Hello John, thank you for your question regarding our Durock Next Gen Cement Board. It is not necessary to finish the fasteners used to install the Durock, but this is how you finish the joints:
Use either the Latex Modified Thin Set Mortar or the Type 1 Organic Adhesive and a Fiberglass Tape marked specifically for use with Cement Board. Apply the tape to the all joints and then spread a thin layer (just enough to cover the tape) of the Mortar or the Adhesive. Allow the joints to dry completely before beginning to install your tiles, stone, etc.
