Legos are fun for all ages. What started out as a simple toy block company from Denmark has boomed into the massive toy tycoon powerhouse that it is today. In these modern times of Lego you can find Lego sets ranging from simple to massive and complex. Famous franchises such as Harry Potter, Star Wars, Marvel, and even the Lord of the Rings all have their own custom Lego sets that you can buy and build. 

While the main purpose of a Lego set is to build and create, some people don’t want to have their sets falling apart anytime soon–if at all. That is why lego gluing is a relatively popular process among hobbyists and Lego lovers alike. Gluing your Lego sets allows you to keep them in shape and on full display forever without fear of a piece popping off and disappearing–or being eaten by the dog. 

While Lego gluing may be popular, for some the concept is still pretty new. That is why the question of ‘which glue to use’ often comes up. So, down below our team at Cleaning King is going to dive into the topic of Lego glue. We will discuss which glues we believe are best for the job, and what things to consider when buying glue for your legos. 

Our adhesive experts here at Cleaning King have carefully reviewed several glue options for use on your Lego playsets. Here are the options that we have determined are the best of the best. Let’s get started!

Our take – Best Glue for Legos

Elmer’s Glue has been a staple in the craft and hobby scene for over 70 years. Their classic name is ubiquitous with quality when it comes to having the trust of all things arts and crafts. The Krazy Glue formula by Elmer’s is no exception to their excellent reputation. This is an extra strength craft glue that will ensure your blocks don’t come apart any time soon. 

Krazy Glue is a very tacky glue that spreads easily and can be controlled without causing a mess or mishap during application. What’s more, the precision tip adds just a bit more accuracy when applying the glue on the Lego blocks. This makes Krazy Glue a great option for beginners as the application process is smooth and easy. Overall Krazy Glue is easily the best option for those new to gluing their Lego sets. Better yet, Krazy Glue is trusted by Lego Master Builders and experts alike!

Stand-out features include

– Tacky formula for smoother application.

– Minimal odor. 

– Extra strength hold. 

– Water resistant.

Our take – Best Glue for Legos

Gorilla Glue is a name synonymous with extra strength hold. Almost everyone who has ever sought after an adhesive has heard the name Gorilla Glue. Gorilla Glue is known for insanely fast drying times, impossibly strong holds, and overall great quality. That is why for almost any adhesive need, Gorilla Glue is going to pop up as an option to consider. 

The Gorilla Super Glue Gel is their super glue formula. This formula is a thick gel that makes spreading and application very easy. When gluing Legos, you need an adhesive that isn’t too thin so as to avoid the glue spreading everywhere and creating a mess. This glue is the perfect thickness for easy application. Even better, it dries in as fast as 10-45 seconds! Overall this is a great option for those who want fast results that will last a lifetime.

Stand-out features include

– Gel formula for consistent application. 

– Extremely fast drying. 

– Lifelong hold.

Our take – Best Glue for Legos

Le-Glue is one of the two glues on this list that are designed specifically for Lego bricks and similar brick style toys. Le-Glue is an excellently designed product that makes adhering bricks to each other a breeze with a thick formula that spreads easily and dries quickly. It will provide you with a strong hold that can ensure that none of your pieces pop off or remove easily during play time or display. 

The best part about Le-Glue is that it is a temporary Lego brick glue. That means that it can be removed for whenever you want to disassemble your set. The formula is made to dissolve in warm water easily. This makes it easy to remove from your hands after use, and to keep your sets from being permanently glued once set. For those who don’t wish to commit to a permanent gluing, Le-Glue is a great option!

Stand-out features include

  • Water-soluble formula. 
  • Quick drying.  
  • Non-toxic.

Our take – Best Glue for Legos

Back with another entry to the list is Gorilla Glue. This adhesive is a bit different when it comes to application, as it is a spray adhesive as opposed to a liquid or gel. The spray adhesive is applied in a thin layer over the Lego set after assembly, and provides a secure hold to the bricks from the outside. This makes applying the adhesive easier and faster than ever before. 

The best feature of the Gorilla Glue Spray Adhesive is that it has a completely clear, non-yellowing application formula. When dried, this formula provides a completely clear coating to the Lego set that won’t discolor over time. In addition, the thin layer of adhesive is very shock-resistant. This means that it will hold up even during play–or drops. This is a great adhesive for Legos when it comes to ease of application with a quick dry.

Stand-out features include

– Clear dry formula. 

– Dries in seconds. 

– Shock-resistant.

Our take

BrickShield Brick Spray is one of the most trusted brick glue adhesives for brick lovers around the world. It is the perfect blend of what we love about the Le-Glue Temporary Glue and the Gorilla Glue Adhesive Spray. This is a spray-on glue that is applied to the Lego set in a thin coating that binds and holds against all use and abuse. And the best part is, it’s temporary! 

