My interior doors don't match the updates we've done on our house. They're brown, hollow core interior doors. I'm either gonna paint them and get new knobs, or just replace them. I hear that you have to spray interior doors and that seems like a pain in the ass. I also hear that buying replacement hollow core doors can also be a pain, getting them to match the door frame and strike plate. I didn't think this was gonna be that big of a deal. Which is easier?
