I'm new to painting so I need some advice. I found an old door on the curb and rescued it, to use as the human door on my new coop. It has stain on one side, and paint on the other. Both are in really bad shape. With the painted side, I'm guessing I'll have to strip the old paint, then prime and repaint. But what should I do with the stained side? The stain is really soaked into the wood, so it will be hard to get out. Should I just prime+paint on top of the stain? Also, the door has some detail on it, which will make completely stripping the old paint a pain in the butt... How clean do I have to strip it for the new paint to hold? I know the cleaner the better, but... realistically speaking...?
Here's the stained side:
