  • Inspect the trim – Before you start painting the trim, make sure it has no holes or cracks. These can ruin the outcome if you do not fill them with putty. Sand down all rough areas with fine sandpaper.

  • Take the other clean bucket and wash your paint sprayer for interior trim. The Sprayer Operation Manual will explain how to clean the equipment.

  • Keep the spray gun about 8 to 12 inches away from the surface. Also, keep your wrist still as you work the trim.
