Answer

Use 320, 400, or 600 between coats. Sand lightly and remove all dust before the next coat.

Why it happens
Between-coat sanding should smooth small defects without cutting through the coating.
Recommended grit
Use 320, 400, or 600 between coats, following the coating instructions.
Wet or dry
Dry or wet only where the coating instructions allow.
Success check
The surface feels smooth and the previous coat is not cut through.

What to do

  1. Let the coat cure as directed.
  2. Sand lightly with 320, 400, or 600.
  3. Remove dust completely.
  4. Apply the next coat only when the surface is clean.
Avoid: Do not sand uncured paint.
