Behr Premium Plus and Behr Marquee are solid mid-range options available at Home Depot and typically cost less per gallon than Sherwin-Williams Emerald or Benjamin Moore Aura.

Our calculator compares all four brands side by side so you can make the call yourself.

Question 7

How often should you repaint interior walls?
