How to deal with the moldy wall on the first floor, and the damp wall on the first floor is often mo

What should I do if my walls are moldy?

Wipe off the mold and open the windows for ventilation.

In cases where mold is not too severe, it is enough to scrub the walls with 80% alcohol. Pay attention to ventilation when washing, and wear protective gloves, masks and glasses. In order to avoid re-emergence of mold, care should be taken to dry the walls thoroughly, eliminate the causes of mold, and properly heat and ventilate.

During wet weather, try to keep windows open as little as possible. In addition, try to make the wall dry, and in wet weather, you can use a dehumidifier, air conditioner, and fan to absorb the moisture on the wall. As soon as moisture appears on the wall or home, it should be wiped off immediately with a dry rag.

There is no good way to solve it completely, and my family has encountered it. I shoveled off the heavy powder layer of the exterior and interior walls, used waterproof paint on the outside, and latex paint on the inside, and mildew appeared again in less than a year.

If the wall is damp, it is normal for the local climate to be humid or the back of the damp wall is damp, and the wall is damp due to water seepage from the back.

1. Thoroughly clean the peeled and damp wall with a shovel.

2. Continue to remove the floating ash on the wall to prevent the floating ash from affecting the bonding strength.

3. Evenly brush the separator with a brush and apply it 2-3 times, with an interval of about 3 hours between each time.

4. After the isolator is dried, the putty can be scraped in batches, and the batch scraping time is not less than 24 hours each time.

5. After the putty is dried, carefully polish it with No. 180 sandpaper.

6. Clean the surface dust and paint latex paint 2-3 times, with an interval of about 6 hours between each time.

Mold on the walls of the home is a very common problem, mainly caused by dampness, poor ventilation, lack of sunlight, etc. Mold on the walls not only gives people an uncomfortable feeling, but also harms health, as mold can cause allergies, respiratory infections, and other problems, so it needs to be dealt with promptly.

1. Clean the wall.

The first thing you need to do is to clean the wall thoroughly, either with bleach or a professional cleaner. If it is only mild, you can spray it with baking soda or white vinegar mixed with water, brush it evenly with a brush or cloth, and then rinse it off with clean water. If the mold is severe, it needs to be cleaned with bleach or a specialist cleaner.

2. Enhance ventilation.

Increasing ventilation is essential to prevent mold on the walls. Ventilation can be enhanced by drilling holes in the wall or installing exhaust fans. During the rainy season or the season with high humidity, special attention should be paid to ventilation to prevent mildew on the walls.

3. Control humidity.

Controlling humidity is key to preventing mold on walls. You can use a dehumidifier to adjust the humidity in the room and open the windows regularly for ventilation. Also, don't put too many plants or objects on the wall, as this will affect the ventilation and dryness of the wall.

Fourth, waterproof treatment.

Waterproofing is also one of the effective ways to prevent mold on the wall. You can paint waterproof paint on the wall or paste professional waterproof materials such as rubber prototype board on the wall. This ensures that the wall is dry, prevents moisture from penetrating in, and avoids mold on the wall.

In short, to deal with mold on the wall at home, we need to start from the four aspects of cleaning, ventilation, humidity control and waterproofing, and solve the problem in a targeted manner in order to effectively prevent mold on the wall.

There can be many reasons for mold on the walls on the first floor, mainly including the following aspects:

1.High humidity: When the humidity in the room is too high, the moisture in the air will condense and retain on the wall, creating a warm, humid environment that is perfect for mold growth.

2.Poor ventilation: The room is poorly ventilated, the air cannot be circulated, and the pollutants in the air cannot be discharged, which is also one of the reasons for the mold on the wall. Loose wheel masking.

3.Exposure to moisture: For example, in damp basements or walls that are exposed to the outside for a long time, they are susceptible to moisture and mold growth.

4.Water leakage or water seepage: Leaking pipes, water seepage from roofs, etc. can also cause dampness on the walls, which can induce mold growth.

5.The wall material is not breathable: If the wall material is not breathable, or it is enclosed by thermal insulation materials, it will cause moisture to be unable to be released, resulting in dampness on the wall and the growth of mold.

In view of the above reasons, we can prevent or solve the mold on the wall in the following ways:

1.Strengthen ventilation: open windows frequently for ventilation to maintain indoor air circulation.

2.Pay attention to the humidity in the house: use a dehumidifier, install an exhaust fan, etc. to control the humidity in the house.

3.Deal with water leakage in time: If there is water leakage or water seepage in the room, you should find a professional to deal with it in time to avoid water retention on the wall.

4.Choose the best wall materials: choose high-quality wall materials with good air permeability, which is conducive to wall ventilation and reduces moisture.

5.Pay attention to wall cleaning: Wash the wall regularly to keep it dry and clean to prevent mold growth.

1. The indoor and outdoor temperature is large, and the wall insulation is not done well, resulting in a large temperature difference between indoor and outdoor.

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 and shouting that the acres of wax roads are resistant.

3. There is also the cause of rainwater infiltrating indoors.

1. First of all, you need to check whether there is water leakage at home; 2. Remove mildew in time; 3. After the mildew on the wall is removed, the wall should be leveled with elastic putty powder; 4. Then brush the latex paint of the same color as the wall.

The details are as follows:

1. For the mold on the wall, first of all, we must detect whether there is a leakage place, such as the toilet or kitchen and balcony, we must find the cause of the mold, find the location of the leakage point, and only completely solve it can be done once and for all.

2. When there are small mildew spots on the wall, you can also spray it with bleaching powder, spray it on the moldy wall, wait until it is dry, wipe it gently with a soft rag, and when the mold is not particularly serious, you can use the alcohol content of about 75% to clean the wall, which can quickly decompose the mold on the wall.

3. Reduce the number of windows opened in rainy weather, so that the room is in a dry state, and you can also control the humidity at home with the help of a dryer or dehumidifier when the rainy season comes.

4. For the case of more mold on the wall, it is necessary to be served by a professional teacher, after sanding the wall with sandpaper, then using a professional knife to shovel it, leveling the wall with elastic putty, and painting it with the same color as the wall after the putty is dry.
