Answer
Between cured lacquer coats, sand very lightly with 400 or 600, then remove all dust before recoating.
Why it happens
A cured coat may need very light leveling or scuffing before the next coat, depending on the finish instructions.
Recommended grit
Use 400 or 600 lightly between cured lacquer coats.
Wet or dry
Dry for light scuffing; wet only when the lacquer system allows it.
Success check
Dust nibs are flattened and the coat is clean before the next layer.
What to do
- Let the lacquer coat cure as directed.
- Sand lightly with 400 or 600.
- Avoid cutting through edges.
- Remove dust completely before recoating.
Avoid: Do not sand uncured lacquer.
