Sugru is the world’s first mouldable glue that turns into rubber.

It all started with an idea and a small team of product designers and material scientists here in London. Our dream is to make fixing, modifying and making things easy and fun for anyone, and Sugru is our solution.

Our patented silicone technology is unique. Out of the pack, Sugru feels like play-dough, and it's that easy to use too. It bonds to almost any other material and cures just by exposing it to air. Its durable cured properties mean it'll stay strong and securely bonded anywhere from the freezer to a steamy hot shower, from the home to the great outdoors.

  • Stick it

    Sugru: Stick it

    Sugru sticks permanently to lots of stuff like ceramics, glass, metal, wood, and most plastics and fabrics. That's exciting because it makes it very versatile, but also you can also use Sugru to bond unusual combinations of materials together.

  • Shape it

    Sugru: Shape it

    It's time to build, seal, fix, create, and stick things together. You have 30 minutes to get the job done.

  • Turns into rubber!

    Sugru: Turns into rubber!

    Give it 24 hours. Sugru turns into a durable, flexible silicone rubber that stays stuck (unless you remove it). Allow longer for pieces that are more than 3-5mm thick. Top tip: to speed up cure time place your project somewhere warm to cure.

  • Strong + durable = great outdoors

    Sugru: Strong + durable = great outdoors

    Sugru is strong and durable. Once cured, it will also stand up to anything the weather throws at it, wet or dry, hot or cold - it will be great. It also won't fade in the sun and it's fine with sea water too!

  • Flexible when cured

    Sugru: Flexible when cured

    When Sugru cures, it's flexible rather than rigid. Which means that you can use it on things that need to be able to move like textiles, cables, or shoes. It's also electrically insulating* - how awesome is that? *Be careful with electricity – stick to small consumer electronics repairs below 24 volts.

  • Soft touch & grippy

    Sugru: Soft touch & grippy

    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.

  • Stable at high and low temperatures

    Sugru: Stable at high and low temperatures

    Sugru is resistant from -50°C (-58°F) to +180°C (356°F). It gets hot and cold but it won't get softer or harder or melt.

  • Waterproof

    Sugru: Waterproof

    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.

  • Removable

    Sugru: Removable

    Once cured, Sugru can be removed* by cutting it off with a sharp knife. Remove any residue with fingernails and tissue paper.

    * from non-porous materials

Almost a million people in 157 countries use Sugru to help with everything from fixing their sink to paragliding and deep sea diving. Here are a few of the more extreme examples to give you an idea of its toughness and durability.

  • Sugru:

    Jim trekked to the North Pole with Sugru grips on his ski poles, where it needed to be the most comfortable shape for him and withstand temps of more than -25ºC.

  • Sugru:

    Lauren attached a camera to her aeroplane with Sugru, which turned out to be the only mounting solution that provides vibration free footage when she does her stunts.

  • Sugru:

    Stefan redesigned his camera to be drop proof so his 3 year old could take pictures, where Sugru needed to dampen vibration and bounce. Lots of others are doing this project now too!

  • Sugru:

    Joanne, who was born without fingers on her left hand, adapted her canoeing paddle with Sugru to be able to take part in the 715 km, 72 hours Yukon River Quest. Paddling for that long, soft-touch is a good thing!

  • Sugru:

    Franklin and lots of other people have repaired their dishwashers with Sugru where it needs to withstand harsh detergents and high temperatures on a daily basis.

  • Sugru:

    David resealed a link in the cooling system of his car where Sugru needed to withstand temps of 80°C (170°F) and high pressure too.

  • Sugru:

    Matt set his pupils a challenge: send a camera to space, photograph the earth and return it undamaged. The team, aged 11-14, used amongst other things a 1000g helium balloon, a polystyrene box and Sugru to hold the cameras in place. Everything returned in working order from temperatures of around -50ºC!

  • Sugru:

    John and the other engineers at his work wanted to put Sugru to the test. They patched a small hole in a water diffuser which had been spraying them for weeks. So far it's held up to 80 psi.

  • Sugru:

    Melanie used Sugru to adjust her glacier glasses to fit her perfectly. She replaced a scratchy duct tape hack with Sugru whilst on tour, just in time to climb a lovely mountain.

So Sugru is pretty amazing, and you should definitely buy some but what else do you need to know?

  • Shelf life

    Sugru will stay fresh for 13 months from the date it was made. If you use it within its date, the cured Sugru will last and last. (You'll find a Use By date on the back of each individual single use foil pack).

    PRO TIP: If you keep Sugru in the fridge, you can triple the number of months you have left!

  • Food safety

    Once cured, Sugru is inert, but people can be allergic to anything, so we have to tell you to be careful. Sugru isn't certified as food safe yet, but we're working on it. For now, please resist the urge to eat it.

  • Sugru + Kids

    Kids love Sugru - it's just like play dough when it comes out of the pack - but it's not certified as child safe, so it shouldn't be used by children.

The bit for material scientists, chemists and general nerds.

  • Have the normal people gone yet? Great. Let's talk technical. Sugru is a formulation of Formerol - the patented formable silicone technology invented by Jane. It's Formerol F.10, to be precise. We call it Sugru, because that's its superhero name.

    Formerol can be designed with variable physical properties, but Sugru is the best version for most people.

  • Sugru and Formerol are both listed in Material Connexion, MateriO Materia.nl, and universities around the world including Central Saint Martins College of Art & Design, Delft University of Technology, and Harvard University Design School

  • Sugru has a Shore A hardness of 70, Density of 1.3g/cm3, Tensile Strength of 1.89 MPa, Youngs Modulus of 5.59MPa, an Strain to Failure of 211%, DIN Abrasion Resistance of 24% ARI index (Standard used ISO4649 Method A), Electrical Resistivity - Surface 1.40 x 1014 Ohms (Standard used BS903), Electrical Resistivity - Volume 2.55 x 1014 Ohms (Standard used BS903), and a Williams Plasticity of 160mm. Phew.

    If you're still awake, you're one of us, and you probably want more technical details. Happy to help. You can download a PDF of Sugru's Technical Data Sheet (TDS) or Sugru's Material Safety Data Sheets (MSDSs): European version (English); United States version (English).
