We filled in the gap with the caulk. THe thing was, and we didn't think about it until after the fact... when the deck contractor poured the deck, he applied the foam around the perimiter of the coping. It had some sort of adhesive which kept it stuck to the coping while the concrete was being poured. When we removed it and used the caulk, we found after one season, the caulk seperated away from the coping. We believe this may have been due to the adhesive which was left on the coping when we removed the foam. So now we need to pull it out and do it again. So, how do you easily remove the caulk, and do it over.
