Putty powder composed of talcum powder, base material, filler, water, auxiliary agent and glue is a kind of building decoration material. Putty powder can be used for wall surface repair and smoothing, and it is used for brushing and painting wallpaper. Putty powder is divided into exterior wall putty powder and interior wall putty powder, then let Xiaobian take everyone to look at the introduction of the relevant content of the difference between the exterior wall putty powder and the interior wall putty powder .
1. The main difference between the interior wall putty and the outer wall putty is the different ingredients.
2, the interior wall putty is based on double fly powder (large white powder) as the main raw material, so its water resistance and hardness are relatively poor.
3, the outer wall putty is based on white cement, so its water resistance and hardness is much stronger.
4, the thickness of the interior wall putty and the external wall putty (granules) is not much different, it is difficult to distinguish only the hand touch.
5. The interior wall putty and the exterior wall putty are not much different in terms of environmental protection, because the environmental performance of the raw materials used is basically the same.
6. The outer wall putty is mainly high in strength. It is not as good as the internal wall putty when it is scraped on the wall. It is not easy to be polished after drying.
7, the main raw material of the interior wall putty is white powder, the main raw material of the outer wall putty is white cement, the difference between white powder and white cement can be too big.
8, no matter how the white powder is formed, the strength is very low after drying, the nail can be used to scrape the traces, and after the water will appear softening again.
9. After the white cement is hydrated and solidified, the strength is very high. Even the hammer can not knock the traces, and it will not hydrate or soften again after encountering the water.
10, performance: the interior wall putty is delicate, but when it meets the water, it is empty and peeled off. The outer wall putty is rough, but it is waterproof.
11, the difference between the interior wall putty and the outer wall putty is: the outer wall putty has a certain waterproof, not afraid of rain, it is an oily putty, both internal and external walls can be used. The interior wall putty is not waterproof and cannot be used on the exterior wall.
12, the composition is different, the external wall putty powder is mostly white cement, the interior wall putty powder is mainly based on old powder and talcum powder.
13. Different water resistance, the outer wall putty powder has very good water resistance after drying, mainly due to different cement content or different rubber powder content.
14. The outer wall putty powder has high cement content, so it is generally alkaline.
15, the interior wall putty powder is relatively delicate, to meet the characteristics of the interior wall construction; grinding is also better than the outer wall putty powder.
16. The outer wall putty powder is more sturdy; the construction is relatively difficult.
How about, I read the introduction of the difference between the external wall putty powder and the interior wall putty powder, and I also learned a lot about the difference between the exterior wall putty powder and the interior wall putty powder.
