Sugru SMLT8 Hardware Sealer

What is sugru?

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.

Why is the multi-color pack right for me?

The sugru - Multi Color (Pack of 8) gives you 8 foil-wrapped pieces of sugru ready for 8 fixing sessions around the house, car, garden, kid’s playroom or just about anywhere really. You get 2 pieces of red, yellow and blue sugru, and one each of black and white - perfect to colour blend for invisible fixes around the home, or adding colourful improvements to personal items.

sugru is easily moulded and smoothed with your fingers

How do I use sugru?

sugru can be mixed together to make any colour you like! sugru is hand formable and can be moulded and shaped by hand for up to 30 minutes once it has been removed from its air-tight packaging. sugru sticks to almost anything - in fact it was designed to stick to as many other materials as possible. It forms a strong bond to aluminium, steel, ceramics, glass, wood and other materials including some plastics like perspex and ABS and rubbers like silicone and butyl rubber. sugru feels like modelling clay when you take it from its pack but once it's exposed to air, it cures to a tough flexible silicone overnight. Working time = 30 mins. Cure time = 24hrs (0.2 inch deep).

What can I use sugru for?

When sugru cures, it's flexible rather than rigid which means that you can repair things that need to be able to move like textiles, cables, or shoes. It's also electrically insulating - how awesome is that? sugru is strong and durable and is great outdoors. Once cured, it will stand up to anything the weather throws at it, wet or dry, hot or cold, it will survive. It also won't fade in the sun and it's fine with sea water too. As sugru is a silicone rubber, it feels soft to touch when it has cured, but is also grippy. This makes it perfect for handles and grips as it is comfortable but non-slip. sugru is also stable in extreme temperatures - as low as -58°F and as high as +356°C. It gets hot and cold to touch but it won't get softer or harder or melt.

But will my sugru fixes last?

Yes, they will! Once it's cured, sugru is pretty much like other silicones - so it's completely waterproof. It's easy to clean with soap and water, and it's durable in the harsh conditions of your washing machine and dishwasher, and even in the sea.

use a sharp knife and then your fingers to remove sugru
View larger
But can I remove it?

Yes, you can! sugru can be removed from non-porous materials by cutting it off with a sharp knife and removing any residue with fingernails and a tissue. Easy peasy!

Is there anything else I should know?

sugru is chemically inactive once cured, but people can be allergic to anything so we have to tell you to be careful. sugru isn't certified as food safe or child safe yet. We're working on it, but for now please resist the urge to eat it and don't let your little kids play with it.

sugru has a use by date, you'll find it here
View larger
And one last thing...

sugru has a use by date printed on every individual minipack. If you use your sugru within its date, your fixes will last and last. But if your unopened minipacks in keep it in the fridge you can triple sugru's shelf life!

Color: Multi Color Vine Customer Review of Free Product ( What's this? )
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.

Color: Black
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

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.
