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，手就會留下白色”或“噴水，流動的是白色的水”，這樣的情況下膩子質量較差，建議鏟掉。

　　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、墻面空鼓、脫落、開裂等情況下，這些都暴露出了問題，當然建議鏟掉再做一次，或者直接刷油漆就是自找麻煩。如果是局部問題，可以部分刪除并重新執行。

　　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.

　　有人會問，我是新房，不是二手房還需要鏟掉再做一次嗎?這其實只是關于墻面質量，與新房二手房無關。現在輸送的原材料基本上都是用膩子做的，但質量不一定好，用開水電的材料和開關，很多都是用一般的材料。因為開發人員只需要實現60個交付點，所以成本相對較低，而我們需要90個質量點來獨自生活。

　　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.

　　有的裝修公司不管新房二手房，所有的建議都是挖走重做，這是另一個極端，還是看墻的質量，如果質量好，省下一些錢就是好的，尤其是有的二手房的墻質量非常好。

　　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.

　　有的裝修隊伍為什么說“不鏟效果也不太好”，因為鏟墻比較費力，而且有的工資不高，在耗費勞動力的時候。由于墻面問題在完成一年后似乎正常裝修，那么裝修團隊的影子就找不到，關自己什么事。

　　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.
