I have begun making cosmetic repairs to the interior of my home which was built in the 50s. I've got brick veneer on the outside, cinder block inside and then a layer of either chicken wire plaster or just plaster applied directly to the block. After removing the top layer of plaster of a cracked area under a window sill corner, I discovered a settlement crack about an inch wide. The home is no longer settling so I know the crack isn't enlarging. My uncle who is a contractor instructed me to fill the gap with hydraulic cement, dry, apply a few layers of durabond and then top with a coat of mud to finish up the top layer.
Would this be an adequate repair to make sure it's done "right" and not just a quick patch job? Not trying to screw over the next owners.
UPDATE: just needs finishing sanding and primer/paint
