    Pick up some backer rod from the hardware store, push it in the gap then use the Sikaflex to top coat it. Backer rod is a flexible foam product. You can find it where they have the insulation usually.

    Thanks! Is the backer rod good for vertical gaps?

    Yes. It's just extruded foam. Cut it with a pair of sizzors or a utility knife.

    If the gap is too fat for the backer rod to wedge itself tight, you can double it up and twist it like a spiral to make a big fat piece of it.
