I am looking for the lowest grit sandpaper that will remove wood the fastest.
I found this, but could find no P12 sandpaper.
Extra Coarse
This highly coarse sandpaper grit ensures expedited removal of all kinds of material. Because of the roughness, extra coarse sandpaper is used for the initial round of sanding on hardwood flooring. As per the FEPA standards, the sandpaper grit sizing is denoted by P30, P36, P12, and P16, while the CAMI standards denote the classes as 24, 30, or 36. The average diameter of the sandpaper grit particles can range anywhere between 530 to 1815 micrometers.
