Serious Grit 180 Grit Ceramic Mesh Sanding Discs are built for refined pre-finish sanding across wood, drywall, and painted surfaces. The fine ceramic grain evens out surface inconsistencies without over-cutting, making it perfect for prepping before paint or stain. And with an open mesh construction that allows for full-surface dust extraction, you get a cleaner finish and a cleaner workspace. Our 6" (150mm) discs offer a universal fit for any hook & loop sander—no holes to align or match up. The ceramic abrasive provides consistent cutting and long life, while our reinforced backing solves one of the biggest problems with mesh discs: poor adhesion. These stay locked in place job after job. From furniture builds to finish drywall work, 180 grit is the ideal choice for final smoothing before you move to finish coats.
