Home-Made Sugru


Introduction: Home-Made Sugru

About: I am a 19 year old content creator and thb i forgot about this account and left it vacant for a while, and I realized how many views they were getting, so I want to continue to help you guys create, but i wa...

I just came across this awesome and fairly new substance that is called sugru. Sugru is a whole nother class of silicon because it bonds to most materials, and when it sets this stuff is basically indestructible. I didn't really feel like buying this stuff online so i did some searching on line and came across this way make sugru and it was very cheap, in all it probably only cost me $4 to $5 to make around 9 ounces.

Step 1: What You Need

- silicon caulk (you can get this at any home improvement store)
- A paper cup
- A plastic spoon
- Corn starch/corn flour
- Food coloring

Step 2: The Mix

Put the amount of silicon caulk you want into the plastic cup, the mix is 50/50 so you are going to want to put the same amount of corn starch in the cup as you put silicon caulk.  

Step 3:

you can color this any way you want but I used a few drops of food coloring and mixed it thoroughly until it turned the color I want

Step 4: Adding Water

Now time to add a very small amount of water, after you add the water mix it around and dump the excess water out. the mix is going to be a little soggy so add a pinch or so of corn starch and mix it in to the mix. now you should be left with a substance like play-do that you can mold, bend, and twist around.

Note: if your mix is still too sticky to use you can put some corn starch in you hand and start rolling the mix around in your hand.

Step 5: Finished

Now you don't have to go online and get ripped off by the sugru company you can just make your own sugru.

    so has anybody tried this with the acrylic latex caulk shown here? everywhere else insists on silicone 1, which is more expensive & hard to find in smaller squeeze tubes, so would be great if it turns out pure silicone 1 isn't necessary! also curious if rtv silicone works... anybody?

    You say to use silicone caulk but in the picture you show cheapo ALEX sealant which is acrylic latex, very different

    Ive used spray paint successfully too, it just doesn't give as much as a good color.

    This isn't *exactly* the same as the "oogroo" instructable, because that recipe specifies linseed based oil paint for color and this one specifies food coloring.

    The last time I was at Home Depot, I looked in the paint department and could not find any linseed oil based paint - can anyone recommend where to find this, either online or at a national chain (and if so, a specific brand or product)?

    Linseed based paint is usually over with the wood Home Depot has it for around $23/Gal, You can get on home depot.com and order it if your local store doesn't have it. They will ship it to the store for free.

    A little late but you want to go to a craft store or artist supply and get tubes of oil paint.

    I found a begiiners asssotment of paint for maybe $6.

    It may harden like Sugru, but will it rip off like regular sugru does?

    This is basically an uncredited rip of the ooGoo instructable: https://www.instructables.com/id/How-To-Make-Your-Own-Sugru-Substitute/

    When you say 50/50 caulk and cornflour are you talking weight or volume?

    isn't this a copy from another instructable? if so this is a no-no

    Sugru isn't ripping you off. They're saving people time and effort by providing a convenience.

    Perhaps, but the DIY version isn't a quick and easy proposition. In fact, it's kinda messy. I don't use a lot of Sugru, but when I do, it's a last resort and only for small projects. It just isn't cost effective.

    I'm curious about the caulking you used and just need a little clarification before I try this. The brand pictured is actually an acrylic latex caulk with a little bit of silicone in it and can be cleaned up with water. The materials list states silicone caulking that I don't think can have water added to it (it's water repellent for around sinks and such). Please help me understand what you used. Thanks!

    The water bonds with the cornstarch and the acrylic/latex. When the water evaporates, you're left with a mass of material that will eventually harden up as it sets. The starch provides strength while the rest of the mixture make it feel like a hard rubber.
