There are screws made specific to set cement board, sold at Hd and Lowes right around where the boards are stacked. Or you can use 1 & 1/4" galvanized roofing nails which also specified as acceptable by the CBU manufacturers.

I want to hang some pictures above a fireplace which has been constructed I think of cement. I can't get the 3M Command strips to attach. Do you have suggestions? The house was built in the early 1950s.
