Can I use polyurethalne sealer over mnwax polycrylic sealer?

I covered my kitchen counters with Golden Crackle Contact Paper. Really pretty! Didn't want a high gloss look and put on two coats of Mnwax Polycrylic (water base) satin. Only now I'm thinking I do want a little more gloss. Can I use polyurethane sealer over the water-based acrylic? Thanks!
