How to Repair a Kayak With Marine Goop

Marine goop is a specially designed silicone intended to seal products that are regularly doused with or submerged in water. Marine goop is not always ideal for repairing a kayak, as it remains flexible even after curing; however, by the same token, it is often a suitable product to use for sealing any cracks and holes in your kayak. You can also use it to seal the rims of your kayak's cargo hatches and the spaces between its bolts and plastic.

Instructions

    • 1

      Sand the damaged or leaking area of the kayak with short, stiff strokes. You want the plastic to discolor a little and become whitish. Marine goop adheres to polyethylene plastic best when the surface is rough.

      Pour rubbing alcohol on the sanded area and wipe it clean with a paper towel. Inspect the sanded area for particles of plastic debris. If it is completely clean, allow the rubbing alcohol to evaporate before you apply your marine goop.

      Squeeze the marine goop out of the tube onto the damaged area of your kayak. Once you have a substantial amount of goop covering the damaged area, spread it around evenly with a plastic knife. Allow the goop to dry for 24 hours before exposing it to water.
