Redoing the entire ceiling
Got home from work and straight into warm working gear, lit the fire and by seven the house was starting to warm up.
Gave the ceiling a sand in the smaller of the two bedrooms and managed to paint the entire ceiling and some of the walls where I’d rebadged some bits and painted on the stain resistant paint.
Let the paint dry then painted on a second coat onto the walls and ceiling.
All looking pretty good.
