They are all good, and can release negative oxygen ions. Are very environmentally friendly. Negative oxygen sludge has a base and a surface, the base replaces putty, and the surface replaces latex paint and diatom mud. Depends on what effect you want. If the water-based negative oxygen sludge is used as the basic negative oxygen sludge, it will have the same effect as scraping putty and painting. Of course, you can also use the latex paint on it. If you use water-based negative oxygen sludge, you can actually scrape putty below. There is no need to spend more money, if it is the artistic space of negative oxygen mud. Scraping putty at the bottom is also possible. You can make various textures and patterns on it. If you are worried about wall cracking, you can use negative ion wallpaper. Dimison negative oxygen mud has a negative ion wallpaper called Turandot, which can also release negative oxygen ions. Personally, I prefer Dimison's negative oxygen mud art space series. If you have texture, you can customize the pattern according to your own style. If you like plane, you can blow putty at the bottom and use water-based negative oxygen mud on it, which is useful and functional. Mainly depends on your needs, there is no good, only suitable.
