1. Humid environment: If the room is poorly ventilated and humid, mold and bacteria can easily breed on the wall, leading to mildew and long hair.
2. Water leakage: If the room leaks, water will seep into the wall to form accumulated water, thus promoting the growth of mold and bacteria.
3. Paint quality problem: low-quality paint is easy to crack or peel off, which exposes the substances inside the wall and leads to the growth of mold and bacteria.
4. Indoor environmental pollution: pollutants in indoor air (such as formaldehyde, etc.). ) will volatilize into the air, further affecting the chemical composition of wall materials, accelerating its aging and damage, and also leading to the appearance of long hair.
5. Improper cleaning: If the room is often not cleaned or cleaned with an inappropriate cleaner, dust and dirt will remain on the wall, providing conditions for the growth of mold and bacteria.
