Occasionally we have customers bringing boards in for repair, mentioning that it has previously been repaired but is now “leaking”
We had one such case recently, with a centre fin box looking a bit suspicious.
Here’s what we found upon investigation:
Unfortunately, this accident can (and does) happen quite easily. The board that was brought to us is an epoxy construction – meaning the blank used to shape the board is polystyrene foam and epoxy resin was used to glass the board.
The industry standard resin used to laminate surfboards is polyester resin – this contains a chemical named styrene, which will melt polystyrene upon contact . . . in this case, a fin box has been re-set using polyester resin, which in turn has melted the foam around and below the box. You can see in the first picture that the foam has melted all the way down to the deck of the board (through 5 inches of foam!)
