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、墻面膩子粉別刮太厚：因為室內空氣干燥，失水較快，很容易造成空鼓、開裂、墻面不平整現象。

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、干燥季節時，晚上一定要關緊門窗，防止墻面吸收空氣中水分，增加了墻面結構力，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、如果墻面出現部分下凹狀況，用石膏粉加乳白漆調和修補墻面，這樣便于加速干燥。當墻面出現較大裂縫時，局部的地方雙貼布條后再刮膩子粉。

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、批刮完二遍老萬寶膩子粉后，墻面泛白、無水漬印時立即打磨。干透越久結構力越高，打磨難度大。

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、墻面膩子處理選溫度相對較高時段進行，這樣可以防止新刮的膩子凍結。待一遍膩子完全干透后，再刮二遍，二遍膩子完全干透后，再用細砂紙仔細打磨。

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、打磨膩子時施工人員必須做好防護措施。帶好口罩、手套、避免皮膚不適。

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

刮膩子底材處理一般要求基層表面在披刮膩子前必須堅實牢固，不應有起砂、裂縫、疏松等缺陷。如果墻體平整，建議不使用膩子;若使用膩子，易薄批而不宜厚刷;內墻膩子粉應見水不軟化膨脹、不能手抹起粉。對膩子粉的要求除了易批易打磨外，還應具備較好的強度和持久性。對于外墻，廚房和衛生間，其對膩子粉的要求應具備更好的粘結性，粘結持久性及耐水性。膩子粉干后，要用砂紙打磨平整，再用濕布將膩子上的浮灰抹去，并盡快涂漆。

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.
