抹面砂浆与其他的砂浆相比，具有以下特点： ①抹面层不承受荷载。 ②抹面层与基底层要有足够的粘结强度，使其在施工中或长期自重和环境作用下不脱落、不开裂。 ③抹面层多为薄层，并分层涂抹，面层要求平整、光洁、细致、美观。 ④多用于干燥环境，大面积暴露在空气中。 抹面砂浆应用与基面牢固地粘合，因此要求砂浆应有良好的和易性及较高的粘结力。抹面砂浆常分两层或三层进行施工。底层砂浆的作用是使砂浆与基层能牢固地粘结，应有良好的保水性。中层主要是为了找平，有时可省去不做。面层主要为了获得平整、光洁地表面效果。 Compared with other mortar, the plaster mortar has the following characteristics: (1) the plaster layer does not bear the load. 2. There should be enough bond strength between the coating layer and the base layer, so that it will not fall off or crack during construction or long-term self weight and environment. (3) the coating layer is mostly thin layer, and is applied layer by layer. The surface layer requires smooth, clean, meticulous and beautiful appearance. 4. It is mainly used in dry environment and exposed to air in large areas. The application of the plaster mortar is firmly bonded to the base surface, so the mortar should have good workability and high cohesive force. The plaster mortar is often divided into two or three layers for construction. The role of bottom mortar is to make mortar and base firmly bonded, and should have good water retention. The middle level is mainly for leveling, sometimes it can be omitted. The surface layer is mainly used to obtain smooth and smooth surface effect.
