Painted the ceiling white yesterday.
For bathroom and mudroom, I used Behr flat enamel Ultra White and for the new porch Behr's Ceiling Paint, ultra white.
Rule number one: If the project is big enough to get out the roller - buy a gallon can, nothing smaller.
Rule number two: Paint in day light. No spotlights in the world are as good as day light.
The photo I took could just as well have been of a polar bear in a snow storm, so there is no point posting that...
