I am going to be painting a concrete block house with a smooth stucco
finish that has lots of peeling paint and a couple of hairline
stairstep cracks. Does a primer serve the same purpose as a sealer for
prepping areas where the paint has been removed when pressure cleaning
or will both a sealer and a primer be needed?

Any recommendations for primers and sealers for this kind of
application?

THanks.
