济南的气候特点对腻子粉施工影响显著，其施工条件的把控和调配方法的科学性，直接关系到墙面基层处理的质量。结合当地四季温差大、夏季多雨、冬季干燥的气候特征，需从环境要求、基层处理、材料调配等方面规范操作。

　　The climate characteristics of Jinan have a significant impact on the construction of putty powder, and the scientific control of construction conditions and mixing methods directly affect the quality of wall base treatment. Considering the climate characteristics of large temperature differences throughout the year, rainy summers, and dry winters in the local area, it is necessary to standardize operations in terms of environmental requirements, grassroots treatment, and material allocation.

　　一、施工条件的关键要素

　　1、 Key elements of construction conditions

　　1. 温湿度控制

　　1. Temperature and humidity control

　　济南春季多风干燥，夏季高温多雨，施工时需将环境温度控制在 5-35℃之间。温度过低会导致腻子粉凝结缓慢，影响固化强度；高于 35℃则水分蒸发过快，易出现干裂。空气相对湿度需保持在 40%-80%，梅雨季施工时可借助除湿机降低湿度，避免墙面返潮导致腻子层起泡；冬季干燥时，可在施工区域适当洒水增湿，但需确保墙面无明水。

　　Jinan is windy and dry in spring, and hot and rainy in summer. During construction, the ambient temperature should be controlled between 5-35 ℃. Low temperature can cause slow solidification of putty powder, affecting the curing strength; If the temperature is higher than 35 ℃, the water evaporates too quickly and is prone to drying and cracking. The relative humidity of the air should be maintained at 40% -80%. During construction in the rainy season, dehumidifiers can be used to reduce the humidity and avoid wall moisture from causing bubbles in the putty layer; When it is dry in winter, it is advisable to sprinkle water appropriately in the construction area to increase humidity, but it is necessary to ensure that there is no visible water on the wall.

　　2. 基层处理标准

　　2. Grassroots treatment standards

　　施工前墙面基层必须坚实平整，无浮灰、油污、空鼓等缺陷。先用铲刀清除残留的砂浆块和疏松表层，再用细砂纸打磨至表面光滑。对于济南老房常见的墙面返碱现象，需用草酸溶液擦拭中和，待干燥后再刷一遍界面剂，增强腻子与基层的附着力。墙面含水率需控制在 10% 以下，可通过含水率检测仪检测，潮湿区域需提前通风干燥 3-5 天。

　　Before construction, the wall base must be solid and flat, without defects such as floating ash, oil stains, hollowing, etc. First, use a scraper to remove any remaining mortar blocks and loose surface, and then polish with fine sandpaper until the surface is smooth. For the common phenomenon of wall alkali return in old houses in Jinan, oxalic acid solution should be used to wipe and neutralize it. After drying, the interface agent should be brushed again to enhance the adhesion between the putty and the base layer. The moisture content of the wall should be controlled below 10%, which can be detected by a moisture content detector. Wet areas should be ventilated and dried for 3-5 days in advance.

　　二、腻子粉的科学调配方法

　　2、 Scientific blending method of putty powder

　　1. 材料配比与搅拌技巧

　　1. Material ratio and mixing techniques

　　普通内墙腻子粉与水的配比通常为 1:0.3-0.4（重量比），具体需根据产品特性微调。调配时先将清水倒入干净容器，再缓慢加入腻子粉，边倒边用电动搅拌器匀速搅拌，搅拌时间不少于 3 分钟，确保形成均匀无颗粒的膏状。静置 5 分钟后再次搅拌，可增强腻子的粘稠度和均匀性，避免因搅拌不匀导致墙面出现斑驳。

　　The ratio of ordinary interior wall putty powder to water is usually 1:0.3-0.4 (weight ratio), which needs to be adjusted according to product characteristics. When mixing, first pour clean water into a clean container, then slowly add putty powder. While pouring, use an electric mixer to stir at a constant speed for no less than 3 minutes to ensure the formation of a uniform and particle free paste. After standing still for 5 minutes, stir again to enhance the viscosity and uniformity of the putty, avoiding the appearance of mottled walls due to uneven mixing.

　　2. 特殊场景的调配调整

　　2. Adjustment and deployment for special scenarios

　　针对济南外墙或潮湿环境（如厨房、卫生间附近墙面），可在调配时加入适量防水剂，比例约为腻子粉重量的 3%-5%，提升腻子层的抗渗性。对于需要增强附着力的新旧墙面交界处，可掺入 5%-8% 的白乳胶，搅拌均匀后使用，但需注意白乳胶的用量不宜过多，否则会导致腻子层过硬易开裂。

　　For exterior walls or damp environments in Jinan (such as walls near kitchens and bathrooms), an appropriate amount of waterproofing agent can be added during preparation, with a proportion of about 3% -5% of the weight of putty powder, to enhance the impermeability of the putty layer. For the junction of new and old walls that require enhanced adhesion, 5% -8% white latex can be added and mixed evenly before use. However, it should be noted that the amount of white latex should not be too much, otherwise it will cause the putty layer to become too hard and prone to cracking.

　　3. 施工过程的注意事项

　　3. Precautions during the construction process

　　调配好的腻子需在 2 小时内用完，避免因济南干燥的空气导致其凝固失效。施工时需分两遍刮涂，第一遍厚度控制在 1-2 毫米，主要用于填补墙面缝隙和不平处，待完全干燥（夏季约 6-8 小时，冬季需 12-24 小时）后用砂纸打磨平整；第二遍厚度 0.5-1 毫米，追求表面光滑细腻。两遍施工间隔需根据天气调整，阴雨天可延长干燥时间，确保前一层完全固化。

　　The prepared putty should be used up within 2 hours to avoid solidification failure caused by the dry air in Jinan. During construction, it is necessary to scrape and apply in two layers. The thickness of the first layer should be controlled at 1-2 millimeters, mainly used to fill the gaps and unevenness of the wall. After it is completely dry (about 6-8 hours in summer and 12-24 hours in winter), it should be sanded flat with sandpaper; The second layer has a thickness of 0.5-1 millimeter, aiming for a smooth and delicate surface. The interval between two construction runs needs to be adjusted according to the weather, and the drying time can be extended on rainy days to ensure that the previous layer is completely cured.
