Mirka 6-in PSA Backup Pad

Dependable Support for PSA Sanding Discs:

The Mirka 6" PSA Backup Pad provides a secure and supportive mounting surface for compatible pressure-sensitive adhesive sanding discs. Its adhesive-compatible face holds PSA abrasives firmly in position during sanding while allowing the disc to be removed and replaced when needed.

The pad’s medium firmness provides a practical balance of support and cushioning for smooth, controlled sanding. It helps maintain consistent abrasive contact with the work surface, supporting dependable performance and a more uniform sanding result.

Restore Your Sander’s Performance:

Backing pads naturally wear with continued use and may eventually lose their shape or ability to hold abrasives properly. A worn pad can reduce surface contact and contribute to inconsistent sanding results. Replacing it helps restore reliable abrasive attachment and effective sanding performance.

This 6-inch backing pad uses a standard 5/16"-24 threaded attachment for connection to a compatible sanding or polishing tool.
