凡涂抹在建筑物或建筑構件表面的砂漿，統稱為抹面砂漿。

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

　　根據抹面砂漿功能的不同，可將抹面砂漿分為普通抹面砂漿、裝飾砂漿和具有某些特殊功能的抹面砂漿（如防水砂漿、絕熱砂漿、吸音砂漿和耐酸砂漿等）。

　　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).

　　對抹面砂漿要求具有良好的和易性，容易抹成均勻平整的薄層，便于施工。還應有較高的黏結力，砂漿層應能與底面黏結牢固，長期不致開裂或脫落。

　　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.

　　抹面砂漿底層主要起的作用是粘結

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

　　底層砂漿的作用是使砂漿與基層能牢固地粘結，具有良好的保水性，以確保砂漿層與底面能夠緊密黏結，長期不致開裂或脫落。

　　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.

　　這一層的主要功能是提供粘結力，確保上層砂漿和中層砂漿能夠穩定地附著在基面上，從而形成一個平整、均勻的表面層。

　　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.
