5" & 6" Solid H&L Black SC Waterproof Discs

These premium Black Silicon Carbide (SC) Waterproof Hook & Loop discs are designed for wet or dry sanding applications where a smooth, fine finish is required.

Silicon Carbide grain cuts fast and leaves a finer scratch pattern than standard Aluminum Oxide abrasives, making these discs ideal for finish sanding and polishing preparation.

Common applications include:

• Automotive paint and clear coat sanding
• Wet sanding primers, topcoats, and lacquers
• Marine and fiberglass sanding
• Composite materials
• Glass and stone finishing
• Fine woodworking applications
• Metal finishing and polishing preparation
• Removing orange peel, dust nibs, and paint imperfections

The waterproof backing allows use with water to reduce loading, improve finish quality, and extend disc life. Hook & Loop backing provides quick disc changes and secure attachment to orbital sanders.

Excellent for fine finishing work where a smooth surface is critical.

John ★★★★★

I've been using these for wet sanding my car's clear coat, and the hook & loop backing holds tight even when soaked. The 6-inch size is great for covering larger panels quickly.

Sofia N. ★★★★★

Finally found discs that don't fall apart after one wet sanding pass—the hook and loop backing held firm through an entire door panel. Gives an even, scratch-free finish on clear coat without loading up too fast.

Abigail D. ★★★★★

Used these wet on a boat hull I’m restoring, and the hook & loop backing held firm even after hours of dunking. The silicon carbide grit cuts smoothly without loading up, and the 6” size covered ground fast. Finished with a mirror shine that surprised me.
