Anybody have a recommendation on caulk?? My pool deck is up against my poured concrete foundation. Here is the layout. Looking overhead, there is the foundation, 1/2 inch expansion foam, decko drain, stamped concrete deck. The foam allows for the expansion and contraction of the deck. As designed, you peel off the top layer of the foam strip....about 3/4". So, between the poured concrete foundation and decko drain, I need to caulk. I supposed I need the kind that goes between poured concrete decks and brick coping??? Can I get this at Home Depot or lowes?? Any advise? Thanks, Doug
