Napoleon Waterproof Abrasive Sheets (commonly referred to as Water Paper or Wet & Dry Sandpaper) are industrial-grade coated abrasive papers designed for high-precision wet sanding, metal finishing, and paint preparation. Manufactured using premium silicon carbide (SiC) grain electro-coated onto a flexible, resin-bonded latex paper backing, these sheets deliver exceptional sharpness, consistent scratch patterns, and fast stock removal across a wide grit spectrum from P80 up to P2500. The specialized waterproof paper backing resists tearing, cracking, and curling even during prolonged immersion in water, cutting fluids, or solvents, ensuring optimal flexibility around contoured metal surfaces and tight radii. The full resin-over-resin bonding structure prevents premature grain loss, while water lubrication continuously flushes away sanding swarf to eliminate loading and heat generation on sensitive workpieces. Standardized in 230 mm x 280 mm (9 x 11 inch) sheets, Napoleon water papers are widely utilized in automotive refinishing, metal fabrication, tool making, and general industrial maintenance for tasks ranging from coarse filler shaping to micro-fine paint blending and final mirror polishing. Combining high durability, superior wet-use flexibility, and cost-effective performance, they are a staple supply for commercial fabrication and finishing operations.
