Yes, both oil and water-based polyurethanes will adhere well to an item coated with acrylic paint. If it is a polyurethane paint, dull the surface prior to painting.

Can you spray clear polyurethane over paint?
what kind of paint?? How long has the original paint been on there? Many times, the "vehicle" (solvent) in the polyurethane will cause the existing paint to curdle or wrinkle if it is a water based/latex paint. If it has been on there a long time though, you might be able to get away with it. See if you can test a small spot that is not exposed or visible first. Even if it "tests" OK, it still might have a tendency to pull the existing paint up when you get it on a large area, so be careful

If your painted cabinets were prepped but the paint scratches easy can you polyurethane over to help seal them?
If the paint scrathes off easily then it wasnt prepped properly. I dont recommend polyurethane over paint that is peeling. Your best bet is to prep them properly and repaint. First strip all the old (new) paint that is peeling down to bare wood. You should prime with a good oil based stain blocking primer like Kilz. After that fully dries any good paint will do, but an oil based paint will hold up better over the long haul. If you decide you are going to try and coat the existing job, then use varnish instead of polyurethane. But I highly advise against doing this.
