进入冬季，济南气温持续走低，不少装修施工队和业主在进行抹灰施工时都会犯嘀咕：天冷了水分蒸发慢，抹面砂浆还需要浇水养护吗？甚至有不少人觉得“低温能减缓干燥，不养护也没事”。其实这种想法存在明显误区，结合济南本地气候特点和砂浆施工原理来看，即便天寒，抹面砂浆的浇水养护也必不可少。今天就专门针对这个问题，给大家做一次详细科普。

　　Entering winter, the temperature in Jinan continues to drop, and many decoration construction teams and homeowners will have doubts when carrying out plastering construction: does the water evaporate slowly when it gets cold, and does the plastering mortar still need to be watered for maintenance? Many people even think that 'low temperature can slow down drying, and it's okay without maintenance'. In fact, this idea has obvious misconceptions. Based on the local climate characteristics of Jinan and the principles of mortar construction, even in cold weather, watering and curing the plastering mortar is essential. Today, we will provide a detailed science popularization specifically for this issue.

　　要搞懂为什么天冷也要养护，首先得明白养护的核心作用。很多人误以为养护只是为了防止砂浆干燥太快，其实不然，它更是保障墙面质量的关键环节。具体来说，主要有三个核心原因，这每一点都和济南的施工场景息息相关。

　　To understand why maintenance is necessary even in cold weather, one must first understand the core role of maintenance. Many people mistakenly believe that maintenance is just to prevent mortar from drying out too quickly, but in fact, it is a key link in ensuring the quality of the wall. Specifically, there are three core reasons, each of which is closely related to the construction scene in Jinan.

　　第一，保障砂浆强度达标。砂浆强度的形成，依赖于其中水泥的水化反应，而这个反应需要充足的水分和适宜的环境。济南冬季虽然干燥速度比夏季慢，但低温本身会减缓水化反应的进程。如果不进行浇水养护，砂浆中的水分会慢慢蒸发，水化反应还没完全进行就会被迫停止，最终形成的墙面强度会大打折扣，后期容易出现起砂、脱落等问题。尤其济南冬季多风，即便气温低，风力也会加速表面水分流失，进一步影响反应效果，所以浇水养护能为水化反应提供持续的水分支持，让砂浆强度稳步提升。

　　Firstly, ensure that the mortar strength meets the standard. The formation of mortar strength depends on the hydration reaction of cement, which requires sufficient moisture and suitable environment. Although the drying speed in winter in Jinan is slower than in summer, the low temperature itself will slow down the process of hydration reaction. If watering and maintenance are not carried out, the water in the mortar will slowly evaporate, and the hydration reaction will be forced to stop before it is fully carried out. The strength of the resulting wall will be greatly reduced, and problems such as sanding and peeling may occur in the later stage. Especially in winter in Jinan, it is windy, and even if the temperature is low, the wind will accelerate the loss of surface moisture, further affecting the reaction effect. Therefore, watering and curing can provide continuous moisture support for the hydration reaction and steadily improve the strength of the mortar.

　　第二，避免墙体反碱影响美观。抹面砂浆中含有一定的碱性物质，这是材料本身的特性。如果不进行浇水养护，这些碱性物质会随着水分的蒸发慢慢渗透到墙面表层，形成一层白色的碱霜，也就是大家常说的“反碱”。济南冬季室内外温差大，墙体容易出现冷凝水，会加剧反碱现象，不仅影响墙面美观，还可能影响后续涂料、壁纸的施工效果。而浇水养护能通过水分冲刷，带走部分表层的碱性物质，从源头减少反碱问题的发生。

　　Secondly, avoid the anti alkali effect on the appearance of the wall. The plastering mortar contains a certain amount of alkaline substances, which is a characteristic of the material itself. If not watered and maintained, these alkaline substances will slowly penetrate into the surface of the wall as water evaporates, forming a white alkali frost, commonly known as "anti alkali". In winter in Jinan, there is a large temperature difference between indoor and outdoor areas, which makes it easy for condensation water to occur on the walls, exacerbating the anti alkali phenomenon. This not only affects the appearance of the walls, but may also affect the construction effect of subsequent coatings and wallpapers. Watering and maintenance can remove some alkaline substances from the surface layer through water flushing, reducing the occurrence of anti alkali problems from the source.

　　第三，保证墙面平整度，助力后续施工。砂浆涂抹打磨后，表面难免会残留一些纤维丝和灰尘，这些杂质会让墙面变得粗糙。如果不清理干净，后续喷底漆时，底漆很难均匀渗透，容易出现起皮、脱落的情况。天冷时施工，砂浆干燥速度慢，恰好给了浇水清理的充足时间。通过浇水冲洗，既能彻底清除表面杂质，让墙面更光滑，还能让墙面保持适度湿润，为后续工序打下良好基础。

　　Thirdly, ensure the flatness of the wall surface to assist in subsequent construction. After applying and polishing the mortar, it is inevitable that some fibers and dust will remain on the surface, which will make the wall rough. If not cleaned thoroughly, it will be difficult for the primer to penetrate evenly during subsequent spraying, which may lead to peeling and detachment. Construction is carried out in cold weather, and the drying speed of mortar is slow, which provides ample time for watering and cleaning. By watering and rinsing, surface impurities can be thoroughly removed to make the wall smoother, and the wall can be kept moderately moist, laying a good foundation for subsequent processes.

　　这里还要提醒大家，济南冬季浇水养护也有讲究，尽量选择中午气温较高的时段进行，避免水分在墙面结冰，反而损伤砂浆层。养护频率无需过高，保持墙面湿润即可，一般持续3-5天。

　　Here we would like to remind everyone that there are also precautions for watering and maintenance in Jinan during winter. It is recommended to choose the time when the temperature is higher at noon to avoid water freezing on the wall and damaging the mortar layer. The maintenance frequency does not need to be too high, just keep the wall moist, usually lasting for 3-5 days.

　　总之，无论气温高低，抹面砂浆浇水养护都是不可或缺的环节。尤其是在济南冬季特殊的气候条件下，做好养护工作，才能保证墙面的强度、美观度和耐久性。希望这次科普能帮大家纠正认知误区，让装修施工少走弯路。

　　In short, regardless of the temperature, watering and curing the plastering mortar is an indispensable step. Especially under the special winter climate conditions in Jinan, proper maintenance work is necessary to ensure the strength, aesthetics, and durability of the walls. I hope this science popularization can help everyone correct their cognitive misconceptions and avoid detours in decoration construction.
