Sug-what? Pronounced seew-grew, this sticky substance is like moldable glue that's clay-like out of the package, then hardens to rubber after 24 hours. People have found all sorts of ways to fix and create things with this flexible, interesting stuff. But perhaps most intriguing is its potential for renters. Because Sugru adheres to most substances — like ceramic tile, wood, and plastic — but can also be easily removed, it's potentially a way to hang items temporarily without using nails or drilling.
Sounds revolutionary right? We put it to the test to find out just how fantastic Sugru is.
One of Sugru's Home Hacks Kits costs $15 and comes with four single-use packs of this moldable, sticky substance: in classic red, snow white, black, and silver grey.

Project 1: Paper Towel Holder
I ordered this paper towel rack for the kitchen. It technically required screws for installation, but was super easy to hack with Sugru. I placed three large pieces along the backside of the mounting hardware, pushed them up through the screw holes, and then flattened them over the surface once the hardware was stuck to the wall.
Color used: Black
Dry time: 24 hours
Strength: Super strong. This was a legit hold and the paper towel roll wasn't going anywhere!
Removability: Difficult, but it eventually popped off when I used a screwdriver.
Did it leave a stain? Left the tiniest bit of residue behind.
Conclusion: Key to this test was using as much Sugru as I possibly could. It also worked well with the towel holder's mounting hardware.
Project 2: Kitchen Rail With S-Hooks
I ordered this rail, which came with two tiny hardware inserts as the mounting hardware. To install the rail, you ordinarily screw those pieces into the wall, then place the two end knobs over the mounting pieces, tightening a tiny screw until the rail fits snugly over the mounting hardware.
The photo above shows the original piece of mounting hardware (with the white Sugru still inside) that you screw into the wall.
I struggled with this and wound up trying to mount this rail twice.
For the first test, I used the same method as the paper towel holder above. I placed Sugru on the backside of the mounting hardware, pushed them up through the front, and then flattened them over the surface once the hardware was stuck to the wall.
Color used: White
Moldability: The Sugru was, as always, easy to mold, but difficult to fit through the tiny hardware pieces.
Dry Time: 24 hours
Strength: I wiggled the actual hardware before mounting the rest of the rack and everything felt nice and secure. But once I installed the rack, tightened the screws, and began to hang utensils, I only got about three on the rack before it all popped off the wall in a very dramatic fashion.
Removability: Way too easy. I used such a small amount of the compound the rail just popped itself off the wall.
Did it leave a stain? The white Sugru left zero stain.
Conclusion: I'm not 100 percent sure what happened with Test A. But my best guess is that, because the mounting hardware was so small, I could only use a little bit of Sugru.
For my second attempt, I didn't use the actual hardware and, instead, tried making molds of the mounting hardware completely out of Sugru.
Color used: Red
Moldability: I used a new pack of Sugru and it was easy to get close to the shape I needed. I kept testing the end caps over the mold as I went along, so I was able to get close to an exact fit.
Dry time: 24 hours
Strength: I couldn't get a proper hold. I used about a nickel-sized chunk of Sugru for both pieces, but the molded mounts were just too flexible. The tiny screw that you use to secure the rail over the mounting hardware just kept pressing into the flexible Sugru, so it never had a chance to get a good grip. The pieces popped off the wall, but they weren't solid enough to hang the rail securely.
Removability: Pried them off with a butter knife, then scraped the rest of the residue with my thumbnail.
Stainability: The red Sugru left a stain on the wainscoting. Originally I had saved the white Sugru for this test but it didn't work and I was left with red. I'll definitely need to paint over this before I move out!
Conclusion: This hack was 100 percent unsuccessful for the reasons stated above.
- I highly recommend using a coordinating color for your wall if you plan to eventually remove whatever it is that you're using Sugru to hang, as it will more than likely leave some colored residue behind.
- Don't trust it on things that weigh more than a small stack of hardback books. And when you use Sugru, use a lot!
- It's all about the hardware. When picking out your shelves or storage pieces, research what each piece of hardware looks like. The key to using Sugru is being able to get a good bond on each side of the hardware — a Sugru sandwich of sorts.
- The 24-hour dry time makes it less than convenient to use for a quick-fix situation, but it's good to use on something that you don't need to use right away.
- Keep in mind when tossing Sugru in your tool kit that there is a shelf life on the product. Each packet has a "use by" date on the back, and the shelf life can be elongated by storing it in the refrigerator.
Sugru is a really cool product, but you have to find the right context for it to work. Asking it to support too much weight, or not providing enough surface area for it to bond might render it useless. But there are plenty of places where it's great. I love the idea of using it to save phone cords, to add feet to the bottom of a planter or speaker, or fix tiny parts on appliances, like the dishwasher rack. There are many ways to use Sugru at home.
