Q: Can Sugru stick to metal?
A: Yes! Sugru bonds well to metals, as well as many other materials, but like most adhesives Sugru may struggle to bond to certain powder-coated metals. For tips on how to stick Sugru to metal, check out our How to use Sugru page here.
Q: How long will Sugru last on metal?
A: Sugru bonds permanently to metal, the same way it does on other materials. If you'd like to remove it at a later date, that's possible, check out our guide on removing Sugru here.
Q: How long does Sugru take to set on metal?
A: 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. Always test the holding power of Sugru before relying on it.
Q: Do you have any tips for using Sugru on metal?
A: If you've followed the steps to bond Sugru to a smooth surface (you'll find them here), and you're still having trouble, you can sand or scratch the surface before applying Sugru, this gives Sugru more grip on your fix.
