I want to install some lap siding on my So Cal home which is a common stucco and wood tract home. My question is concerning the proper installation of lap siding. I am considering using a Lowe’s product called LP Smart Side. It is a lap siding made with fiber glass and cement fibers. I want to install this lap siding directly over the stucco siding. Is that a good idea? What would be the downside? I would install trim boards (probably 2×4’s) on the corners for the siding to butt into. Is some kind of vapor barrier needed under the siding? How would you install the building paper over the stucco? Can roofing paper. say 30#, be used?
Suggestions and comments welcome.

Well BobD, the only real answer is to treat it as new construction. By this I mean there is no easy way out. Start by nailing furring strips to the wall 16” on center. Then sheath over the furring strips. Now follow the local building code for your area, Tyvek I would think, then the siding.
The reason for all of this is to give you a flat surface to work with. Use an 8’ level to make sure that the wall you build over the stucco is flat and true. Any flat board siding, wood, vinyl or cement will sure imperfections. Unfortunately, you can not just nail your siding directly to the stucco.
