There are several common misunderstandings in the use of sandpaper. How can we avoid these problems and maximize the use of sandpaper? The following is a brief explanation:
1. The worn sandpaper is equivalent to the sandpaper with a higher grade.
Old sandpaper means reduced cutting efficiency and increased heat generation. If you feel that the sanding speed is too slow, change to new sandpaper, or reduce it by one grade.

2. The harder you press on the sandpaper, the faster it sands.
Pressure will only increase the wear and heat of the sandpaper, and even burn the wood. Generally speaking, sanding only requires very light pressure, letting the sandpaper and tools do the hard work. This is easy and extends the life of the sandpaper, and the speed is not slow at all.
3. Use the same grade of sandpaper to the end.
Many beginners only buy one size of sandpaper, which is very inefficient.
4. Polishing is a long and boring process.
If you have this feeling, it is generally because you can't see obvious progress in the sanding process. This means that the sandpaper you are using is too high or too old and needs to be replaced.
