很多人以為抹面砂漿就是水泥加沙子隨便拌一拌。這個認知大錯特錯。抹面砂漿有明確的分類和用途，用錯了輕則墻面不平，重則空鼓脫落。

Many people think that plastering mortar is just a mix of cement and sand. This cognition is completely wrong. There are clear classifications and uses for plastering mortar. If used incorrectly, it can result in uneven walls or hollowing and peeling.

抹面砂漿是什么？ 抹面砂漿是涂抹在建筑物或建筑構件表面，兼有保護基層并滿足使用要求的砂漿統稱。它不同于砌筑砂漿——砌筑砂漿負責“粘磚”，抹面砂漿負責“抹平墻面”。

What is plastering mortar? Smearing mortar is a general term for mortar applied to the surface of buildings or building components, which not only protects the base layer but also meets the requirements for use. It is different from masonry mortar - masonry mortar is responsible for "sticking bricks", while plastering mortar is responsible for "smoothing walls".

抹面砂漿按功能分3大類：

The plastering mortar is divided into three categories according to its function:

第一類：普通抹面砂漿。 用于磚石墻表面的常規抹灰。常見配比：石灰：砂=1:2～1:4。適用于干燥環境的墻面抹灰。不潮濕的房間墻面和天花板，可用石灰：石膏：砂=1:0.6:2～1:1:3。

Type 1: Ordinary plastering mortar. Conventional plastering for the surface of brick and stone walls. Common ratio: Lime: Sand=1:2~1:4. Suitable for wall plastering in dry environments. A non humid room wall and ceiling can be made of lime: gypsum: sand=1:0.6:2 to 1:1:3.

第二類：防水抹面砂漿。 用于浴室、潮濕車間等墻裙、勒腳或地面基層。配比：水泥：砂=1:3～1:2.5。勒腳、女兒墻外腳等防潮部位，用石灰：水泥：砂=1:0.5:4.5～1:1:5。潮濕環境建議用防水砂漿，普通砂漿上去就受潮脫落。

Type 2: Waterproof plastering mortar. Used for wall skirts, footholds, or ground substrates in bathrooms, damp workshops, etc. Mixing ratio: cement: sand=1:3-1:2.5. Use lime: cement: sand=1:0.5:4.5~1:1:5 for moisture-proof parts such as footholds and parapet walls. Waterproof mortar must be used in humid environments, as ordinary mortar will peel off when exposed to moisture.

第三類：聚合物抹面抗裂砂漿。 主要用于外墻外保溫系統中保溫層外的抗裂保護層。配比中包含水泥、砂、石灰，還添加可再分散乳膠粉、纖維素醚等聚合物成分。目的是抗裂、增強粘結力，防止保溫層開裂。

Category 3: Polymer coated anti cracking mortar. Mainly used as a crack resistant protective layer outside the insulation layer in external wall insulation systems. The ratio includes cement, sand, lime, and polymer components such as redispersible latex powder and cellulose ether. The purpose is to resist cracking, enhance bonding strength, and prevent cracking of the insulation layer.

不同基層用不同砂漿：磚墻底層多用石灰砂漿；混凝土基體常用混合砂漿；潮濕區域需用高強度耐水水泥砂漿。

Different mortar is used for different base layers: lime mortar is often used for the bottom layer of brick walls; Common mixed mortar for concrete matrix; High strength water-resistant cement mortar is required in damp areas.

一句話總結：普通墻面用普通抹面砂漿，衛生間浴室用防水砂漿，外墻保溫用抗裂砂漿。用錯了地方，再好的施工也白搭。

Summary in one sentence: Ordinary wall surfaces use ordinary plastering mortar, bathrooms use waterproof mortar, and exterior wall insulation uses crack resistant mortar. Using the wrong place, even the best construction is useless.
