Generally, it’s important to seal all cracks:

1.
between the coping (rock, brick, coping stone) and the tile. *note picture below labeled “mortar joint”.
2.
between the coping and the deck. *note picture below labeled “deck-o-seal”.



The “deck-o-seal” is actually a water barrier. “Deck-o-seal” is a brand name for a two part self leveling caulking mix which is poured into the space between the coping and the deck. A sand base is used to fill up most of the space and the deck-o-seal is poured on top of the sand (rules are no deeper than the width of the joint). If applied correctly and if the deck does not move too much, this should last approximately 5 years before needing to be replaced.

If you see visible cracks in the caulking-like substance, depending on the size of the crack and length, a small amount of clear 100% silicone can be used to seal the crack as a temporary fix. Otherwise, it is recommended to remove the old deck-o-seal and replace with new.

If you’ve never done this before it is highly recommended to hire a professional.
