I'm fixing stucco on an old house and it appears as though they literally just added stucco onto cement board with asphalt kraft paper in between. I have to remove a piece to add in new cement board that broke on the back. Can I just stucco directly onto the cement board without a mesh? I didn't know this was possible, but apparently the builders did it! Also, can I forgo the paper? It doesn't seem to be doing much if anything at all - water doesn't sit on this surface but rather beads off as it is hanging (the area in question is a soffit).
