Five new interior wooden doors were hung in older apartment. Although they came with what I think is a white primer, they need to be painted. I would like to tap the experience of the community so as to understand best practices
- The door is already hung, is there a compelling reason to take it down to paint?
- The door is new with primer: does it need any prep before painting?
- Is there any reason not to use a roller to expedite the process?
- Are some classes of paints preferable over others?
Any lessons-learned or pitfalls to avoid is appreciated: especially if you have done this a dozen times or more.
