What is the basic Grind & Seal process?
- Remove existing coatings (for thick coatings, use a 16- or 20-grit diamond abrasive or more aggressive tool specifically for coating removal).
- Grind with a 30- or 40-grit metal-bonded diamond.
- Grind with an 70 or 80-grit metal-bonded diamond.
- Grind with a 120 or 150-grit metal-bonded diamond (or finer, if desired).
- Finish with 2 coats of polyurethane sealer.
