Product Details

3M Wetordry Paper Sheet 431Q delivers consistent, professional-grade abrasive performance for both wet and dry sanding applications. Designed for fine finishing work across automotive, marine, and woodworking industries, these 9 in x 11 in sheets use a sharp silicon carbide mineral bonded to a flexible C-weight paper backing for smooth, controlled material removal.

The 431Q series features 3M's precision electrocoated abrasive construction, which distributes cutting particles uniformly across the sheet surface for a consistent scratch pattern and extended sheet life. The waterproof resin bond allows wet sanding, which helps flush away swarf, reduce loading, and keep the surface cool — making these sheets ideal for paint prep, primer leveling, clear coat finishing, and lacquer sanding.

Key Features:

  • Abrasive Mineral: Silicon carbide — fast cutting, ideal for hard surfaces and fine finishing
  • Grit: 100 — medium cut for material removal and surface prep
  • Sheet Size: 9 in x 11 in — standard full-sheet size, easily cut to fit sanding blocks
  • Backing: C-weight paper — flexible enough for contoured surfaces while maintaining control
  • Bond Type: Waterproof resin bond — suitable for wet or dry sanding
  • Grade Series: 431Q — premium electrocoated construction for uniform grit distribution
  • Pack Quantity: 50 sheets per inner pack; 250 sheets per case

These sheets are well-suited for sanding between coats of paint or varnish, surface preparation before priming, and final finishing on metal, fiberglass, and wood substrates. The universal 9x11 format is compatible with most hand-sanding blocks and can be folded or cut to any custom size.

quick and easy

so far so good - first step: order

I mistakingly ordered two of the product. someone from customer service contacted me to verify it I actually wanted two. So we cancelled the extra order. Most companies would not go that step in customer service, much appreciated. The product arrived really fast and was exactly what I ordered and worked perfectly.

Fair price reasonable delivery time

Good price for specialty purchase, and quick turnaround.
