What Glue for Magnets on Metal? Get my Top Tips Online!

When I started a project that included gluing a series of magnets to a metal surface, I learned a lot of valuable tips about which glue to use and some helpful methods for how to make the connection. So, I put together some of my top tips right here online to help others who might need some help with a similar task.

What is the best glue for magnets on metal? The best types of glue for magnets on metal include two-part epoxy glue, gorilla glue, super and crazy glue, as well as liquid nails and any kind of silicone adhesive. Remember,hot glue can damage most types of magnets. 

When it comes to craft and home improvement projects, there are dozens of reasons why someone would feel the need to glue magnets and metal together. However, most people are unaware of the best types of glue for each of these tasks. Keep reading for a quick and easy guide on how to choose the best glue for you.

Types Of Glue For Magnets On Metal

The process of gluing a magnet to a metal surface is actually a very smooth and easy process, as long as the right moves are made and the correct materials are used through every step of the way.

In order to avoid some of the most common mistakes that inexperienced DIY-ers commonly run into while gluing magnets to metal, skim through this convenient list of recommended glues that will be perfect for any type of magnet.

Best Glue For Magnets On Metal:

  • Two part epoxy glue
  • Gorilla glue
  • Super glue
  • Crazy glue
  • Liquid nails
  • Silicone adhesive

Since different types of magnets are made up of various chemical elements and other materials, some of them will not react well to certain kinds of glue that are involved in DIY projects.

The types of glue that are listed above, however, are generally safe to use on any category of the magnet. The best adhesive to look out for if you plan on gluing magnets to metal is two-part epoxy glue. The strength and durability of this type of glue are the most ideal for these types of projects.

However, if you do not have access to this specific type of glue, you can replace it with gorilla glue, super glue, crazy glue, liquid nails, or any kind of liquid silicone adhesive.

All of these brands and types of glue are strong and durable and will be able to hold the magnet upon the surface of your choice for long periods of time.

Using Hot Glue For Magnets On Metal

When the topic of gluing magnets to metal comes up, the concept of using hot glue is not usually thrown into the equation. In fact, hot glue is almost never recommended for these kinds of crafts and DIY projects.

This is due to the fact that the heat that is given off by hot glue can be very damaging to the magnetic fields of most types of magnets. If you are considering using hot glue to attach magnets to metal, you should make sure that the magnets you are using do not fall under the categories listed below.

Magnets That Are Not Compatible With Hot Glue:

  • Neodymium Magnets
  • Permanent Magnets

While neodymium magnets technically fall under the category of “permanent magnets”, there is an emphasis on the effects that hot glue has on this specific material.

While neodymium is one of the strongest magnetic materials that exist on earth, its levels of magnetic pull can be significantly damaged when it comes in contact with temperatures reaching one hundred degrees Fahrenheit.

Permanent magnets are also some of the most durable magnets in the world, inclusive of Samarium Cobalt, Alnico, and ceramic or ferrite magnets. If your magnets are classified by any of these names, you will definitely want to stay away from hot glue.

Magnets That Are Safe To Use With Hot Glue:

  • Small, Lightweight Magnets
  • Button Magnets

The only circumstances in which using hot glue on magnets is acceptable is when the magnets are more small and lightweight than the popular bar or disc magnets that contain neodymium.

Tiny button magnets, like the ones that are used to make used bottle caps into refrigerator magnets, will hold up fine using hot glue.

How To Make Sure Magnets Stick On Metal With Glue

Even though using a sturdy and reliable brand of permanent glue should be enough to hold up a magnet for a long period of time, there are some additional steps that you might want to take before attaching them to metal to ensure the most longevity.

With the combination of the right kind of glue and the most accurate steps from start to finish, you won’t have to worry about your magnets going anywhere after you glue them to the metal of your choice.

How To Make Sure Magnets Stick On Metal With Glue:

  • Make sure to clean the surface of the magnet and the metal before attaching
  • Scratch both surfaces after cleaning to create friction/a better grip
  • Apply the correct amount of glue with the added pressure
  • Allow the glue to dry completely while being firmly held for the best results

In order to make sure that your magnet will stay exactly where you glued it onto a metal surface, you will want to limit anything that could get in between the two objects.

This can be done by cleaning off both surfaces with warm water and a clean, damp cloth. By getting rid of any dust, crumbs, or scraps of metal, you will be able to rest assured that your magnet will not slip out of its position in the long run.

Additionally, you will want to use some kind of sharp metal object to scratch up the surface of both the magnet and the metal surface before applying the glue.

Since the surfaces of most magnets are smooth in texture, and the metal surface of your choice will most likely share the same characteristics, you will need to create some kind of friction or grip somehow.

Using a sharp nail, screw, key, or opened up a paper clip, you can create these scratches in all directions for the best results.

When you are ready to use the glue, you will want to only apply the necessary amount to the middle of the magnet. With just a small dot of glue on this surface, it will be able to spread out evenly in between the two surfaces for an even and stable connection.

Lastly, you will want to allow the glue to dry completely while you firmly hold the two surfaces together for the best results. A helpful tip to use during this process is to lay the magnet and metal down on a flat surface during drying if possible, to prevent the magnet from having to hold itself up before it has completely bonded with the metal.

To conclude, the best glues for magnets and metal can be found at any local hardware or grocery store, and the most effective adhesive bond between these two objects will be achieved with the right materials and a few helpful tips.

What are the three types of magnets?

The three main types of magnets are classified as temporary, permanent, an electromagnet. All of these magnets can be made up of alloy metals or a combination of chemical elements that create their magnetic forces.

What is the difference between an electromagnet and another type of magnet?

Unlike most types of magnets that contain chemical elements with magnetic properties, electromagnets consist of copper wiring and depend on the presence of an electric current to produce a magnetic field.
