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. 搅拌不平均。

　　1. Uneven stirring.

　　2. 腻子加水过多，拌得太湿。

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

　　3.基层含水率过高，同时密度太大或太小。由于含有丰厚的空隙。腻子含水率高，因此不透气，容易使施工过程中，腻子粉层的下部含有空气，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.基面存在细小孔洞，刮涂时腻子粉将孔洞内空气挤压，挤压后的空气反弹变成气泡。

　　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.密封性较好的基面透气性较差。

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

　　6.单层批刮过厚，腻子层的空气没有完整挤压出来。

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

　　7.基层过于粗糙，有细小孔洞。批刮时腻子将孔洞内空气紧缩，之后空气压力反弹构成气泡。

　　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.基底过于粗糙，没有打磨平整，腻子施工过程中批墙速渡过快，招致腻子粉不平均惹起的。

　　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、高标号混凝土等密闭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.高温施工时腻子易产生气泡。

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

　　11.基材吸水量过低。招致腻子批刮时相对保水时间过长而使腻子在墙上长期处于浆料态而不干，使气泡易产生。

　　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.墙面太湿润的缘故。

　　12. The wall is too wet.

　　13..不容易被泥刀挤压出！而产生针孔状毛孔，就是为什么工程上批刮模板顶比墙体气泡更多的缘由，墙体吸水量大，而模板顶吸水量极低。

　　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..纤维素添加量过大。

　　14. Excessive cellulose addition.

　　15.施工一段时间后，才在外表呈现的爆裂起泡，主要是搅拌不平均形成的，浆体中含有来不及溶解的粉状颗粒，施工后，大量吸收水分，溶胀构成爆裂。

　　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.

　　处理办法：

　　Approaches:

　　1.呈现大面积起泡的腻子面，用铲刀直接压破小泡口，重新用适宜的腻子施刮起泡的面层。

　　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.特别粗糙的墙面，普通底料尽可能选择粗的腻子。

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

　　3.墙面基层清算洁净（根除松动墙面），无油污无尘灰。

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

　　4.涂界面处置剂1-2遍，加强基层结实与腻子附着。

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

　　5.在墙体过火枯燥或风大光照激烈的环境下，先尽可能用清水润湿墙面，待墙体无明水之后，停止腻子层的施刮。

　　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.呈现大面积起泡的腻子面，用铲刀直接压破小泡口，重新用适宜的腻子施刮起泡的面层。

　　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..腻子粉普通在搅拌平均后，静置 10 分钟左右，让各种成分充沛润湿溶解，然后用电动搅拌机再次搅拌后上墙。

　　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.腻子施工时应在墙面重复批刮、推碾，让腻子与基层充沛接触、潮湿、浸透、扩散施工第二道或者后一道面层呈现腻子层起泡现象，应在水印消弭前用刮刀停止压泡废除处置，保证腻子面上不呈现气泡。

　　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.墙体预前处置：如预制模版墙顶汽泡特别严重的，可先停止湿水处置让进吸水并排出空气。待枯燥后停止界面封底处置，然后停止粗石膏底找平处置，后批刮腻子，汽泡现象会相对好很多。

　　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.腻子批刮一定不要过厚，腻子的功用定位：精准装饰找平资料。腻子更多的是起到与外表乳胶漆衔接，同时可做为外表装饰层，批刮过厚容易起泡同时也会形成后期墙体空鼓的机率。

　　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.施工时留意天气，空气湿度达75%以上，墙面含水率达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.
