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.

　　这些测试的目的是为了确保质量，但如果使用不当，结果仍然是徒劳的。以下详细介绍了灰浆使用的一些基本要求:首先，大面积配筋前应设置标准。抹灰分阶段分层，每层厚度在5 - 7mm之间，水泥砂浆每层厚度为7 - 9mm，如果抹灰层总厚度超过35mm，应采取相应的加固措施。

　　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.

　　第二点，如果抹灰用的是水泥砂浆，上一层抹灰未固化前，不能进行下一层抹灰。如果用石灰砂浆抹灰，要等到前一层抹灰干了七、八成后再抹灰。第三点是抹灰底面的强度一定不能低于面层。第四点是，水泥砂浆混合后，应在初凝前用完。再没有坚硬的沙子阻挡应使用，也就是说，砂浆已经开始凝结。

　　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.

　　以上就是使用济南抹面砂浆单层的具体需要注意的一些事情，我们希望严格按照施工的要求，对于不同原材料的灰浆，有不同的操作标准，这也是需要特别注意的。

　　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.
