3M Company 9085NA 400 Grit Wet Dry Sandpaper 5 Pack

Product Description

The 3M COMPANY 9085NA is a waterproof silicon carbide sandpaper sheet designed for wet or dry sanding applications. Each sheet measures 9 inches x 11 inches and is cut to a 400 grit rating, making it well suited for fine finishing work between coats of varnish, paint, and other surface finishes. This pack contains 5 sheets. The silicon carbide mineral is a sharp, synthetic abrasive that cuts quickly and leaves a smooth surface. Using the sheets wet reduces clogging and extends abrasive life, which is a key advantage in finish-coat work where surface contamination needs to be minimized.

This sandpaper is appropriate for use in woodworking, automotive finishing, and general surface preparation tasks where a fine, consistent scratch pattern is required between finish coats. The 400 grit rating targets light material removal and surface smoothing rather than aggressive stock removal. Tradespeople and skilled DIYers working on furniture refinishing, cabinetry, or painted surfaces will find the wet sanding capability particularly useful for achieving a flat, uniform surface before the next coat is applied.
