Friends who have decoration experience at home may encounter the situation that there is a layer of floor special gypsum powder on the floor after decoration. It is also very troublesome to clean up the white layer. What's the use of these floor plaster? How to clean it up?

其實，除了粉刷墻面的粉刷石膏粉，地板專用石膏粉是裝修時非常常用的石膏粉種類，只是它們都藏在地板下方，我們不能直接見到。

In fact, in addition to plastering wall plaster powder, floor special plaster powder is a very common type of plaster powder when decoration, but they are hidden under the floor, we can't see directly.

地板專用石膏粉常見的用處是用來找平。所謂的找平，就是在鋪設(shè)地板前需要保證基礎(chǔ)底面的平整，防止地板鋪設(shè)好后，由于底面的不平整造成空響。這是對地板的一種保護(hù)，也能夠一定程度上延長地板使用壽命。

The common use of floor gypsum powder is for leveling. The so-called leveling is to ensure the smoothness of the foundation bottom before laying the floor, so as to prevent the floor from causing empty sound due to the unevenness of the bottom.
