After having sugru bumpers on my iPhone for a year I learned just how protective they are...
so I made this video to show you just how much I trust them !!!

This is the original video which shows how to make sugru bumpers and how to remove them.

Step 1: Get Ready

Picture of Get Ready

To get started, make sure your hands and your phone are clean

If you don't have any sugru, you can buy it from

Step 2: Open Sugru

A Smart Hack (5g) sachet of sugru is plenty for this hack - once you open the sachet you have about 30 minutes to work with sugru before it starts to cure so take your time - work the material in your hands for a few seconds, this makes it work better

Step 3: 4 Corners = 4 Pieces of Sugru

Picture of 4 Corners = 4 Pieces of Sugru

Tear the sugru into 4 even pieces, one for each corner of your phone.
Press a piece of sugru onto each corner (be careful not to cover the buttons, speakers or camera lens) - then fold the sugru over onto the glass on the front and back of the phone.

Step 4: Get the Shape Right for You

Once the sugru is in place, get the shape right - gently touch the sugru repeatedly to tweak the shape, don't panic, you have plenty of time.

Step 5: Leave Sugru Cure

Once you are happy with you hack, leave it somewhere to cure overnight - sugru cures to a lovely silicone rubber

Step 6: OK - But Does Sugru Come Off?

Yes, sugru is removable - carefully tear the sugru from your phone

Step 7: Wipe It Clean

There will be some residue left behind, to clean this off, simply scrape it with the back of your finger nail then wipe it clean with a cloth.

Step 8: Good to Know:

sugru bonds well to the metal on the frame of the iPhone 4 but does not bond to the glass (there is some funny coating there)
sugru does bond to previous iPhone screens!

yup, can't see why not :)

dinhoconrad (author)2012-11-12

Can I do this in Galaxy S3?

xxcalebbxx (author)2012-10-10

I'm thinking about getting some Sugru for my motorola flip phone...btw, can I get Sugru in the USA?

projectsugru (author)xxcalebbxx2012-10-18

hi, yes, you can buy sugru directly from us at, we ship from Michigan so it should get to you in about 2-3 days :)

DoctorDv (author)2012-08-31

After you remove it, can you put it back on the iPhone and use them again? Also, will these work on an iPod touch?


projectsugru (author)DoctorDv2012-08-31

Hi David, once you remove the bumpers, you will not be able to put them back on :( they do work a treat on an iPod touch :)

DoctorDv (author)projectsugru2012-08-31

Thanks! I really think sugru is interesting and I can't wait to try some of it out on the instructable I am currently working on. I'll shoot you a message so you can check it out.


timweaver17 (author)2012-08-14

does anybody have experience using sugru on an ipad?

projectsugru (author)timweaver172012-08-14

yes, we put sugru on our iPad here (removed it as well so no picture to show at the moment) we plan to post a project soon that uses sugru on an iPad though. Works a treat and is removable too :) You thinking about putting bumpers on yours ? A customer has put sugru bumpers on their iPad, check it out here.

timweaver17 (author)projectsugru2012-08-14

i am thinking of bumpers on mine, yes.

Audiyoda (author)2011-05-22

Interesting that in 85 comments no one has mentioned there's a Instructable to make your own sugru - on the cheap.

dtoney1 (author)Audiyoda2012-08-02

I don't agree with you any more...

CropJ (author)Audiyoda2012-02-11

I was excited to read all this and on top of it you left me the pleasure of typing in all those letters to search for it myself... I thought I would help out the next drifter.


Irock148 (author)2012-01-31

If you made an X connecting them you can make a removable thing and have even more protection

ace1423 (author)2011-10-22

i like it but can you drop it from about 4 feet

projectsugru (author)ace14232011-10-23

yup, I have at least :)

Chowmix12 (author)2011-09-16

Can you put the bumpers back on after you take it off?

projectsugru (author)Chowmix122011-09-17

hi Chowmix12,

once you remove the bumpers you can't put them back on.

You can easily create a new set from fresh sugru, or, if you remove the original bumpers carefully, you can use much less sugru to mount them back onto your phone.

I hope this helps.

zolracal (author)2011-05-22

I'm from mexico... i have not idea of where i can buy it ...
could be better if you say how to make it

NewYorkRob (author)2011-05-22

I personally prefer using 4 mini tennis balls. You simply cut a slit in each and slide the mini-tennis balls onto each corner of the iPhone... or any similar phone.

projectsugru (author)NewYorkRob2011-05-22

sounds awesome :) you got a picture ?...

mman1506 (author)2010-08-20

does sugru remain a slightly soft and bouncy exterior after drie or does it become dried and hard

projectsugru (author)mman15062011-02-07

hi mman1506, sorry for not replying to this before :(
yes, sugru remains soft and bouncy once it cures :)


The cats meow! (author)mman15062010-11-14

I'm sorry for commenting on your post mman1506 but my iPod won't let me leave my own comment :/ and our pc is broken ATM with a Trojan horse virus so I'm forced to use my iPod touch :( anyway I was wondering if you could still use sugru with a iPod or iPhone case but stick it onthe outside of it because I really like my case and it's helped alot but I still get a massive crack down my screen which I've replaced 3 times now! :( I really would like to know. Thanks :) and sorry again mman1506 for commenting on your post without answering your question.

