Sanding Between Coats

wood finishing

Professional Wood Finisher

When applying several coats of finish to a project it becomes necessary to sand between coats to not only remove any trash that has settled into the finish but also to promote good adhesion between the layers of finish.

Here are some tips:

  1. Never sand any finish with less than 320 sandpaper. Courser grits will scratch the surface too deeply to allow successive coats to fill in the scratches.
  2. Oil and water based finishes require a very thorough sanding for good adhesion.
  3. Lacquer and shellac finishes are reversible finishes so it is more important to sand out the "trash" in the finish than a very complete sanding.
  4. Always sand with the grain when hand sanding.
  5. Random orbital sanders can be used in any direction.
  6. When sanding before the final coat, switch to 800 grit paper.
  7. Remove all dust before proceeding to the next step.
