很多业主把预算砸在乳胶漆上，觉得“漆贵墙就稳”。其实济南冬夏温差大、供暖期室内外结露，真正扛潮气的不是面漆，而是腻子层。普通Y型腻子遇水汽就软化掉粉，上面再贵的漆也会跟着空鼓起皮。

Many homeowners invest their budget in latex paint, thinking that 'expensive paint makes the wall stable'. In fact, there is a large temperature difference between winter and summer in Jinan, and indoor and outdoor condensation occurs during the heating period. The real moisture carrier is not the topcoat, but the putty layer. Ordinary Y-shaped putty softens and loses its powder when exposed to water vapor, and even the most expensive paint on top will have hollowing and peeling.

挑腻子别听销售喊“环保耐水”，直接翻包装袋三行字：

Don't listen to salespeople shouting "environmentally friendly and water-resistant" when picking putty, just flip through the three lines of the packaging bag:

执行标准写 JG/T 298-2010，类型标 N型（耐水），只写“内墙通用”没标N的，基本是普通腻子。

According to the standard JG/T 298-2010, the type is marked as N-type (water-resistant), and only "universal for interior walls" is written without N, which is basically ordinary putty.

环保看 GB 18582，有十环或法国A+更好，别买散装无标签粉。

Look at GB 18582 for environmental protection, it's better to have ten rings or French A+, don't buy bulk unlabeled powder.

基层如果是加气块、旧墙翻砂，先刷一遍界面剂再批，不然粘结强度再高也粘不住浮灰。

If the base layer is made of aerated blocks or old walls that have been sandblasted, apply the interface agent first and then batch it, otherwise no matter how high the bonding strength is, it will not be able to stick the floating ash.

施工上三个工人常偷懒的点：

Three common areas where workers often slack off during construction:

第一，现场只准加水，不准掺801胶、滑石粉“调软一点”，一掺就把出厂配比毁了，后期必脱粉。

Firstly, only water is allowed to be added on site, and it is not allowed to mix 801 glue or talcum powder to make it "softer". Once mixed, the factory mix ratio will be destroyed and the powder will be removed later.

第二，单遍厚度卡在1到2毫米，两遍成活，上一遍干透再刮下一遍，赶工期连夜批三遍的，三个月必裂。

Secondly, if the thickness of a single pass is stuck at 1 to 2 millimeters, two passes will survive, and the previous pass will dry completely before scraping off again. If the batch is approved three times at night to meet the deadline, it will crack within three months.

第三，搅拌后静置3到5分钟再上墙，让胶粉充分溶胀，开放时间更长、不易留刮痕。

Thirdly, after stirring, let it stand for 3 to 5 minutes before placing it on the wall to allow the adhesive powder to fully swell, resulting in a longer opening time and less likely to leave scratches.

济南本地源头厂的好处是配方按鲁中气候调过，抗冻融和抗裂比外地通货稳。打样时拿一块刮好腻子的石膏板泡清水48小时，捞出来指甲刮不掉粉、不开泡，才算真耐水。

The advantage of a local source factory in Jinan is that the formula has been adjusted according to the climate of central Shandong, and its resistance to freezing, thawing, and cracking is more stable than that of other regions. When making a sample, soak a piece of gypsum board that has been scraped with putty in clean water for 48 hours. Only when the nail cannot scrape off the powder or open the foam can it be considered truly water-resistant.
