Best Glue for Legos

Decorations come in many forms, and completed Lego sets are a popular decor choice for Lego enthusiasts. These building blocks are undoubtedly one of the most enduring and iconic toys in history. Many people even use glue to stick their Legos together to double as permanent decor, but what glues are best for the task?

The best glue for Legos has a narrow tip and low viscosity. Your options include Loctite and Gorilla Super Glue if you want a permanent solution that’ll dry within 10-45 seconds. Or, you can try products like Le Glue if you want a temporary solution — just add warm water to remove the adhesive!

This article will take an in-depth look at what glues are best for Legos, their pros and cons, and general information about using glue with Legos.

What Glues Are Best for Legos?

There are many reasons to glue Legos together, and they’re not all decorative. Sometimes, individual pieces just don’t stick together the way they’re supposed to. Or, maybe you have kids or pets that could ruin the whole set accidentally during playtime.

Regardless of why you want to glue your Legos together, you have quite a few options. From popular choices like Krazy Glue and super glue to more niche options like BrickShield and Le Glue, here’s what you need to think about first:

Considerations

When gluing Legos, there are a few things to look for in a glue. While some variants are functionally similar, they may have characteristics that make them unsuitable for use with Legos.

First and foremost, you need a liquid or gel glue that comes with a narrow tip. Right off the bat, this excludes adhesives like Elmer’s glue sticks.

Otherwise, you want glue that isn’t extremely thick because they’re not great for precision crafts work. Low viscosity glues that stay where you squeeze them and don’t create too much excess when applied are perfect for gluing Legos.

Loctite Ultra Gel Control Super Glue

This is the ultimate Lego glue. Loctite is super strong and adheres quicker than other glues, plus Loctite is water and fall resistant. These latter two features are crucial for Legos, which have a higher than average chance of falling or being disturbed – thus the need for glue in the first place! Loctite provides a clear and invisible seal while leaking very little excess glue upon application.

The only caveat of Loctite is that the application is permanent, so it’s not the best if you want to take the Legos apart eventually. But for the cases when you have a beautiful set that’s going on display forever, Loctite is just the glue you need.

Gorilla Super Glue Gel

When you need a strong seal with a very clean presentation, this is the glue product for you. Gorilla Super Glue Gel is a cyanoacrylate glue specifically created to provide impact protection with an application that doesn’t run and sets fast.

Gorilla Glue dries in 10-45 seconds, which means gluing your set together isn’t a week-long endeavor. With a narrow, clog-free tip and the touted impact protection, it’s not hard to imagine using this glue on your favorite Lego sets.

Le Glue

When you want to glue a Lego set for some time and eventually take it apart, you can’t go wrong with Le Glue, a glue specifically created to create a strong bond that you can easily remove. With a narrow tip, this glue easily sticks Legos together, and removal is dead simple: just add warm water, and the bond dissolves!

Sometimes you want to make a temporary display that’ll go back into the toybox one day, and Le Glue is the perfect temporary glue for the task.

Rhino Glue

This heavy-duty glue is along the lines of Gorilla Glue in that it creates a rock-hard bond in mere seconds. This formula provides shock, impact, moisture, heat, and vibration resistance to the final product. Those are some of the best protections a glue can offer a Lego set that could face rambunctious children or a future move.

You can’t always tell what hazards a displayed Lego set may face, but with Rhino Glue, you don’t have to worry about any of them.

BrickShield Plastic Brick Glue Spray

This unique adhesive offers a spray alternative to all the narrow tip glues seen here so far. BrickShield glue is specifically created to be easy to apply and remove. Similar to Le Glue, BrickShield glue easily washes off when run under warm water. This offers a neat solution to kids who might want a ‘permanent’ Lego set one day and change their mind the next day.

Final Thoughts

Whether you want to bond a Lego set for today or years to come, there are many options available to you. For permanent bonds, you can’t go wrong with Loctite or Gorilla Glue, whereas Le Glue and BrickShield provide temporary solutions to fickle Lego builders who might want to take it apart one day.
