I need to match new stucco to old stucco. The problem is that I am tearing off 3/4″ sheathing and replacing it with 1/2″ CDX in a few areas (shear walls) as part of a earthquake/remodel project. What is the best way to furr out the new wall so that I end up with 7/8″ of stucco in the same plane as the old stucco? Furring stips over the plywood with paper/lath nailed over it, 1/4″ foam board (EIFS nightmare scenario?) over the plywood followed by paper/lath, or a layer of 1/4″ ply over the wall? If I go with a layer of 1/4″ ply, I may as well use 3/4″ cdx for the entire shear wall (price wise).
Thanks
Andrew

Use stucco wire over tar paper. Then use furring nails (the ones with the round cardboard paper spacer). It gives you thicker stucco with more strength and less cracks. Self furring lath has its wire too tight to the paper, not allowing as much cement to grab on the wire.
I plan on doing as you described, but I need to fur out the sheathing a little or I'll end up with really thick stucco on the new part (because the sheathing is only 1/2", not 3/4" as on the rest of the house).
If its not too late, take a 2X and rip furring strips to nail over the face of the studs, then nail the plywood over that.
