welder by trade and this is the only video i have come across that shows how to properly spin the filler material to achieve a solid bond- way better than just mashing it in! thank you sir-
Finally, a real plastic welding video, not a soldering one. Welder by trade here too. As soon as I saw the swirling I grinned from ear to ear. As it weird that I'm actually looking forward to scratching my new kayak now?
Lots of cheap stuff is made out of HDPE, which is what you need to weld your kayak. There is a triangle molded into the plastic item, usually on the bottom, with a 2 in it if it is HDPE. Gas cans, flower watering cans, and loads of other cheap things are made out of this stuff. All of it will melt into and fill a crack in an HDPE kayak. You can buy welding rods, but you don't have to have one if you have an old plastic gas can lying around.
Had poly craft nearly 20 years never had problem with itfished rough conditions narooma too evens head crossing bars bad seas all conditions still have it love it fished everything from shallows too 40kms offshore if you guys break boats not know how
Great tut and info...A lot like brazing metal just way cooler and with hot air instead of flame..My guess practice makes perfect...Gona get me a bucket fresh clean and not brittle...Cut out a couple stirps for welding rod...then make a few deep scratch and holes in bucket...then Practice the above instructions on bucket instead of KAYAK tell i feel confident.....Be sure Bucket is HPDE 2...
if the plastic is not too thin, try sanding off the high points, then use wax to fill the low areas and buff it out. this does 2 things, it fills in the scratches, and adds a smoother finish which slips through the water nicer.

fantastic. I've got a 2013 Stomper 90 with a long gouge in it, 2mm wide, 0.5mm deep right under the cockpit. I was wondering weather I should infill that like you would on a second pass of your weld. or just leave it. I have the heatgun, I need to get a step down nozle and rods so no rush.
Thanks guys it is a good demo on how to weld, If using a donor boat for welding rods is the size of the rod important, also would you say this produces a boat as good as new or is there always a weak spot?
Thank you for the video. Quick question. I have a small dinghy plastic boat that developed a hole. Does the boat have to be made from HDPE in order to do plastic welding? If yes, how can I tell whether it's HDPE or not?
I’m almost positive that all plastic water crafts are HDPE. If you need a piece of material for the weld or patch. Just look for the triangle or square with number 2 in it. Hardware store buckets, even some detergent containers will be correct materials
