腻子粉是装修中非常容易被忽视的材料，全屋用量超一吨，藏在墙里看不见，却是甲醛释放非常久的材料之一。很多人花几万块买环保家具，非常后却栽在几块钱一袋的腻子粉上，这事儿真不是段子。

Putty powder is the most easily overlooked material in decoration, with a total usage of over one ton in the whole house. It is hidden in the walls and cannot be seen, but it is one of the materials that releases formaldehyde for the longest time. Many people spend tens of thousands of yuan on eco-friendly furniture, only to end up with a bag of putty powder that costs only a few yuan. This is really not a joke.

选购第一关：环保标准，只认两个编号

First level of purchase: Environmental standards, only two identification numbers are recognized

别信商家口头说的“环保无毒”，一切以包装上的印刷为准。建议符合GB18582-2020《室内装饰装修材料 内墙涂料中有害物质限量》国家标准，同时符合JG/T298-2010《建筑室内用腻子》行业标准，这才是真正的合格产品。有中国环境标志认证的更好，环保等级更高，适合有老人小孩的家庭。

Don't believe what merchants say verbally as' environmentally friendly and non-toxic ', everything should be based on the printing on the packaging. It must comply with the national standard GB18582-2020 "Limits of Hazardous Substances in Interior Decoration Materials and Interior Wall Coatings" and the industry standard JG/T298-2010 "Putty for Interior Use in Buildings" to be a truly qualified product. Having a Chinese environmental label certification is better, with higher environmental protection levels, suitable for families with elderly and children.

选购第二关：类型选对，普通型还是耐水型

Second level of selection: Choose the right type, regular or water-resistant

看腻子包装背面的执行标准，后面的字母代表类型：“Y”是普通型，“N”是耐水型，“R”是柔性。厨房、卫生间、阳台这些常年潮湿的区域，建议选带“N”标识的耐水腻子。普通腻子遇水就粉化，用不了两年就会掉皮、发霉。耐水腻子虽然价格贵一点，但能节省30%以上的涂料，受潮后不容易开裂，长期来看性价比更高。

According to the execution standards on the back of the putty packaging, the letters behind represent the types: "Y" for ordinary type, "N" for water-resistant type, and "R" for flexible type. The kitchen, bathroom, balcony and other damp areas must be selected with water-resistant putty marked with an "N" symbol. Ordinary putty will turn into powder when it comes into contact with water, and will peel off and mold within two years of use. Although water-resistant putty is a bit more expensive, it can save more than 30% of the coating, and is less likely to crack when exposed to moisture, making it more cost-effective in the long run.

选购第三关：保质期只有6-12个月，过期绝对不能要

Third level of purchase: The shelf life is only 6-12 months, and expiration is absolutely unacceptable

腻子粉的粘结力全靠胶粉，过期后胶粉失效，刮上墙的腻子100%会空鼓、脱落。材料进场第一时间检查生产日期，哪怕只差一个月也别用。

The bonding strength of putty powder relies entirely on adhesive powder. After expiration, the adhesive powder will become ineffective, and 100% of the putty scraped onto the wall will become hollow and fall off. Check the production date as soon as the materials enter the site, even if it is only one month away, do not use them.

施工非常丧良心操作：往腻子粉里加胶水

The most heartless operation in construction: adding glue to putty powder

合格的成品腻子粉，加水就能直接用，不需要加明显东西。师傅加胶水，要么是用了劣质腻子粉粘结力不够，要么是图省事好施工。但胶水是甲醛的头号来源，加一桶胶水，全屋甲醛超标几倍都不止。只要发现师傅往腻子粉里倒胶水，立刻停工换人，没得商量。

Qualified finished putty powder can be used directly with water without adding anything. The master added glue, either because he used inferior putty powder with insufficient bonding strength, or because he wanted to save time and facilitate construction. But glue is the number one source of formaldehyde, adding a bucket of glue, the formaldehyde in the whole house exceeds the standard several times. As long as the master pours glue into the putty powder, immediately stop work and replace the person without any negotiation.

施工找平顺序不能乱

The construction leveling sequence cannot be disorderly

先用轻质石膏做全屋粗找平，误差超过3mm的地方先找顺；门套边、柜子边建议用红外线靠尺精找平；非常后再刮2-3遍腻子，每遍都要等完全干透再刮下一遍。

First, use lightweight gypsum to make a rough leveling of the entire house, and smooth out any areas where the error exceeds 3mm; The edges of the door frame and cabinet must be precisely leveled with an infrared ruler; Finally, apply 2-3 coats of putty, and wait for each coat to completely dry before applying the next coat.
