Just to clarify, because based my PM's I was not clear. My main issue is NOT stucco.
resurfacing the little Juliet balcony outside my master bedroom. Currently done in brittle slate tile that has shattered and chipped. Don't care what surface it is, new tile, duradek or whatever.
Main problem is typing it into the synthetic stone exterior of my house. Will need to remove and replace the decorative synthetic stone. That part is 1) where the water will get in and 2) totally visible from the street, so it needs to be done right. This balcony forms the roof of the room below, so any leakage is going straight to the interior of my home.
