Best Polyurethane Metalworking Glue
The best polyurethane glue for metalworking is Gorilla Glue. Gorilla Glue has an incredibly strong bond and can be used both indoors and outdoors. Gorilla Glue’s strength comes from the fact that it expands when it is applied, giving it a stronger hold than many other polyurethanes, which is why it works so great on metal. Gorilla Glue is also paintable, so it can blend in perfectly to whatever metalworking project you are working on.
How to Glue Metal to Metal
- First, you need to prep your two metal surfaces by cleaning them of any rust, dirt, or grease.
- After that, you can take some fine-grit sandpaper and rub it on the metal surfaces to roughen the texture to ultimately create a stronger bond.
- From there you can take your adhesive of choice. With epoxy, don't wait longer than 2 minutes after application to press the metals together.
- For polyurethanes, after pressing the metals together, clamp them for 2 hours.
- Regardless of which adhesive you use, leave your metals to cure for 24 hours after application.
