldy corners, there is a small shovel to scrape off the peeled walls, then putty, white, and finally wall paint, wallpaper or puddle of mud.

Method 1: Wash the wall with pure alcohol, wear protective gloves, masks and glasses during the cleaning process, and pay attention to making the wall dry thoroughly in order to avoid mold again.

Method 2: If the moldy spots on the wall are not very serious, you can use a toothbrush to brush away the mold stains, pay attention to the toothbrush to be dry, and then gently wipe it with a soft cloth dipped in alcohol, which can dry the wall and prevent mold from growing.

In this case, it may be caused by water seepage at the corner of the open-air floor slab of the ceiling, as long as the leakage is filled, the infiltration is prevented, and the moldy place is scraped off and re-brushed white.

It is that the waterproofing of the roof is not done well, and the water leakage causes mold in the corner of the top floor.

Remove the moldy parts in the corners of the wall as soon as possible, otherwise it will affect your health.

Usually, pay attention to indoor ventilation.

If the corner of the top wall is moldy, in this case, you should find out the cause. In this case, it should be damp to cause mold, and it may be that water leakage on a rainy day may also cause this reason. Only by finding the real cause can we really solve the problem.

If the corner of the top floor is moldy, you can make a compartment, because the top floor is easy to leak, so it is easy to mold.

If the corner of the top floor is moldy, you can ask a professional to make a roof waterproofing, and the effect should be much better after waterproofing.

Find out the cause of the mold first, and then reconstruct it according to the original construction method.

If the moldy spots on the wall are not very serious, you can use a toothbrush to brush away the mold stains, pay attention to the toothbrush to dry, and then gently wipe it with a soft cloth dipped in alcohol, which can dry the wall and prevent mold from growing.

1. How to deal with moldy roofs?

1.Ventilation can be carried out. When the outdoor air humidity is high, do not open the windows.

When the air is dry, ventilation can be carried out. 2.The roof can be put with lime, which can absorb moisture and make the roof drier.

3.It can be re-waterproofed, and waterproof materials can be applied to lighten the color of mildew.

2. What are the causes of moldy roofs?

1.The windows and interior cement are not tight.

Cracks in the windows and exterior cement structures made the interior windows damp and moldy roofs.

2. Decoration leads to mold on the wall.

Because decoration materials contain a certain amount of moisture, it is easy to produce mold at a certain temperature. When the wall is completely dry for renovation, moisture will be trapped in the wall, causing the roof to become moldy and mildew.

3.Exterior wall quality issues lead to mold on the roof.

If the exterior wall tiles are not laid firmly, the tile gaps are not saturated, trachoma, gaps, or when installing doors and windows, the foam filling is not dense, and gaps appear, resulting in local water seepage, which will lead to mold on the roof.

4.Waterways cause mold on the walls.

When decorating a house, sometimes the water pipes will leak during the renovation, causing the roof to be damp and moldy, especially near the bathroom, which is more likely to have mildew.

5. The waterproof performance is not good.

The roof is not waterproofed well, which leads to the destruction of the waterproof layer, water leakage and cracking, which leads to mold on the roof.

6.Environmental factors.

Lack of indoor air circulation leads to excessive indoor humidity and moldy roofs.
