Another trip to B&Q. As expected the ceiling required a further coat of paint and GF did not quite have enough. Also, he needed some additional paint roller sleeves and another paint tray.
Back home the additional coat was soon applied and immediately it was clear that it had made a difference. Until the ceiling is properly dry, GF will have to wait to do the walls. He made use of the time masking the doors and windows in preparation. Practically, it will have to wait until Monday as the ceiling won't be dry and hard enough to be masked off today.
Never mind. Progress has been good, and there have been no surprises.
