How to use Sugru

How to best apply Sugru to ensure a strong bond?

Smooth Surface

If you’re applying Sugru to smooth surfaces, press Sugru firmly onto the surface, and then press it down along the edges so that there is no shadow/gap where the Sugru and surface meet.

To successfully apply Sugru to any smooth surface, follow these handy tips and you will have a super strong bond!

1. Cut open your single-use foil pack by using scissors along the dotted line.

2. Roll Sugru in your fingers for 30 seconds. If you find that Sugru is sticking to your fingers, use a piece of dry tissue paper to wipe them clean.

3. Ensure your surface is clean, dry and free of dust and grease - use some dry tissue paper to wipe it clean.

4. Push your Sugru firmly onto your surface.

5. For the maximum strength bond, make sure that you can see no join or shadow between the Sugru and the surface.

6. Top tip: for a smooth finish, dip your fingers into some soapy water and gently rub the surface.

7. When you are happy with your fix, leave it to cure for 24 hours!

Porous Surface

If you’re applying Sugru to porous surfaces, the key is to smear a thin base layer of Sugru and then build more Sugru on top of that (Sugru bonds brilliantly to itself). You can learn how to do it by watching this quick video tutorial.

Mounting & Attaching objects

If you’re mounting something or attaching objects together, this useful video guide will show you how to do it. Basically, you need to press a blob of Sugru onto object A, shape the Sugru into a pyramid, and then press firmly onto object B, so that Sugru is squished between the two surfaces and oozes over the sides. To avoid Sugru being pulled away from surfaces while curing, we’d recommend securing the attached object in place with a strong tape (masking/painter’s tape works very well, for example).

Is Sugru removable?

Absolutely. First, simply cut off the bulk of the Sugru using a knife or scalpel. You can then remove the residue with your nails and some tissue.

If using Sugru on porous surfaces such as walls, unglazed ceramic surfaces or unvarnished wood, it is still removable, but may leave a stain.

As for fabrics and leathers, once you’ve worked Sugru into fabric or leather, it may be difficult to remove completely, and is likely to leave traces.

If I’m not going to use the whole single-use pack, can I save the leftovers for later?

Once you cut open the single-use pack, the moisture in the air will trigger the curing process. We tested a few methods of preserving Sugru and haven’t found a reliable way to save the leftovers yet, so we recommend lining up a few projects to make the most of Sugru in one go.

PROFILE

We’re FORMFORMFORM, a small but perfectly formed team of inventors, material scientists, designers, video makers, business and production people based in Hackney in East London. Sugru is our first product, and we’re growing quickly!

We’re on a mission to help the world get fixing and customising again. It’s not about ‘making do’ though – it’s much more than that. It’s about taking control and repairing, modifying and evolving the products we own so that they work longer, harder and better for us. Sure, it’s economical and sustainable, but most of all, it just makes sense.

(In 2018, FormFormForm was acquired by German adhesive company Tesa SE, a subsidiary of Beiersdorf.)
