Sugru - how to make your own DIY sugru sachet / save left over sugru

Featured
When I open a 5g sachet of sugru I tend to use it all but sometimes there is a little piece left and often this is where I get really creative, thinking of what to do with the leftover piece.... :)

...some people like to save their left over sugru for later but as sugru is a moisture cure material, it is very difficult to stop it from curing :(

This is a simple and easy to do project to help you save your left over sugru for later :)

N.B. your DIY sachet should save your sugru for a while but will not as good as the original sachet

The sachets that your sugru is packaged in is not ideal to use for DIY sachets as there is a residue of sugru there that does not allow for a good seal :( The pouch material is clean which makes it ideal for the job.

Step 1: Use your sugru pouch

To make your DIY sugru sachets, you can reuse your sugru pouch for it's moisture barrier foil.

You can make 4 good sized sachets from the Smart Hacks Super Pack and 4 smaller sachets from the Smart Hacks Pack :)

Hello, just reporting back regarding the hot knife sealing technique, i am still a computer luddite and cant send a photo of my botch job.
Anyway my son was playing football in his room and broke his light so i got out the last pack of sugru the one i had sealed with the knife, it still felt squidgy so i opened it and it was as good as gold as soft as before, i bought the pack at christmas and the used by date was october i had been keeping it in the fridge also. so all is well, cheers sugru.

hello, i just opened a pack and did not need it all, so i used your steps, but i don't have an iron, so i heated up a knife and it seems to have worked, i used a tea towel so i wouldnt burn me self when pressing on packet, still soft a night later, shall report back soon, cheers for the heads up
projectsugru (author)  cuttyranks1 year ago
that's interesting, can you post a picture of your pack ? Look forward to hear how long this lasts.
i am having trouble replying, as i am not very computer literate, i cant even upload a picture, i have had another look though and i left to much air in as i didnt really take very much care with it, just thought i would try, but its still soft, sorry if you are receiving multiple replys from me.after tectsro
How long did it last in the DIY sachet?
projectsugru (author)  Adambowker981 year ago
Hi, I tested this for about 2 weeks and it was still good, it really depends on the quality of the seal you create but I would recommend about 2 weeks.
thanks!
You know if you open one side of the 5g sachet you can reseal it with those food bag sealers really easily, it'll be a better seal than folding alone plus no need for chopping up, I can attest to it working for a few days.
You could add silica gel in the bag! so as to remove moisture in the bag! because food bags generally are quite big!
That would do exactly what you want to avoid. I'd prefer not doing anything counter-productive, thanks :)
Why would it be counter-productive? isnt the idea to remove mositure? :S
No: If I'm not mistaken the whole idea is to keep the moisture in, to keep it from drying out. But maybe that's not true...
It says that sugru cures with moisture... and since the air is moist sugru cures in air...at room temp. therefore you would want to remove any moisture from the package!
Please, please.......All of you - try to use proper grammar. I would greatly appreciate it, since this is one of the few websites I allow my teens to view. Former Prof. Thank you.
Were we not?

hi timothymh and shanmugammpl, just to answer both your questions. sugru is a moisture cure material, the moisture in the air reacts with sugru to make it cure so the purpose of the sachet is to keep the moisture out. On the other hand, the volume of air that gets locked inside a sachet is negligible, so there is no need for silica gel. Hope this helps :)

Oh. *shrug* Shows how much I know. xD

Hi Killerjackalope, interesting idea, must try it out, thanks :)

James
I actually tkoo one of them apart in another sugru project
projectsugru (author)  killerjackalope3 years ago
hey killerjackalope, just took a look at your project, very cool :)
James
Thanks, as for the comment on the wineglass one, so far moisturizer, fiber putty - the hair gel and olive oil have all worked great as a way to stop your hands sticking to it.

Hey y'all. Use a bit of parchment paper (from the baking section of the grocery store) between your iron and any plastic you're trying to weld. Should help avoid icky situations.

I really thought it was a condom at first....very comical - how to reseal your condom? But no, this is definitely useful and now I really would like to try some of this stuff on my tools for work!

I have read about making your own faux Sugru from silicone caulk and corn starch, I must try this sometime...
evilution3 years ago
I find that it's very easy to separate into 2 or 4 pieces whilst it's still inside the sealed packet, then I stick the packet in my cheap eBay heat sealing machine.
Make separate compartments for each piece and use them as you see fit.
projectsugru (author)  evilution3 years ago
Hi evilution, sounds interesting. Do you reseal an unopened sachet into 2 or 4 mini sachets before opening it ?...

