Diatom mud, wallpaper, wall covering and art paint are better. Because diatom mud is the most popular environmental protection material, it is highly recommended by many people. As long as you see it on the Internet, it has its function, absorbing noise, protecting the environment, in addition to formaldehyde, purifying fresh air, sterilizing and preventing fire. Diatom mud is made of diatomite, which is famous for its rough feel and many pores. People fished it out of the sea and put some diatom mud made of glue on it, so its characteristics were not destroyed and it absorbed formaldehyde. It is a very environmentally friendly material and has a good water absorption effect. This level is suitable for southern decoration. Diatom mud can also be made into various colors, but the construction is very difficult. We should pay attention to environmental protection in decoration, because safety is our greatest concern. 2, wallpaper wall cloth, its pattern is the best of the three, its aesthetic degree is also the best, its price is also various, such as non-woven fabrics, canvas are very good, can be made into all kinds of wallpaper, but its disadvantage is that it is particularly fond of mildew, and there are harmful ingredients in it, which is less environmentally friendly and very easy to mildew, so people are reluctant to use it again. Its quality is also much worse, so it is not safe to use. 3, art paint, although not particularly beautiful, but not like moldy wallpaper, it is more natural than wallpaper, and will not bubble, but it also has its own shortcomings, its practice is difficult to do, if you are not a professional, you can't do it in art paint, and it will be ugly if you don't do it well. Its durability is also very long. If it is not deliberately removed, it will not fall off, so these three are better than diatom mud, no matter from the aspects of environmental protection or aesthetics. But no matter what materials are used for decoration, we must ensure our safety and use environmentally friendly materials for decoration, so as to ensure our health.
