How to prevent moisture and water in the renovation of old houses?

In the renovation of old houses, moistureproof and waterproof is a crucial link, especially in the rainy season and humid areas in the south. Here are some ways to help prevent moisture and water:

1. Make waterproof layer

Before decoration, first check whether there are cracks or loopholes in the wall and ground of the house. If there are these problems, they should be fixed first. Then, the walls and floors are coated with a layer of waterproof materials such as waterproof paint, waterproof glue and waterproof agent to ensure the moisture-proof and waterproof effect.

2. Install doors and windows

Doors and windows are places where indoor air circulates. If doors and windows are not installed, the air circulation will be affected. The tightness of doors and windows is also very important. Make sure there is no gap between the wall and the frame. Gaps near doors and windows can be filled with sealant or waterproof plastic coating.

Choose the right material

In the renovation of old houses, we should pay attention to the selection of decoration materials with good characteristics such as moisture-proof, waterproof, mildew-proof and insect-proof, such as gypsum board, waterproof floor, waterproof wallpaper and waterproof paint. If you want to change the original platform, you can lift the platform, prepare the cement and fill it evenly.

Keep the room dry.

If you want to prevent the house from getting wet, you should keep it dry indoors. Using a humidifier can increase the relative humidity, but it also needs to be disassembled and cleaned regularly. In addition, measures such as using dehumidifier and opening tuyere can be taken to keep the room dry.

5. Do a good job in roof maintenance

The roof is the most vulnerable part of the house to rain erosion. In the renovation of old houses, roof maintenance should be done well. Check the roof for cracks or leaks, and if so, repair it in time. Covering the roof with a layer of waterproof material can be better moisture-proof and waterproof.

In a word, moisture-proof and waterproof is a very important work in the renovation of old houses. Only by taking effective measures can we ensure the quality and service life of the house.
