Mirka Coarse Wet/Dry Sandpaper

For this coarse range, lower grits like 80x to 120x suit initial shaping and stripping, mid grits like 150x to 180x smooth paint, lacquer and composite surfaces, and the finer 220x to 240x sheets prepare a surface for finishing or refine a sharpening edge when used wet with water or oil.

This range isn't intended for bare wood sanding: it's built for wet sanding paints, lacquers, plastics, composites and non-ferrous metal, and also works well for sharpening tools when used with water or oil as a lubricant.

The finest sheet in this coarse range is 240x, suited to fine surface prep before finishing; anything smoother than that calls for a dedicated fine or extra-fine sandpaper line.

A mid-range grit like 150x to 180x works well to key a surface before painting, since it's coarse enough to help paint or lacquer adhere without leaving deep scratches under the finish.

Yes, it's designed for wet sanding, and its latex-impregnated backing resists tearing and shedding grit even when soaked.

Each sheet of this Mirka coarse wet/dry sandpaper measures 9" × 11", a size that can be tacked to a sanding block or cut down to fit a handheld pad.
