A product must be tested before leaving the factory, plastering mortar is no exception. When the finished product leaves the factory, the corresponding test report will be indicated at the time of receiving. Through these, customers can know its quality. There are four main test items of Jinan plastering mortar: consistency, water retention rate, strength and adhesion. The above items shall be tested with the same manufacturer, type, grade and mortar batch.

　　這些測試的目的是為了確保質量，但如果使用不當，結果仍然是徒勞的。以下詳細介紹了灰漿使用的一些基本要求:首先，大面積配筋前應設置標準。抹灰分階段分層，每層厚度在5 - 7mm之間，水泥砂漿每層厚度為7 - 9mm，如果抹灰層總厚度超過35mm，應采取相應的加固措施。

　　The purpose of these tests is to ensure quality, but if used improperly, the results are still in vain. The following describes some basic requirements of mortar use in detail: first, standards should be set before large-area reinforcement. The plastering is divided into stages and layers, each layer is between 5-7mm thick, and each layer of cement mortar is 7-9mm thick. If the total thickness of the plastering layer exceeds 35mm, corresponding reinforcement measures shall be taken.

　　第二點，如果抹灰用的是水泥砂漿，上一層抹灰未固化前，不能進行下一層抹灰。如果用石灰砂漿抹灰，要等到前一層抹灰干了七、八成后再抹灰。第三點是抹灰底面的強度一定不能低于面層。第四點是，水泥砂漿混合后，應在初凝前用完。再沒有堅硬的沙子阻擋應使用，也就是說，砂漿已經(jīng)開始凝結。

　　Second, if cement mortar is used for plastering, the next plastering cannot be carried out before the previous plastering is solidified. If lime mortar is used for plastering, it shall not be plastered until 70% or 80% of the previous plastering is dry. The third point is that the strength of the plastering bottom must not be lower than the surface layer. The fourth point is that after the cement mortar is mixed, it should be used up before the initial setting. No more hard sand should be used, that is, the mortar has begun to set.

　　以上就是使用濟南抹面砂漿單層的具體需要注意的一些事情，我們希望嚴格按照施工的要求，對于不同原材料的灰漿，有不同的操作標準，這也是需要特別注意的。

　　The above are some things that need to be paid attention to when using the single layer of Jinan plastering mortar. We hope that there are different operation standards for different raw materials of mortar in strict accordance with the construction requirements, which also needs special attention.
