3M 7100140811 Aluminum Oxide Sandpaper 9x11 Fine Grit

Product Description

The 3M 7100140811 is an aluminum oxide sandpaper sheet designed for general-purpose sanding of paint, wood, and metal surfaces. Measuring 9 inches by 11 inches, this fine-grit sheet delivers consistent abrasive performance across a range of surface prep tasks. Aluminum oxide is a durable abrasive mineral that cuts efficiently and holds up through extended use, making it a reliable choice for both production sanding and finish work. Trade professionals and experienced DIYers use these sheets for smoothing surfaces between coats, removing light material, and preparing substrates for finishing. Each pack ships with a minimum quantity of 10 sheets.

These sandpaper sheets are suited for residential and light commercial applications where surface preparation is required before painting, staining, coating, or finishing. Common use scenarios include prepping trim, cabinetry, metal fixtures, and previously painted surfaces. The 9 x 11 inch sheet size fits standard sanding blocks and hand-sanding applications, and can be cut or folded to fit specific tasks. Electricians, finish carpenters, painters, and general maintenance technicians commonly keep these sheets on hand for surface prep work in the field.
