Mirka Galaxy Ceramic 5 inch Multi-Fit Grip Hook and Loop Sanding Discs

Use these if: You're prepping a fiberglass, wood, or composite hull surface before priming or topcoating. These discs are the first step in a professional marine paint system.

Mirka Galaxy 5-inch Ceramic Hook & Loop Sanding Discs deliver fast, consistent material removal with self-sharpening ceramic grains that stay sharp longer than standard abrasives — so you get more life per disc and a smoother surface ready for primer.

• Available in grits 40–2000 (rough stock removal to fine finishing)
• Multi-hole dust extraction keeps your workspace clean and visibility high
• Compatible with all standard 5-inch hook & loop sanders
• Works on fiberglass, gelcoat, wood, metal, and composites

Complete your system: After sanding, apply Quantum 45 Epoxy Primer for adhesion and corrosion protection, then finish with Quantum99 Topcoat for a high-gloss, durable marine finish.
