The top floor is very humid on a rainy day

Moisture on the top floor can be caused by:

1.Roof leakage: Poor roof or tile damage can cause rainwater to seep into the house, causing dampness and mildew.

2.Impermeable: The interior of the house lacks conditions such as ventilation and ventilation, which is prone to the formation of dampness.

3.Leaking water pipes in the house: If the water pipes inside the house are leaking, the water flow may collect near the top floor, causing dampness.

4.Water vapor accumulation: Actions such as bathing and cooking produce water vapor, which can lead to dampness if it is not adequately discharged.

5.Groundwater: If there is groundwater around the house, it can cause the roof of the house to also be infiltrated by water vapor, causing the top floor to become wet.

6.The reason that there are no waterproofing measures or improper insulation of the wall in winter, and there is a gap between the indoor temperature and the condensation on the surface of the wall.

To completely solve the problem of dampness on the top floor, it is necessary to take corresponding measures for the above causes, such as repairing roof leaks, enhancing house ventilation, checking and repairing water pipe leaks, and strengthening indoor insulation.

Waterproofing is not in place.

The house on the top floor will be damp, in general, the reason is that the waterproofing of the roof is not in place, affected by rainwater, the rainwater will seep into the top floor, and then seep into the wall, and the inside will produce moisture, the best way is to do a good job of waterproofing after checking the leakage point outside the roof, and the years have come up, especially for more than 15 years in the house, the cement on the roof will almost have a certain amount of water seepage.

The house on the top floor will be damp, and the reason is usually because the waterproofing of the roof is not in place. Under the influence of rainwater, it will seep into the top layer and then into the walls, creating moisture inside. The best way to do this is to do a good job of waterproofing the roof after checking the outside for leaks.

The age is up, especially if the house is more than 15 years old, and the cement on the roof will almost have a certain amount of water seepage.

The top floor of the building will leak, which is actually a common problem on the top floor. Because waterproofing measures cannot be perfect. After the house is blown by the wind and the sun. It's going to crack too, whatever.

There are many reasons why the top floor is damp, mainly including the following:

1.The upstairs has been flooded for a long time, causing the roof to be damp.

2.The waterproofing layer on the roof of the building was damaged, resulting in water leakage.

3.Cement has a certain degree of water absorption, and being soaked for a long time will cause water to penetrate downward through the cement little by little, resulting in dampness on the roof.

4.During the rainy season or on southerly days, the air humidity is high, and the moisture in the air condenses and disturbs the water droplets on the walls and floors, resulting in a very humid room.

5.If the house is not waterproofed during decoration, or the water pipe joint is leaking, or the water pipe is broken by an electric drill, etc., the water pipe will leak.

6.If the upstairs waterproofing is not done well, or the upstairs water pipe leaks, or the exterior wall is not waterproofed, etc., the water leakage will cause the interior to be very damp. Zhao Li Ran.

The damp original Huaicha code on the top floor may be due to the leakage or seepage of the lead roof or ceiling, resulting in the damp indoor air at the top of the roof. It can also be caused by poor top structure, untimely maintenance, or poor ventilation. In addition, in a humid environment, the growth of mold and bacteria will also increase, which can lead to problems such as itching, allergies, etc.

In order to solve this problem, we can take corresponding measures, such as strengthening house maintenance, dealing with water leakage problems in a timely manner, regular ventilation and installation of ventilation equipment to keep indoor air fresh and suitable.

<>1. Water has accumulated upstairs for a long time. If it is the top floor, the upstairs has accumulated water for a long time, and the ordinary waterproof cannot withstand long-term soaking, which will cause the roof to be damp, and even drip downwards in serious cases. 2. The waterproof layer is damaged.

If there is a crack in the waterproof layer, as long as there is water, it will leak like the lower layer, and if the waterproof of the bathroom is damaged, the downstairs bathroom will drip water. 3. Water absorption of cement. Any cement has a certain degree of water absorption, and if it is soaked for a long time, the moisture will penetrate down little by little through the cement, causing the roof to be damp.

Summary. The reason for the high air humidity in the home on the top floor is pro! Hello, I am happy to answer for you<> the reason for the high air humidity at home is that when the rainy season or the south wind day, the air humidity is high, and the moisture in the air condenses into water droplets on the wall, ground, etc., resulting in a very humid interior.

If the house is not renovated well, the water pipe joint will leak, or the water pipe will be drilled by an electric drill, etc., which will cause the water pipe to leak. Water pipes are usually buried in the wall floor, and the pipes have water seepage, which will make the wall and floor very wet over time. If the waterproofing of the upstairs is not done well, or if there is a leak in the upstairs water pipe, or if the exterior wall is not waterproofed properly, etc., it will cause the interior to be very damp and so on.

How can we solve the underlying problem.

The air humidity in the home now reaches 75% in the season

It is the reason that there are no waterproof measures or improper insulation of the wall in winter, and there is a gap with the indoor temperature and condensation forms on its surface. To completely eliminate the occurrence of condensation, it is recommended to strengthen the internal insulation is more effective. You can use dynamic thermal insulation wall panels to install on the wall to prevent the wall from being cold and cause the wall to be damp and mildew, and the wall will not be moldy, but these phenomena are normal on the top floor, and it is best to ventilate more during the day and take waterproof measures.

Isn't it a hassle to solve this problem?

That's right

The room has long been in this condition, the roof is full of mildew, because it is a flat roof my house is on the top floor, I thought it might be a leak in the roof, looking for a property to make up for it.

Remove the moldy wall, first brush a layer of 108 glue, and then scrape putty and latex paint.

The walls in the house are often damp and moldy: because the moisture from both the outside and the interior is in the walls, the water content will become black spots and mold. 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.

Treatment: 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.

Nano waterproofing agent effect: (crystal effect) isolate the moisture in the exterior wall from entering, and do not let the indoor moisture enter.
