I did a living room, hallway and kitchen on Monday & Tuesday, yes it took 2 days thanks to the customer providing the paint. Usually I don't run into problems with this but this was one of those situations where work is slow so I underbid due to the fact that cheap paint and dirty walls = double coating everything and possibly having to go back and retrim the kitchen again. No matter how long you have done this you always have that one job where the profit will never be enough. I am not going to lose money on this job, but I should have made alot more.
