凡涂抹在建筑物或建筑构件表面的砂浆，统称为抹面砂浆。

　　Any mortar applied to the surface of buildings or building components is collectively referred to as plastering mortar.

　　根据抹面砂浆功能的不同，可将抹面砂浆分为普通抹面砂浆、装饰砂浆和具有某些特殊功能的抹面砂浆（如防水砂浆、绝热砂浆、吸音砂浆和耐酸砂浆等）。

　　According to the different functions of plastering mortar, it can be divided into ordinary plastering mortar, decorative mortar, and plastering mortar with certain special functions (such as waterproof mortar, insulation mortar, sound-absorbing mortar, and acid resistant mortar).

　　对抹面砂浆要求具有良好的和易性，容易抹成均匀平整的薄层，便于施工。还应有较高的黏结力，砂浆层应能与底面黏结牢固，长期不致开裂或脱落。

　　Good workability is required for the plastering mortar, which is easy to apply into a uniform and flat thin layer for easy construction. There should also be a high bonding force, and the mortar layer should be able to bond firmly with the bottom surface, without cracking or falling off for a long time.

　　抹面砂浆底层主要起的作用是粘结

　　The main function of the bottom layer of plastering mortar is to bond

　　Plastering mortar is a type of mortar applied to the surface of buildings or building components. According to their different functions, it can be divided into ordinary plastering mortar, decorative mortar, and plastering mortar with certain special functions.

　　底层砂浆的作用是使砂浆与基层能牢固地粘结，具有良好的保水性，以确保砂浆层与底面能够紧密黏结，长期不致开裂或脱落。

　　The function of the bottom layer mortar is to firmly bond the mortar with the base layer, with good water retention, to ensure that the mortar layer can tightly bond with the bottom surface and not crack or fall off in the long term.

　　这一层的主要功能是提供粘结力，确保上层砂浆和中层砂浆能够稳定地附着在基面上，从而形成一个平整、均匀的表面层。

　　The main function of this layer is to provide adhesion, ensuring that the upper and middle layers of mortar can stably adhere to the base surface, thereby forming a flat and uniform surface layer.
