First, the deck will be prepared, and underlayment will be placed to protect the surface from damage. The first tile can be positioned with the crown facing up. A nail can be driven into the base of the tile into the batten. Mortar should be placed underneath the tile to provide support. Another tile can be installed on top of the inner end first, and the second tile can be nailed into the batten just like the first. This process continues until all tiles are installed.
