How to Sand Leather Smooth. Leather can be sanded utilizing a leather sanding machine. These can be benchmounted belt sanders, portable sanding machines, or bench grinders. It is important to consider the fineness of the grit of the sandpaper, and work from larger grits to smaller, more finer grits.

observed: The sand should be nearly white in color; it should be of medium fineness (passing a 20 to 50 mesh horizontal sieve); the grains should be uniform in size, even, and angular, or, less preferably, they may be rounded. A simple chemical test may be employed by heating the sand in a dilute acid.
