We are gutting the first floor of our house and removing all doors, cabinets, trim (except crown), flooring, furniture etc. The house will be empty. I will need to paint the walls, ceilings and crown and plan on using an airless sprayer. So my questions is -- "what is the best order to paint those three items?" They will be different colors and/or sheens. It is about 1400 square feet with 10' ceilings. While I am not opposed to rolling the walls or ceiling I do not want to brush the crown. I have a Graco fine finish tip for the crown. Thanks in advance.
