3M 7000045203 Sanding Sheet 120 Grit 3-1/4 X 70 in

Product Description

The 3M 7000045203 is an adhesive-back sanding sheet designed for surface preparation and finishing work in trade and industrial environments. It uses a silicon carbide abrasive at 120 grit, placing it in the fine grade range — suitable for smoothing surfaces, light stock removal, and prep work before finishing coats. The sheet measures 3-1/4 inches wide by 70 inches long, with an A-weight refill pad roll backing that provides flexibility and consistent abrasive contact across the work surface. It is installed by cutting or fitting to the applicable sanding tool or pad system.

This sanding sheet is used in applications where a conformable, adhesive-mount abrasive is required. The refill pad roll format makes it appropriate for use on flat or mildly contoured surfaces in woodworking, metal finishing, drywall work, and surface coating preparation. The 120 grit rating suits finish sanding stages where coarser scratches from prior grits need to be refined. Tradespeople in flooring, cabinetry, auto body prep, and general fabrication commonly use this format.

Key Features

• Silicon carbide abrasive for consistent cut on wood, metal, and composite surfaces
• 120 grit fine grade for finish-stage surface preparation
• A-weight refill pad roll backing provides flexibility and surface conformability
• Adhesive back mounting — no clamps or fasteners required
• Sheet dimensions of 3-1/4 inches wide by 70 inches long allow for multiple cuts per sheet

Compatibility

Designed as an adhesive-back refill pad roll sanding sheet for use with compatible pad systems that accept a 3-1/4 inch wide abrasive sheet in a roll or cut-to-length format.

Installation Notes

Installation is performed by cutting the sheet to the required length and pressing the adhesive side firmly onto a clean, dry backing pad. Ensure the mounting surface is free of dust and debris before application to achieve full adhesive contact. Wear appropriate eye protection and a dust mask or respirator when sanding, in accordance with applicable safety standards. Replace the sheet when abrasive performance drops or the sheet shows visible wear or loading.
