I'm a drywaller and I'm curious about why primer is necessary over new sheetrock. If I'm using a high-quality flat paint, do I still need to apply primer first? Would love to hear your thoughts!

Think of primer like a sealant for your new drywall because sheetrock is pretty porous. Priming before you paint is usually more cost-effective—you’ll end up using less paint overall, and it'll stick better, preventing any uneven finishes later on.
You hit the nail on the head—paint doesn't adhere well to bare drywall. Primer is thicker and gives the paint something to really grip, plus it evening out the different surfaces of drywall and any mud. If you skip this step, you might end up with a splotchy finish that's not pretty!
Absolutely, you should use primer! It really makes the painting process smoother. I learned this the hard way—I used two coats in one room and just one in another, and I can tell you that the room I primed went much quicker. Trying to paint directly on sheetrock is a recipe for using way too much paint, and primer is definitely cheaper than all that paint!
That's true! I kind of questioned OP's knowledge too, but this is a common oversight.
Exactly! It's such a simple step but makes a huge difference in the final look.
