Answer

Between lacquer coats, scuff lightly with 400 or 600 after the coat dries.

Why it happens
Between-coat sanding should scuff and level small defects without cutting through the finish.
Recommended grit
Use 400 or 600 lightly between cured lacquer coats.
Wet or dry
Dry unless the lacquer system allows wet sanding.
Success check
The coat is smooth, dull, and ready for the next coat.

What to do

  1. Let the lacquer coat dry as directed.
  2. Scuff lightly with 400 or 600.
  3. Remove all dust.
  4. Apply the next coat on a clean surface.
Avoid: Do not sand uncured lacquer that still gums up.
