3M 7100140808 Aluminum Oxide Sandpaper 9x11 Coarse

Product Description

The 3M 7100140808 is a coarse-grit aluminum oxide sandpaper sheet designed for aggressive material removal across a wide range of surfaces. Measuring 9 inches by 11 inches, each sheet delivers the durability and cutting action that trade professionals expect from aluminum oxide abrasive media. The coarse grit rating makes it well suited for fast stock removal, stripping old finishes, and leveling uneven surfaces before progressing to finer grits. Licensed trades and experienced DIYers reach for this sheet when the job calls for serious abrasion rather than finish work. Sold in packs, it is a practical choice for high-volume sanding tasks on job sites or in the shop.

This sandpaper sheet is used across multiple trades and applications. It is appropriate for sanding bare wood, painted surfaces, metal, plastic, drywall, and fiberglass. Contractors, carpenters, painters, and remodelers commonly use coarse-grit aluminum oxide sheets during prep work — flattening rough lumber, removing rust or scale from metal, knocking down joint compound on drywall, or scuffing fiberglass panels before bonding. The 9-inch by 11-inch sheet size fits most standard hand-sanding blocks and can be cut down for detail work as needed.

Compatibility

Installation Notes

No power connection or mechanical installation is required for hand-sanding sheets. Secure the sheet firmly to a sanding block before use to maintain even pressure and reduce hand fatigue. When sanding drywall or dusty surfaces, wear appropriate respiratory protection and eye protection per OSHA guidelines. Dispose of worn sheets that have lost cutting action rather than continuing to apply excess pressure, which can cause uneven surfaces.
