Pro Tip: Always connect your sanding block to an efficient dust extraction system. It extends the life of abrasives and ensures smoother finishes.
Recommended Base Settings (Guideline Values)
- Surface prep: Grit P120 – P240
- Intermediate sanding: Grit P320 – P400
- Fine sanding (for coatings): Grit P600 – P800
- Apply light pressure – let the foam do the work
- Use active dust extraction with the 32-hole system
Professional Workflow (6 Steps)
- Connect the block to the extraction hose (Ø 20 mm fitting).
- Attach the matching Grip 32L abrasive sheet and press evenly.
- Sand with light, overlapping strokes using consistent pressure.
- Blow off the surface and check the abrasive regularly.
- For fine coatings, increase grit and reduce pressure.
- After use, store the block flat and clean of dust.
Troubleshooting
| Issue | Cause | Solution |
|---|---|---|
| Uneven sanding pattern | Too much pressure | Use light pressure and consistent strokes |
| Abrasive detaches | Dust between block and pad | Clean the grip surface and reattach |
| Excessive dust | Weak extraction flow | Check hose and increase airflow |
| Scratches after sanding | Grit too coarse | Switch to finer grit > P400 |
Maintenance & Care
- Blow off or vacuum the block after every use
