Because wall mold is a highly viable flora, mold reproduces by diverging spores, and when killed in one location, it will also grow elsewhere. If the environment in which it grows is not completely eliminated or its flora is killed, it will multiply and spread rapidly in the corresponding environment.

The reasons for this problem: 1. Structural reasons. Most of the buildings are frame structures, the walls are full of walls, the wall surface is easily cracked by the combination of beams and columns, it is the weak link of insulation and waterproofing, water seepage in summer, and cold in winter.

2. Construction reasons. The exterior wall bricks are not inlaid, the brick joints are not full or joints are used, the outer wall is not satisfied, trachoma, the gap forms a cold and hot bridge, the wall and beam column joints are not densely filled, resulting in cracks, and when the doors and windows are installed, the foam filling is not dense and there are gaps. 3. Environmental reasons.

In summer, it is rainy in the south and the air humidity is high, the coastal areas are humid, and in the northern regions, the climate is cold in winter, the walls are cool, and the indoor temperature is very high and it is easy to condense. The insulation of the outer wall itself is not good, which causes the walls to be cold, and the indoor water vapor will crystallize into water droplets on the walls, and the walls will become moldy when they are wet. 4. Reasons for life.

In the process of using the house, do not pay attention to ventilation, indoor air circulation is not good, resulting in excessive humidity in the room, and the damp wall is easy to adhere to the nutrients in the floating substance. At the same time, the indoor air, the floating material contained in the production mold will adhere to the wall and be prone to mildew.
