Sia PSA Backup Pad 6 in. No-Hole Firm Low Profile 3/8 in.

Description

Sia PSA backup pad stock gives finishers a firm, low-profile holder for 6 in. pressure-sensitive adhesive sanding discs. This no-hole pad is built for flat-surface sanding where the disc needs a stable backing face, consistent contact, and quick disc changes without a hook-and-loop interface.

Use this pad when a 6 in. PSA disc is the abrasive of choice for sanding wood, composite, metal, solid surface, or coating work. The 3/8 in. firm, low-profile build keeps the disc close to the tool, which helps the operator read the surface and maintain pressure across flatter parts. Because this is a no-hole pad, it is best matched to non-vacuum sanding setups or jobs where dust extraction through the pad is not part of the system.

Sia PSA backup pad applications

• Holding 6 in. PSA sanding discs on compatible sanders
• Flat-panel sanding where firm support matters
• Surface prep before coating, bonding, or finishing
• General shop sanding on wood, metal, composites, and solid surface
• Replacement pad use when an older disc holder has lost grip or shape

Sia PSA backup pad selection notes

PSA pads are chosen when the abrasive disc uses a pressure-sensitive adhesive back rather than siafast hook-and-loop. That makes the pad face and disc adhesive important to the system. A clean pad surface helps the disc stay seated, while the firm backing helps reduce rounding on flat parts compared with softer pads. For hook-and-loop discs, use a siafast pad instead of a PSA holder.
