    Sounds like you may have to sand and start again. Dull spots in polyurethane floors usually indicate that the finish was not applied carefully or the applicator had a dry spot on it. You can screen and coat- this is a procedure where the floor is lightly sanded (or screened) with a floor maintainer or buffer, instead of a floor sander. This light sanding evens out the finish, cleans away debris, and roughens the surface, so another coat of finish will be able to properly adhere to the existing finish.
