It is generally necessary to apply putty for 1-3 times, so there will be 1-3 layers of putty. Many community owners look for putty, and the putty of their own walls often appears delamination today. So what is the reason? How to deal with it? Now Jinan putty powder manufacturer will answer for you.

產(chǎn)生原因：

Cause:

1、由于使用的耐水膩?zhàn)臃蹖儆诼谛停?dāng)前一道產(chǎn)品批刮在墻上時(shí)會(huì)隨著時(shí)間的延長(zhǎng)或受天氣潮濕、遇水均會(huì)增加其硬度，施工時(shí)前一道與后一道批刮施工的時(shí)間間隔較久，當(dāng)后一道施工完以后即開(kāi)始打磨，外層較松，較易打磨，當(dāng)有些地方磨穿到前一道時(shí)，由于前一道放置的時(shí)間較久，較硬，不易打磨，所以磨出來(lái)墻面兩種不同的效果，就會(huì)形成類(lèi)似分層的現(xiàn)象。

1. As the water resistant putty powder used is slower than the type, the hardness of the current product will increase with the extension of time when it is scraped on the wall or when it is wet or wet. During the construction, the time interval between the previous and the next batch is long. When the latter is completed, it will start to polish. The outer layer is loose and easy to polish. When some parts are worn through to the previous layer, the previous layer will be placed for a long time and hard, It is not easy to polish, so two different effects on the wall surface will form a similar layered phenomenon.

2、在批刮后一道時(shí)壓的太實(shí)、收的太光滑、時(shí)間間隔較久而受天氣潮濕、遇水等影響就會(huì)形成外層表膜與表層的硬度不同，當(dāng)打磨時(shí)，由于表膜與表層的硬度不同，里層較松，容易被磨深，而表膜硬度較高，不易打磨，就會(huì)形成分層現(xiàn)象。

2. After batch scraping, the hardness of the outer surface film will be different from that of the surface layer due to the influence of damp weather, water and other factors such as too solid pressure, too smooth finish and long time interval. When grinding, the inner layer is loose and easy to be worn deep due to the different hardness of the surface film and the surface layer, while the hardness of the surface film is high and not easy to be polished, which will result in delamination.

處理方法：

Handling method:

1、前一道施工完以后，因其它原因無(wú)法一次施工完整而導(dǎo)致的時(shí)間間隔較久，或因遇天氣潮濕、雨季、遇水等原因；建議其在接下來(lái)施工時(shí)應(yīng)批刮兩道膩?zhàn)臃郏@樣即可避免在打磨時(shí)會(huì)磨破底而產(chǎn)生的脫層現(xiàn)象。

1. After the completion of the previous construction, the time interval is long because the construction cannot be completed at one time due to other reasons, or due to wet weather, rainy season, water and other reasons; It is suggested that two layers of putty powder should be applied during the next construction, so as to avoid the delamination caused by the bottom being worn down during polishing.

2、批刮起后一道時(shí)應(yīng)注意不要壓的太實(shí)，需打磨的墻面不能收光，將表面的針孔、刀痕收平即可，若遇潮濕天氣（俗稱(chēng)水南天）、雨季應(yīng)暫停作業(yè)，等天氣好轉(zhuǎn)時(shí)方可作業(yè)。如已批刮完后一道時(shí)遇到潮濕天氣、下雨的應(yīng)隔天隨即打磨，避免因墻面表膜吸水回硬而產(chǎn)生的打磨脫層現(xiàn)象。

2. When scraping the next layer, care should be taken not to press it too tightly. The wall surface to be polished should not be polished, and the pinholes and knife marks on the surface should be flattened. In case of wet weather (commonly known as Shuinantian) and rainy season, the operation should be suspended, and the operation can only be started when the weather improves. In case of wet weather or rain after scraping, polish immediately the next day to avoid polishing delamination caused by water absorption and hardening of wall surface film.

注：1、壓實(shí)、拋光后的墻面不宜打磨；

Note: 1. The wall surface after compaction and polishing should not be polished;

2、雨季或潮濕天氣應(yīng)停止作業(yè)，特別是山區(qū)的地方天氣情況多變，應(yīng)特別注意。

2. Operation shall be stopped in rainy season or wet weather, especially in mountainous areas where the weather is changeable.

3、耐水膩?zhàn)臃凼┕ず笤谡５那闆r下應(yīng)在一星期以?xún)?nèi)打磨較佳。

3. Water resistant putty powder shall be polished within one week under normal conditions after construction.
