How to use Sugru Mouldable Glue
Sugru is the world’s most versatile and creative glue that turns to rubber. Learn some basic techniques.
How to stick things together with Sugru
When gluing things together, it’s generally best to stick the smaller or lighter object to the larger heavier one.
- Roll the Sugru into a small sausage and press onto the smaller object.
- Shape the Sugru into a cone.
- Press the smaller object, cone first, onto the larger object.
- Use fingertips to smooth out any excess Sugru that has squeezed out.
Pro tip: This technique can also be used when working with round or curved objects.
How to apply Sugru to rough & porous materials
If you're applying Sugru to porous surfaces such as unpainted walls, unvarnished wood, unglazed tiles, or fabric, first create a sticky base layer by smearing a small amount of Sugru onto the surface, then apply more. Do this in one go as there is no need to wait for the base layer to set. (Sugru bonds brilliantly to itself).
- Take a pea-sized piece of Sugru and smudge onto the surface.
- Work the Sugru into the area.
- Add more pea-sized pieces as required.
- If the application needs to be flexible, only use a thin layer of Sugru.
- Otherwise, you can build Sugru directly onto your base layer.
How to keep your fingers clean while using Sugru
If Sugru starts sticking to your fingers, simply use dry tissue paper to wipe it off. This will make handling Sugru a lot easier.
How to make your Sugru fixes look awesome
Sugru works well no matter how good, bad, or ugly the fixes look. But it's really easy to make them look gorgeous. Try these techniques.
- Push the Sugru into place and shape with your fingers.
- For a precise edge, use masking or painter's tape.
- Rub soapy water onto the Sugru to achieve a nice, smooth finish.
- Use everyday objects to create different textures (toothbrush, scalpel, thimble).
- Embed different materials into the Sugru.
Pro tip: If your texturing tool sticks to the Sugru, just dip it into soapy water. Alternatively, use cling film (Saran wrap) or something greasy like petroleum jelly (Vaseline) to prevent Sugru from bonding to surfaces you don't want it to.
How long to leave your Sugru to set
Sugru sets to 1.5mm in 12 hours, 3mm in 24 hours and thicker applications may take longer. For load-bearing projects, or if Sugru's exposure to air is limited when squished between surfaces, allow up to 48 hours for it to fully set. Use Sugru at room temperature for the best results. Colder temperatures slow down the setting times.
Pro tip: To avoid Sugru coming away from surfaces while setting, we recommend securing the attached object in place with masking or painter's tape.
How to sand & craft fully set Sugru
Even after Sugru has set, there is still more you can do to embellish it.
- Sand it to create a suede effect.
- Cut, carve and craft it into any shape with a scalpel or sharp knife.
- Sugru bonds brilliantly to itself, so you can build onto it.
- Or remove it completely.
Note: Sanding Sugru will create a more porous surface. Please ensure that you wear a mask when sanding to avoid breathing in the dust.
How to use Sugru to mount & hang objects
Sugru is great for mounting, but don’t use it to hang objects heavier than 2kg/4.4lb. Always test the holding power of Sugru before relying on it. Simply mount your object with Sugru, then secure it in place for up to 48 hours using masking or painter's tape.
How to keep your unopened Sugru fresh
See the use-by-date on the single-use packs. If used within this date, the set Sugru will last and last. Keep unopened packs of Sugru in the fridge to triple the number of months you have left for use.