The BrickShield Brick Spray is water-soluble, which means that it will come off completely when washed with warm water. This makes it ideal for those who don’t wish to commit to a permanent binding, but also want something exceptionally easy to apply. With a clear drying sheen, this spray on glue is virtually unnoticeable as well. This is the perfect adhesive for Lego lovers who want their playsets to hold together under use, but only for as long as they wish.

Stand-out features include

– Fast drying. 

– Simple application. 

– Temporary/removable.

What to look for in the best glue for Legos

Now that we have had the time to go into the best glue options for brick lovers, it’s time to talk about what you need to know for buying. Our team at Cleaning King knows glue, and we make it our mission to help relay our knowledge to you. So, let’s talk about some of the

important things you should keep in mind when making the choice for which glue is best for you–and your Legos. 

Choosing Permanence

When buying any glue, you would normally always want the glue to last forever. That is, afterall, the purpose of glue. However, when it comes to Legos, permanence might not always be what you are looking for. This is because many Lego lovers like to disassemble and reassemble their sets over time–that’s the fun of Legos! So, with this in mind, you should always consider how permanent you want your hold to be. Temporary versus permanent should be your #1 thought when buying glue for Legos. 

Application Method 

Applying glue to Legos is sometimes a bit of a messy task. The glue can get all over the place, and fingers can quickie become stuck to bricks if you aren’t careful. That’s why it’s important to choose a glue that has a simple and efficient application process–even if you’re an expert. Choosing precision tipped glues is ideal for thick liquid/gel style glues. You can also choose to use spray on adhesives which can be easily applied in a thin coating after building. The choice is yours, but is something that should be considered! 


Durability is one of the most important aspects of an adhesive, especially for models and Lego playsets. You want something that can hold your bricks together when the set is being used or played with. This means that you want to look for a glue that can absorb shock, and maintain a hold even under a bit of stress. Super Glue formulas are going to be the strongest hold, but these come at the price of being irreversible once applied. If you are looking for a temporary glue, make sure to use one that is designed for Legos specifically. 


Lego sets are designed to be attractive and fun. They are made to be shown off, played with, and looked at by all. That means that you will likely want them to look just as good as they were meant to. Maintaining aesthetics is difficult to do with glues that dry white or discolored. This means you will want to find a glue that dries clear every time. It doesn’t matter if you use a liquid glue, a gel, or a spray adhesive, you want a clear drying glue that won’t ruin the look of your playset once set and dried.

Conclusion – Best Glue for Legos

When it comes to choosing the best glue for Legos, there are no shortage of options available to you. It all comes down to your own experience level and needs in general. However, that doesn’t mean that we haven’t been able to come up with a verdict. 

Ultimately our team at Cleaning King believes that Elmer’s Krazy Glue is the best overall glue for Legos. It is easy to use, dries quickly, and applied evenly with very little mess or fuss. It is a permanent adhesive, which should be noted. However, for hold, longevity, aesthetics, and ease of use, it is hard to beat.

Best Glue for Legos FAQs

Whether or not you glue your Lego sets is up to you ultimately. Many collectors will choose to glue their sets together for better durability when displaying them. Other Lego lovers will glue their sets to keep them in-tact when playing with them. However, if you ever plan on reselling your lego sets, you should never glue them. Gluing them ruins any resale value they have. But, for those who don’t care about resale value, gluing your lego sets is perfectly fine and normal.

If you want to keep your Lego sets in tip-top shape, then it’s honestly best to avoid gluing them altogether. Legos are not designed to be held together forever. Gluing your Legos is, by nature, going against the grain a bit. Some compounds have a tendency to damage or discolor the plastic of the bricks when used improperly. In addition, permanently binding the Legos can ruin the resale value completely. This is a risk you have to keep in mind when choosing to glue your Lego playsets.

Most glue adhesives are semi-permanent. Depending on the compound they can be subject to erosion and damage over time that can lead to the failure of the glue over time. However, some stronger glue formulas are about as permanent as you can possibly expect. That being said, temporary glue options are also available. So, in short, glue is only as permanent as you want it to be!

If you want to playback your home’s outdoor activity, you’ll need a camera with onboard video storage or cloud recording capabilities. Most cameras with recording capabilities have a built-in secure digital (SD) or microSD slot that allows for sufficient recording space. Once the memory card is full, you’ll need to delete footage or store it elsewhere. Some popular cameras automatically override expired videos, which may not be most ideal if you need to keep a video. On the contrary, some security camera providers offer cloud storage monthly plans to securely store videos on the cloud. You can easily access them anytime, anywhere by signing into your account on your mobile device or using a mobile app.

Lego sets can absolutely be glued together without issue for the most part. While certain compounds should be avoided on the plastics of Lego bricks, they are generally durable when it comes to resisting adhesive damage. Plenty of hobbyists and Master Builders glue their ambitious Lego creations for permanent or temporary display.
