Hi David, thank you for your review. I'm sorry to hear about the glossy finish and poor coverage. It is not normal for the flat finish to look glossy. Typically, our Premium Plus Paint will cover in two coats, while darker colors and porous surfaces may require additional coats. Customer satisfaction is important to us, and we appreciate your feedback. Please reach out to us directly if you need further assistance, our customer care team is happy to help you! -Giovanna
