The quality of putty layer is very important. The wall cracking, peeling, hollowing, peeling and other problems are basically caused by the foundation layer, rarely the quality of latex paint, so a good foundation layer is very critical. What kind of putty powder wall needs to be removed?

1、用手摸上去，手上會(huì)留白，或者噴點(diǎn)水，流下來(lái)的是白水，這樣的情況說(shuō)明膩?zhàn)淤|(zhì)量差，建議鏟掉。

1. If you touch it with your hand, it will leave white on your hand, or spray some water, and white water will flow down. This shows that the putty is poor in quality. It is recommended to shovel it off.

2、墻面有空鼓、脫落、開(kāi)裂等情況，這些已經(jīng)暴露出問(wèn)題了，當(dāng)然建議鏟掉重新做，否則直接刷漆就是自找麻煩。如果是局部問(wèn)題，可以局部鏟掉重做。

2. The wall is hollowing, falling off, cracking, etc., which has exposed problems. Of course, it is recommended to shovel it off and redo it. Otherwise, painting directly is asking for trouble. If it is a local problem, it can be removed and redone.

有人會(huì)問(wèn)，我的是新房子，并非二手房也需要鏟掉重新做嗎?這個(gè)其實(shí)只關(guān)乎墻面質(zhì)量，跟新房二手房沒(méi)關(guān)系。現(xiàn)在開(kāi)放商毛坯房交付基本上都做好了膩?zhàn)樱琴|(zhì)量卻不一定好，就跟開(kāi)放商的水電材料和開(kāi)關(guān)一樣，很多是用的比較一般的材料。因?yàn)殚_(kāi)放商只要達(dá)到60分就可以交付了，這樣成本比較低，而我們自己住卻需要90分的質(zhì)量。

Some people will ask, what I have is a new house, but not a second-hand house. Do I need to shovel it and rebuild it? In fact, this is only about the quality of the wall, and has nothing to do with the new house and second-hand house. At present, the rough houses delivered by the developers are basically puttied, but the quality is not necessarily good. Like the hydropower materials and switches of the developers, many of them are made of ordinary materials. As long as the developers reach 60 points, they can deliver. This is a low cost, but we need 90 points for our own living.

有的裝修公司不管新房二手房，全部建議都鏟掉重做，這也是另一個(gè)結(jié)果，還是看墻面質(zhì)量而定，如果本身質(zhì)量挺好的話，省點(diǎn)錢也好的，特別是有些二手房的墻面質(zhì)量很不錯(cuò)。

Some decoration companies, regardless of the new houses and second-hand houses, suggest that they all remove and redo them. This is another result. It depends on the quality of the wall. If the quality is good, it is also good to save money, especially the wall quality of some second-hand houses is very good.

有的裝修隊(duì)認(rèn)為不鏟影響也不大，因?yàn)殓P墻較吃力，而且有的工錢并不高、費(fèi)工時(shí)。因?yàn)閴γ鎲?wèn)題通常出現(xiàn)在裝修完工一年后，那時(shí)候裝修隊(duì)的影子都找不到了，關(guān)他什么事呢。

Some decoration teams think that the impact of not shoveling is not great, because it is hard to shovel the wall, and some of them do not pay high wages and take much time. Because the wall problem usually occurs one year after the completion of the decoration. At that time, the shadow of the decoration team can not be found. What matters to him.
