Choosing right grit
  • Sanding sponge product is graded based on the number of abrasive material per square inch, so higher numbers reflect a finer grit and lower numbers indicate a coarser grit. It usually goes something like this: medium, 80–120; fine, 150–180; very fine, 220–240; extra fine, 280–320; ultra fine, 400-2000.
  • Sanding with progressively finer grits removes the scratches left by the previous grit and eventually leaves a smooth finish. So start with a coarser grit and move on to a finer grit for your polishing step.
  • Coarse-grit ones will remove material fast and when followed by finer grit ones, make for much easier and quicker sanding. This is opposed to using a finer grit to sand the entire piece. You can do that, but it will take much more time and energy!
