Hi denkigroove, thank you for your feedback. I'm sorry you didn't get the coverage you were expecting from your paint. Although our Premium Plus Ultra Stain-Blocking Ceiling Paint does have a built-in stain blocking primer, it's not guaranteed to cover in a specific amount of coats. Multiple coats may be needed to achieve your desired coverage. I apologize for the miscommunication regarding the coverage. For coverage in one coat, I would suggest using our Marquee Stain-Blocking Paint and Primer Ceiling Paint, as it's guaranteed to cover in one coat. Customer satisfaction is important to us. So, please feel free to reach out to us directly if you need further assistance. Our Customer Care team would be happy to help! Have a wonderful day! –Joanna
