This instructable provides a simple and affordable method for fixing cracks in plastic kayaks or canoes using only a drill, cloth tape, and a hair dryer. Plastic kayaks are durable, affordable, and offer great value, but not all kayaks are created equal. Different types of plastic may require different repairs.
A simple DIY technique from Chad Hoover demonstrates how to fix scratches, grooves, and gouges on polyethylene kayaks using a spoon and a heat gun or plastic welding iron. Learning how to fix a cracked kayak can take time, but the key is providing direct and constant heat. Basic repairs and maintenance to your plastic kayak or canoe include fitting keel protector tape, basic plastic welding, and cleaning up the hull.
To patch your kayak, follow these steps:
1. Clean the damaged area with mineral spirits to remove wax, oil, or other contaminants. Use 60-80 grit sandpaper to scratch the surface around and a little bit beyond the repair. Flame treat the edges of the patch and the edges of the hole. Spread a generous amount of epoxy around the edges of the crack, then stick on the first layer of fiberglass and smooth it into the epoxy.
2. Melt some of the plastic into the patch and smooth it. Use a lighter to melt the plastic, allowing drips to fill in the scratch. Use a spoon or screwdriver to shape or spread the plastic, and hold the patch at a corner using pliers.
In summary, plastic kayaks are durable, affordable, and can be fixed using simple techniques. However, it’s important to note that not all plastic kayaks are created equal and that different types of plastic may require different repairs.

Whether you need to know how to patch a hole in plastic or join two pieces together, using the right adhesive is key.
A few drops of glue are enough to make broken objects look like new.
The best adhesive to fix your cracked plastic depends on the job at hand. Some products are better suited for large projects, while others can bond only certain kinds of plastic. Some adhesives, such asLoctite Plastics Bonding System, are formulated to bond difficult materials like polyethylene, polypropylene, and Teflon. Others, like the epoxyLoctite Plastic Bonder, offer different advantages, including versatility and water resistance. You need to consider whether your adhesive is needed for interior or exterior applications and how you use the object you want to repair.

Can you repair a plastic kayak with fiberglass?
If the break in your hull is only a split or slight tear, three layers of 4 oz fiberglass or six layers of 2 oz fiberglass are usually adequate for this type of repair. Multiple layers of light fiberglass fabric are best. Two layers of 4 oz fiberglass (or four layers of 2 oz) are applied to the inside of the hull and one layer of 4 oz (or two layers of 2 oz) are applied to the outside of the break to complete a repair for canoes and kayaks. More layers are used on the inside because higher tensile loads are expected on the inside if there is an impact on the outside.
A good mail order source for light fiberglass fabrics ranging from.5 oz to 10 oz and other composite materials is CST – The Composites Store.
How long do plastic kayaks last?
The stated maximum UV resistance lifespan of the high-density polyethylene used in our current production process is around 12 years; this is inclusive of many incremental developments we have made in conjunction with our suppliers over our 35+ years of rotomoulding experience to produce the optimal plastic alloy for canoe & kayak production and assumes average use as well as consistent and proper maintenance. This figure is also in relation to areas of low-UV concentration such as the UK and changes dramatically in areas of high-UV concentration such as Australia.
Pre-2004 generations of Capella were manufactured by a thirdparty, prior to Pyranha Mouldings Ltd.’s acquisition of P&H Sea Kayaks, andtherefore we cannot verify the exact alloy of polyethylene compounds or theirperformance with regards to UV resistance.
We are certain, however, that even using a conservativeestimation of UV resistance given the available polymer technology during thetime of production, at over 16 years old, these models will have long sinceseen a drastic reduction in structural integrity due to UV degradation.
Can you plastic weld a kayak?
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).
A crack in your beloved kayak doesn’t mean game over. Welding up a crack, or even a hole, is possible with the right tools. Before you start it is important to know what type of plastic your boat is. 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). Being a thermoset plastic, it can only be heated once and will likely burn if you try to weld it.
Plastic Welding Tools. I think many people are scared to fix a crack in their boat because of the word “welding.” However with a little practice it is a pretty easy and straight forward task. Here are the tools you will need.
- Drill and small drill bit
- Metal scraper
- Pliers
- Knife, box cutter, or razor blade
- Heat gun or welding iron
- Welding rods or plastic from your boat
- Rubbing alcohol or mineral spirits
How to repair holes in hard plastic?
When plastic is punctured, it seems tricky to fix at first. Luckily, there are ways to fix and patch plastic without completely replacing it. A makeshift cement from super glue and baking soda can fill small holes in a pinch. Larger holes in plastic can be filled with melted plastic or epoxy. No matter which method you use, you’ll be able to plug the hole and pretend it never even existed.
Use a sturdy piece of scrap cardboard that be easily removed later and attach it with tape or a hand clamp. Placing a back piece behind the hole prevents any material from running through the hole.
If you cannot fit cardboard between the plastic, like if the hole is in a gas can, this can still work, but it may not have as solid of a hold.;

I’ve always loved the outdoors and fishing. Now that my boy, Reece, has also caught the fishing bug I decided it was time to get a canoe so we could do some more outdoor exploring.
Update: Leslie has also caught the fishing bug. We vacationed in Minnesota this summer and she was loving the excitement of reeling in some bass!
A canoe was not really in the budget this year though, so I decided to keep an eye out for a cheap one on Craigslist. I saw a lot of $500 dollar type canoes, but then one ad caught my eye… $60 for an Old Town Tripper canoe. What a deal for a canoe from a reputable company. But then the fine print… “Large Crack…. Does Not Float”. But, Reece usually says that “Dad can fix anything”, so why not give this a try too!
What is the best way to repair cracked plastic?
If you need to reconnect a crack in plastic, you can use plastic glue specially formulated to bond plastic surfaces. Plastic glue is often used for making models, so it is easy to use and safe to handle. Alternatively, use hot water for small cracks or plastic slurry or weld larger cracks.
Use plastic glue to fix small cracks in plastic. If you need to reconnect a crack in plastic, you can use plastic glue, which is specially formulated to bond plastic surfaces. Plastic glue is often used for making models so it is easy to use and safe to handle for adults. Make sure you have enough to connect the whole crack, you don’t want to have to stop after you’ve started applying strong glue!
You can use most super glues as well, but check the packaging to make sure it can be applied to plastic.;
Should I wax my plastic kayak?
- Clean your polyethylene kayak with mild soap and water.
- Use 303 Protectant or a similar plastic protectant to guard against UV rays and to help your boat shine.
- For composite boats, you should apply a car wax that is recommended for fiberglass from time to time to protect the finish.
