Can Elastomeric or Acrylic Stucco be applied on top of painted old stucco to seal it?

Cracks in stucco are leaking rain into the wall. We fixed the affected old wood studs, but need to address the source. I can see cracks in the stucco where the water is seeping through… can this be fixed with a skim coat of Elastomeric or Acrylic stucco? Which? (Trying to fix this without having to remove all the old stucco)
