  The base absorbs the moisture in the plaster plaster slurry, which will also cause the plaster plaster to crack, so in the construction process, according to the difference in the base material, the construction environment and the temperature, it is necessary to spray water properly and evenly to ensure that the base meets the humidity required by the construction, and then plaster。Plastering should ensure that there is no clear water on the surface of the wall base。
