I am installing a travertine paver deck on a dry set against travertine coping. What type of expansion joint materials do I need to install between the deck and coping? How much of a gap should there be? Any installation instructions would be great. Thanks.

The expansion joint should be 1/2" to 3/4" wide. Use foam backer rod to fill most of the space leaving about 1/2" of depth for a self leveling caulk. My PB uses Sikaflex another popular brand is deck-o-seal.
