Putty powder sometimes appears bubbles after construction or a period of time. reason:

　　1.原因可能是底座过于粗糙，打击速度过快;

　　1. The reason may be that the base is too rough and the strike speed is too fast;

　　2.腻子层太厚一次施工，大于2.0mm;

　　2. The putty layer is too thick for one construction, more than 2.0mm;

　　3.基层含水率过高，密度过大或过小。由于腻子孔隙丰富，含水率高，不透气，空气在孔隙腔内封闭，不易消除。施工一段时间后，仅在表面出现气泡爆裂，主要原因是搅拌不均匀，料浆含小于溶解的粉末颗粒，施工后，大量吸水，膨胀爆裂。

　　3. The moisture content of the base course is too high, the density is too large or too small. Due to the rich pores, high moisture content, airtight, air in the pore cavity closed, not easy to eliminate. After construction for a period of time, only bubbles burst on the surface, the main reason is that the mixing is uneven, the slurry contains less than the dissolved powder particles, after construction, a large number of water absorption, expansion burst.

　　如腻子粉出现大面积发泡腻子面，用铲刀直接压碎小泡口，再用适当的腻子刮去发泡表层;腻子粉一般搅拌均匀，静置约10分钟后，再用电动搅拌机在墙上搅拌均匀;施工第二层或一层表面层起泡现象，应在水印消除前用刮板压破气泡处理，以保证腻子表面不出现气泡;非凡粗糙的墙面，一般基材尽量选用粗腻子粉;在墙面过干或风、光强的环境下，先尽可能用清水湿润墙面。墙没有清水后，进行腻子层的刮除。

　　If the putty powder has a large area of foaming putty surface, use a blade to directly crush the small bubble mouth, and then use a suitable putty to scrape off the foaming surface; generally, the putty powder is evenly stirred, and after standing for about 10 minutes, use an electric mixer to evenly stir on the wall; In order to avoid bubbles on the surface of the second or last layer of the construction, a scraper shall be used to break the bubbles before the watermark is eliminated to ensure that there is no bubbles on the putty surface; for the particularly rough wall, the coarse putty powder shall be used as far as possible as the general base material; in the environment where the wall is too dry or the wind and light are strong, the wall shall be wetted with clear water as possible first. When there is no clear water on the wall, the putty layer shall be removed.

　　为了预防问题并及时解决问题，我相信我们可以避免问题。

　　In order to prevent problems and solve them in time, I believe we can avoid problems.
