内墙翻新再刮腻子之后发黄怎么回事呢？
内墙翻新再刮腻子之后发黄怎么回事呢？这与墙体老旧以及使用了重钙腻子粉有关：
What's the matter with yellowing after interior wall renovation and putty? This is related to the old wall and the use of heavy calcium putty powder
旧墙腻子使用了大量的PVA胶水，胶水老化分解，产生不饱和酸，不饱和酸与腻子中钙离子反应，生成相应黄色的钙盐。
A lot of PVA glue is used in old wall putty. The glue is aged and decomposed to produce unsaturated acid, which reacts with calcium ion in putty to produce corresponding yellow calcium salt.
济南腻子粉分享其解决方法：
Jinan putty powder shares its solution:
1、用环保胶水滚涂两遍，彻底干透后，再行施刮睡宝牌环保水性内墙腻子；
1. Roll twice with environmental glue, dry thoroughly, and then apply Shuibao brand environmental water-based interior wall putty;
2、用睡宝白色封闭底漆滚涂两道，彻底干透后，再批刮腻子。
2. Roll two coats of sleeping treasure white sealing primer, dry thoroughly, and then apply putty.
3、全部采用膏状腻子施工，或用板材腻子施工。

果用乳胶漆刷墙，除去变黄部分，重新批刮腻子，按照正常的刷墙步骤做：
If the wall is painted with latex paint, the yellowing part is removed, and the putty is applied again
1、先刮腻子，腻子主要作用是墙面衬底，找平的作用，（做两到三遍，每遍都要等完全干透后再做下遍）。
1. The main function of putty is the wall substrate, leveling (do two to three times, each time must wait until completely dry before the next time).
2、砂纸打磨平整。
