Can You Hot Glue Metal?

Gluing metal can be a hard task for multiple reasons. Because metals are non-porous, glues cannot penetrate the surface. Hot glue has solved these obstacles, and it is now possible to bind metal to metal, cloth to fabric, wood to wood, and glass to glass. You can simply hot glue metal by following the easy directions in this tutorial.

Hot glue is suitable for both porous and non-porous surfaces. Because of its high viscosity, it can adhere uneven surfaces together and fill gaps effectively. When bonding metals, the two metal surfaces must connect with one other for a strong, long-lasting bond. If the surface is rusted or painted and the layer is not removed, you are bonding rust to rust or paint to paint.

When you apply pressure to the bonded metal, the paint or rust adheres securely to the glue but pulls away from the metal surface, causing the connection to dissolve.

Can You Hot Glue Metal?

Yes, hot glue works well on the surface of the metal. Hot glue seems to be the best all-around general adhesive that works on most surfaces, including metal and plastic. Metal surfaces tend to stick better if you give each surface light sand with fine-grit sandpaper before you attempt to bond it. There are a couple of techniques to follow for gluing metal properly.

How To Hot Glue Metal?

Metal gluing is a simple process that just takes a few stages. Hot glue does not adhere well to flat surfaces such as metal, but we have a terrific way for you to hot glue on metal in no time.


  • Work in a well-ventilated room or site that allows adequate space to handle all the items.
    Cover up furnishings with protective clothing or old newspapers.
    Examine and test the fit of the pieces to be linked.
    Remove any shards or particles that are blocking a seal.
    Wear latex or nitrile gloves while hot gluing metal to protect your skin.

Clean the metal

  • The most crucial step is to clean the metal surface before gluing.
    The surfaces must be clean and dry. With a cloth, remove any dust, debris, wax, oil, or grease, including fingerprints, from all parts.
    Tip: Sand the surface of metals using fine-grit sandpaper to help hot glue adhere correctly.

Apply Hot Glue

  • Before using your product on metal, read the directions.
  • The following step is to apply hot glue. Open the hot glue cap and dab it on the metal surface.
  • Use the amount recommended in the hot glue product’s instructions.
  • Join the metal parts together.
  • Position the pieces and firmly push them together to achieve a tight seal with no gaps.
  • Finally, wait 24 hours for the adhesive to set properly.

Tips For Hot Gluing Metal

  • Because of its gleaming and nonporous surface, metal is notoriously difficult to bind. But nothing is impossible for those who strive. We have some simple hot-gluing suggestions for metal.
  • If you’re using a glue gun, be sure the hot glue is thoroughly heated.
  • Clean the metal’s surface completely, removing any dirt, grease, or oils.
  • Metals should not be cleaned with solvents such as alcohol, acetone, or citrus-based cleaners.
  • A metal’s surface may be cleaned with mild soapy water.
  • Roughen the surface of a metal using grit sandpaper to promote adhesion and provide the bond a greater hold on the surface.
  • It is preferable to preheat when bonding metal to metal.
  • We recommend you to use Surebonder glue sticks for best results. 

Can You Hot Glue Metal To Metal?

You can hot glue two or more pieces of metal together without welding or any other difficult method. Fortunately, hot glue can be used to connect metal to metal. Always follow the manufacturer’s safety recommendations to avoid injury.

Step By Step:

  • A strong metal-to-metal adhesive connection is ensured by careful pretreatment of the metal surfaces.
  • Remove any paint, rust, or corrosion from metal surfaces with a scraping or sanding tool, then remove dust, dirt, wax, oil, or grease with a cloth or paper towel dampened with a degreaser or detergent.
  • When cleaning and bonding metal, work in a well-ventilated location or outside, and avoid breathing glue fumes as you assemble pieces.
  • To create texture, sand the two surfaces with fine-grit sandpaper. This makes it easier for the pieces to join.
  • Hot glues are the most effective in forming metal-to-metal connections.
  • Apply hot glue to the prepared surface as directed by the manufacturer.
  • Metal-to-metal hot glues often tell users to clamp the components together for the first 1 or 2 days as the adhesive cures, but to wait up to 24 hours before resuming usage of the bonded object.
  • Because most high strength glues go through a chemical curing phase before they are totally secure, you will acquire a stronger connection this way.
  • Follow the drying time frames specified on the glue’s box to ensure that the two components have enough time to bind.

Final Verdict

Metal may be bonded to any surface or metal to metal using hot glue. Before attempting the bond, remove any surface materials or debris from the surfaces. This contributes to the strongest and tightest structural link possible.
Additionally, test your adhesive on a tiny piece of surface. If the adhesive creates beads on the surface, it isn’t suited for bonding that specific type of metal. After a minor abrasion, try it again.
You should be able to evenly apply the adhesive throughout the surface. If it distributes evenly without producing beads, you’ve found the proper adhesive for the job.
