Yay congrats on the house! We’ve been using the 2.5 Behr flat white from Home Depot on our ceilings and they look really good! It’s an 89 year old house so we used flat to hide imperfections in the ceilings. They’re plaster. It happens. Also, Sherwin Williams is having 30% off paint through the 31st, which puts the less expensive gallons on par with Home Depot and it’s better paint.
