4. Operating Instructions
Follow these guidelines for effective sanding with the 3M Wetordry Abrasive Sheet.
4.1 Dry Sanding
- Attach the abrasive sheet to your sanding block or tool.
- Apply even pressure and sand in a consistent pattern.
- Regularly clear dust from the sanding surface and the sheet to maintain cutting efficiency.
4.2 Wet Sanding
- Soak the abrasive sheet in water for a few minutes before use to enhance flexibility and performance.

5. Maintenance and Storage
Proper maintenance and storage will extend the life of your abrasive sheets.
- After wet sanding, rinse the sheets thoroughly with clean water and allow them to air dry completely before storing.
- Store unused sheets in their original packaging or a dry, cool place away from direct sunlight and humidity to prevent degradation.
- Avoid creasing or folding sheets sharply, as this can damage the abrasive surface.
6. Troubleshooting
This section addresses common issues encountered during the use of abrasive sheets.
| Problem | Possible Cause | Solution |
