In the dry season, the air humidity is relatively high. The putty powder manufacturer summarized what should be paid attention to when applying putty in the dry season.

1、墙面腻子粉别刮太厚：因为室内空气干燥，失水较快，很容易造成空鼓、开裂、墙面不平整现象。

1. Do not scrape the wall putty powder too thick: because the indoor air is dry and the water loss is fast, it is easy to cause hollowing, cracking and uneven wall surface.

2、干燥季节时，晚上一定要关紧门窗，防止墙面吸收空气中水分，增加了墙面结构力，不宜打磨。

2. In dry season, the doors and windows must be closed at night to prevent the wall from absorbing moisture in the air, which increases the structural force of the wall and is not suitable for polishing.

3、如果墙面出现部分下凹状况，用石膏粉加乳白漆调和修补墙面，这样便于加速干燥。当墙面出现较大裂缝时，局部的地方双贴布条后再刮腻子粉。

3. If the wall is partially concave, repair the wall with gypsum powder and milky white paint, so as to accelerate drying. In case of large cracks on the wall, apply putty powder after double pasting cloth strips in local places.

4、批刮完二遍老万宝腻子粉后，墙面泛白、无水渍印时立即打磨。干透越久结构力越高，打磨难度大。

4. After the old Wanbao putty powder is scraped twice, the wall is white and there is no water stain, and it shall be polished immediately. The longer the drying, the higher the structural force and the greater the grinding difficulty.

5、墙面腻子处理选温度相对较高时段进行，这样可以防止新刮的腻子冻结。待一遍腻子完全干透后，再刮二遍，二遍腻子完全干透后，再用细砂纸仔细打磨。

5. The treatment of wall putty should be carried out at relatively high temperature, which can prevent the new putty from freezing. After the first putty is completely dry, scrape it twice. After the second putty is completely dry, polish it carefully with fine sandpaper.

6、打磨腻子时施工人员必须做好防护措施。带好口罩、手套、避免皮肤不适。

6. When polishing putty, construction personnel must take protective measures. Wear masks and gloves to avoid skin discomfort.

刮腻子底材处理一般要求基层表面在披刮腻子前必须坚实牢固，不应有起砂、裂缝、疏松等缺陷。如果墙体平整，建议不使用腻子;若使用腻子，易薄批而不宜厚刷;内墙腻子粉应见水不软化膨胀、不能手抹起粉。对腻子粉的要求除了易批易打磨外，还应具备较好的强度和持久性。对于外墙，厨房和卫生间，其对腻子粉的要求应具备更好的粘结性，粘结持久性及耐水性。腻子粉干后，要用砂纸打磨平整，再用湿布将腻子上的浮灰抹去，并尽快涂漆。

The treatment of puttying substrate generally requires that the base surface must be solid and firm before puttying, and there shall be no defects such as sanding, cracks, looseness and so on. If the wall is flat, it is recommended not to use putty; If putty is used, it is easy to apply it thin rather than thick; The putty powder of interior wall shall not soften and expand in the presence of water and cannot be applied by hand. The putty powder shall not only be easy to batch and polish, but also have good strength and durability. For exterior walls, kitchens and toilets, the requirements for putty powder shall have better adhesion, adhesion durability and water resistance. After the putty powder is dry, it shall be polished with sandpaper, and then the floating ash on the putty shall be wiped off with a wet cloth and painted as soon as possible.
