Plain interior doors do not increase the visual appeal inside a home. If your home has plain, boring, and dull interior doors, it's time to spruce them up a bit. You do not need to completely remodel an interior door to create a new look. A fresh coat of paint and replacing the existing doorknob with an updated, newer one spruces up the door. Depending upon how many interior doors need sprucing up, allow a weekend to complete this project. Allowing a weekend ensures ample time for the paint to dry.
Lay newspaper or a tarp on the flooring underneath the interior door to protect against paint spillage. Place the interior paint, paint tray, paint roller and paintbrush on the tarp.
Open the paint can with a screwdriver. Place the screwdriver under the lip of the paint can lid and gently pry open. Stir the paint with a paint stir stick until it is completely mixed.
Pour paint into the paint tray. Roll the paint roller back and forth. Be sure to coat the entire roller.
Apply paint to the interior door with the paint roller. Use an up-and-down motion until the entire door has a fresh coat of paint.
Apply paint to the parts of the interior door the paint roller could not reach with your paintbrush. Dip the paintbrush in the paint tray to apply paint and paint the door in the same up-and-down motion.
Repeat all steps for the opposite side of the interior door.
Remove the metal strike plate on the interior door with a screwdriver. The metal strike plate is attached to both sides of the door with screws.
Place your hands on both side of the doorknob and pull the doorknob from the door. You will have both sides of the doorknob in your hands when it's removed.
Replace the long bolt in the door holding the doorknob in place, if different from the one that came with the new doorknob. Pull out the old bolt and gently replace it with the new one. If the bolts match, you can skip this step.
Grasp the new doorknob in one hand, and place one side of the doorknob against the door in its designated area. Hold the opposite side of the doorknob against the door at the same time.
Align the new doorknob to the long bolt inside the door. If they do not line up immediately, realign until both sides of the doorknob align perfectly to the bolt.
