Hey Everyone,

Just thought i'd through a rave out there for a product.

I have been rocking Fiberfix Flex Patch on a crack on my boat for 4 months and it's holding up great. Highly recommended for throwing in the patch kit for interior side repair.

That's so serendipitous that you post this today! I was actually testing different patch material today! Tyvek tape to be exact. There was a 5" tear all the way through the material on a thwart. I didn't put an inside patch, I just put a single 8" piece over the area. I aired it up to the recommended 3psi and it held with no deformation at the cut. The tape held perfectly. The tear didn't show any signs of the air pressure that was inside.

So I figured...... let's see what this tape can do....... thwarts are cheap enough to replace.....

I put that baby up to 6psi and it held! I was shocked! I couldn't believe that the adhesive held so well! In all honesty, I didn't leave it at that pressure long but the fact that it held at all is impressive.

The tape is still on the thwart at 3psi. I want to see it's long term use/damage/wear. Also the effect, if any, the adhesive has to the material. I'll post updates as the results come back.

I've found that tyvek becomes more or less permanent after a few weeks. Great stuff.

Be sure to install it on a cleaned/prepped surface, and round the corners of the tape so that there's less chance of peeling up over time.

Thank you for the insight into Tyvek. I still need to do my own testing to see the results myself. I also have doubts about it's permanency. In the off season I repair boats and you would not believe some of the things guides use to fix leaks. If I can take an epoxy off of a materials surface well enough to weld to it afterward, Tyvek tape shouldn't be an issue.

I have not used Tyvek tape. Would like to buy a roll. Looked up on Amazon and there are many types. What brand and type tyvek tape do you recommend?

OK, I'm intrigued. What's the back-story?!
Backstory? I love everything outdoors. I've been a trail and raft guide for years. I'm very good to my gear, but I use it, hard. As such I end up fixing broken gear alot. When fixing gear you see how it could be made better so sometimes I make my own. Backpacks, tents, hammocks, different suspension systems for hammocks, tarps, and rain gear are all things I've made for myself.
As a raft guide you become very adept at fixing boats on the fly. My repairs were always a little nicer. I first started really doing it for just my outfitter. Then started bouncing around offering my services to others.
I'm damn good on a sewing machine or with a hot air welder. Basically I'm Mr. Fix it DIY in my circle of friends. They always bring it to me first.

Tyvek sounds awesome, I'm going to look into it for throwing some pieces in the just in case bag. Might be nice for those of us with OC1 friends who're always repairing float bags too.

I'm not recommending any Tyvek tape yet. I'm still testing its durability, "permanence", and if it leaves a residue when removed to do the repair. Most of my time doing repairs is spent cleaning the area first. The repair is actually really fast compared to the cleaning needed to do a repair correctly.
I am not recommending Tyvek at this point. My opinion is still out on it.
If you want to give it a try yourself, on your own liability, it was the clear 1.88" tape.

Clear tyvek (and gorilla) isn't nearly as good as the basic white stuff with blue "tyvek" lettering.

I repaired a cut tube with it ~5 years ago, just a quickie til I could get it home and patch it proper. Or so I told myself.

A few months later when I finally got around to it the tyvek tape had bonded to the boat. Could probably have gotten it off with solvents, but why? Couldn't peel it up with fingernails no matter how persistent I was, so I left it.

And it's still there, still holding perfectly, 5 years later.

FiberFix Flex Tape/Patches are 1 time use per package

i just saw the info on not being able to reuse FiberFix in comments on the FiberFix website. Also, several users were surly about receiving material that was not usable (suspected the packaging had been damaged), so be sure to check the flexibility of your tape/patches when you buy it, protect the packaging from punctures, and use it all at once!


On the Tyvek tape, other reviewers agreed that the white tape with blue lettering was superior and that it can become permanent if not removed for a permanent patch. Alpaca echoes this warning in their repair instructions for their packrafts.

Stay wet my friends!

I think the original post was about patching over a crack in a hard shell kayak...so it definitely doesn't need to be as flexy for that application and is probably why the FiberFix stuff worked well.

For inflatables...its hard to pass up just using Tear Aid, which is the stuff most Rafting Manufacturers recommend and include in the patch kits they provide with the boat (at least my Hysides and Aires do). Tear Aid is great because its stretchy, sticks well, but is still easily removable for when you want to do a real repair once you get home.

The Tyvek stuff is great for general "durable temporary wildnerness repair" though...just might be a bigger pain in the ass to remove later. Talk to a friend that does house construction...they often have a few partial roles left over in their truck after a job.

Totally agreed, with the twist that the tyvek is durable and sticky enough that (unless you don't like the white tape on your boat) it can be left on as a permanent fix.
Mike I wanted to let you know that you were right. That tape hasn't budged! Monday I'm gonna run the welder over it to stimulate being exposed to the sun. I want to see if it leaves a residue when I remove it.

I've used Tyvek Tape to repair cracks in a hard shell kayak with excellent success. In fact I had a Pyranha Ammo that had an 8" crack under the seat. I pulled the seat, drilled out the ends of the crack and filled it with Aquaseal. Then covered both sides of the crack with Gorilla Tape and then put a couple strips of Tyvek Tape over the Gorilla Tape inside the cockpit. That thing was 100% water tight for 2 more full seasons of heavy use before I voluntarily retired it.

Home Depot carries the Tyvek Tape with lettering right next to the Tyvek. Usually at the back of the Building Materials section.
