Common misconceptions in the use of sandpaper

1. Worn sandpaper is equivalent to high-grade sandpaper

Old sandpaper means a decrease in cutting efficiency and an increase in heat generation. If you feel that the polishing speed is too slow, replace it with a new sandpaper or lower it by one.

2. The harder you press on the sandpaper, the faster it will be polished

Pressure will only increase the wear and heat of sandpaper, and even burn the wood. Generally speaking, polishing only requires light pressure, making sandpaper and tools laborious, which is easy and extends the lifespan of sandpaper, and the speed is not slow at all.

3. Use a numbered 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 due to the lack of noticeable progress during the polishing process. This indicates that the sandpaper number you are using is too high or too old, and you need to replace it with a new one.