James
projectsugru (author)  projectsugru3 years ago
If this is the case, there is a very strong chance that there will be sugru in your seals. Moisture will travel through the sugru and cure the sugru within the sachet :( However, a cheap heat sealer is perfect to make your own sachets from the pouch which eliminates the risk of getting sugru in your seals :)
Well technically you can't reseal a packet that hasn't been opened but I wouldn't want to appear pedantic lol.

Yes, I partition the sachet before opening and it seems to have preserved the unopened blobs perfectly. You can always do 2 seals right next to each other just in case if you wanted.
projectsugru (author)  evilution3 years ago
cool, very interesting, I am going to try this one out myself. Never thought of it before :)

I don't mean to sound too uninformed. What is sugru? A sentence or two explaining what it is would be helpful then, go into the instructable.
projectsugru (author)  Foxtrot703 years ago
Hi Foxtrot70 - the very best way to discover sugru is at sugru.com :) Watch thr video on the home page, check out the gallery and then take a look at the blog :)

James
Hi James - I just viewed the sugru website. Very interesting, I see this could be used as a really quick mould compound for a quick one-off item. Thanks for the reply and the link.

were can i buy it?
projectsugru (author)  ducktape1003 years ago
Hi ryderfitzpatrick - you can buy sugru at www.sugru.com :)
James
thank you

Massive kudos to you guys for publishing this. Most companies selling perishable products wouldn't want their consumers to know this kind of trick for fear of them not buying as much of it. If anything, knowing I can do this would make me open a packet sooner rather than waiting around for several fixes to do.
projectsugru (author)  Jayefuu3 years ago
Hi Jayefuu, thanks :)
James
Agreed. I've been looking for something to do heat seals like that for a while, but haven't thought of anything quite so simple (though a rig with the heating element out of a toner printer would be cool).
skimmo3 years ago
that,s pretty damn savy, do you think it will work for mi goreng flavour packets?
projectsugru (author)  skimmo3 years ago
Hi skimmo, yeah, it should, but the trick will be to find the correct temp on your iron for welding the plastic they use for Mi Goreng package. Too hot and it will stick to your iron and make a mess, too cold and it just won't weld :) Definitely worth testing though, perhaps worth a dedicated Instructable ?......
James
I'm on this website for a while now, and I've seen several ideas already, how to use Sugru. And I love them.
But...What is it!?
What is the material?
What's it made from?
Is it clay? Is it plastic?
Is it sticky? I think you have several colours Sugru, isn't it?
I'm asking, because we might have an alternative in The Netherlands I can use. Just (very) curious.
It is like a clay first, and after a while it hardens to a silicone stuff. You can stick it to something, and it won't come of, but after it hardens, it isn't sticky anymore. It's patented and pretty know so I don't think you'll find anything like this. But it's from England and the shipping is really cheap. So just buy some on sugru.com
Thank you very much for answering, Mister-B. :)

haha, I glanced over at the picture when scrolling, thought it was something dirty! xD Very nice idea, too bad i cant get sugru in South Africa... :(
projectsugru (author)  Spydamonky3 years ago
Hi DemonSpawn, we ship to South Africa :) handling + shipping costs just 11.05 ZAR

James
Thats Awesome!! how long would it take to get here though, because judging by my other parts ordered from America, I'd be better off walking there to fetch them! :D
projectsugru (author)  Spydamonky3 years ago
HI DemonSpawn, actually, it takes quite some time to get through customs in South Africa, it should take 5-10 working days but realistically it takes about 3 weeks or so :( If you order some you will need to be a little patient.

James
Ahhhhhh. I wish I had known about this sooner! A fair bit got wasted. :( Oh well.

Any idea how long a well-sealed DIY sachet will keep the Sugru fresh for?

Does it depend at all on how long the Sugru was exposed before re-sealing?

projectsugru (author)  Kiteman3 years ago
Hi Kiteman,

I have a sachet here that I prepared yesterday and one from today, I will monitor them and report when I see signs of curing in the sachet.

Watch this space :)

Exposure to moisture before re-sealing is not a real problem, once sealed up, it should stay stable. So as long as the sugru you re-pack still feels soft you should be fine.

You thinking of giving this a go ?

James

Just keeping it my mind, should I need to.

I've never had any spare from a sachet yet.
