Tips for Finishing Trim Molding

Finishing trim molding, such as door facings and crown molding, is often easier to do before it’s installed.

  1. Lay the molding to be finished on sawhorses to prevent drips and runs.
  2. Rather than finishing with a standard bristle brush, try using a small foam roller. Not only does the finish go on faster, but there are no annoying bristles to come off in the work.
  3. Once the finish has been applied, go over it with a foam brush to smooth the finish and remove any bubbles.


  1. We have installed molding around openings that are rounded at the top and straight down the sides. In the places where the two moldings meet, it is rough looking. We have sanded with sand paper; however, it is not smooth. What do you recommend?
    Many thanks,
