I was given a kayak but it had six cracks in the hull and would eventually take on lots of water.
I had two options: scrap it or repair it. It didn't cost me anything, so I thought I'd try to repair it.
Is it possible to make a permanent repair using a drill, cloth tape and a hair dryer? Yes - it really does work!
I've made a few river trips in my repaired kayak and there are no leaks.
Step 1: Materials needed
- A drill with a very fine drill-bit
- A reel of fabric tape - this is also known as duct tape, cloth tape or gaffer tape. It's a flexible self-adhesive tape reinforced with a cloth mesh. It's quite cheap and easily available.
- A hair dryer or hot air gun.
- A marker pen
Step 2: Drill the end of the crack
This work is done on the outside of the kayak.
Get a drill and drill a very small hole at both ends of the crack. This will stop the crack getting any bigger.
Step 3: Mark the extent of the crack inside the kayak
This can be tricky, so use a pin to poke through the hull so you can mark the hole using a marker pen.
When you have marked the holes, you will then know where the ends of the crack are.
Step 4: Heat the area to be repaired
Heat the repair area.
Use a hair dryer or heat gun to heat the kayak (or canoe) plastic so that it is hot to the touch. If you are using a powerful heat gun, be very careful not to heat the plastic too much.
