FiberFix aims to make duct tape look pathetic

People may make jokes about how duct tape can be used to fix just about anything, but a new product is claimed to be 100 times stronger than our matte-silver friend. It's called FiberFix, and it's a tape impregnated with a resin that reportedly "hardens like steel."

To use FiberFix, you just immerse a length of it in water, wrap that wet tape around the broken item in question, and allow it to set. Although it takes 24 hours to cure completely, it should begin to harden within just a few minutes, and will set to its hard consistency within about 10 – so you need to work with it quickly. Once set, it can be sanded or painted, and will be completely waterproof.

While it's apparently non-toxic, its makers warn against getting the resin on skin, clothes, tools or other places where you don't want it, as it will be very difficult to remove once it's set ... they also advise against using it to make an arm cast, in case you were wondering.

FiberFix isn't the only "instant fiberglass"-like product to ever exist, although a company representative tells us that its high tensile strength, impact resistance and waterproofing qualities set it apart.

Unlike duct tape, it's sold in individual lengths, all of which must be used at once – water vapor in the air will cause unused portions to harden, once the packaging has been unsealed. Prices range from US$5.99 for a 1 x 40-inch (2.5 x 102 cm) strip, to $9.99 for a 4 x 60 inch (10 x 152 cm) piece.

The video below shows how the product is intended to be used.

Nope....it is not fix now product, it may be tougher tomorrow, but duck fixes it now.


Sounds useful! I want some. I wonder if it comes in sheets that could be worked into a mold or draped over a pattern?


I would take this over duct tape any day. However the manufacturer has to come out with smaller package size if it has to be used up in its entirety. Duct tape may work NOW but it won't tomorrow if the ambient temp rises and the adhesive literally melts and the tape drifts! This I can vouch for from first hand experience.


I can see people getting into a lot of trouble with this.

FiberFix is an interesting product but not an "innovative" one. There are many companies that manufacture and market this type of product to repair "almost anything".

The product is widely used to repair pipes in oil refineries, chemical plants, power plants as well as high pressure gas lines. It is also available from such distributors as McMaster Carr and Grainger.

There are variants of this material that cure in as fast a 10 minutes making it a now fix.


sorry - I prefer to have the ability to undo something if I got it wrong ! You would have to go to the ER if this got in the wrong place - just like super-glue - more trouble than it's worth. If you are anything like me, duct tape is everywhere in the house - great stuff, and you remove it fairly easily - I keep several colors for different purposes !

This is stupid, nothing like duct tape, too much money, try again!

Steady there Eddies, they're not REPLACING duct tape with this. This is another product. You may use either, or both, or neither. You know we'll just add water straight to the pouch. Now give some to a Dakar Rally team and there's your advertising :D

Craig Jennings

I'd still vote for duct tape even if this FibreFix came in smaller packets - duct tape is flexible so absorbs stress in repairs. Google "The Mythbusters" to see just how versatile it is ... imagine making a suspension bridge or boat out of the other stuff, would cost 100K bucks!

The Skud

Stuff like this usually has a shelf life of around 6months, so it's basically useless. You'd only keep it for emergencies, by which time it's self-hardened in it's packet already...


And this "Unlike duct tape, it's sold in individual lengths, all of which must be used at once – water vapor in the air will cause unused portions to harden, once the packaging has been unsealed" is why this tape will not catch on like duck (intentional) tape.

The utilituy of duck tape is that I can store it unwrapped and ready to use one handed while lying under some big honking vehicle. This tape doesnt seem like it would fit the bill.

It sounds really good for specific planned uses. Nut ad hoc probably not.

Daniel Harbin

If this stuff sticks to duct tape one could use the duct tape to get the job the way you want it and then use the FiberFix to harden it and prevent it from coming undone. On a side note, I wonder if this would mummify a buffalo.

Well, I have fiberglass sitting around in 2" , 4" , and 6" widths, and a few ounces of 45 minute epoxy resin. So when I get around to fixing that broken shovel handle, I'll use the Fiberglass I have on-hand.

But it's nice to know, and I may tell a friend, or someone who lacks the knack for regular fiberglass ; about this product.

James Donohue

I don't like the price or the "use it or lose it" once opened. Why can't I repackage it in an air tight container?

I would only buy this as needed. But I like the option.

Don Duncan

This is actually very good. I might opt for it when the need arises.


hmmmm.... dip in water and product is activated. Sounds like polyurethane.

$7-$8 in most stores.

But if you want to do it the old fashion way. Take nylon string and wrap it like they show in video. Takes a long time as nylon is very narrow. But with constant pulling as you wrap it, it ends up very strong. then coat with some leftover polyurethane finish you have sitting around, or even glue, though you may have to thin the glue. Have done it on shovels, rakes, handles of wheel barrows. All have lasted for years. Makes for great gripping. Tucking the ends of the string underneath isn't hard, just hard to explain. Start with 1"-2" vertical and wrap over it, last bit you have to keep 4-5 loops loose and thread string under it and tighten.


I think I will just go buy a new spade and learn from the mistake I made breaking the first one. Lets fface it, you gotta be a mule head breaking a good spade in the first place


does anyone know if this will work well to repair a small 1/4" tear on a hydraulic hose? I have a 2mm hose that can't be repaired with duct tape since it holds an oil. Probably the ONE thing duct tape can't fix. So I need something that can stand up to high pressure and oil.
