Product Information
Full details
The Mirka Interface Pad (70x198mm) is an essential accessory for professional painters, woodworkers, and automotive technicians who require superior control when hand-sanding curved or contoured surfaces. By adding a 10mm layer of flexible foam between your sanding block and the abrasive, this pad allows for consistent pressure distribution and prevents sand-through on edges; however, it is specifically designed for use with grip-backed abrasives and may not be suitable for extremely flat, high-pressure leveling applications where a rigid backing is required.

FAQs
Can I use this pad for wet sanding?
Yes, the foam material is resilient to moisture, though you should ensure you are using waterproof abrasives.
Does this pad fit all 70x198mm blocks?
It is designed for standard 70x198mm hook-and-loop systems, but performance is best with Mirka-brand vacuum blocks.
Why does the pad have 56 holes?
The high hole count provides maximum surface-area coverage for dust extraction, which keeps your sandpaper cutting effectively for longer.
Is this pad washable?
You can rinse it with mild soap and water if it becomes clogged, but ensure it is completely dry before reattaching.
Will this pad make my sanding block too soft?
It adds 10mm of 'give', which is excellent for contours but should be removed if you need a strictly rigid surface for flat panel leveling.
Troubleshooting
Abrasive sheet is slipping during use
Check that the hook-and-loop material is free of heavy dust buildup; clean with a stiff brush or compressed air.
Pad no longer sticks to the sanding block
Inspect the hooks on your sanding block for wear; if the block's hooks have flattened, the pad will lose adhesion.
Excessive dust accumulation
Ensure the 56 holes are aligned with the holes in your abrasive sheet and the suction channels of your vacuum block.
Pros and Cons
Pros
- Excellent for contour sanding
- Effective dust management via 56-hole pattern
- Reduces swirl marks and burn-through
- Easy to switch out with hook-and-loop system
Cons
- Adds softness which can hinder flat leveling
- Specific to 70x198mm dimensions
- Not intended for non-grip abrasives
Setup, Compatibility & Care
To set up the pad, ensure your sanding block is clean and free of debris. Attach the loop side of the interface pad to the hook face of your sanding block, pressing firmly to ensure an even bond. Then, apply your grip-backed abrasive sheet to the face of the interface pad. Compatibility is universal for any hook-and-loop sanding block measuring 70x198mm. For care, avoid using heavy solvents that could degrade the foam structure. Periodically tap the pad against a hard surface or use an air nozzle to clear dust from the 56-hole extraction channels to maintain optimal performance.
