Hi John, thank you for your review. I'm sorry to hear the Multi-Surface Roof Paint didn't provide the coverage you expected. This is not the experience we want for our customers and not the performance to be expected from this paint. This should cover 250-450 sq. ft. per gallon, depending on the surface texture and porosity, when applied at the recommended spread rate. Nonetheless, 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! - Randy
