批完腻子第二天，墙上一片小鼓包。很多人第一反应是“腻子质量不行”，直接铲掉重来。其实起泡只是表象，根源常在基层和手法。

The next day after finishing the putty, there was a small bump on the wall. Many people's first reaction is that the quality of the putty is not good, so they simply shovel it off and start over. In fact, bubbles are just appearances, and the root often lies in the grassroots and techniques.

先看泡长什么样。

First, let's see what the bubble looks like.

刚批完就冒泡，多是基层太糙、吸水性不均，或者刮得太快把空气裹进去了。等几小时干透才爆小点，可能是粉没搅开，颗粒吸水膨胀。两种泡，解法完全不同。

Bubbling immediately after finishing the batch is often due to the rough base, uneven water absorption, or air being trapped by scraping too quickly. Wait for a few hours until it dries completely before bursting, it may be due to the powder not being stirred and the particles absorbing water expanding. The two types of bubbles have completely different solutions.

基层别“假干净”。

Don't pretend to be clean at the grassroots level.

浮灰用扫帚扫一下不算处理。混凝土墙有脱模剂、旧墙有油渍蜡层，直接批就是“贴一层壳”。正确做法：铲松动物、气枪吹灰、局部油污碱洗；吸水率高的砖墙先辊一遍界面剂，让基层“微潮不吸水”再上腻子。

Sweeping the floating ash with a broom is not considered a treatment. Concrete walls have release agents, and old walls have oil stains and wax layers. Directly applying them is like "sticking a layer of shell". Correct method: Loosen animals, blow ash with air gun, and wash local oil stains with alkali; The brick wall with high water absorption rate should first be coated with an interface agent to make the base layer "slightly damp and non absorbent" before applying putty.

搅拌有隐藏参数。

Mixing has hidden parameters.

只加清水，按比例走，搅成酸奶状，静置3–5分钟再搅一次。夏天济南干热，桶边结皮、底下还有干粉，不二次搅拌必出颗粒泡。调好的腻子别久放，1–2小时内用完，干结了绝不能再加水化开——那等于重新造一堆不稳定胶体。

Add only water, follow the ratio, stir into a yogurt like consistency, let it stand for 3-5 minutes, and stir again. In summer, Jinan is dry and hot, with crust on the edge of the bucket and dry powder at the bottom. The second stirring will inevitably produce particle bubbles. Don't leave the prepared putty for too long. It should be used up within 1-2 hours. If it dries, it must not be dissolved in water again - that is equivalent to creating a new pile of unstable colloids.

批刮厚度是核心。

Scratching thickness is the core.

单遍0.5–1mm，厚了外干内不干，收缩不一就开裂起泡。深坑别拿面层腻子糊，先用找平石膏或粗找平腻子填，再薄批。刮板角度45°左右，匀速压紧，别“拖”别“挑”。

Single pass thickness of 0.5-1mm, if it is too thick, it will dry on the outside and not dry on the inside. If the shrinkage is not uniform, it will crack and bubble. Do not apply surface putty to deep pits. First fill with leveling gypsum or rough leveling putty, and then apply a thin layer. Scraper angle is about 45 °, press firmly at a constant speed, do not "drag" or "pick".

环境比手艺更狠。

Environment is more ruthless than craftsmanship.

温度低于5℃、湿度超85%、雨天前后24小时，别硬干。济南换季早晚湿差大，通风别对着墙吹，表面结皮里面潮，后期准脱粉。用电暖器烘更糟，外脆内湿。

If the temperature is below 5 ℃, the humidity exceeds 85%, and it rains for 24 hours before and after, do not dry it hard. There is a large difference in humidity between morning and evening during the seasonal change in Jinan. Do not blow against the wall for ventilation, as the surface may crust and the inside may become damp, and the powder may peel off later on. Heating with an electric heater is worse, it's brittle on the outside and wet on the inside.

干透判断别靠手摸。

Don't rely on your hands to make a thorough judgment.

看颜色均匀发白、指甲划无湿痕、靠尺测平整度≤3mm/2m。没干透就打磨，粉尘粘回表面；没干透就刷漆，水汽闷在层间，半年后起皮。

Check if the color is uniform and white, if there are no wet marks on the nails, and if the flatness is measured with a ruler, it should be ≤ 3mm/2m. Polish before it dries completely, and dust will stick back to the surface; Brushing the paint before it dries completely will cause moisture to accumulate between the layers, resulting in peeling after six months.

验收三件事：

Acceptance of three things:

灯侧照无气泡阴影、手擦不掉粉、阴阳角顺直。出问题先分型再动手，别一上来就铲墙。

The side lighting of the lamp has no bubble shadows, the powder cannot be wiped off by hand, and the internal and external corners are straight. When there is a problem, type it first and then take action, don't just shovel the wall as soon as you come up.

腻子这东西，七分在基层，三分在批法。泡不是敌人，是墙面在报错。

Putty is 70% in the base layer and 30% in the batch method. Bubble is not an enemy, it's the wall reporting an error.
