stucco direct on PT?

Will portland/stucco adhere to ACQ without lath? Its for door/window trim, part on existing block, part on the bucking.

It won't work without something like wire lath/mesh to hold the stucco in place. The expansion and contraction of the wood will cause cracks and loss of attachment.

If you do not have some method to span the joint between the PT and concrete, a crack will show up there also.
