采购腻子粉，非常怕销售嘴上说“耐水、不掉粉”，合同里却没一个能检测的词。真到工程报审，监理只认标准号和报告，形容词一律不过。

When purchasing putty powder, the biggest fear is that the salesperson may say 'water-resistant, no powder shedding', but there is no word in the contract that can be tested. When it comes to engineering approval, the supervisor only recognizes the standard number and report, without using any adjectives.

先按部位定类型，不混用：

First determine the type by location, do not mix:

室内干燥区：JG/T 298 里 Y 型够用，但济南回潮季长，客厅卧室也建议直接上 N 型耐水；

Indoor drying area: JG/T 298, Y-shaped is sufficient, but Jinan has a long humid season, and it is recommended to directly install N-type water-resistant in the living room and bedroom;

厨卫阳台、地下室周边：建议 N 型，浸水48h无起泡、粘结强度≥0.50MPa；

Kitchen, bathroom, balcony, basement perimeter: must be N-type, immersed in water for 48 hours without bubbles, and have a bonding strength of ≥ 0.50MPa;

外墙：走 JG/T 157，P 普通 / R 柔性 / T 弹性，真石漆前用柔性，防面层收缩扯裂；

Exterior wall: JG/T 157, P ordinary/R flexible/T elastic, flexible before real stone paint, anti surface layer shrinkage and tearing;

加气块、轻质隔墙：先轻质石膏找平（单次5–20mm），再薄刮面层腻子，不拿腻子硬补厚。

Aerated blocks and lightweight partition walls: First, level with lightweight gypsum (5-20mm per use), then apply a thin layer of putty on the surface, without using putty to harden and thicken.

询价单把“形容词”换成可检参数：

Replace the adjective with a detectable parameter in the inquiry form:

执行标准+型号（如 JG/T 298-2010 N型）；

Execution standard+model (such as JG/T 298-2010 N type);

环保：GB 18582，甲醛≤50mg/kg、VOC≤80g/L；

Environmental Protection: GB 18582, formaldehyde ≤ 50mg/kg, VOC ≤ 80g/L;

胶粉类型与添加量、填料目数、搅拌后可使用时间；

Rubber powder type and dosage, filler mesh size, and usable time after mixing;

是否含运费、税费、小批加价、补单同缸一致性。

Does it include shipping costs, taxes, small batch markups, and consistency of replenishment orders with the same cylinder.

到货验收三道关：

Three levels of acceptance upon arrival:

文件：合格证、同批号型式报告（CMA/CNAS）、十环编号可查；

Documents: Certificate of Conformity, Same Batch Type Report (CMA/CNAS), Ten Ring Number for reference;

外观：包装无破、无结块，生产日期批号一致；

Appearance: The packaging is intact and free of lumps, with consistent production date and batch number;

取样：同厂同批每10t抽3份各≥2kg，复试粘结强度、耐水、细度。

Sampling: Take 3 samples per 10 tons from the same factory and batch, each weighing ≥ 2kg, and retest the bonding strength, water resistance, and fineness.

施工前置别省：

Before construction, please save:

基层含水率＜10%、pH＜10，空鼓先凿补；

The moisture content at the grassroots level is less than 10% pH＜10， First chisel and repair the hollow drum;

单遍腻子≤1.5mm，总厚≤5mm，干透再刮下一遍；

Single layer putty ≤ 1.5mm, total thickness ≤ 5mm, dry thoroughly before scraping again;

5℃以下、湿度＞85%不施工，雨天外墙停工。

Construction will not be carried out below 5 ℃ and humidity>85%, and work on exterior walls will be suspended on rainy days.

腻子真实成本不是每吨单价，是“标准可核、大货同样、基层不出问题”三件事叠加。

The true cost of putty is not the unit price per ton, but the combination of three things: "standard approval, same bulk, and no problems at the grassroots level".
