3M 7100149989 Pro Grade Sandpaper 180 Grit 9x11

Product Description

The 3M 7100149989 is a 180-grit advanced sandpaper sheet designed for professional surface preparation and finishing work. Measuring 9x11 inches, each sheet features a no-slip grip backing applied to the reverse side, which mechanically locks the sheet against the sanding block or hand grip during use. This backing is engineered to extend sheet life significantly compared to conventional sandpaper, reducing how often sheets need to be swapped out mid-job. The 180-grit abrasive is suited for fine sanding passes on wood, painted surfaces, and light material removal where a smooth finish is the target. Packaged in a multi-sheet pack, this product is stocked for repetitive use by finish carpenters, painters, and general trades.

This sandpaper is appropriate for residential and light commercial finishing applications including furniture refinishing, door and trim prep, drywall feathering, and between-coat sanding on painted or stained surfaces. The 9x11-inch sheet size is compatible with standard hand sanding blocks and can be folded or cut for detail work. The 180-grit rating places it in the fine-sanding range, making it most effective after coarser grits have addressed stock removal and the surface is being brought to final smoothness before topcoat application.

Installation Notes

No tools or fasteners are required for use. When cutting or folding sheets to size, use a straightedge to avoid tearing the abrasive surface unevenly. Avoid using these sheets on power orbital or belt sanders unless the product is specifically rated for machine use. Inspect sheets regularly during use and replace when abrasive loading or backing wear reduces cutting effectiveness.
