[0002] In the construction of building decoration projects, before the decorative surface of the wall is constructed, the wall needs to be leveled. Generally, cement mortar is used to cover and level the masonry and concrete structure of the building for the first time. After the cement mortar is dried and hardened, putty powder is needed to level the wall for the second time. When the putty layer is dried and hardened, the operator needs to use sandpaper to grind it. This process is time-consuming and labor-intensive, and requires high experience and technical skills of the operator. The construction quality is difficult to guarantee, so a grinder is needed.
