墙面抹面沙浆强度低、标号不够、脱沙掉粉、空鼓开裂、凹凸不平……出现以上情况,不少人都会感觉摊上大事了！简直就像是豆腐渣工程。不过，若只是表面这些现象也可能没你想像的那么严重，只要主体结构没毛病，这些表像的问题是相对容易解决的。

The strength of the wall plastering mortar is low, the label is not enough, the sand and powder have fallen off, the hollowing and cracking, and the unevenness... Many people will feel like a big deal has been laid out! It's like a Tofu-dreg project. However, if only on the surface, these phenomena may not be as serious as you imagine. As long as the main structure is not faulty, these surface problems are relatively easy to solve.

墙面脱沙掉粉，当然是抹面沙浆强度低，标号不够引起的。而墙面沙浆层空鼓、开裂，又恰恰可能是抹面沙浆中水泥用量过大或强度过高造成，特别是开裂。（这里要注意的是：分清是墙面沙浆开裂还是主体墙开裂？主体墙开裂不在此列）。

The peeling of sand and powder on the wall is of course caused by the low strength of the plastering mortar and insufficient labeling. And the hollowing and cracking of the wall mortar layer may be caused by excessive cement content or strength in the plastering mortar, especially cracking. (It should be noted that distinguishing between wall mortar cracking and main wall cracking is not included here.).

那么济南抹面沙浆强度低如何解决呢？

So how to solve the low strength of Jinan plastering mortar?

如上述，墙面抹面沙浆强度低就会导致墙面脱沙掉粉。要解决这一问题很简单，使用沙干净就可以了，抹面沙浆强度低就用沙干净。

As mentioned above, low strength of wall plastering mortar can cause the wall to lose sand and powder. To solve this problem, it is simple to use sand to clean it, and if the strength of the plaster mortar is low, use sand to clean it.

引起沙浆层空鼓开裂，排除主体墙结构问题外，多数是因为沙浆强度过高，即水泥沙子配比时水泥用量过大，各位有心的朋友可以留意一下，墙体沙浆强度越高的，裂纹裂缝越多、越明显。

The reason for the hollowing and cracking of the mortar layer, excluding the structural problems of the main wall, is mostly due to the high strength of the mortar, that is, the excessive amount of cement used in the cement sand ratio. Interested friends can pay attention to this. The higher the strength of the mortar on the wall, the more and more obvious the cracks and cracks.

沙浆层空鼓，一般是指墙体基层与抹面沙浆层之间粘结不牢，或是抹面沙浆密实度不足导致的脱层现象。

The hollowing of the mortar layer generally refers to the phenomenon of loose bonding between the wall base and the plastering mortar layer, or delamination caused by insufficient compactness of the plastering mortar.

修复方法：

Repair method:

(1)清扫墙体表面的浮沙浮灰，将沙干净墙面脱沙修复液搅拌均匀，然后喷涂于墙面，使墙面充分湿润，以不流走为宜，中度或重度脱沙的抹灰墙间隔30分钟后喷涂第二遍（吸料渗透过快的间隔10-20分钟，具体以现场测试为准）。8小时后检查，若局部未达到效果的，分析原因或进行第三次喷涂补料。

(1) Clean the floating sand and floating ash on the surface of the wall, mix the sand clean and sand removal repair solution evenly, and then spray it on the wall to make it fully wet, preferably without flowing away. For plastered walls with moderate or severe sand removal, spray the second coat after an interval of 30 minutes (the interval for rapid material absorption and penetration is 10-20 minutes, subject to on-site testing). After 8 hours of inspection, if the effect is not achieved locally, analyze the cause or conduct a third spray repair.

(2)对于年久已风化、抹面沙浆中水泥失效（或水泥含量过分太低的）或沙子泥土含量过大引起的抹灰层脱沙问题，这类情况会影响“沙干净”效果，此类墙面需将旧抹灰层铲除，重新抹灰。

(2) For plastering layers that have weathered for a long time, have cement failure in the plastering mortar (or have too low cement content), or have excessive sand and soil content, which can affect the "sand cleaning" effect, such walls need to be removed from the old plastering layer and re plastered.

水泥墙面标号不足，抹灰墙面硬度差，增加墙面硬度，墙面脱沙掉灰，墙壁掉沙起砂，毛坯房掉沙翻砂，提高水泥墙面标号，内外抹灰墙面掉灰，改变水泥沙浆强度，水泥沙浆强度不达标，墙面松软掉沙，增加强度密度，水泥砂浆标号不足低、解决墙面脱沙掉粉，墙面起砂翻沙，清水墙面掉沙起砂，搓砂墙面掉灰脱沙，旧墙翻新，墙面空鼓脱皮。

Insufficient cement wall markings, poor plastering wall hardness, increased wall hardness, wall detachment and dust removal, wall detachment and dust removal, rough room detachment and sand turning, increased cement wall markings, internal and external plastering wall detachment, changed cement mortar strength, cement mortar strength not meeting standards, wall looseness and sand falling, increased strength density, insufficient cement mortar markings, solution to wall detachment and dust removal, wall detachment and sand turning, clear water wall detachment and sand turning, Dust and sand fall off the sanded wall, old walls are renovated, and the walls are hollowed and peeled off.
