Getting to know metal glues
Got something metal that needs fixing but not sure where to start? Choose the best glue for metal with our guide to the different types of metal glue.
When it comes to fixing metal, there are three types of metal glue to keep an eye out for: epoxies, polyurethanes and super glues.
Epoxy adhesives form the strongest metal-to-metal bonds. They consist of two parts – the adhesive and the hardener. These combine to create strong, long-lasting bonds between different types of metal or between metal and concrete surfaces.
For metal you may want to find yourself a two-part epoxy adhesive. These dry quickly, some within five minutes and are ideal for quick DIY jobs that require permanent bonding. You can also use these epoxy glues to repair and fill gaps in most types of metal and stone.
Polyurethanes are another common type of glue that can be used on metal. You can normally identify polyurethanes because of their water-resistant and UV-resistant qualities. These are another great option because they dry quickly without becoming brittle. These single-part glues need moisture to set but are waterproof once cured.
Another benefit to using polyurethanes is that once they’ve dried completely, they can be sanded, stained, and painted. Since it doesn’t shrink, they can withstand extreme temperatures and can be painted over, this glue is great for DIY jobs like fixing your oven door, saucepan handles and radiators.
You may be wondering, “Does super glue work on metal?” It most certainly does. Super glues are based on ethyl cyanoacrylate. These single-part glues are great for creating fast, strong bonds between metal surfaces. Super glues can stick surfaces together almost instantly, which makes them great for almost all metal-to-metal applications, but they can't fill in gaps.
For fast and strong results, use Loctite’s 60 Second All-Purpose glue. This versatile and reliable super glue dries transparently and forms long-lasting invisible bonds between metals in just a few seconds. It’s extra strong which means it can be used for all types of home repairs involving metal, even everyday tasks like reattaching saucepan handles or fixing your bike.
