At present, the commonly used wall materials are wallpaper, emulsion paint and putty powder. Other wall materials such as soft bag and diatom mud will not be analyzed for the time being. Wallpaper is generally divided into non-woven, pure paper, PVC, cloth, etc. As long as these wallpapers are regular brands, they are environmentally friendly, but what about the taste? Yes.

無紡和純紙材質的壁紙，都有木頭的味道，毫無疑問他們是環保的。PVC材質無論是進口的還是國產的多少帶點塑料的味道，但是一定不能刺鼻。所以說壁紙是有味道的，但是這正好證明了壁紙材質的天然環保。

Both non-woven and pure paper wallpapers have the smell of wood. There is no doubt that they are environmentally friendly. PVC material, whether imported or domestic, has a little plastic taste, but it must not be pungent. So the wallpaper has a taste, but it just proves that the wallpaper material is natural and environmentally friendly.

乳膠漆也是有味道的，即便是打出吸甲醛噱頭的產品也一樣會有味道，正規廠家的乳膠漆即便是有味道，當然它也是環保的，只要不是刺激性的氣味，都是環保的。

Latex paint also has a taste. Even products with formaldehyde absorption gimmicks will have a taste. Even if the latex paint of regular manufacturers has a taste, of course, it is also environmentally friendly. As long as it is not a pungent smell, it is environmentally friendly.

膩子粉墻面就是俗稱的刮大白，目前主流刮大白用的膩子粉同樣是有味道的，但是只做刮大白的墻面不僅環保而且更能吸附甲醛，這就是刮大白的神奇之處。

Putty powder wall is commonly known as scraping white. At present, the mainstream putty powder for scraping white also has a taste, but the wall only scraping white is not only environmentally friendly, but also can absorb formaldehyde. This is the magic of scraping white.

而一點味道沒有的墻面材料則是加入了化學成分，掩蓋了氣味，未必就是好的環保的。

The wall materials without any taste are added with chemical components to cover up the smell, which may not be good environmental protection.

墻面材料是不是越貴越好？

Is the wall material as expensive as possible?

選擇墻面材料要選擇適合自己的，預算范圍內的材料就可以了，不要想著如果購買貴的產品就可以保持多少年都流行，裝修跟服裝一樣，每時每刻都在淘汰，新的風格、產品層出不窮，所以我們只要“裝在當下”即可。另外只要是正規的產品，基本上都是環保的，價格便宜也好，價格貴也好，只選適合自己的就可以。

When choosing wall materials, we should choose materials suitable for ourselves and within the budget. Don't think that if we buy expensive products, we can keep popular for many years. Decoration, like clothing, is being eliminated all the time, and new styles and products are emerging one after another, so we just need to "install at the moment". In addition, as long as they are regular brand products, they are basically environmentally friendly, cheap or expensive. Just choose what suits you.
