Your Guide to Getting the Best Finish with Orbital Sanding Discs

Whether you’re refinishing hardwood floors, prepping a car surface for painting, or smoothing down a piece of furniture, choosing the right sandpaper grit is critical to achieving a high-quality result. At LESNIC, we offer a wide range of orbital sanding discs in various sizes and grit levels — but how do you know which one to use?
Let’s break it down:
🔧 What Is Sandpaper Grit?
Grit refers to the size of the abrasive particles on the sandpaper surface. The lower the number, the coarser the grit; the higher the number, the finer it is.
📊 Sandpaper Grit Levels & Their Uses
| Grit | Type | Typical Use Cases |
|---|---|---|
| 40–60 | Coarse | Rapid removal of material, stripping paint or varnish, leveling rough surfaces |
| 80–120 | Medium | General-purpose sanding, surface prep before painting or staining |
| 150–180 | Fine | Smoothing surfaces, final sanding before finishing |
| 220–400 | Very Fine | Between coats of finish, polishing wood or metal |
| 600–800 | Ultra Fine | High-gloss finishes, automotive detailing, polishing delicate surfaces |

When in doubt, begin with a coarser grit to remove imperfections quickly. Then work your way up to a finer grit to smooth and polish the surface. Always sand with even pressure and let your orbital sander do the work — don’t press too hard.
