Will polyurethane paints stick to epoxy?

Yes, polyurethane paints can stick to epoxy, but proper surface preparation is essential for optimal adhesion. The epoxy should be fully cured and lightly sanded to create a rough surface for the polyurethane to adhere to. Additionally, cleaning the surface to remove any dust or contaminants will help improve the bond. Always consult the manufacturer's guidelines for specific compatibility and application instructions.
