A lick of paint added to any surface enhances its aesthetic, but only if the finish is well executed. The key to a perfectly painted wall is preparing it well before you begin applying fresh paint. You can add paint to any surface but if the paint underneath is chipped, peeling or rough it will show through when the new paint has dried.

Whilst this may not be such an issue for the fence outside or areas that aren’t very visible, for highly visible areas like the living room, it’s OK to desire a better finish. Ideally, you’ll have a smooth, clean, matte surface to apply your new paint to.
