Fully cured, unfinished concrete can be finished with paint or a concrete stain after being cleaned with a power washer to remove dirt, grime stains and any residue from old sealers. You may need to repaint and use a sandblaster or stripper with a chemical remover to remove peeling paint. Be sure to clean out cracks and wet-dry vacuum or blow out dust with compressed air before caulking the cracks.
Stucco:
For stucco finishes, a simple masonry cleaner may be all you need. First, hose off the loose dirt and apply the cleaner while the surface is wet. If the surface still looks dingy, consider having the stucco re-dash the finish by having a contractor either brush or spray on a new cement surface. It's probably not a good idea to power wash stucco as it can be risky and can blast off the finish.
