1. Environmental protection

Wall paint occupies 70% of the indoor area and is also one of the main sources of pollution from indoor decoration materials. Whether it is environmentally friendly is also the issue that most people are most concerned about. International professional environmental monitoring organizations certify these brands. By comparing the "certificates" of these wall paints, we can make a preliminary judgment.

a White paint is more environmentally friendly than heavy-colored paint

Colored paint, especially heavy-colored paint, requires the addition of more color pastes and adhesives, and contains mercury, Formaldehyde, benzene and other harmful substances can easily exceed standards. Therefore, we see that Fenlin paint on the market does not have heavy colors and this is also the reason. Dufang paint has poor coverage and is difficult to apply evenly because it has less adhesive.

b Water-based latex paint is generally more environmentally friendly than wallpaper.

The reason is that the country has strict quality control standards for interior wall latex paint. Compared with latex paint products, the wallpaper industry is relatively chaotic, and national standards are not uniform enough. Except for a few well-known imported and domestic brands, the quality of most small and medium-sized brand products in the market varies. At present, cheap wallpapers in the domestic market are still mainly made of PVC, so they inevitably contain harmful substances such as formaldehyde. In addition, the quality of the base treatment and adhesive for pasting wallpaper is also a major hidden danger of wallpaper contamination.

In addition, full-paper wallpaper can continuously absorb and release VOC, and has a protective effect on indoor VOC. Therefore, PVC and non-woven fabrics are more suitable for interior decoration.

c The volatilization cycle of harmful substances in wall paint

The harmful substances in wall paint are mainly VOC, followed by formaldehyde, heavy metals, etc. VOC is highly volatile. It is most toxic when painting. VOCs ranging from 70 to 90 will evaporate. In other words, the painters will be the most seriously affected. It is recommended that you do not go in during painting. At that time, harmful gases are most volatile. sharp. Harmful substances can be released 70% after three days. Once the coating is applied to form a film and is completely dry, the release of harmful substances is minimized.

So don’t rush to move in after redecoration, when there is sufficient drying and ventilation period. You can choose Dufang or Dulux high-end. Dulux's high-end models that have passed international environmental protection certification are much more expensive than ordinary models. After all, the Chinese standards and some international environmental certification standards are very different.
