Putty powder is a material for leveling the wall and is the base for further painting. Therefore, putty powder is related to the flatness of the wall. It is very important to choose good putty powder. How to distinguish the quality of putty powder can be identified from the following angles.

1 Look at the powder shedding situation

Poor quality putty: Use your fingers to gently rub the surface of the sample coated with inferior putty, and a lot of putty powder will be on your fingers.
High-quality putty: Use your fingers to gently rub the surface of the sample coated with high-quality putty. And your fingers are very clean. The putty has no powder shedding at all.

2 Look at the putty after being dissolved in water

Poor quality putty: Use your hands to gently rub the surface of the sample after water washing, and your fingers will be stained with a lot of putty dissolved by water.
High-quality putty: Even if you rub the sample after water washing repeatedly with your hands, your hands are clean.

3 Look at the surface changes after water washing

Poor quality putty: After water washing, the inferior putty sample will quickly bubble and peel.
High-quality putty: Wash the high-quality putty sample with the same water flow intensity. And there will be no abnormality on the putty surface.

4 Look at the cement surface after pulling

Poor-quality putty: After pulling, observe the fracture surface of the putty. The fracture surface of the inferior putty appears on the surface of one of the cement blocks, which means that the putty on the cement surface has been pulled out.
High-quality putty: The fracture surface of the high-quality putty appears in the middle layer of the putty itself, and the two cement surfaces are still stuck with putty.
