Step 1: On the inside if accessible, melt the mesh on the inside without preheating all the surface. Tip 1: If using the iron, Use the wire brush frequently to clean the tip of the iron (you burned the plastic) Step 2: Use the but end of the screw driver to smooth out the surface. Step 3: Add more plastic to cover the mesh patch. Step 4: On the outside use the heat gun lightly and the but of the screw driver to blend & smooth out the plastic surface with a light twisting motion. Step 5: sand with 100, then 220 then 400 if available. Step 6: Reheat with heat gun to make sanding marks disappear.
Yes... To some people, this repair may seem somewhat crude, and not particularly attractive. But to others, those self-reliant and inventive people who like to FIX things instead of just sending them to the landfill... it's its own kind of beautiful.
Liquid laundry detergent jugs and usually made of HDPE plastic (recycle #2) and come in many colors. They work as good as mike jugs and can make better looking repairs.
They sell welding sticks in matching colors on amazon for $12 for 5 feet total length and 2 packs total should be enough to do the two cracks most likely. They look much better and are easier to use already being in sticks.
Incase anybody is unsure about this, I just did it. I never have done it before. Had a large part of the hull missing. An inch wide and 8 inches long. More or less. I used a gallon water jug and a soldering iron. I was surprised at how easy it is to fix. You literally melt plastic over the crack or hole until it is sealed. Whence it is sealed, you can add more to smoothin it out if you want. It certainly isn't a pretty job. But it really really gets the job done. Tip: use the soldering iron in a swirling motion to really fuse the plastics together. Go try it now! Wear a mask or two.
Thanks for the vid! I was able to repair a 3" x 1/2" hole in the bottom of my orange HDPE canoe with a tide bottle, some hardware clothe, and a hobby iron with wedge tip. My process: Cut hole to a clean shape (mine was a rectangle). Cut 3 pieces that fit that hole with a 1/4" plus on every side (to weld in). Cut one larger piece, and some hardware clothe/mesh to match that. I attached the larger one inside the canoe over the mesh and melted it in to give support, and to have something to press against while repairing from the outside. Circular motion helped to melt the surrounding area, then work in the new plastic. Plastic stir-welding if you will. Once this was complete, I turned to the outside of the canoe and laid one of my cut strips into the hole and fused it with the mesh while working it into the sides. I used the spare pieces like solder and filled in any indentions to create as smooth an outer surface as possible, since snags could weaken the patch. Result: looks great and watertight!
Nice job. I have an old Coleman scanoe then I've been meaning to take out for more than a decade. I had gotten it from a friend and it was already cracked. I've left it up and overturned so it hasn't gotten any worse. I tried fiberglass as you said it won't stick for any length of time. In the middle of your video, I stopped and got an iron and plastic kit, and then jump back on your video to follow what I was supposed to do with it. Just waiting on the mail. Can't wait to get this scanoe in the water. Thanks.
Bear in mind that the cracks are also a result of how the seat arms were bent resulting in them putting pressure on the hull. When taking the seat off you should bent the arms slightly so that they come in and straighten out before they rest against the hull before putting them back in.
I've got an opportunity to get a Coleman Scanoe for a really good price and it has a crack in it almost identical to what you just showed. After watching your video and reading some of the comments I think I'm going to go ahead and commit to this Scanoe. Thank you so much.
How well did your repair result? Durability? I just acquired a Coleman Crawdad with cracks that I'd like to repair. In my recent research on how to repair the RamX material of the Crawdad (the scanoe also being made from ram x), some persons have said that the HDPE 2 does not fuse well with RamX.
@@dennisedwards8954 my repair turned out ok. Got a video on my channel. Got a 7.5 hp outboard shortly after picking up my canoe. Worked on it for a while and just as I got it to fire the weather turned to winter. So put it all away for the season. If you use a plastic welder, don't get impatient & use a propane torch to speed things up.
With thanks to you and your video, I've repaired our old but faithful Coleman Scanoe! We had to leave it on the shore of a remote NW Alaskan river that was simply not paddlable in a heavily loaded canoe! We helicoptered out, and came back by snowmobile the next spring to retrieve it, and apparently a grizzly had tried sampling both ends of it above the snowline! I have now repaired all the tooth holes, much to my doubting husband's surprise! Is there some way to add before and after pics?
I am a bit late, but I do not advise this technique. First off, to drill a hole was good. The mesh is also a good idea, but maybe fill the gap first. Get a good heatgun (one you can set to a fixed temperature). Forget the plastic welder / soldering iron, you will burn the PE faster as you wish. Use the PE rod you have and work it in circular motion into the crack, pulling material from one side to the other. Oh, I almost forgot... Clean the crack first. By cleaning I mean, take a sharp object and scrape material out. Like this you have "fresh" material to weld on. Do this a few times, then bring in the mesh.
I bought that same cheap Chinese welder with the weak tip. It broke on the first use! Milk jugs are low grade polyethylene, will be a bad weld. Use 5 gallon buckets.. they come in all colors. You can buy buckets at Lowe's, Home Depot or get them free. Paint, spackling, plaster, etc. Check with deli's they get pickles in them and might just give the buckets away.
We found that the mesh overtime rusted and broke down (We repaired about ten Canoes) it made for a real mess when I tried to repair them again. Next time I will find either Stainless mesh or will work in Fiberglass mesh. Either way, I was not happy with the steel mesh.
