Hi RW12, thank you for your review. I'm sorry to hear that paint did not cover well, and left a heavy texture. This is not normal, and I understand your disappointment. It sounds like the paint was drying too fast. We do not recommend adding floetrol, but you can add 4 oz. of water per gallon to slow down the dry time. Our Marquee paint should cover in one coat when tinted to one of the one-coat colors and applied over a previously painted surface. 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
