3M Company 99422NA 220 Grit Sandpaper 9x11 in 25 Count

Product Description

The 3M COMPANY 99422NA is a silicon carbide wet or dry sanding sheet designed for finish sanding work on paint, varnish, and similar coated surfaces. Each sheet measures 9 inches by 11 inches and carries a 220 grit rating, making it well suited for fine material removal and surface prep before topcoating. The flexible A-weight paper backing conforms to contoured surfaces, which reduces the need for excessive hand pressure on curved or irregular workpieces. Each package contains 25 sheets. This product is used by painters, finish carpenters, auto body technicians, and skilled tradespeople who require consistent, fine-grit abrasive performance in both wet and dry sanding applications.

The 99422NA is appropriate for residential and light commercial finishing work where a controlled, fine-grit cut is needed. Typical use cases include scuff-sanding between paint coats, smoothing varnished millwork, and prep work on body filler or primer surfaces. The silicon carbide abrasive delivers a sharper, more consistent cut than aluminum oxide on hard, brittle coatings. Wet use extends sheet life and reduces airborne dust during sanding operations.

Installation Notes

Sanding sheets are installed by hand or wrapped around a sanding block for flat surfaces. When used wet, dampen the sheet and the workpiece surface before beginning to extend abrasive life and control dust. Always wear appropriate respiratory protection when dry sanding coated surfaces, in accordance with applicable safety regulations. Dispose of used abrasive sheets per local waste guidelines, particularly when sanding lead-based paint or other regulated coatings.
