Hi SuziN, thank you for your review. I'm sorry to hear about the coverage issue you experienced. Your satisfaction is important to us, and I can understand your frustration. Generally, paint will cover in about 1-2 coats, but porous surfaces and drastic color transitions may need additional coats. However, I'm concerned that you mentioned that an orange vein has appeared and was tough to cover. We want to do our best to help make sure you can achieve positive results. Please reach out to us directly so we can learn more about your project and assist. We look forward to hearing from you! -Lina
