Microstar® P1500
6": FM-622-1500
6": MID65020CAUS
916GV48 Backup Pad
1066F Interface Pad
Sand using an electric DEROS sander or pneumatic PROS sander with Microstar® 1500 grit (dry) using moderate speed, and an interface pad. The topcoat should "powder" when sanding. Sanding too early risks producing "pills" which will damage the surface.
Abralon® P3000
6": 8A-241-3000
6": MID65020CAUS Sander
916GV48 Backup Pad
Refine sand scratches using 3000 grit Abralon with a 50% overlap pattern (wet).
Spray the pad and surface with clean water. If too much is used, it will be evident by water “slinging” from the pad, and the abrasive will float over the surface with reduced cutting action
