3M Company 20120-G-4 Sandpaper 120 Grit 9x11 Inches 4 Pack

Product Description

The 3M COMPANY 20120-G-4 is a 120-grit sandpaper sheet designed for general-purpose sanding across a range of surfaces. Each sheet measures 9 inches by 11 inches and features a no-slip grip backing that keeps the sheet seated during use. The abrasive mineral technology is formulated to extend sheet life significantly compared to standard sandpaper, reducing how often sheets need to be swapped out mid-job. This 4-pack format suits contractors, finish carpenters, painters, and maintenance technicians who need reliable stock on hand for surface prep work.

This sandpaper is suited for residential and light commercial applications including wood surface preparation, paint scuffing, drywall finishing, and general material smoothing. The 120-grit rating positions it in the medium-fine range, making it appropriate for intermediate sanding stages where coarser scratches need to be worked out before final finishing. It can be used by hand or with a sanding block on flat and contoured surfaces.

Key Features

• 120-grit abrasive rated for medium-fine surface preparation
• Sheet dimensions: 9 inches by 11 inches, standard full-sheet size

Compatibility

Installation Notes

Sandpaper sheets are installed by hand or with a sanding block — no power tools or trade licensing required for general use. When used in occupational settings, follow applicable dust control practices and wear appropriate respiratory protection per OSHA guidelines. Secure the sheet firmly against the backing block before applying pressure to prevent slipping and uneven wear.
