Mirka WPF PRO Waterproof Sanding Sheets

Mirka WPF PRO Waterproof Sanding Sheets are wet and dry sandpaper sheets for manual wet sanding. They use a waterproof abrasive with a lasting, aggressive cut. The non-absorbent, curl-resistant construction gives smooth, controlled sanding. They suit automotive refinishing, marine, and composite work, and are available in a range of grits.

Key Features:

• Waterproof construction: latex-impregnated C-weight paper backing for wet or dry use
• Silicon carbide abrasive: fast-cutting grain for efficient material removal
• Resin-over-resin bonding: a durable bond that holds up during wet sanding
• Closed coat: a consistent scratch pattern and a quality finish, even on coarser surfaces
• Curl resistant and non-absorbent: stable handling, with minimal suction to the surface for a smooth sanding motion

Typical Applications:

• Primers, paint, and lacquers
• Clear coat sanding and finish leveling
• Plastics, non-ferrous metals, and composite materials
• Body filler, putty, and plaster

For the flattest, most even finish, use the sheets with a foam or dual-density sanding block. The aggressive cut helps repair and finishing jobs go faster, which saves time and abrasive cost.
