Hardness
Shore 00: 65 ±10
Recommended Storage Temp
≈ 20 °C
Tip: Always keep the block flat for consistent sanding results. Excessive point pressure can cause ripples. Use dust extraction to extend abrasive life.
Recommended Basic Settings (Reference Values)
- Working pressure: even, below 2 kg hand force
- Abrasive size: depending on model, 70×198 mm or 70×400 mm
- Dust extraction: via rotating joint (Ø 20 mm)
- Ambient temperature: around 20 °C, avoid direct sunlight
Pro Workflow: 6 Steps for a Perfect Finish
- Select the right block type (flexible or rigid) for your surface.
- Attach a compatible abrasive (e.g. Mirka Abranet) to the hook surface.
- Connect optional dust extraction to the nylon joint.
- Move the block in long, even strokes across the surface.
- Clean the block regularly with compressed air or a damp cloth.
- Store flat to prevent deformation.
Troubleshooting
- Uneven sanding patterns: Keep pressure even and surface contact flat.
- Clogged abrasives: Check suction and clean with compressed air.
- Grip surface worn: Clean or replace the hook face.
- Overheating: Reduce hand pressure and allow cooling pauses.
Maintenance
- Clean hook surface regularly
- Keep rubber grip dry
- Store flat and cool
- Avoid direct heat exposure
- Check foam integrity periodically
FAQ
- Can I clean the block with water? – Yes, slightly damp only; avoid solvents.
- Are all abrasive rolls compatible? – Only hook-and-loop systems (e.g. Abranet).
- How do I detect wear? – Reduced grip or uneven pressure indicates replacement.
- Which grits are suitable? – From P80 to P800 depending on the surface.
- Can I use it without dust extraction? – Yes, but extraction improves tool life and cleanliness.
Conclusion: Mirka Hand Blocks deliver precise, uniform sanding results with ergonomic design and long-lasting materials. The flexible 70×400 mm Yellow Grip 53L model stands out for professional surface finishing and repair work.
