How to Choose the Right Sandpaper Grit and Type
If the sanding sheet is too small, you do not use the full range of the sander and that is, of course, a waste. But a too large sanding sheet does not work well either. The sandpaper is not tight against the sanding sole, so you will not get a nice result.
Sometimes coarse papers are required but it is knowing when to use them. This also applies to fine abrasive papers as these can clog very quickly.
The particles (also known as grains or grit) are sifted through screens and sorted by size before being bonded with adhesive to a paper, sponge, or cloth-type backing to create an abrasive material that’s handy in a number of do-it-yourself situations. Grit is a measurement of the size of the abrasive grains on a piece of sandpaper; higher grit numbers denote smaller, more densely-spaced grains. Unless you’re doing precision wood crafts, you would normally use 220-grit paper only for sanding finish. It’s too fine to make much of a difference on bare wood. Instead of one hand sanding, if you want to go for both hand sanding, emery made sandpapers can be trusted.
