Answer
Switch to a coarser grit for removal. Use 60 or 80 for heavy paint removal, 120 for controlled removal, then refine with 150, 180, and 220.
Why it happens
Paint removal is slow when the grit is too fine, the sheet is clogged, or the paint softens and loads the abrasive.
Recommended grit
Use 60 or 80 for heavy removal, 120 for controlled removal, then refine with 150, 180, and 220.
Wet or dry
Use dry sanding for most paint removal. Wet sanding can help with fine residue only when the coating and surface can safely be rinsed.
Success check
Paint is removed at a steady rate and the remaining scratch pattern is ready for medium grit refinement.
What to do
- Check whether the sheet is still cutting or already loaded.
- Use 60 grit only for heavy removal where deep scratches are acceptable.
- Use 80 or 120 for most paint removal.
- Clear dust often so the sheet keeps cutting.
- Replace the sheet when paint loads the abrasive.
- Move to 150, 180, and 220 after the paint is removed.
- Clean the surface before finer prep.
Avoid: Do not use fine finishing grit to strip paint. It will load quickly and waste time.
