Hi there, thank you for your review. I'm sorry to hear about your experience after using the Low-Lustre Porch and Patio Floor Paint. When applied to a painted or primed surface at the recommended spread rate, this should resist rain after just 24 hours of drying. To help resolve this, I suggested removing any loose coating, sanding the edges smoothly, cleaning with the All-In-One Wood Cleaner, and, once dry, spot prime the peeled area followed by two coats of paint.
