180 - 220 Grit: Fine. 180 – 220 grit is primarily used for the sanding finish or to sand in-between coats. It is also great for distressing! There are instances where you can use 180 to 220-grit to rough up a piece in preparation for paint, but you do not typically use these grits until after your first coat.

Wet sanding enables you to eliminate scratches that dry sandpaper may have caused without removing too much underlying material. It can also be an excellent tool for paint correction to fix any flaws or imperfections from an uneven paint job and remove any debris that may have become embedded in the paint finish.
