At it again I see! I did our front lounge and the office/kids rooms with floorboards. Cut the edges in with a little rolling edges thing was way easier than tape and brush. I rolled the walls with a long extension on the roller and a halogen light pointing on the wall with 2 pedestal fans running in the room. Was way easier to see from standing back with the long extension pole and light in the room, was colder weather like now so fans and airflow helped the paint dry alot. Stained the timber skirtings in Japan black and cut the shape for a butt up not mitres with a coping saw. Re-done the ceiling first when the floor was concrete with drop sheets. Used the ceiling paint that goes on pink and dries white. Way easier too see. Not a doubt in my mind you've done a trick job!! Animal:-)
