CHOKING HAZARD -- Small parts. Not for children under 3 yrs.

Product Description

Color: Multi Color

sugru is the exciting new self-setting rubber that can be formed by hand. It moulds like play-dough, bonds to almost anything and turns into a strong, flexible silicone rubber overnight. Developed by a team of product designers and material scientists, sugru's patented technology is unique in its combination of hand-formability, self-adhesion and flexibility when cured. It feels like modelling clay, and it's that easy to use too. Once cured, its durable properties mean it's comfortable in extreme environments from the dishwasher to the ocean in Antarctica. sugru helps athletes and outdoor types repairing leaking hiking boots, customise olympic fencing foils, and patch up punctures in camping mats or Gore-Tex rain gear, amongst other things.

Length: 2:51 Mins
I love this stuff! It has the consistency of Play-Doh when you open the packets and is easily molded into shapes and sticks to most materials. It's great for fixing things that I wasn't able to fix before and to make some other things more user friendly. It seems expensive but the repair on my vacuum alone would have cost more than the whole package if that part was even available. A multi color 8 pack came with eight 5 gram packets. There were 2 red, 2 blue, 2 yellow, 1 white and 1 black. The product is waterproof, UV resistant, electrically insulating and dishwasher proof when cured. Curing takes 24 hours. But it starts to harden after about half an hour. I was still able to make some changes on one of my projects over an hour later but it was noticeably firmer. When cured it will withstand temperatures of -58 degrees F to 356 F. When it's cured it has the bendability similar to an electrical cord. The thicker it is, the less bendable it becomes. It seems pretty strong, especially a thick piece.

I'm adding a video showing these things that I used it with:

I repaired the cord holder on a vacuum cleaner that had broken off. It works great now, better than the original. I used 1 packet of red for this.

I added some to a plug of a air popper that didn't have an on/off switch and had to be unplugged to turn off. Now it's easier to grab hold of and the shape of my Sugru-thingy makes it easy to wrap the cord when putting it away. The adaptor took 1 packet of yellow.

I used 1 packet of yellow mixed with about a tenth of a packet of black to make sort of a brownish color to stick some leaves back on a silk tree. I had tried glue guns and florist wire previously and neither would stay on because some of the little nubs that hold the branches had broken off.

I've known about Sugru for a while, but didn't have an application for it until recently. The band from my Suunto watch broke and I could either try to repair it or purchase a new Suunto strap and band set (the smaller band is not sold separately). Since Sugru was cheaper than a new Suunto strap, I tried it out.

I wrapped Sugru around the original band and gave it 24 hours to cure. It worked well, and I haven't had any problems with it since then. Even though the band is still broken, the Sugru attached to it and holds the band in place over the strap.

I would recommend Sugru for many different kinds of repairs, but it's not perfect. Here is my opinion on Sugru's strengths and weaknesses.


* Easy to work with
* Strong and long lasting
* Lots of applications
* Comes in various colors


* Short shelf-life. Depending on how you store it, Sugru will be usable for around 6 months sealed in its package. This makes it difficult to buy the right amount of Sugru for your application. Since repairing my watch, I searched for other things to repair. While I found a few others, I don't know if I will end up using all of it, which means it will go to waste.
* Can't save leftover Sugru. Once you open a package, you have to use all the Sugru.
* Expensive. This is especially true if you end up wasting some of the Sugru for lack of projects.
* Stiffer than you might think. Many of the suggested uses imply that you can add Sugru to handles and knobs to provide cushioning. However, cured Sugru is rather hard and has little give. That makes is good for some situations (repair a watch band), but not so great for others (cushion the inside of a scissor handle).
* Heavier than you might think.

Initially I bought this to fix a few vinyl/plastic model figures that were purchased from a yard sale. One of my friends introduced me to this product and well, I was skeptical at first. But, this thing really does what it says. It does bond very well and cures well on almost everything I've tried it on so far (I've plugged leaks, made rubber grips on some plastic tools and various other things).

For someone using this product for the first time, I definitely recommend reading thru the instructions then going to their website and watching a few videos. But it is very simple. Remove from packaging, roll it around your hands and you can mold/meld it to whatever shape your heart desires and it'll stick to almost everything. After curing, it does leave a bit of the rubber feel (slightly soft rubbery feel) so if that is what you want this would work great. You could also use a gently water/soap solution to smooth out the rubber prior to letting it cure for a smoother feel/appearance. With that said, I'll leave the rest of the review as a list of pro's and concerns I had with this product. It is, overall, a very nice and innovative product and would fit most users quite well I imagine.

+About a 6 month use by date
+Steep price for small amount of product
+Sticks on hands even after wiping with a paper napkin / towel and washing
+About 30 minutes to use it before it starts curing once you open the individual wrapped packet

+Attaches to almost anything
+Easy to work with
+Cures as advertised
+Can mix colors to create almost any color tone you need
+Can smooth it before curing by using water+soap
