抹面砂漿主要施工于各種墻體保溫面層，形成優(yōu)異抗裂防滲面層，有利于保護(hù)保溫基層的綜合性能，提高保溫面層界面的親和性，為后序飾面材料施工提供優(yōu)異的界面基層。下面來講講濟(jì)南抹面砂漿常遇這三種質(zhì)量問題怎么解決。

Plastering mortar is mainly applied to various wall insulation surface courses to form an excellent crack resistant and anti-seepage surface course, which is conducive to protecting the comprehensive performance of the insulation base course, improving the affinity of the insulation surface course interface, and providing an excellent interface base course for the subsequent finishing material construction. Now let's talk about how to solve the three quality problems often encountered in Jinan plastering mortar.

（1）空鼓

(1) Empty drum

主要原因是：①基層處理不干凈，如基層表面附著的灰塵和疏松物、脫模劑和油漬等，這些雜物不清除干凈會影響抹灰層與基層的粘結(jié)。

The main reasons are: ① The base course is not cleaned, such as the dust and loose matter, release agent and oil stains attached to the base course surface, which will affect the bonding between the plastering layer and the base course if not cleaned.

②有凹處或一次抹灰太厚等，在砂漿干燥之前砂漿層由于重力作用已與基層脫離。

② The mortar layer has been separated from the base course due to gravity before the mortar is dried due to concave or too thick plastering at one time.

③界面處理不當(dāng)或未做界面處理，基面過于光滑，不能抑制砂漿的干縮導(dǎo)致砂漿層與基層脫離。

③ Improper interface treatment or no interface treatment is made, and the base surface is too smooth to prevent mortar from drying and causing separation of the mortar layer from the base course.

抹灰前應(yīng)將基層清掃干凈，并提前2-3天開始向墻面澆水，滲水深度達(dá)10毫米后方可施工，有深凹處，應(yīng)提前補(bǔ)平砂漿。另外，應(yīng)提前噴涂好界面砂漿。

Before plastering, the base course shall be cleaned, and the wall shall be watered 2-3 days in advance. The construction can be started only after the water penetration depth reaches 10mm. If there are deep recesses, the mortar shall be filled in advance. In addition, the interface mortar shall be sprayed in advance.

（2）脫層

(2) Delamination

主要是由于底層灰層過干。防治方法除按規(guī)范要求施工外，如發(fā)現(xiàn)底層已干，應(yīng)清水濕潤、待底層濕潤透后再抹面層。

It is mainly because the bottom ash layer is too dry. In addition to the construction according to the specification requirements, if the bottom layer is found to be dry, it shall be wetted with clean water, and the surface layer shall be plastered after the bottom layer is thoroughly wetted.

（3）爆灰

(3) Explosive ash

主要原因是材料質(zhì)量不好，有雜質(zhì)或泥土。施工前應(yīng)仔細(xì)檢查材料質(zhì)量，砂子要經(jīng)細(xì)篩篩分后方能使用。

The main reason is the poor quality of materials, impurities or soil. Before construction, the material quality shall be carefully checked, and the sand shall be screened before use.

（4）裂縫

(4) Cracks

主要原因是抹灰層過厚而未采取抗裂措施或由于空鼓而產(chǎn)生的開裂，如果抹灰面很厚，施工中應(yīng)先填底層，或在底灰抹好后噴防裂劑進(jìn)行處理。

The main reason is that the plastering layer is too thick and no crack resistance measures are taken or cracks are caused by hollowing. If the plastering surface is very thick, the bottom layer shall be filled first during construction, or the anti crack agent shall be sprayed after the bottom plaster is plastered.

水泥抹灰砂漿出現(xiàn)以上情況，應(yīng)該進(jìn)行返工修復(fù)，修復(fù)時，將脫層、空鼓、爆灰及裂縫部分清除干凈，再按規(guī)范要求進(jìn)行局部的抹灰。

In case of the above situations, the cement plastering mortar shall be reworked and repaired. During the repair, the delamination, hollowing, mortar explosion and cracks shall be removed, and then the local plastering shall be carried out according to the specification requirements.

此外要注意抹面砂漿現(xiàn)場施工不需添加任何外加劑，嚴(yán)格控制水固比和抹灰時間。運(yùn)輸過程中應(yīng)注意防潮、防雨、防曝曬。抹面砂漿在儲存過程中，應(yīng)存放在干燥通風(fēng)處，避免受潮。關(guān)注我們http://m.man5g.cn，了解更多內(nèi)容！

In addition, it shall be noted that no admixture is required for on-site construction of plastering mortar, and the water solid ratio and plastering time shall be strictly controlled. During transportation, pay attention to moisture-proof, rainproof and sun proof. The plastering mortar shall be stored in a dry and ventilated place to avoid moisture during storage.
