Our old stucco house is in need of a cosmetic refresh. I don't want to paint it, and start that cycle, and it's fine structurally, so a complete new coat would be overkill. It's just really washed out and looks bad.
use a clear sealer, try it in an inconspicuous spot first. I did this on a stucco outdoor grill area brings it back to life. Use a natural finish not glossy.
