3M 7100098267 Sanding Sheet 400 Grit 2-3/4 in X 45 Yd

Product Description

The 3M 7100098267 is an adhesive-back sanding sheet designed for precision surface finishing in trade and industrial applications. Built with a ceramic aluminum oxide abrasive, this roll delivers consistent 400-grit cut on finishing passes where controlled material removal and a smooth surface profile are required. The C-weight paper backing provides a balance of flexibility and durability, making it well-suited for contoured or flat surfaces. At 2.75 inches wide and 45 yards long, the roll offers extended use before replacement, reducing downtime on production or service work. Installers, fabricators, and finishing technicians are the primary users of this product.

This sanding sheet is used in applications requiring fine finishing on metal, wood, composites, or painted surfaces. The adhesive back allows it to mount directly to compatible backing pads or blocks without additional fastening hardware. The 400-grit rating makes it appropriate for final prep stages, paint scuff sanding, seam blending, and surface conditioning work. It is commonly used in fabrication shops, automotive finishing environments, and general trade finishing tasks where consistent scratch pattern and surface uniformity are critical.

Installation Notes

Apply to a clean, dry backing pad or sanding block, pressing firmly from the center outward to eliminate air pockets. Ensure the mounting surface is free of debris or old adhesive residue before applying a new sheet. When cutting the roll to length, use a straight edge and sharp blade to maintain clean edges. Follow applicable facility safety guidelines for abrasive tool use, including eye protection and dust collection where required.