Great Video I went to Lowes Home Improvement And Bought some Plastic lids that are made for the 5 gallon buckets, the plastic lids are HDPE and seem to have a little better density to them, to me it made a better weld, but either will work, they also have small packs of screen wire to help with the repairs. I also used the screwdriver on top of the welding tool (triangle tip) to help apply pressure and not brake the tips on the welding tool.
@@Makify1 You can get special epoxy paint for plastic canoes which holds extremely well and actually puts a protective coat on you canoe hull. But a quart of it probably cost more than you paid for the canoe.
I had a 17 ft. scanoe that cracked at 2 locations, don’t store those on their sides, they start cracking at the rivet holes. I tried hot air gluing the crack and they expanded so quickly that the scanoe was a loss. I cut it all up in pieces and tossed it. I had a motor on it so it was registered with DMV, I wanted to cancel registration and DMV wanted to see the salvage receipt or sales receipt like it was a car, I told them I cut it up and threw it away, they couldn’t grasp that concept. Then I asked them what happens when a boat sinks? You still want to see a receipt?😊 The early Coleman’s polyethylene plastic is a more linear polyethylene that melts at a lower heat level. Newer HDPE responds better to heat welding. I bought a better fishing canoe after my failed repair.
Good video but you can find welding sticks easily online in the color you want for cheap. They are on amazon for less than $12 for 5 feet of sticks. (5 1ft sticks) I got the green color to match the canoe for 2 of the same canoes as you that I have. Using the milk jugs does look ugly. I also used the metal suture/staples instead of the mesh which get installed below the surface with an inexpensive tool.
I recently found a kayak in a river, it's a pyranha freestyle from 1983 it had a crack in the plastic which I fixed, Ive cleaned it and it seems fine now but is there anyway I can test to make sure it's still usable, the colour still seems ok (yellow) but some parts show shadows from the float and things inside. any advice would be greatly appreciated.
I see some of your comments about epoxy not sticking well to the plastic canoes. Have you tried flaming the plastic on the boat first? it changes the molecules for just a short time but allows for the epoxy to bond to it if done right. Flaming, not heating.
They are not the same materials are are not going to actually mix and become one like welding hdpe to hdpe. What you are describing just sounds like more work. You are looking for harder solutions when welding this way is easily enough to begin with. Are you invested in epoxy stock?
Plastic grocery bags are the same type of plastic stack them up and heat them in the oven to about 250 degrees they will melt togeter put was paper above and below them. and a metal pan on top so they are mashed together.
i have a mad river adventure 14 and have a crack pretty similar to the one you have. The canoe is all one single molded piece of plastic and the crack has occurred on the lower right supporting side of the front seat. Has this held up for the past year? the crack is a spider web but overall about the same size as yours. Any other suggestions or tips for me?
Yes, most any adhesive will not bond and hold. Many people have had such adhesives fail. Welding as he is doing is actually fusing and mixing the two materials together to become one and as strong if not stronger than the original hull. It is absurd to try to use any glue other than welding in this fashion which is easy enough to do.
Extremely messy job. The plastic your adding is instantly traveling to the outside of the triangle because your heating to much n to long. Need to move your triangle over the top on a slight angle. So that just the outer part is totching which way your scraping. And heat gun only totching plastic once heated for 0.5 to 1 second at a time. Here its heated way to much so is hard like spreading pva glue flat. To make much easier n 10x smother n perfectly flat. Heat plastic just untill its as thick as dough or as soft as tooth paste at most. Once placed in crack heat less n less only pushing for a second at a time at lower n lower heat. So plastic is effected less n less and perfectly flat n smooth. Not even needing light sanding if you do a slow great job
Your inside canoe repair looks better than the one outside. Why not start with the metal mesh inside and then go to the outside part just to fill up the gap. the repair would not be that much visible outside. Other than that good job and thank you for your video.
I have that same canoe, only mine is red :) In hindsight, it seems like it would have "looked" better if you'd have done the ugly stuff on the inside and filled in the wide open crack on the outside. Also, i've seen some more expensive plastic welding tools that will have a plastic feeder (Probably cost a lot more though) Great video, love the use of the milk jug! (Now you need to put a trolling motor on it!) I'll be uploading a video of mine soon.
Have you seen the video on RUclips where a guy heats up a putty knife red with a propane torch and then gets a piece of tarp and melts it into the canoe with the putty knife? It's a pretty helpful video. The patch would looks pretty good too.
Good repair job! Thank you very much! You could use help with your canoe paddling form. You're just using your upper body in the paddle stroke. Use more leg and body core muscles. You will be able to paddle further and not get tired so quickly.
Very informative. I like the ideas..Two things though....Wear your PFD (personal flotation device) so you be around to make more cool vids, and solder is pronounced sawder. Thanks for the video.
The worst "repair" ever seen.. Get some PE-Sticks, get a hot-glue gun that can reach 240°C. Chamfer the crack, fill up the whole space with the PE from the Stick with the hot-glue gun and sand the repaired area. The hot PE will melt itself into the PE of the canoe and fills up any remaining spaces. No reinforcement needed.
you don't have a clue at what you're doing there're professional plastic welders of which i am one....first you have to chamfer what is to be welded then get a plastic rod the same grade as what is to be welded.Plastic milk bottles deteriorate in time .The only thing you got wright was to drill a hole at the end of the crack....

