Yes, polyurethane will stick to epoxy when used together in a project.
Yes, epoxy will stick to cured epoxy.
No, it is not recommended to put epoxy over polyurethane for a smooth and durable finish. The two products may not adhere well to each other, leading to potential issues with the finish. It is best to stick to one type of coating for optimal results.
With a polycarbonate glue. Try Weld On # 3 or #16.
Yes. Because a chemical bond is no longer possible because the epoxy coating has dried, a mechanical bond is required. This merely means that the cured epoxy must be lightly sanded before applying the next layer: the first coat should have a matt, nearly white finish.
I wouldn't, it will not stick well.
No, it is not recommended to apply water-based polyurethane over linseed oil for a protective finish on wood projects. The two finishes may not adhere well together, leading to potential issues with the finish. It is best to stick to one type of finish for a consistent and durable result.
Epoxy glues would be best.
A metal epoxy is an epoxy that will glue matals. Two good ones are J B Weld and Pow-R-Stick.
Epoxy adhesive can stick to almost anything except some PTFE's and some of the new polyethylenes. It can stick to metals, woods, most plastics (except the fore-mentioned) and stones and rocks.
Use 'Slime' rubber cement.
No, it is not recommended to apply oil-based polyurethane over water-based polyurethane as they are not compatible and may not adhere properly. It is best to stick with the same type of polyurethane for a consistent and durable finish.
