1、 Differences between plastering mortar and crack resistant mortar

1、抹面砂漿

1. Plastering mortar

用于涂抹建筑物或建筑物表面的砂漿，都叫抹面砂漿。根據抹面砂漿的功能不同，可分為普通抹面砂漿、裝飾砂漿、防水砂漿、隔音砂漿等。對抹面砂漿的要求時需要具有良好的和易性，容易涂抹成均勻的薄層，便于基面施工。同時還需要提高粘結力，砂漿層應與基層粘結牢固，長期不開裂或者不脫落。在潮濕的環境中或者易受外力作用的區域(如地面和墻裙)，還需要有較高的耐水性和強度。

The mortar used to coat buildings or their surfaces is called plastering mortar. According to the different functions of plastering mortar, it can be divided into ordinary plastering mortar, decorative mortar, waterproof mortar, soundproofing mortar, etc. The requirement for plastering mortar is to have good workability, easy to apply into a uniform thin layer, and facilitate the construction of the base surface. At the same time, it is also necessary to improve the bonding strength, and the mortar layer should be firmly bonded to the base layer, without cracking or falling off for a long time. In humid environments or areas susceptible to external forces, such as floors and wall skirts, high water resistance and strength are also required.

抹面砂漿一般是薄抹灰，而且抹面砂漿還有破板率的要求。成本比抗裂砂漿高，保溫板的變形比較大，柔性相對好一些。

The plastering mortar is generally thin plastering, and there is also a requirement for the breakage rate of the plastering mortar. The cost is higher than that of crack resistant mortar, the deformation of insulation board is relatively large, and the flexibility is relatively better.

2、抗裂砂漿

2. Crack resistant mortar

抗裂砂漿一般是指聚合物抗裂抹面砂漿，是聚合物改性的水泥基抹面抗裂砂漿，用于砂漿墻面、保溫系統的表面增強保護。它具有高強度，良好的粘結力、極強的抗裂效果。抗裂砂漿的優劣影響著保溫系統的使用效果和壽命，采用抗裂砂漿進行抹面的保溫系統能有效解決外墻保溫、隔熱、防風壓、耐候、透氣等問題。易于操作、施工簡單，能長期保持使用性能，環保安全。

Anti crack mortar generally refers to polymer anti crack plaster mortar, which is a polymer modified cement-based plaster anti crack mortar used for surface reinforcement protection of mortar walls and insulation systems. It has high strength, good adhesion, and extremely strong crack resistance. The quality of crack resistant mortar affects the effectiveness and lifespan of the insulation system. The insulation system using crack resistant mortar for plastering can effectively solve problems such as external wall insulation, heat insulation, wind pressure resistance, weather resistance, and breathability. Easy to operate, simple to construct, able to maintain long-term performance, environmentally friendly and safe.

抗裂砂漿做得厚一些，成本低一些。

The crack resistant mortar is made thicker and has a lower cost.

二、抗裂砂漿的注意事項

2、 Precautions for cracking resistant mortar

1、抗裂砂漿施工的時候不需要添加其他材料，同時需要嚴格控制水料比例。

1. During the construction of crack resistant mortar, no other materials need to be added, and the water material ratio needs to be strictly controlled.

2、基層吸水性強或者表面干燥過快的話，應該先在基層潤濕后，涂刷一層界面劑做封底處理。

2. If the base layer has strong water absorption or the surface dries too quickly, it should be moistened first before applying a layer of interface agent for sealing treatment.

3、運輸過程中應注意防潮防水。

3. During transportation, attention should be paid to moisture and waterproofing.

4、抗裂砂漿在儲存的過程中應保持通風、避免受潮。

4. During the storage process of crack resistant mortar, ventilation should be maintained to avoid moisture.

5、施工時，一次性不要調配過多，需要視施工用量而定，如出現未使用而干固的結塊，則不能繼續使用。

5. During construction, do not mix too much at once, it depends on the construction amount. If there are dry and solid lumps that have not been used, they cannot be used again.

6、施工的環境應保持在5攝氏度以上，雨雪天氣不能施工。

6. The construction environment should be maintained above 5 degrees Celsius, and construction cannot be carried out in rainy or snowy weather.
