Sia 5999.0515 Interface Pad, 5 Inch x 1/2 Inch Soft Micro Hook

Description

Sia 5999.0515 Interface Pad is a Sia interface pad for adding cushioning between a 5 inch Siafast abrasive disc and the backup pad. The cataloged format is a 5 inch, 1/2 inch soft micro hook pad for contour sanding, edge blending, and finish work where a rigid pad would feel too direct.

Sia interface pad Benefits

• Soft 1/2 inch pad layer helps the sanding disc follow gentle curves and rounded edges.
• Micro hook face supports Siafast hook and loop abrasive discs in compatible sanding setups.
• Interface layer can reduce hard pad marks when finishing solid surface, wood, paint, or composite parts.
• Disposable accessory format is easy to replace when the hook face loads, tears, or loses grip.
• Useful for shops that keep several pad densities ready for flat sanding and shaped surfaces.

Use this pad when the workpiece has profiles, eased edges, or broad curves that need more compliance than a standard backup pad alone. It can help keep the abrasive in contact with the surface while reducing the chance of cutting too aggressively at high spots.

Common Applications for Sia interface pad

• Contour sanding on solid surface counters and edge details.
• Finish sanding on wood, primer, paint, and composite parts.
• Blending transitions where a hard backup pad may leave edge marks.
• Intermediate sanding steps between coarse shaping and final surface prep.

Compatible Abrasive Setup

• 5 inch Siafast hook and loop abrasive discs.
• Compatible backup pads used with random orbital sanders.
• Fine finishing steps where pad softness and operator control matter.
• Bench or field sanding kits that separate backup pads from replaceable interface pads.
