When you have to paint around trim on interior doors, and especially in
tight corners where the wall is all but hidden behind the trim - do you
remove the trim before painting or just get in there and paint around the
trim, maybe tape it off or something if its real tight?


When it is in a corner, protect the wall with a length of aluminum foil
or plastic taped along the edge of the door trim. Smoosh some paint
onto the side of the trim with a small foam roller with the excess paint
squeezed out. Continue on along the face of the trim with brush to
smoothe out the excess.
