Dot with screed means: when building decoration, the plastering area of the wall is large. Before plastering, mortar is used to make small ash cakes (also called dots) at a certain distance on the wall, and then mortar is used to make one or several ash bars along the vertical and horizontal direction of the small ash cakes (generally the distance is not greater than 1.5m) to control the thickness and smoothness of plastering.

Before plastering, determine the wall plastering thickness, and prepare block mortar to ensure smoothness and verticality, which is used to control the construction quality, generally 50mm square. The main purpose of making ash cake is to ensure the thickness of mortar and control its consistency. ?

The main purpose of making ash cake is to ensure the thickness of mortar and control its consistency. "Corner protection" refers to the external corner of the internal wall of a building (such as the corner of doors, windows, stairwells and other walls). First, a vertical mortar with a width of about 3 cm is applied to the wall, and the height is from the ground to the ceiling, that is, "standard reinforcement". The minimum thickness of plastering mortar is 0.5 cm, and the maximum thickness is determined by the inclination of the wall. Because it is a strip, the verticality of the strip surface can be well controlled. When plastering the wall, that is, between the "standard poles", the verticality and flatness of the plastering surface are controlled by using the verticality and flatness of two standard poles.
