Putty, as a kind of wall decoration material, can make the wall clean and fresh, but if the details are not handled properly, it will appear putty layer bubbling and other phenomena, resulting in uneven decoration and painting, affecting the beauty, bursting bubbles will spread harmful substances to the body and other hazards. And what is the cause? Jinan putty powder manufacturer tells you why putty foams:

　　1. 攪拌不平均。

　　1. Uneven stirring.

　　2. 膩子加水過多，拌得太濕。

　　2. Putty with too much water, mixing too wet.

　　3.基層含水率過高，同時密度太大或太小。由于含有豐厚的空隙。膩子含水率高，因此不透氣，容易使施工過程中，膩子粉層的下部含有空氣，不易排出，所以就容易起泡。

　　3. The moisture content of base course is too high and the density is too high or too small. Because of the rich voids. Putty has high moisture content, so it is impermeable and easy to make the lower part of the putty powder layer contain air, which is not easy to discharge, so it is easy to foam.

　　4.基面存在細小孔洞，刮涂時膩子粉將孔洞內空氣擠壓，擠壓后的空氣反彈變成氣泡。

　　4. There are small holes in the base surface. Putty powder extrudes the air in the holes when scraping, and the air rebounds into bubbles after extrusion.

　　5.密封性較好的基面透氣性較差。

　　5. The base surface with better sealing has poor air permeability.

　　6.單層批刮過厚，膩子層的空氣沒有完整擠壓出來。

　　6. Single-layer batch scraping is too thick, putty layer of air is not completely squeezed out.

　　7.基層過于粗糙，有細小孔洞。批刮時膩子將孔洞內空氣緊縮，之后空氣壓力反彈構成氣泡。

　　7. The grass-roots is too rough with small holes. During batch scraping, the putty compresses the air in the hole, and then the air pressure rebounds to form bubbles.

　　8.基底過于粗糙，沒有打磨平整，膩子施工過程中批墻速渡過快，招致膩子粉不平均惹起的。

　　8. Base is too rough, not polished flat, putty construction process batch wall speed too fast, resulting in putty powder uneven caused.

　　9..耐水涂料、高標號混凝土等密閉性好的基面不透起泡。

　　9. Waterproof coatings, high-grade concrete and other well-sealed base surfaces are impervious to foaming.

　　10.高溫施工時膩子易產生氣泡。

　　10. Putty is easy to produce bubbles during high temperature construction.

　　11.基材吸水量過低。招致膩子批刮時相對保水時間過長而使膩子在墻上長期處于漿料態而不干，使氣泡易產生。

　　11. The water absorption of the base material is too low. When the putty is scratched in batches, the relative water holding time is too long, and the putty is in the slurry state for a long time on the wall, which makes the bubbles easy to produce.

　　12.墻面太濕潤的緣故。

　　12. The wall is too wet.

　　13..不容易被泥刀擠壓出！而產生針孔狀毛孔，就是為什么工程上批刮模板頂比墻體氣泡更多的緣由，墻體吸水量大，而模板頂吸水量極低。

　　13. Not easy to be squeezed out by a clay knife! The formation of pinhole-like pore is the reason why there are more bubbles on the top of scraping formwork than on the wall. The water absorption of the wall is large, while the water absorption of the top of formwork is very low.

　　14..纖維素添加量過大。

　　14. Excessive cellulose addition.

　　15.施工一段時間后，才在外表呈現的爆裂起泡，主要是攪拌不平均形成的，漿體中含有來不及溶解的粉狀顆粒，施工后，大量吸收水分，溶脹構成爆裂。

　　15. After a period of construction, the explosion and foaming appeared on the surface mainly due to uneven mixing. The slurry contains powdery particles that can not be dissolved. After construction, a large amount of water is absorbed and swelling constitutes explosion.

　　處理辦法：

　　Approaches:

　　1.呈現大面積起泡的膩子面，用鏟刀直接壓破小泡口，重新用適宜的膩子施刮起泡的面層。

　　1. Presentation of a large area of foaming putty surface, with a spade to directly break the small bubble mouth, re-use the appropriate putty to scrape the foaming surface.

　　2.特別粗糙的墻面，普通底料盡可能選擇粗的膩子。

　　2. Particularly rough wall, ordinary base material as far as possible choose thick putty.

　　3.墻面基層清算潔凈（根除松動墻面），無油污無塵灰。

　　3. Clean wall base (eliminate loosening wall), no oil and dust.

　　4.涂界面處置劑1-2遍，加強基層結實與膩子附著。

　　4. Coating interface disposal agent 1-2 times to strengthen the base and putty adhesion.

　　5.在墻體過火枯燥或風大光照激烈的環境下，先盡可能用清水潤濕墻面，待墻體無明水之后，停止膩子層的施刮。

　　5. In the environment of over-heated and dry wall or intense wind and light, wet the wall with clear water as far as possible, and stop the application of putty layer after the wall has no clear water.

　　6.呈現大面積起泡的膩子面，用鏟刀直接壓破小泡口，重新用適宜的膩子施刮起泡的面層。

　　6. Presentation of a large area of foaming putty surface, with a spade to directly break the small bubble mouth, re-use the appropriate putty to scrape the foaming surface.

　　7..膩子粉普通在攪拌平均后，靜置 10 分鐘左右，讓各種成分充沛潤濕溶解，然后用電動攪拌機再次攪拌后上墻。

　　7. Putty powder is usually stirred after an average of about 10 minutes, so that various ingredients are abundantly wetted and dissolved, and then stirred again with an electric mixer on the wall.

　　8.膩子施工時應在墻面重復批刮、推碾，讓膩子與基層充沛接觸、潮濕、浸透、擴散施工第二道或者后一道面層呈現膩子層起泡現象，應在水印消弭前用刮刀停止壓泡廢除處置，保證膩子面上不呈現氣泡。

　　8. Putty construction should be repeated batch scraping and rolling on the wall surface to make the second or last surface of the putty fully contact with the base, moist, soaking and diffusing construction present the phenomenon of putty layer bubbling. Putty surface should be removed by scraper before watermarking elimination, so as to ensure that no bubbles appear on the putty surface.

　　9.墻體預前處置：如預制模版墻頂汽泡特別嚴重的，可先停止濕水處置讓進吸水并排出空氣。待枯燥后停止界面封底處置，然后停止粗石膏底找平處置，后批刮膩子，汽泡現象會相對好很多。

　　9. Wall pre-disposal: If the top bubble of prefabricated template wall is particularly serious, wet water disposal can be stopped first to let in water absorption and exhaust air. After drying, stop the treatment of interface bottom sealing, then stop the treatment of rough gypsum bottom leveling, and finally scrape putty, the bubble phenomenon will be much better.

　　10.膩子批刮一定不要過厚，膩子的功用定位：精準裝飾找平資料。膩子更多的是起到與外表乳膠漆銜接，同時可做為外表裝飾層，批刮過厚容易起泡同時也會形成后期墻體空鼓的機率。

　　10. Putty scraping must not be too thick. Putty function positioning: precise decoration leveling data. Putty is mostly used to connect with the exterior latex paint, and can also be used as a decorative layer. It is easy to foam when scraping too thick, and it will also form the possibility of empty wall in the later period.

　　11.施工時留意天氣，空氣濕度達75%以上，墻面含水率達10%以上，防止施工。

　　11. Attention should be paid to the weather during construction. The air humidity is over 75% and the water content of the wall is over 10%, so as to prevent construction.
