If you have a rotomolded polyethylene kayak, you are in luck because this type of kayak is relatively easy to repair. In this post, we will go over the steps for repairing your kayak, as well as some alternatives if repairing it yourself is not an option. By the end of this guide, you will feel confident in your ability to fix your kayak and get back on the water in no time.

Types of Damage You Can Encounter

There are several different types of damage that your rotomolded polyethylene kayak can encounter:

  1. Cracks: These can occur from impacts or stress on the kayak.
  2. Holes: Holes can happen from running into sharp objects or hitting rocks.
  3. Fading: Over time, your kayak’s color can fade due to exposure to the sun and other environmental factors.

It’s important to identify the type of damage your kayak has so you can determine the right repair method.

Tools You’ll Need for the Repair Process

Before you start repairing your rotomolded polyethylene kayak, make sure you have the following tools:

  • Sandpaper: Choose a grit that is appropriate for the damage you are repairing.
  • Solvent: Use a solvent that is safe for polyethylene, such as acetone.
  • Fiberglass cloth: This will be used in the repair process to reinforce the damaged area.
  • Epoxy: Choose an epoxy that is suited for repairing polyethylene kayaks.
  • Masking tape: Used to protect areas of the kayak you don’t want the epoxy to touch.
  • Paintbrush: Used to apply the epoxy to the fiberglass cloth.

With these tools, you will be able to repair most types of damage that your rotomolded polyethylene kayak may encounter.

Steps for Repairing Your Kayak

Here are the steps to follow when repairing your rotomolded polyethylene kayak:

  1. Start by sanding the damaged area of the kayak with sandpaper. This will help the epoxy adhere better.
  2. Clean the sanded area with a solvent like acetone before applying the epoxy.
  3. Cut a piece of fiberglass cloth that will fit over the damaged area with some overlap. The cloth should be saturated with epoxy before application.
  4. Lay the fiberglass cloth over the damaged area and use a paintbrush to apply epoxy to the cloth, making sure to completely saturate it.
  5. Smooth out the epoxy-coated section with a putty knife to create an even surface. Let the epoxy cure for the recommended amount of time.
  6. Once the epoxy has cured, sand the repaired area until it is smooth and even with the rest of the kayak.
  7. Finally, apply a layer of gel-coat over the repaired area to match the color of the rest of the kayak, if necessary.

Remember to wear appropriate protective gear when working with solvents and epoxy.

Alternatives to Repairing Your Kayak

If repairing your rotomolded polyethylene kayak yourself is not an option, here are some alternatives:

  • DIY fixes with duct tape: While not a long-term solution, duct tape can provide a temporary fix for small cracks or holes.
  • Hiring a professional to fix your kayak: If you don’t feel confident in your ability to repair your kayak, consider hiring a professional who specializes in kayak repairs.
  • Replacing the kayak altogether: If the damage to your kayak is extensive or you’ve had it for a long time, it may be time to replace it.

Remember that proper care and maintenance can help prevent future damage to your kayak. It’s important to inspect your kayak regularly, store it properly, and avoid exposing it to extreme temperatures and harsh weather conditions.

It was a long process, but Alice was patient and meticulous. She sanded the damaged area, applied the solvent, and cut and laid the fiberglass cloth. She then applied the epoxy and let it cure.

Finally, Alice stood back and admired her work. Her kayak looked as good as new! She couldn’t wait to take it out on the water and make new memories.