hey, that should totally work, (although sugru does not stick to all plastics) Here is one from Matthew, he had a similar problem to you and when he was fixing the crack, he got carried away, it looks totally awesome... James

Okay thank you :) I've got this cool Case I found of eBay called devil case and I was so happy when I found this but just remembered that I had the case so now in happy that it will hopefully stick

projectsugru (author)mman15062010-08-21

hell mman1506, sugru cures to a soft and bouncy silicone rubber :)

Blue Mist (author)2010-12-16

I have a problem mixed with a question.... I really want some sugru as it does seem to be a great substance or item whatever you wanna call it...... the problem is I live in the UK and i can't find anywhere that sells sugru, is there anyway of getting it in the UK?

projectsugru (author)Blue Mist2011-02-07

Hi paladin97, just noticed this question. We sell sugru in a small number of shops in the UK. In London you can buy sugru at:
The Design Musuem -
Tiranti's -
Mar Mar -

and outside London at Snow Home -

Of course, you can buy sugru from us directly at

Hope this helps :)

NatNoBrains (author)Blue Mist2011-01-02

It is a UK company and it ships from London, just go to!

projectsugru (author)Blue Mist2010-12-16

Hi paladin97, we ship from the UK so it's super easy get it. You can buy it from :)

pismoian (author)2011-01-29

Does sugru only bond to iphones? what about an original droid?

projectsugru (author)pismoian2011-01-31

Hi pismoian, sugru bonds to all kinds of matials; glass, wood, metal, fabrics and some plastics :) Have a look at our gallery to get a better idea -

baileygrib (author)projectsugru2011-02-02

Hello! I was wondering if one can surge go on fabrics?? And two, does this work on roundish phones too??? Pease answer asap :) thank you

NatNoBrains (author)2011-01-02

I'm soooooo buying this!

Opcom (author)2010-12-16

that stuff seems versatile. I wonder if a weird scary halloween mask could be made with it.

thatskindacool (author)2010-12-07

Does the Sugru come off often when taking the phone out of your pocket? I feel like this might be a slight problem :(

hello thatskindacool, I have had this on my iPhone for several months and it's holding up great. No problems at all :)

I guess I might have to buy some more for my iPhone then :D

delta1998 (author)2010-06-26

would you that 3 packets of the stuff will cover a whole iphone? if not, how many will?

projectsugru (author)delta19982010-06-28

Hi delta1998, I imagine that 1 sachet would cover the sides of the iPhone considering that you wouldn't want to cover buttons etc. but if you wanted to create the bumpers as well you would probably need a second sachet.

scottfar (author)projectsugru2010-10-18

If the make the 30 dock out hole too small and tight like with the Bumper it makes it impossible to dock your iPhone with it on. I just bought a dock extender that I love from so I don't have to take off the bumper to dock.  good stuff!  Opens things up to addition tight docks like the OtterBox

prosilire (author)2010-07-01

Has anyone tried this with screen protectors? Would you recommend placing screen protectors first and then Sugru over them (maybe a better bonding surface?) OR would you mold the Sugru and then custom-cut screen protectors to fit around the Sugru?

projectsugru (author)prosilire2010-07-03

Hi prosilire, yup, you'll be pleased to know that this has been tried. sugru did not bond to the screen protector on Kary's first generation iPhone. Not sure what brand the protector was but I am guessing that they are all pretty much the same... I would recommend placing your screen protector first and then sugru over that, it worked a treat for Karys :) James

prosilire (author)projectsugru2010-09-02

I LOVE THIS HACK! I molded it over front & back screen protecters to which the Sugru bonded nicely I've had blue sugru on my iPhone 4 corners for a month now. They are still on tight! BENEFITS: 1) I get many comments from people about how cool they look. I should sell the stuff! 2) The sugru corners give my fingers leverage when holding the phone. Hard to describe, but the minimal amount of Sugru goes a long way to keep the phone confidently in hand. 3) Protection. Despite comment 2 above, I fumbled and DROPPED MY PHONE TWICE today, once onto wood and once onto a metal grate. The phone actually BOUNCED and emerged unscathed!! Thanks for this amazing Instructable!

projectsugru (author)prosilire2010-09-02

WOW, that's fantastic feedback, delighted that you enjoyed the Instructable and are having such a positive sugru experience :) Have you thought of adding images of your hack here for others to see ?

nickodemus (author)2010-06-25

This is a great idea!! Has it taken any serious falls yet?

projectsugru (author)nickodemus2010-06-25

Thanks nickodemus, no, I haven't dropped too far yet, but I'm sure it will. I had the same hack on my iPhone 3G, that worked brilliant and took quite a bit of abuse.

nickodemus (author)projectsugru2010-06-25

If it worked well on your old one, the same should ring true for the new one. Thanks!
