装修新房时，很多人都急着入住，刮完腻子后就开始盘算搬家时间，网上常说“7-10天就能住”，但实际情况远不止看天数这么简单。今天就把新房刮腻子后的入住注意事项讲透，帮你避开健康隐患，既不盲目拖延，也不冒险早住。

　　When decorating a new house, many people are in a hurry to move in. After applying putty, they start calculating their moving time. It is often said online that they can live in 7-10 days, but the actual situation is much more than just looking at the number of days. Today, I will explain the precautions for moving into a new house after applying putty, to help you avoid health hazards. You will neither blindly delay nor take the risk of staying early.

　　首先明确核心：刮完腻子后建议等待7-10天再入住，这个时间是基于常规环境下的干燥周期——腻子上墙后需要逐步失水固化，前3天是快速干燥阶段，表面会变得干爽不粘手；后续4-7天则是深层干燥期，内部水分慢慢蒸发，腻子才能完全硬化，形成稳定的墙面结构。如果没等腻子干透就入住，一方面墙面容易吸附空气中的潮气，导致返潮发霉，甚至出现腻子层空鼓、脱落；另一方面，未干透的腻子会持续释放游离甲醛、VOC等有害物质，加上室内通风可能受限，有害物质浓度超标，会直接影响居住者的呼吸道健康，尤其对老人、小孩和孕妇更不友好。

　　Firstly, clarify the core: After applying putty, it is recommended to wait for 7-10 days before moving in. This time is based on the drying cycle in a regular environment - the putty needs to gradually lose water and solidify after being applied to the wall. The first 3 days are the rapid drying stage, and the surface will become dry and non stick to the hands; The next 4-7 days are the deep drying period, during which the internal moisture slowly evaporates before the putty can fully harden and form a stable wall structure. If you move in before the putty dries completely, on the one hand, the wall is prone to absorbing moisture from the air, causing it to become damp and moldy, and even resulting in hollowing and peeling of the putty layer; On the other hand, unfinished putty will continue to release harmful substances such as free formaldehyde and VOCs. In addition, indoor ventilation may be limited, and the concentration of harmful substances may exceed the standard, which will directly affect the respiratory health of residents, especially unfriendly to the elderly, children, and pregnant women.

　　但7-10天只是参考值，实际入住时间必须结合环境湿度调整。如果装修时恰逢梅雨季、回南天，或者新房位于一楼、地下室等湿气较重的区域，空气湿度大，腻子干燥速度会明显变慢，7-10天可能只完成表面干燥，内部仍有残留水分。这种情况下，必须延长干燥时间，可能需要15天甚至更久，直到用手按压墙面无凹陷、墙面颜色均匀（没有深浅不一的潮湿痕迹）为止。反之，如果是干燥的秋冬季节，室内开了暖气或除湿机，腻子干燥速度会加快，可能7天左右就能达到入住标准，但仍需通过实际检查确认，不能单纯看天数。

　　But 7-10 days is only a reference value, and the actual check-in time must be adjusted according to the environmental humidity. If the decoration coincides with the rainy season, returning to the southern sky, or if the new house is located in areas with high humidity such as the first floor or basement, the air humidity will be high, and the drying speed of putty will significantly slow down. It may only take 7-10 days to complete surface drying, and there may still be residual moisture inside. In this case, it is necessary to extend the drying time, which may take 15 days or even longer, until the wall is pressed by hand without any dents and the color of the wall is uniform (without varying shades of moisture marks). On the contrary, if it is the dry autumn and winter season and the indoor heating or dehumidifier is turned on, the drying speed of putty will be accelerated. It may take about 7 days to reach the occupancy standard, but it still needs to be confirmed through actual inspection and cannot be simply based on the number of days.

　　比等待时间更重要的，是入住前的通风和空气质量检测。刮完腻子后，每天要保证开窗通风4-6小时，让空气流通带走挥发的有害物质和潮气；如果新房通风条件差，可以配合空气净化器、风扇加速空气循环。入住前最好用甲醛检测仪自测一下，确保室内甲醛浓度低于0.08mg/m?，TVOC浓度低于0.6mg/m?，只有空气质量达标，才能放心入住。千万别觉得“腻子看着干了就没事”，很多有害物质是无色无味的，仅凭感官判断很容易忽略风险。

　　More important than waiting time is ventilation and air quality testing before check-in. After applying putty, it is necessary to ensure that the windows are ventilated for 4-6 hours every day to allow air circulation and remove harmful substances and moisture that have evaporated; If the ventilation conditions of the new house are poor, air purifiers and fans can be used to accelerate air circulation. It is best to self test with a formaldehyde detector before check-in to ensure that the indoor formaldehyde concentration is below 0.08mg/m? ， Is the TVOC concentration below 0.6mg/m? Only when the air quality meets the standard can you stay with peace of mind. Don't think that "putty is fine just because it looks dry". Many harmful substances are colorless and odorless, and it is easy to ignore the risks based solely on sensory judgment.

　　还要提醒大家：如果新房刮完腻子后还计划刷底漆和面漆，入住时间需要重新计算——刷完漆后同样需要7-10天的干燥和通风期，因为油漆中也会含有挥发性物质，必须等漆膜完全固化、有害物质充分释放后再入住。而且刷漆后的通风要更注意，避免强风直吹墙面导致漆膜开裂，可采用“间歇性通风”的方式，每天分时段开窗。

　　Also, it should be reminded that if a new house plans to apply primer and topcoat after applying putty, the occupancy time will need to be recalculated - a drying and ventilation period of 7-10 days is also required after painting, as the paint also contains volatile substances. It is necessary to wait for the paint film to fully cure and harmful substances to be fully released before moving in. Moreover, more attention should be paid to ventilation after painting to avoid strong winds blowing directly onto the wall, which may cause cracking of the paint film. The "intermittent ventilation" method can be used, with windows opened at different times every day.

　　另外，入住后的初期也要保持室内通风，尤其是前1-2个月，避免因室内湿气积聚导致墙面返潮。如果入住后发现墙面出现起皮、发霉，大概率是腻子未干透就入住，或是通风不到位，此时要及时开窗通风，严重的话可能需要重新处理墙面，反而得不偿失。

　　In addition, indoor ventilation should be maintained in the early stages after check-in, especially in the first 1-2 months, to avoid wall moisture accumulation due to indoor humidity. If peeling or mold is found on the wall after moving in, it is likely that the putty has not dried completely before moving in, or the ventilation is not in place. At this time, it is necessary to open the window for ventilation in a timely manner. In severe cases, the wall may need to be reprocessed, which may not be worth the loss.

　　总结下来，新房刮完腻子7-10天入住的说法，是建立在“环境干燥、充分通风、空气质量达标”基础上的，不能生搬硬套。装修是为了住得舒心，与其急着搬家，不如多花几天时间做好干燥和通风，用科学的方式确认安全，才能真正实现安心入住。如果对墙面干燥程度、空气质量检测有疑问，也可以咨询专业的装修师傅，根据新房的具体情况调整入住时间，别让心急埋下健康隐患。

　　In summary, the statement that it takes 7-10 days to move in after applying putty to a new house is based on the principles of "dry environment, sufficient ventilation, and air quality standards", and cannot be blindly applied. Decoration is for a comfortable stay. Instead of rushing to move, it's better to spend a few more days doing a good job of drying and ventilation, and confirm safety in a scientific way to truly achieve a peaceful stay. If you have any questions about the dryness of the walls or air quality testing, you can also consult a professional decorator and adjust the check-in time according to the specific situation of the new house, so as not to be anxious and bury health hazards.
