Which Sandpaper Grit Should You Use
“Which Sandpaper Grit should I use?” Is one of the most common questions we are asked.
The answer is as simple as 1, 2, 3, because sandpaper is based on the size of grit particles, which are rated numerically. The higher the number the finer the grit, the lower the number the coarser it will be.
Below are some common sandpaper grit sizes and the kinds of projects to use them on:
Common Sandpaper Grit Sizes:
- 40 - 80 Grit Sandpaper: Very coarse grit sandpaper is perfect for rough sanding and removing stock quickly, such as sanding the bottom or top of a sticking door.
- 100 - 150 Grit Sandpaper: Medium grit sandpaper makes a great starting point for most projects, from sanding unfinished wood to removing old varnish.
- 180 - 220 Grit Sandpaper: Finer grit sandpaper is ideal for removing the scratches left by coarser grits on unfinished wood and for lightly sanding between coats of paint.
- 320 - 400 Grit Sandpaper: Very fine grit sandpaper is used for light sanding between coats of finish and to sand metal and other hard surfaces.
