Which grit should you use for which work on the sandpaper? Surely you have already faced this question when you dealt with building- and have employed handicraft instructions. The grain size is given in mesh. The larger the grain size, the finer the sandpaper.
What grain sizes are there and what for?
- Coarse sandpaper is available in grain sizes between 6 and 30. You can use it for the rough removal of layers of paint and glue. Planks can be pre-sanded so easily.
- Medium grain sizes are 36 to 80 and are used for pre-sanding raw, untreated wooden surfaces. Door frames, window- and door frames can also be treated with this grain.
- With the fine grain size of 100 to 180 you can sand raw wooden surfaces very finely. If you want to paint something, you can pre-sand with this grit.
- It is best to treat watered, lacquered or primed surfaces with the very fine grain size of 220 to 1000. A very fine grain is also used for bodywork.

Important information about working with sandpaper
- Always start with a small grain size and gradually increase the grain size.
