Precision Contour Sanding
Even pressure where a rigid pad fails
On curved panels, wheel arches, and complex body lines, a rigid backing pad lifts off the surface and concentrates pressure at the edges. This interface pad adds a compliant foam layer that conforms to the contour, distributing the cut evenly so you don't end up with dig marks or uneven scratch patterns.
Why Interface Matters
Less rework, better results
One small pad, a big difference on complex surfaces.
-
Contour Compliance
Foam cushion conforms to curves so the abrasive cuts evenly across the whole surface.
-
Full Dust Extraction
44-hole pattern aligns with Mirka discs to keep extraction uninterrupted.
-
Durable Bonding
Special resin construction resists delamination under repeated sanding heat and pressure.
-
Universal Fit
Velcro on both faces fits any 77mm or 125mm Mirka-style backing pad instantly.
Interface Pad vs. Direct Sanding
What you give up without an interface layer
Sanding directly on a rigid backing pad is fine on flat panels. On anything curved, the difference in outcome is hard to ignore once you've used an interface pad.
| Feature | DetailerSA | Alternative |
|---|---|---|
| Even pressure on curved surfaces | Yes | No |
| Compatible with standard Velcro backing pads | Yes | Yes |
| Dust extraction maintained | Yes | Yes |
| Reduces edge dig-in and pressure spikes | Yes | No |

Built for Extraction
44 holes that keep dust moving
The 44-hole grip pattern is engineered to line up with Mirka abrasive discs and your sander's dust port, so adding the interface layer doesn't choke your extraction. Clean dust flow means a clearer view of the surface, cooler sanding temperatures, and longer abrasive life.

Questions
Frequently asked
What is an interface pad and why do I need one?
An interface pad is a foam layer that goes between your backing pad and your sanding disc. On flat panels a rigid backing pad works fine, but on curved or contoured surfaces it rocks and creates uneven pressure. The interface pad adds compliance so the abrasive follows the surface instead of bridging across it, giving you a more even scratch pattern and less risk of burning through edges.
Which backing pads is this compatible with?
This interface pad is designed for 77mm and 125mm Velcro-style backing pads, including Mirka backing pads. Both the top and bottom faces use Velcro attachment, so it sandwiches securely between the backing pad and the abrasive disc.
Which abrasive discs work with this pad?
It is specifically designed to pair with Mirka grip (Velcro-backed) sanding abrasives. The 44-hole pattern is engineered to align with Mirka's dust extraction hole layouts, maintaining maximum suction through to your random orbital or gear-driven sander.
What surfaces can I use this on?
The pad is suited to automotive paint refinishing, glass scratch removal, metal processing, wood processing, composites, marine gel-coat, and construction and decoration applications. Essentially any surface where a curved or contoured area needs sanding with a softer, more controlled contact.
Does the interface pad affect dust extraction?
No. The 44-hole pattern is aligned to pass dust and debris straight through to your sander's extraction system, so you don't sacrifice dust management by adding the interface layer. Keep the holes on the abrasive disc aligned with the holes on the interface pad for best results.
Will this work with my random orbital sander?
Yes, provided your sander uses a 77mm or 125mm Velcro backing pad. The interface pad simply clips between the existing backing pad and your abrasive disc - no machine modification needed. It works with both random orbital and gear-driven sanders in those sizes.
How does the special resin bonding help?
The special resin bonding holds the foam structure together under the heat and friction of repeated sanding passes. It resists delamination and deformation better than standard adhesive bonding, so the pad maintains its cushioning properties across multiple uses rather than compressing out flat quickly.
How do I care for and store the interface pad?
After use, brush or blow off any abrasive dust and check the Velcro faces for loading. If the hooks are clogged with foam or dust, a stiff bristle brush cleans them up. Store the pad flat, away from direct sunlight and solvents, to keep the foam from compressing or degrading between uses.
