3M 7010383681 Wetordry Sandpaper 400 Grit 9x11 in

Product Description

The 3M 7010383681 is a super fine 400-grit wet-or-dry sandpaper sheet designed for finish sanding between coats of paint, varnish, and other surface treatments. Measuring 9 inches x 11 inches, each sheet can be used dry or with water to minimize clogging and extend the working life of the abrasive. The silicon carbide construction cuts consistently at fine grits, making it a reliable choice for surface prep work on metal, wood, and painted surfaces. Trades professionals and finishing technicians reach for this sheet when a smooth, uniform surface is needed before a final topcoat or primer application.

This sandpaper is suited for light-duty surface preparation tasks in both shop and field settings. Typical applications include sanding between finish coats on furniture, cabinetry, and millwork, as well as scuffing metal surfaces prior to repainting or priming. The wet sanding capability makes it particularly useful when working with automotive finishes, marine coatings, or any topcoat where dust contamination must be minimized. Sold in packs with a minimum order quantity of 10 sheets.
