Our first impression of the basement is that there are things in the storage room that we don't usually need. But the basement of the villa is different, because it transforms the storage room with single function into a huge living space in daily life. Chongqing decoration industry experts suggest that with the continuous upgrading of decoration technology, many villa owners like to decorate the villa basement into a home theater, gym, children's room, private reception room, bar and so on. It's really unique and brings you different feelings. Waterproof and moistureproof are the construction elements, and the key problem of basement decoration is waterproof and moistureproof treatment. Waterproofing is aimed at the "ceiling", while moistureproofing is aimed at walls and floors. There are many good moisture-proof and waterproof coatings on the market at present. In addition, it is also an effective method to add moisture-proof layer on the wall and ground. Speaking of moisture-proof, vitrified brick is an ideal basement floor material; For walls, waterproof paint or wallpaper is much better than sticking bricks. In addition, in the process of construction, the owner also needs to slow down and pay special attention to some small details. For example, wall painting must wait until the wall latex paint is completely dry before doing other processes, because if it is not dry, it is easy to have insufficient flatness or "small honeycomb" phenomenon. In the process of basement decoration, the environmental protection of materials is also very important. The ventilation performance of the basement itself is not ideal, so it is necessary to minimize the decoration links with high formaldehyde content such as carpentry. Glass can be used in the basement with insufficient light to increase the refraction of light and supplement the lack of indoor light. Ventilation and lighting are also important. A successful basement must be safe, and "scenery" is the design focus, that is, ventilation and lighting. Daylighting can be met by design, and ventilation depends entirely on the nature of the basement. If it is a semi-basement, the situation is relatively better, and you can borrow more "half windows" in the decoration. If it is a whole basement, it is difficult to make up for the air circulation problem. For the whole basement, it is precisely because of the problem of air circulation that the designer does not recommend transforming it into a permanent space. In the light treatment, the combination of internal lighting and external natural light is an ideal basement lighting mechanism. In other words, there must be a constant light or a group of lights in the basement. If you want to have a more sense of design, you can let constant light pass through the ground glass to produce soft and slow light, creating a hazy and romantic atmosphere for the basement. In terms of air circulation, especially in the whole basement, there must be ventilation equipment, and then some vibrant green plants can be added according to the situation, which can greatly improve the air quality in the basement.