It worked, but how about sanding the welding area so that it gets a smooth surface and painting it?
Sanding it is a good idea. Unfortunately, HDPE is very difficult to paint. Maybe one of those paints designed for plastics would work.

Does it ever crack when it flexes
What about sanding it down? Can you sand hdpe?
Bloopers at the end, Nice one! The soldering thingy.
How come you didn't use Waterweld by JB Weld? It sets in an hour and is sandable.
I'm not familiar with Waterweld. It's probably worth looking into though. The problem is that most glues and epoxies don't stick well to HPDE.

Great job! But I cannot find the welder anywhere..... please help...couldn't find on Harbor Freight or Lowe's on-line.
I rode bicycle to Lowe’s after checking online; it’s a Weller with assorted tips.
is there any way of getting paint to stick to that type of plastic i have the same canoe but its orange and i want to change colors this spring
HDPE is very resistant to chemicals including paint, unfortunately.
You can buy sticks in different colors or at least green like this canoe which I also have. Try looking.
Could you sand it down and apply more plastic until you had a somewhat smooth finish?
That might work. The problem is that the plastic shrinks as it cools and in my experience, shrinks in unpredictable ways resulting in a rough finish.
Yes, that's a good idea. I don't know if you'll every get a perfectly smooth joint but with some work you can make it look at least a little nicer.
Wow thanks it was exactly what I was looking for
i have the same canoe and my holes are on the bottom. gonna try this and see if i can get this baby on the water
Good luck!

Milk crates Are made of HDPE Income in green That is identical to the colour the Canoe
Just buy the welding sticks online which are cheap in the color you want like to match this canoe. Why fight with cutting up milk crates, geez.

That's probably a good idea.
after you have finished the job, add a coat or two of flex seal to make it look better.
Flex Seal won't stay stuck to HDPE.
Just use spray paint for plastic after sanding with 220
It's about 3 inch
This model canoe is the only one I use. Put a life vest on pls. I loved the demonstration. Thanks. 😁👍👍

because......ummmmm......i love milk. Really made me laugh
Great Idea
we could just slap some colorful duct tape over the "ugly weld"...
good stuff!
That's what it had on it... You can see the residue on the sides of the crack.
If he used the matching green welding sticks, available cheaply enough, it would not look so ugly.
Thank you :)
Yea.!! I broke the tip of the welder!! hahahaha!!! tks
Mine broke within 30 minutes of use... Friggin Harbor Freight!
Lmao he said big fat tip
Genius!!
good luck
Thumbs up. - Except milk is GROSS!
wow!!

The hot PE will melt itself into the PE of the canoe and fills up any remaining spaces. No reinforcement needed.

you don't have a clue at what you're doing there're professional plastic welders of which i am one....first you have to chamfer what is to be welded then get a plastic rod the same grade as what is to be welded.Plastic milk bottles deteriorate in time .The only thing you got wright was to drill a hole at the end of the crack....
It might not be the best way to do it but the welds have held up for over 4 years and I consider that good enough for my purposes.
Joe Freitas want to know why I don't trust you? Because you can't even spell the word right correctly.
Drill my crack hole, Joe.
Gorilla tape works fine for me
