抹面砂漿，也稱抹灰砂漿，是指涂抹在建筑物和構件表面以及基底材料表面，兼有保護基層和滿足使用要求作用的砂漿。如果說砌筑砂漿是建筑的“骨骼連接劑”，那么抹面砂漿就是建筑的“皮膚”——它不僅要保護墻體免受風雨侵蝕，還要為后續的裝飾層提供平整牢固的基層。

Plastering mortar, also known as plastering mortar, refers to the mortar applied to the surface of buildings and components, as well as the surface of base materials, with the functions of protecting the base layer and meeting the requirements of use. If masonry mortar is the "bone connector" of a building, then plastering mortar is the "skin" of the building - it not only protects the wall from wind and rain erosion, but also provides a smooth and firm base for subsequent decorative layers.

抹面砂漿的基本要求可以概括為三點：一是良好的和易性，便于形成均勻薄層；二是較高的粘結力，確保與基層牢固結合；三是一定的抗裂性能，防止砂漿層開裂。為了防止砂漿開裂，有時需加入紙筋、麻刀、有機纖維等纖維材料。為強化某些功能，還需加入陶砂、膨脹珍珠巖等特殊骨料。

The basic requirements for plastering mortar can be summarized into three points: first, good workability, which facilitates the formation of a uniform thin layer; Secondly, it has a high adhesive strength to ensure a strong bond with the base layer; Thirdly, it has a certain level of crack resistance to prevent the mortar layer from cracking. In order to prevent mortar cracking, sometimes fiber materials such as paper bars, hemp knives, and organic fibers need to be added. To enhance certain functions, special aggregates such as ceramic sand and expanded perlite need to be added.

抹面砂漿的分類按功能可分為普通抹面砂漿、裝飾砂漿、防水砂漿、絕熱砂漿等特種類型。普通抹面砂漿用于一般墻面的找平保護；裝飾砂漿在滿足保護功能的同時具有裝飾效果；防水砂漿具有抗滲功能；絕熱砂漿則用于保溫隔熱。

The classification of plastering mortar can be divided into special types such as ordinary plastering mortar, decorative mortar, waterproof mortar, and insulation mortar according to their functions. Ordinary plastering mortar is used for leveling and protection of general walls; Decorative mortar not only meets the protective function but also has a decorative effect; Waterproof mortar has anti-seepage function; Thermal insulation mortar is used for thermal insulation.

抹面砂漿的施工工藝講究分層作業。底層砂漿注重粘結性，需要保水性良好的砂漿；面層砂漿追求平整美觀，選用細砂。根據基層材料差異，磚墻底層多用石灰砂漿，混凝土基體常用混合砂漿，潮濕區域需采用具備較高強度和耐水性的水泥砂漿。分層施工的意義在于：底層解決“粘得住”的問題，面層解決“抹得平”的問題，各司其職，才能保證非常終質量。

The construction process of plastering mortar emphasizes layered operation. The bottom mortar emphasizes adhesion and requires mortar with good water retention properties; The surface mortar pursues smoothness and beauty, and fine sand is selected. According to the differences in base materials, lime mortar is commonly used for the bottom layer of brick walls, mixed mortar is commonly used for concrete substrates, and cement mortar with high strength and water resistance is required for damp areas. The significance of layered construction lies in solving the problem of "sticking" at the bottom layer and "smoothing" at the surface layer, each performing their own duties, in order to ensure the final quality.

聚合物抹面砂漿是近年來發展迅速的高性能產品。聚合物材料作為非常重要的原材料，主要起增粘、保水和抗裂作用，對抹面砂漿粘結強度的提高、性能的穩定、防裂抗裂、改善施工性等多方面起著關鍵作用。聚合物砂漿的配制通常按粉料與水4:1左右的比例，在攪拌桶內先放入適量清水，緩緩倒入干粉砂漿，用機械攪拌器攪拌均勻，靜置10分鐘后再次攪拌使用。攪拌好的聚合物砂漿應在2小時內用完，使用過程中嚴禁加水。

Polymer plastering mortar is a high-performance product that has developed rapidly in recent years. Polymer materials, as the most important raw materials, mainly play a role in increasing adhesion, water retention, and crack resistance. They play a key role in improving the bonding strength, performance stability, crack resistance, and construction performance of plastering mortar. The preparation of polymer mortar is usually carried out in a ratio of about 4:1 between powder and water. An appropriate amount of water is first added to the mixing bucket, and the dry powder mortar is slowly poured in. The mixture is then stirred evenly with a mechanical mixer and left to stand for 10 minutes before being mixed again for use. The mixed polymer mortar should be used up within 2 hours, and it is strictly prohibited to add water during use.

在外墻外保溫系統中，抹面砂漿的作用尤為關鍵。典型的施工流程為：在保溫板面抹底層抹面砂漿（厚度約2-3mm），同時將耐堿玻纖網格布繃緊后貼于砂漿表層，用抹子由中間向四周把網格布壓入砂漿中。待底層抹面砂漿凝固前再抹一道面層聚合物砂漿（厚度1-2mm），抹灰加筋層總厚度控制在3-5mm。網格布搭接寬度5-10mm，建議全部埋入、不得有皺褶。

The role of plastering mortar is particularly crucial in the external wall insulation system. The typical construction process is to apply a bottom layer of mortar (with a thickness of about 2-3mm) on the insulation board surface, while tightening the alkali resistant fiberglass mesh cloth and sticking it to the surface of the mortar. Use a trowel to press the mesh cloth into the mortar from the middle to the periphery. Before the bottom layer of plastering mortar solidifies, apply another layer of polymer mortar (thickness 1-2mm) on the surface layer. The total thickness of the plastering reinforcement layer should be controlled at 3-5mm. The overlapping width of the mesh cloth should be 5-10mm, and it must be completely buried without wrinkles.
