How to deal with mold on the roof quickly, how to deal with mold on the roof

Wall mold. Wall mold refers to the fungal community that uses the available carbon and nitrogen sources in the wall skin layer (usually referring to the putty layer and topcoat layer) to parasitize the surface of the wall in the form of flora and multiply in large quantities under suitable temperature and humidity, usually showing black hair, green hair, red hair, yellow hair and other forms.

Morphology and smell.

If the wall is moldy, mold will grow on the wall, and some of these wall molds will form black spots on the wall, one by one, some will grow more luxuriantly, and one large piece will even spread to the entire wall. The smell of the wall where the mold grows is more pungent, producing a "wrapping smell" similar to that produced by the mold of steamed buns, which is actually the smell of spores released by the mold on the wall filling the air. The composition of wall mold is complex, most of them are toxic, and long-term inhalation of these spores is very bad for human health.

Living conditions. Mold belongs to fungi, not bacteria, and its vegetative body is a filament with a multicellular structure, so filamentous fungi are collectively called molds. In nature, molds usually grow with hyphae and reproduce with spores.

The life activities of molds are closely related to nutrients, temperature, humidity, oxygen, pH and other factors. Mold likes acidic environment, aerobic, the most suitable growth temperature is between 25 --35, grows well under the condition of relative humidity of 90%-100%, the relative humidity drops to 80%-85%, and the growth of mold becomes slow or even stagnant. As long as there are available carbon sources, nitrogen sources and other nutrients, and the temperature is appropriate, the relative humidity is high, and the oxygen supply is sufficient, mold will grow in large numbers, and the mold will eventually cause different degrees of harm to the product.

As long as any factor related to the life activities of mold is controlled, the growth of mold will be greatly inhibited, and the product will not be corroded and destroyed by mold.

Principle of bacterial production.

1.The process of mold reproduction.

According to research reports, there are 1.5 million species of fungi on Earth, of which 65,000 have been identified. Although the types of fungi are different, the fungi that are present in buildings all have similar life cycles. The typical life cycle of a fungus is divided into four stages (as shown in Figure 2):

Spore production, germination, hyphae growth, and reproduction.

After living in a house for a long time, it is prone to various problems, such as dirty walls, or moldy roofs, etc. Generally, if the room is humid or not ventilated, the roof of the home will become moldy. So what to do if the roof is moldy?

At noon, the air humidity outside is at the highest value, and it is not appropriate to open the window, so it should be opened in the afternoon or evening, when the climate is relatively dry, open the window to adjust the indoor air.

2. Lime moisture absorption: on rainy days, quicklime can be wrapped in cloth or sacks and placed in various places in the room to keep the indoor air dry.

3. Air conditioning dehumidification: It is simpler than the first two methods, but it consumes electricity, so it is recommended to use other environmentally friendly and moisture-proof methods to save energy.

4. Shovel off the wall skin, make waterproof, and then scrape putty to brush the paint. Temporary method: Use 84 disinfectant bleach solution and apply it to the moldy area (you can brush it several times) to lighten the color of the mold.

Causes of mold on the roof.

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.

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.

Method: Repair the leakage and plug the source of the leakage; Asphalt and waterproofing materials; Mold remover sprays the wall to erase mildew; Coated with waterproof material and buckled with anti-mold board.

Most of the mold on the roof is caused by leakage. Due to the leakage caused by the aging of the house, the source should be removed first, and the leakage should be repaired.

The leakage prevention treatment of the roof part is repaired by a professional company, and depending on the situation, it can be painted with asphalt or waterproofing materials.

The exterior has been waterproofed, and the interior is coated with a layer of waterproof material, and then painted to restore the whiteness of the wall. After doing waterproofing, buckle a layer of mold-proof board in the house, so that it is not easy to mildew when leaking.

If it is caused by moisture or water leakage, the first thing to do is to waterproof the roof, and after the waterproofing treatment, the moldy roof should be thoroughly cleaned and the indoor roof should be redecorated. Long-term exposure to moldy roofs will cause damage to the human body. Causes of mold on the roof:

1. Users on the top floor are very prone to water leakage, especially for houses that are more than 10 years old, when the rainy season comes, the rain will continue to wash the roof, and will seep into the room from the aging gaps, so that the roof will enter the water. 2.
