18-Pc. Sample Pack of Mirka Fine Wet/Dry Sandpaper

Coarser grits around 80x to 220x remove material and level surfaces, while finer grits from 320x up through 2500x, like this fine wet/dry pack's range, are used for polishing and rubbing out finishes between coats.

For wood, coarser grits handle shaping and initial smoothing, while fine grits like those in the 18-pc. sample pack of Mirka fine wet/dry sandpaper (320x to 2500x) are for polishing a finish rather than removing wood.

The finest sheets in this assortment are 2500x, fine enough for polishing a finish to a high sheen rather than cutting into the wood itself.

Fine sandpaper generally starts around 320x and runs up through the very fine 2000x and 2500x grits included in this sample pack, used mainly for finish work rather than stock removal.

Before painting, a mid-to-fine grit such as 320x or 400x, both included in this pack, is generally enough to smooth the surface without leaving marks that telegraph through the paint.
