Can You Hot Glue Lego?

Can You Hot Glue Lego

Using hot glue is not the best method for attaching LEGO pieces. Although it is possible to attach LEGO pieces using hot glue, it is not the best method for attaching LEGO pieces. 

There are many other types of glue aside from hot glue that can attach LEGO, such as Elmer’s Glue.

LEGO has a high melting point, which means that hot glue will not melt the pieces if used to attach pieces. But the seepage on the side of pieces attached with hot glue can be unsightly. Using a method such as cyanoacrylate glue is more likely to bring you an aesthetically pleasing result.

Will Hot Glue Melt Lego?

Hot glue will not melt LEGO pieces. LEGO makes all pieces at an abnormally high melting point of 105°C (221°F). The high melting point means that normal LEGO bricks will not melt under normal circumstances like using hot glue to attach pieces. 

What Is the Best Glue to Use on Lego?

The best type of glue for LEGO sets is cyanoacrylate (CA) glue. These are long-lasting glues with maximum strength. They are great for LEGO sets because they are designed to hold pieces together even if they are dropped or constantly handled. It is a great choice for people who hang LEGO sets or are trying to experiment in new, unique designs. 

However, these are permanent glues that can damage your LEGO. That is why there are several other types of adhesives that you can use to attach your LEGO pieces. 

The most common secondary adhesive that many people use to attach their LEGO pieces is paste. There are many brands that offer paste glue and it can be found in nearly any store.

Cyanoacrylate glue is the most common type of glue recommended for attaching LEGO pieces. This glue is a long-lasting glue that is known to last a long time. This type of glue is reliable and often used because of its precision. 

Gorilla Glue is one of the most highly recommended cyanoacrylate glues for attaching LEGO pieces. This brand is a maximum strength glue used by many LEGO lovers. The precision tip on the Gorilla Glue dispenser makes it easier to dispense glue onto tiny pieces without excess.

  • Krazy Glue

Many brands design their cyanoacrylate glue with permanent use in mind. The instant adhesives focus their attention around creating heat, weather, and water-resistant glue that will hold your pieces together even if they drop!

Glue paste

A glue paste is a common type of glue that many people use to attach their LEGO pieces. Glue paste is great for attaching LEGO pieces mainly because it has a very minimal impact on LEGO pieces and is easy to clean off. You may use glue paste in white and clear, making it a benefit when attaching dark colors.

The most common type of glue paste is Elmer’s glue. Elmer’s glue is a great glue for building LEGO sets because of its affordability. It is also a common glue that LEGO builders can purchase at nearly any store.

Sticky Tack

Sticky tack is an adhesive substance that many LEGO builders have begun to substitute for traditional glue. This substance allows builders to attach their pieces without leaving behind a residue as cyanoacrylate glue does. Sticky tack is a doughy substance that can be removed and reused several times. It is best for temporary, short-term use because it does not have as strong of a hold.

How Do You Glue Lego After Building Them?

You cannot glue LEGO blocks after you build them, so you must glue LEGO blocks as you build your LEGO set. Gluing your LEGO pieces as you build them guarantees that you have a firm hold. If you try gluing your set after building it, the structure will not be sturdy.

How Do You Glue Legos?

Glue pieces together by placing the glue directly onto the small holes. Putting glue into the holes is a good way to guarantee that glue does not spill over the side. For larger pieces, you may choose to place glue directly on the prongs. 

Either way, you should place a tiny droplet on each of the holes or prongs before firmly placing it where you want the piece to go. Hold the LEGO piece in place for at least three seconds before carefully letting go. Do not remove the piece after laying it down.

It is important that you plan where you will place your LEGO pieces before putting glue onto your pieces. After putting glue onto your piece, you will only have a few seconds to place it before it dries. This is especially applicable if you are using cyanoacrylate glue, which dries extra quickly.

Is There a Specific Glue for Lego?

There is a standard glue recommended for LEGO pieces called cyanoacrylate glue. Many LEGO builders refer to this glue as CA, for short. Cyanoacrylate glue is a fast-acting adhesive, which quickly bonds the pieces together. LEGO builders use this glue because it dries almost instantly and holds firmly. 

Cyanoacrylate glue is important when crafting permanent LEGO sets because of its extra-strength hold. This glue lasts a long time and is difficult to remove.

Final Thoughts

Hot glue will not harm LEGO pieces. Fortunately, the high melting point of LEGO means they are resistant to melting under the pressure of hot glue. However, it is not the most effective way to permanently attach your LEGO pieces.

The best glue for LEGO sets is cyanoacrylate glue. These glues are effective at attaching and bonding LEGO pieces within seconds. Brands such as Gorilla Glue are great examples of a type of fast-drying cyanoacrylate glue that bonds LEGO pieces together into solid, long-lasting structures.

It is critical that you glue your LEGO pieces as you build. You cannot glue your set after you have completed your build. There are thousands of glues that you may use, depending on your intention with the build. These include permanent and temporary glues that accommodate everyone’s desires for their LEGO builds.
