What Is the Strongest Glue? ANSWERED

Technically speaking, the strongest adhesive in the world is version VE403728 of the product chain DELOMONOPOX. It’s highly resistant to surrounding elements and its resin components managed to set this global record.

Fun fact aside though, how strong any glue is will depend on the mode of application. Let’s face it, some adhesives are just better in woodworking than they are in putting glass together, for example.

This extensive guide will cover the types of glues needed to repair different types of common household materials. So, what is the strongest glue?

What Is the Strongest Glue for Wood?

If you’ve worked with wood before, you know how difficult it can be to use glue on it without ruining the material itself. Many have fallen into the mistake of using glue lying around the house to repair wooden furniture only to deface the wood’s grain and take away from its beauty.

That’s why you should know that the best and strongest glue for wood would be the Gorilla Wood Glue. Since it’s a polyurethane-based adhesive, it’s water-resistant, incredibly versatile, and doesn’t damage your wood.

Woodworkers swear by Gorilla Wood Glue owing to the fact that it’s effective with different types of wood, including hardwood and softwood. Not only that, but Gorilla adhesive is easy to apply since it dries off quickly and leaves behind a clean line.

Another advantage to Gorilla Wood Glue would be that it can be sanded down if needed, meaning, you can thin it out. It doesn’t expand or take too long to dry either.

What Is the Strongest Glue for Glass?

Glass is perhaps one of the most difficult materials to put back together. Most people choose to discard the broken glass rather than try to fix it. What happens though, if this glass was part of your morning cup or favorite chandelier?

The strongest glue to repair shattered glass has to contain one of two elements: epoxy or butyl. Such adhesives are specifically formulated to bond glass with glass, or with other materials if needed.

In our opinion, the ideal glue for glass is Loctite Glass Glue. Because Loctite is manufactured to dry off quickly and leaves behind a crystal clear residue, it won’t ruin the overall pristine look of the mended glass.

Additionally, Loctite’s components create an everlasting bond between the broken glass pieces once the glue sets in after a few minutes.

What Is the Strongest Glue for Steel?

Metals, such as iron and steel, have a surface with distinct qualities that makes it almost impossible to use your typical super glue. That’s mainly because metal exteriors don’t react with the organic molecules found in common adhesives.

Instead, what works well in gluing metal together would be products that contain binding agents and that’ll help grip the material. These adhesives are otherwise known as epoxy glues and are primarily made from a resin and a hardener substance.

Mixed together, these two parts are combined in equal quantities to create a glue that forms the strongest metal-to-metal bonds. As an added plus, epoxy-based glues are ideal when working with stone and concrete surfaces as well.

Due to their chemically-curated hardeners, epoxy products are not only resilient, but they’re also long-lasting and durable. As a result, they can withstand various environmental conditions.

What Is the Strongest Glue for Plastic?

Different types of plastic will each require a kind of adhesive that’s more suited to the material’s composition. You can determine which glue to use with your plastic by first looking for a number that’s typically engraved near the recycling symbol.

For instance, plastics that are marked with the numbers two, four, or five, are more difficult to glue back together than others. These plastic products will require adhesives that have polypropylene or polyethylene as their main binding agent.

On the other hand, plastics with the number six, or sometimes the letters PS written inside the recycling triangle, are easier to mend. Any epoxy or polystyrene cement adhesive will do just fine.

Finally, when repairing plastic goods labeled seven, nine, or ABS, it’s recommended that you use epoxy-based glue or one that contains cyanoacrylate as a fast-acting substance.

What Is the Strongest Glue for Cardboard?

Lucky for us, cardboard isn’t as tough as the other materials we went through above. The only hassle happens when you have to glue cardboard to more difficult elements, such as glass or metal.

First things first though, when gluing cardboard together, the strongest adhesive to use would be your typical, and most commonly used, PVA glue. This water-based, white-colored, and the non-toxic adhesive has long been chosen to put together school DIY projects and Halloween costumes.

That said, when sticking cardboard to ceramic or plastic, for instance, it’s better to use a more durable adhesive. Do this so the adhesive can bind to such distinct materials without losing its grip on one. Your best bets then, are to go for epoxy glue.

Remember that when using such a powerful adhesive like epoxy-based products, it’s advised that you apply them in well-ventilated areas. This helps air out the glue’s chemicals and foul odor.

What Is the Strongest Glue for Fabric?

Fabric can be quite hard to glue—especially when the aim is to create an outfit that’ll hold itself together. Many opt for the simple way out, namely using hot glue guns, but they’re not the most effective nor are they durable.

So, what’s the strongest glue for fabric then? For starters, the main characteristics you need to be looking for are an adhesive that’s machine washer safe and that doesn’t leave behind a yellowing residue after usage.

Aleene’s Super Fabric product is specifically manufactured to interact with complex fabrics and permanently hold them with one another. This heavy-duty glue creates flexible and resilient bonds while not leaving a trace behind.

Because Aleene’s glue is liquid-based, you don’t have to worry about using it on susceptible textiles either, including denim, wool, and cotton.

In Summary

What is the strongest glue, you ask? Well, the answer depends on the application. In other words, different glues are better suited for certain materials than they are for others.

Since each element reacts differently to an adhesive’s chemicals, it’s best to choose a glue that’s certain to bind well with the object’s surface.

We have discussed how you can get super glue off your fingers here.

To sum up, we hope our guide helped you figure out what glue to use with which material!
