What are the hazards of mold on the walls of the room?

The main area of mold is the wall between the bathroom and the living room, which can be seen with obvious watermarks. : It should be the reason why the bathroom decoration is not waterproof, which causes infiltration.

When decorating the house, you should do a good job of waterproofing on the floor and surrounding walls of the bathroom. The humidity in the bathroom is heavy, especially on the wall near the shower area, which is often eroded by water vapor and will cause the wall to become moldy or even fall off. If the walls of your home have been seriously eroded, then you have to redo the waterproofing of the walls!

When my house was being renovated, the decoration master told us the importance of waterproofing the house, so I went to study the waterproofing of the house, and specially chose the waterproof coating of Dunlop brand, which can be waterproof and mildewproof at the same time. Once the walls of your home get damp and moldy, it will...

We have lived in the house for a long time and there will be a lot of problems, and moldy walls are a very common wall problem, especially in the south. When it rains, the walls are prone to mold. Mold on the walls not only affects the mood of the occupants, but also harms our bodies.

So I'll talk about itThe walls of the room are moldyWhat's there.

The walls of the room are moldyAfter mold, the walls will emit moldy spores. Moldy spores are very harmful to our human body. Once they are in the air, they will multiply rapidly after inhaling the respiratory system.

If you come into contact with and inhale mold for a long time, it is easy to cause respiratory diseases, allergies, etc., and people with low immunity may cause headaches, fever, mucous membrane inflammation, etc. after inhalation.

1. The wall is moldy because it returns to the south, and the moisture in the air is heavier, and when it encounters the surface of a cold object, it gathers and produces water droplets. It is prone to mold when water vapor adheres to and wets the surface of the wall paint film for a long time, which usually occurs in ceilings, vignetting, etc.

2. The mold of the wall may also be due to the poor quality of the paint used on the wall, and the poor antibacterial and anti-mildew properties of the paint. Water vapor can easily penetrate into the walls, causing mold to grow.

1. Mild mold. If the walls are only mildly mildewed, use a rag to remove mold remover, bleach solvent, disinfectant, etc., or spray it with a small spray can. Mold should be cleaned first. After 24 hours, wipe with a clean cloth and a small amount of water.

2. If the wall is more serious, you can first take out the mold surface with sandpaper or a blade, and then spray the wall with a release agent or bleaching solution, and repair the wall with putty, after the putty layer is completely dry, apply a closed primer or an anti-mildew alkali-resistant primer, and finally apply an anti-mildew topcoat.

The above is about:The walls of the room are moldyI hope it will be helpful to you if you have any questions.

What's going on with moldy walls in housesCurrently, many guests' ceilings, bedrooms, dining rooms, and other spaces are made of keels and planks, with a surface covered with a layer of paint. Under normal conditions, the moisture content of the board is relatively low, but when the humidity in the air is very high, the board is more likely to absorb water than the wall surface, and when the ventilation is poor or the temperature is low, mold is more likely to form.

For example, in kitchens, bathrooms and other areas of the walls, there is excessive humidity in daily life, but it usually does not become moldy due to waterproofing. However, when he returned to Nantian, there was a "moisture covering effect" that caused the already moist area to become wetter, leading to a mold condition.

Due to temperature asymmetry and poor ventilation, some dark corners of the walls are more susceptible to mold. In some areas where light is often seen and is well ventilated, there is very little mold.

The coating is slightly mildew-resistant, and those who studied politics in high school know that internal factors are the deciding factor. In the case of the mold on the wall, it is mainly caused by the insufficient antibacterial and antibacterial properties of the paint product itself. Due to the low mold resistance of the product, water vapor easily penetrates into the inner layers of the wall, which makes the mold easy to grow.

If it is a wall paint with a clean smell with a good mold effect, the surface of the wall is difficult to mold even if the humidity is high.

Improper application of wall paint, improper treatment during the wall coating process can also easily lead to mold in the paint film. Let's take a look at the incorrect construction methods that can make the walls moldy.

The paint is diluted too much, and the paint must be mixed before the walls are painted. At this time, if the dilution is excessive, it is easy to make the coating film too thin, which weakens the anti-mildew function of the paint film, which makes it easier for water vapor to penetrate.

When the humidity is too high, please pay attention to the weather conditions when painting the wall. If the humidity is too high, the paint film will dry too slowly. If no other measures are taken, the paint film will be easy to form.

