Hi there,
Thank you for your review, and I am sorry to hear the paint went streaky and chalky, especially after applying 4 coats. I can assure you this isn't the experience we want any of our customers to have. From what you've described, it's possible the new drywall could be porous and soaking up the paint. Because of this, it may be best to prime with our Drywall Primer and Sealer first, and then topcoat with the paint. If you're willing to give us a chance, please reach out to us directly; we'd love the opportunity to turn this experience around for you. -Edith
