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

　　1.原因可能是底座過于粗糙，打擊速度過快;

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

　　2.膩子層太厚一次施工，大于2.0mm;

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

　　3.基層含水率過高，密度過大或過小。由于膩子孔隙豐富，含水率高，不透氣，空氣在孔隙腔內封閉，不易消除。施工一段時間后，僅在表面出現氣泡爆裂，主要原因是攪拌不均勻，料漿含小于溶解的粉末顆粒，施工后，大量吸水，膨脹爆裂。

　　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.

　　如膩子粉出現大面積發泡膩子面，用鏟刀直接壓碎小泡口，再用適當的膩子刮去發泡表層;膩子粉一般攪拌均勻，靜置約10分鐘后，再用電動攪拌機在墻上攪拌均勻;施工第二層或一層表面層起泡現象，應在水印消除前用刮板壓破氣泡處理，以保證膩子表面不出現氣泡;非凡粗糙的墻面，一般基材盡量選用粗膩子粉;在墻面過干或風、光強的環境下，先盡可能用清水濕潤墻面。墻沒有清水后，進行膩子層的刮除。

　　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.

　　為了預防問題并及時解決問題，我相信我們可以避免問題。

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