Hope aboutWhat's going on with moldy walls in housesThe introduction is useful to you.

Frequent mildew indicates that the wall still has the phenomenon of moisture return when decorating, and it should be ventilated more often, and it can be a moisture insulation facility for the wall.

Because the walls are the easiest place to absorb water, the way they will often get moldy is to dry them often or dry them with something hot.

1. The temperature difference between indoor and outdoor is large. The wall insulation is not done well, resulting in a large temperature difference between indoor and outdoor, and the water vapor in the indoor air is pre-condensed to the wall, which will cause the wall to be damp for more than a long time. If you are not sure if it is caused by the quality of wall insulation, there is a very simple inspection method, you can try it at home:

Knock on the wall with an inspection hammer and listen to the sound, if the sound is dull, it means that the wall is not well insulated; Conversely, if the sound is hollow, it means that the wall is insulated. Of course, poor selection of insulation materials will also cause the wall to be damp, then it depends on whether there are cracks in the wall, if there are cracks, you can consider replacing the insulation materials.

2. If the water supply pipes and drainage pipes leak, the owners in the northern region should also pay attention to checking the heating pipes of their homes. Leakage in pipes can also lead to dampness and mold in the walls over time. You can ask a professional to do a suppression test to detect.

The water pipe pressure test is one of the common methods to judge whether the water pipe connection is reliable, if the pressure test fails, it can indicate that there is a leak at a certain point of the pressure pipe.

Method.

1. Brush off with a toothbrush, if the wall has mildew, the area is not large. We can use a toothbrush to brush off the mold with a toothbrush, and then wipe it with a soft cloth moistened with alcohol. This allows the walls to dry and prevents further mold growth.

Method. Second, change the new wallpaper, if the moldy area is too large, you can change the wallpaper again. If the home itself is pasted with wallpaper, then the wallpaper must be replaced. The lifespan of the wallpaper itself is not long, and it must be completely replaced after being wet.

Because of the different production batches of wallpaper, only part of it cannot be changed like latex paint, and it is easy to have color differences. So at least the entire wall should be replaced.

Method. 3. Re-paint repair, back to the south is a weather resurgence phenomenon, when the water vapor adheres to and infiltrates the surface of the wall paint film for a long time, it is easy to induce mold on the surface of the paint film. The solution is to repaint the latex paint to solve the mold on the wall. If you want the walls to stop mold, you must first solve the dampness problem in the home before the walls can effectively mold again.

My community property and house cat to find a house cooperation, if you have any questions to the property consultation, I don't know if there is so the community has cooperation, you can go to the property to ask.

2. We can mix the bleaching and water commonly used at home, according to the ratio of 1:99, and then spray the mixed cleaning agent on the wall, wipe it with a rag first, and finally wash it again with water. Or other fungicides can also be washed, and finally put on a top coat, which should be moisture-proof.

3. There is also a more direct method, which is to shovel the original wall section clean, and then re-paint it. Remember to make sure it is completely dry before proceeding to the next step of construction.

2. If the window is not closed in time on a rainy day, the moisture will infiltrate into the room, resulting in a damp scene on the wall, or the airtightness of the window will not be good, which will also allow the external rainwater to seep into the room, resulting in the condition of mold on the wall.

3. The constant temperature process of the house wall is not perfected, which will cause the temperature difference between indoor and outdoor to be too large to a certain extent, so that the water in the indoor air will condense on the wall after encountering cold air, resulting in moisture on the wall. How to deal with mold on the wall of the room: the harm of mold on the wall to the human body.

When the wall is moldy, it will make the volatile germs continue to flow with the air, and after the human body touches and inhales for a long time, it will cause respiratory diseases and some allergic symptoms, and for some children or the elderly, it may also cause headaches, fever and other diseases.

1. Pay attention to the temperature and humidity of the latex paint wall.

For some of the owners of the landing and the completion of the urgency, we must pay attention to the temperature and humidity during the construction, if the repair range is within 10, the natural drying of the wall sail takes 5-10 days, generally speaking, the most suitable temperature for the construction is about 20 °, if the indoor temperature does not reach 5 °, it will make the latex paint not easy to form a film.

2. It is best to replace the damaged wallpaper as a whole.

If the wall is plastered with wallpaper, once it is disturbed by moisture, it should be replaced with a new wallpaper immediately, so as not to damage the wall inside.
