Repairing Kayak Holes

If you need to repair a hole in your kayak, go online and look up the model and manufacturer to see if it’s made of linear or crosslinked polyethylene.

For filling holes in a fibreglass kayak, only one kind of epoxy resin is appropriate.

In addition to being used in the manufacture of linear polyethylene, it can also be used to repair broken kayaks.

The majority of modern kayaks are constructed of linear polyethylene.

The planning process for repairing a kayak remains the same, regardless of how damage occurs.

Bear in mind that the material you choose for your kayak will be damaged in the future. Whether or not it can be quickly fixed, as well as the degree to which it can be replaced. Especially any harm to the craft’s structural integrity.

If the damage is serious and could jeopardise your boat in some way, you’ll want to make sure the repair is long-lasting and sturdy – assuming that’s even possible.

The tips below will help you speed up the process of repairing and refinishing your boats.

Common damages and their fixes

A scratch on any external surface would remain a non-structural blemish, whether it’s fibreglass, gelcoat, varnish, or thermoform.

The materials available today are practically impervious to the harshest onshore conditions, without a doubt.

Regardless of how sophisticated the equipment is, it can be damaged by being thrown, struck by underwater rocks, or blown off shelves.

Here’s a rundown of some of the most popular kayak problems and how to fix them.

Taking Care of a Wooden Kayak

If anyone had spent several hours making their own wooden kayak, they would almost certainly weep.

If it’s your boat, you can always call a “doctor at home” to assist you in repairing it.

Almost every time, the same materials were used to build and repair the ships.

If cracked or scratched surfaces are broken or sanded, they can be refinished or fixed.

Rotomold Kayak Repair 

Scratches and oil canning are two common types of rotomold damage.

An indentation may fade over time as the memory of the plastic begins to return to its original form.

Fiberglass Kayaks

Deeper scratches can be carefully sanded or simply covered in resin, while shallow scratches do not need any treatment.

Prior to the application of the repair coating

Until applying the fixing coating, use a blue paint trim tape to mask off the area around the scratch. Make sure the surrounding area is clean and even.

Thermoform kayaks.

Thermoform adhesive may also be used to strengthen chipped or damaged internal shell surfaces and as a scratch filler, as previously mentioned.

For both forms of repairs, Eddyline recommends Devcon Plastic Welder.

Inflatable kayak repair

Synthetic rubber or vinyl are often used to make inflatable kayaks and rafts (PVC).

Kayak hulls made of CPE (chlorosulfonated polyethylene), which has a similar structure to steel, are widely used.

On the cotton decking material available at Klepper shops, consumers can use transparent “Gorilla” tape as a temporary repair.

Some manufacturer also recommend using  “Tear Mender.”

You’ll need to clean up and sand the damage first.

Drilling holes in the edges of cracked pieces may be necessary.

If you try to repair cracks in your hull, they will spread.

This will never happen if you use a pilot drill bit.

Drill a diameter of 18–116 into the plastic at one end of the crack with the tip of the bit.

Replace the opposite side of the crack.

If the crack did not stretch all the way through, a few slits on the surface would suffice.

The other side of the hull is visible because it has not been gouged, punctured, sliced, or thruholed.

Rough up the damaged patch with 80-grit sandpaper to complete the repair.

An 80-grit sheet of sandpaper is an excellent solution.

To close the opening in the kayak, scrape and smooth the rubber band over it.

Scratch the broken area and, if necessary, roughen the cracked area.

We used a cotton ball soaked in rubbing alcohol and paper towels to clean the spot.

Remove a few sheets of paper towels from the roll and gently pat them dry.

Soak paper towels in rubbing alcohol after putting on rubber gloves.

If you don’t have any rubbing alcohol on hand, soap and water will suffice.

To ensure a dry surface, thoroughly rinse it and wipe it with a clean towel.

Squirt water around the soaked-in-alcohol area with a bucket or a hose filled with water.

It’s crucial to wipe the wet area with paper towels after drying it up with water.

As soon as possible, we’ll go over the steps for oxidising plastic with a butane torch.

Light a butane torch to get started.

By moving the torch in tiny circular motions over the damaged plastic, you will allow the flame to come into contact with it.

Cover 12–16 inches per second with the torch to keep the plastic from melting.

Rather than melting polyethylene, the only way to treat it is to oxidise it.

Furthermore, oxidising the kayak’s surface ensures that any filling material you use stays permanently attached to the kayak.
