Can you repair a polyethylene canoe?
Again, be conservative in how you use your repaired canoe. Inevitably, the repaired section of hull will be more rigid than other areas and therein lies one of the challenges of polyethylene repair: the innate flexibility of the material.
Can a hole in a kayak be fixed?
We now have 3 boats with gaping holes in them. It isn't very likely that you'll have a kayak with such a large hole, but whatever the size, here's how to fix it. 1. some sort of patch. we had an old trashed boat we could cut up.

What do you use to repair a plastic kayak?
Using a small drill bit, put a small hole at each end of the crack so it doesn't spread. Plastic weld the crack to complete the repair. You will need a plastic welding kit with HDPE welding rods and it works in a similar fashion to a glue gun. Plastic can also be repaired with a lighter or torch and plastic remnants.
How do you fix high density polyethylene?
When it begins to melt, spread the liquid out towards the pilot holes. You must force the liquid polyethylene into the holes so the patch will adhere to the damaged plastic. Once you have filled the pilot holes with polyethylene from the melted patch, pour water on the patch to cure it.

How do you smooth out scratches on a polyethylene kayak?
Use the fine sandpaper and sand back the scratched surfaces gently. Be careful not to scrub off too much plastic from one area – no one wants an uneven surface. The sanding helps smoothen the hull by removing plastic shavings. Using your heat gun or a hair-dryer, gently heat the scratched surfaces.
Can polyethylene be repaired?
One of the universal truths about polyethylene is that it is difficult to repair. Fortunately, it is a material that rarely needs repair, but there will be times. Shallow scratches and gouges are sometimes best lived with. Unless quite deep, they are cosmetic in nature and will not impact the integrity of the hull.
What will bond polyethylene?
However, there are other ways of forming bonds on Polyethylene surfaces. The two best options for bonding Polyethylene are: Solvent Welding, Ultrasonic Welding or Infrared Welding. Industrial Polyethylene Adhesive.

Will epoxy stick to a kayak?
Commonly, plastic canoes and kayaks are made from polyethylene or polypropylene. These low surface energy plastics are hard to bond to, making repairs difficult because the plastic surface inhibits the ability to spread an epoxy adhesive and wet out the surface.

Can you wax a plastic kayak?
Again, if your kayak's hull is made of plastic, you'll likely get by without marine wax – polyethylene and wax don't mix well. And while you can afford to skip kayak wax, a UV protectant spray is a must-have: UV rays can – and will – do a number on your kayak.

What type of plastic are kayaks made of?
high-density polyethylene (HDPE)Most new boats are made of high-density polyethylene (HDPE), which is a thermoplastic, meaning it can be heated multiple times. This makes is very conducive to welding those cracks or holes. Some older boats, think early 2000s Jackson Kayaks, are high-density crosslinked polyethylene (XLPE).
How to make a patch for a droopy drywall wall?
set up your work space so that everything is accessible. 1. put on your gloves. 2. turn on the heat gun or ignite the torch. 3. with the pliers, hold the patch at a corner. 4. using the torch/gun, melt the patch to the point that it is droopy but be careful not to burn a hole in it.
Can you use a torch on a boat?
Now if you want to, you can use the torch on the inside of the boat to transition the plastic of the boat to the patch. This time you're smoothing the plastic of the boat onto the patch. I think this step isn't very necessary unless your patch is leaking. Now all you need to do is sand the patch smooth.
What are the most common structural damage to a poly boat?
The most common structural damage “poly” boats suffer are cracks or linear breaks. In many cases, these are repairable but the process is challenging. You will need the following tools and materials to attempt a repair of this type of damage:
What is cosmetic damage on a boat?
Cosmetic damage is defined as something that impairs the boat’s appearance but not its function. On polyethylene boats cosmetic damage usually takes the form of abrasion, superficial slits, cuts or gouges, and localized dents in the hull panels.
Can you patch a boat hull?
It is possible to weld a patch to your hull but can be a tricky process. As its necessary to melt your existing hull surface at point of repair, the possibility of inadvertently further damaging your hull does exist. If possible,rehearse the process on a couple of scrap pieces of polyethylene before attempting on our boat. For best results, obtain a patch of adequate size from your boat’s manufacturer.
Can you repair a polyethylene kayak?
It’s safe to say that rotomolded polyethylene canoes and kayaks have revolutionized paddling. Boats made of this relatively inexpensive material are incredibly durable and abuse-tolerant as well as near maintenance free. If there is a downside to “roto” or “poly” boats, it is that should they be damaged, they are more difficult to repair compared to their ABS Royalex® and composite (fiberglass, Kevlar®, etc.) brethren. Indeed, some polyethylene boats are impossible to repair and some types of damage pose a major challenge whether it be a “home” based repair, a shop repair, or even factory based.
Can you melt poly with a torch?
torch with open flame is fine for generating heat necessary to conduct repair but it is not recommended to melt the weld rod poly directly with a torch. Use a drill bit as described to melt the rod.
What is a kayak made of?
Inflatable/Folding Kayak Repair. Basically most inflatable kayaks and rafts are made of either a synthetic rubber (that used to be called hypalon), or vinyl (PVC). The term “hypalon” is now history. That basically same material, chlorosulfonated polyethylene (CP), is what most kayak hulls would be made out of today.
What is damage to a rotomold kayak?
Rotomold Kayak Repair. Two of the most common types of “damage” to a rotomold are scratches in the hull or pressure indentations (“oil canning”). Such depressions happen when a sun-baked or super-stressed boat tied too firmly to a rack caves in as the plastic is heated or stressed.
How to repair rotomold cracks?
Rotomold cracks can usually be repaired by “welding” the crack - sealing and filling the area with a hot welding gun/melting rods (NOTE: you cannot plastic weld cross-linked poly’ material).
How to seal a penetrating breach?
A Penetrating breach in the hull can sometimes be temporarily sealed by applying pressure to padding (Such as a small pack or a spare PFD) placed over the damaged area - like applying a compress to an open wound.
How to prevent cracks in weld?
1) Blade expands crack as advanced ahead of hot weld 2) Hot melt rod starting just beyond hole, advancing along heated crack line. 3) 1/8" holes to prevent expansion of crack.
How to stop cracks from running?
TIP: To prevent the rare, but possible extension of the crack during handling, you can drill/melt a small 1/8” diameter hole at each end of the crack to prevent it from “running” farther along the surface. Start the weld just beyond hole, across and into the hole, and then follow along the crack as you apply heat.
