I've got to join two durock panels when assembling my hearth. Durock instructions note that you should join panels together and
Fill joints with latex-fortified mortar or Type 1 organic adhesive and immediately embed alkali-resistant, fiberglass mesh joint tape.
Is this the best method for a hearth? Is fiberclass mesh tape ok in this application? Should panels be butted up next to each other, or do they still need an expansion gap?
