After extensive plaster ceiling repairs, where my ceiling meets the walls, there is a transition between plaster (ceilings) and drywall (walls) about one foot down on the walls. After painting with flat latex paint, the painted plaster on the upper walls appears lighter and shinier than the painted drywall (lower down on the walls). This is especially so right where the wall meets the ceiling, where I've used a brush (rather than a roller) to cut-in. (Of course, the plaster is much smoother than the drywall.)
Is there anything I could do to minimize the transition between the plaster and the drywall in terms of painted finish/texture? Someone suggested using a thicker nap roller on the plaster to create some texture that would match the "orange peel" appearance of the drywall.
Any advice?
