Hi there, thank you for your review, I'm sorry to hear that after 24 hours, the paint still isn't dry. Typically, the paint should be completely cured in 24 hours, but cooler temperatures and higher humidity can increase the drying time. Customer satisfaction is important to us, and we appreciate your feedback. Please feel free to reach out to us directly so we can learn more about your project and assist. We look forward to hearing from you! -Ronald
