How to Fix Cracked Surfboard Leaking

A cracked surfboard will halt the progress of even the most accomplished surfer. A crack in a board will allow it take on water and throw off the balance of the board. Repair shops can charge twice what it would cost for you to fix the board yourself. So the next time you crack your surfboard, fix the crack at home to save yourself some money.

Instructions

    • 1

      Purchase surfboard repair resin. Decide whether you want to use polyester resin or epoxy resin. Do not use polyester resin if you have an epoxy-based surfboard, as the resin will eat away the polystyrene core of an epoxy board.

      Allow your surfboard to dry. If the interior foam of your surfboard is wet, this could take up to a week in humid weather. Clean your dried surfboard of dirt and wax.

      Sand the area around the crack in the surfboard with a sanding block. You want to sand an area at least 1/2-inch wider than the crack all around the crack in the surfboard.

      Mix the repair resin and the catalyst from the surfboard repair kit in a large bowl. Your repair kit may provide mixing bowls.

    • 5

      Cover the crack in the surfboard with the repair resin mixture. Overlap the cracked area with resin to include the entire sanded area. Ensure that you completely cover the crack with resin and cover the repair area with cloth. Wait for the resin mixture to harden. Depending on the size of the crack, this may take several days.

      Rub the entire repair area with the sandpaper provided with the repair kit. Apply the sandpaper evenly to the repair area to smooth the entire area.
