The quality of putty layer is very important, wall cracking, peeling, hollow drum, falling off and other problems occur, mainly because of the underlying reasons, rarely the quality of latex paint, so a good underlying is the key. What kind of walls need to be shoveled down?

　　1、“用手摸上去，手就会留下白色”或“喷水，流动的是白色的水”，这样的情况下腻子质量较差，建议铲掉。

　　1. "If you touch it with your hand, the hand will leave white" or "water spray, the water flowing is white". In this case, the putty quality is poor, so it is recommended to erase it.

　　2、墙面空鼓、脱落、开裂等情况下，这些都暴露出了问题，当然建议铲掉再做一次，或者直接刷油漆就是自找麻烦。如果是局部问题，可以部分删除并重新执行。

　　2. Under the circumstances of empty wall, falling off and cracking, all these problems have been exposed. Of course, it is suggested to shovel and do it again, or to brush paint directly is to ask for trouble. If it is a local problem, it can be partially deleted and re-executed.

　　有人会问，我是新房，不是二手房还需要铲掉再做一次吗?这其实只是关于墙面质量，与新房二手房无关。现在输送的原材料基本上都是用腻子做的，但质量不一定好，用开水电的材料和开关，很多都是用一般的材料。因为开发人员只需要实现60个交付点，所以成本相对较低，而我们需要90个质量点来独自生活。

　　Someone will ask, I am a new house, not a second-hand house need to be shoveled out and done again? This is only about the wall quality, and has nothing to do with the second-hand house of the new house. At present, the raw materials are basically made of putty, but the quality is not necessarily good. Most of the materials and switches used for power and electricity are made of general materials. Because developers only need to achieve 60 delivery points, the cost is relatively low, and we need 90 quality points to live alone.

　　有的装修公司不管新房二手房，所有的建议都是挖走重做，这是另一个极端，还是看墙的质量，如果质量好，省下一些钱就是好的，尤其是有的二手房的墙质量非常好。

　　Some decoration companies, whether new or second-hand housing, all the suggestions are to dig out and redo, which is another extreme, or look at the quality of the wall, if the quality is good, save some money is good, especially some second-hand housing wall quality is very good.

　　有的装修队伍为什么说“不铲效果也不太好”，因为铲墙比较费力，而且有的工资不高，在耗费劳动力的时候。由于墙面问题在完成一年后似乎正常装修，那么装修团队的影子就找不到，关自己什么事。

　　Why do some decoration teams say that "no shovel effect is not very good", because shovel walls are more laborious, and some wages are not high, when labor is consumed. Because the wall problem seems to be normal decoration after one year, so the shadow of the decoration team can not be found, what matters to them.
