1. After one coat of paint the wall is no longer the colour of a ceiling that has sheltered a heavy smoker for 20 years.
2. After two coats of paint, the holes Nick repaired last night are no longer visible.
3. After three coats of paint, and a careful clean-up including a long time spent on the carpet with a stanley knife, the walls are bright and clean. We are satisfied and ready for the new bookshelves.
