3M Company 99401NA-CC 220 Grit Aluminum Oxide Sandpaper 25ct

Product Description

The 3M COMPANY 99401NA-CC is a 220-grit aluminum oxide sandpaper sheet designed for dry sanding of painted surfaces, bare wood, and metal. Each sheet measures 9 inches by 11 inches and features a flexible A-weight paper backing that conforms to flat and slightly curved workpieces. The fine 220-grit cut makes this sheet well suited for finish sanding between coats of paint or primer and for smoothing wood prior to final finishing. Sheets are sold in a 25-count box, giving tradespeople and finishing contractors a ready supply for production work or job-site use.

This sandpaper is intended for hand sanding applications on painted surfaces, bare wood, and light metal finishing where a fine scratch pattern is required. The flexible A-weight backing allows the sheet to be folded or wrapped around a sanding block without cracking, which is standard practice for finish-coat preparation on trim, cabinetry, and light metalwork. Packaging is tri-lingual and die-cut for straightforward retail or shop organization. Each box contains 25 individual sheets sized for full-sheet hand sanding or cutting down to fit palm sanders and sanding blocks.

Installation Notes

These sheets are intended for dry sanding only — do not use with water or liquid lubricants. When cutting sheets to size, use a straightedge and score the backing side to get a clean break.
