Super Plastic Glue Bottle Mockup

1. Gorilla

Let’s start with a brand that most people know — Gorilla, a manufacturer that has consistently produced the best quality adhesives. And if you want glue for permanent Lego constructions, then this product is bound to be a good choice. 

Gorilla Super Glue Gel, 20 Gram, Clear, (Pack of 1)
  • GEL FORMULA: No run control gel formula that is great for...
  • ANTI CLOG CAP: Helps keep the glue from drying out. It's...

Why Did We Like It?

There are several things to like about this Gorilla super glue. But, first, we would like to divert your attention towards its consistency. Unlike any other liquid glue, this formula comes in a thick gel, making it easy to apply on vertical and horizontal Lego pieces. That said, the no-mess Gorilla glue makes the application process easy as the glue won’t get everywhere. 

Another key feature of this glue is its packaging. You can now hold the cleverly-designed compact plastic bottle in your hand for long hours while working on an intricate project. 

However, what probably stands out the most is the anti-clog cap, which keeps the Gorilla glue from drying out, thus allowing multiple uses with each bottle. 

Furthermore, the Gorilla super glue gel takes between ten to forty-five seconds to set, based on the amount of glue used. And, as it gets fully cured in 24 hours, you wouldn’t need to wait for days before handling the Lego construction.

What Could’ve Been Better? 

Overall, this is one of the best permanent glues for Lego blocks. But, our only concern is that laying down a thick layer of Gorilla glue may leave a visible gap between the blocks. So, you need to be a bit more careful while using the glue and only apply a few drops. 

Pros
  • Easy to use
  • Dries transparent
  • Ideal for intricate projects
  • Versatile adhesive
Cons
  • Thick layer may increase space between pieces

2. Loctite

For the last 50 years, Loctite has remained a leading brand of permanent glues available on the market. The best thing about this product is its innovative formula that promises versatility and durability. And, as it’s widely available from different retailers, you won’t have a hard time searching for this super glue

Loctite Ultra Gel Control Super Glue
  • Rubber-toughened, instant adhesive resists impact, shock,...
  • Ideal for metal, rubber, ceramics, wood, leather, paper and...

Why Did We Like It?

To begin with, what pulled us towards this product was the packaging. We really liked the bottle design, which is equipped with squeezable sides to make the application process easier. What’s more, the sides have grooves to help you maintain a better grip on the bottle. Not to mention how the precise nozzle lets you apply drops of glue even on the tiniest of Lego bricks. 

However, the property that truly makes this permanent adhesive a worthy product is its unique formulation. That said, it is a rubber-toughened glue that allows bonds to be flexible while also giving it the ability to resist heavy impact and vibration.

Moreover, this glue dries clear, so you wouldn’t need to worry about any traces showing through the Legos, especially between darker colored pieces. On that note, the transparency provides a seamless look to the blocks when the right amount of glue is applied.

What Could’ve Been Better? 

One of our only concerns with this glue is that the product may build up on the applicator if it isn’t cleaned after every use. So, you should always remember to wipe off the applicator with a paper towel to prevent it from clogging. Also, refrain from keeping the bottle uncapped for long periods.

Pros
  • Easy to dispense
  • No clamping required
  • Suitable for vertical Lego surfaces
  • Fast drying
Cons
  • Applicator needs to be cleaned after every use

3. GLUEMASTERS

Are you in search of a permanent glue that won’t lose its bond even after years? If yes, you can try this adhesive from GLUEMASTERS, which boasts an industrial-grade formula. This makes the glue excellent for all kinds of projects, from Lego construction to fixing heavy-duty machines. So, let’s check out its features.

Professional Grade Cyanoacrylate (CA) Super Glue by Glue...
  • ★ One Glue To Rule Them All – Glue Masters offers...
  • ★ A True Quick Fix – Settles in just under 60 seconds,...

Why Did We Like It?

If you are a hobbyist who likes to indulge in different projects, it’s a must to have this GLUEMASTERS professional-grade adhesive. It comes in various viscosity levels to choose from, but we recommend the thick variant for Legos as it works well for vertical surfaces. Nevertheless, this glue is available in different quantities, including an 80 oz bottle. 

However, the best feature of this glue has to be its precise applicator. The nozzle allows you to place the smallest drop of adhesive on the Lego blocks before attaching the plastic pieces. Additionally, the bottles are only filled to two-thirds of the total capacity to give you more control while applying the glue. 

Besides its function as glue for Legos, this professional-grade glue is quite versatile. You can use it to bond materials like rubber, ceramic, wood, metal, and other plastic objects. Needless to say, it’s a helpful glue to have in your toolbox.

What Could’ve Been Better? 

Although not a dealbreaker, its industrial formulation is only suitable for use in a well-ventilated space. The manufacturer also suggests using protective gear, like gloves and goggles, to keep yourself safe from coming in contact with the glue. Apart from this, we don’t have any complaints about this permanent glue. 

Pros
  • Durable bond
  • Applicator doesn’t clog
  • Available in larger sizes
  • Versatile adhesive for different materials
Cons
  • Needs to be used in a well-ventilated area

4. Rhino Glue

Have you been looking for cyanoacrylate-based hobby glues for permanently bonding your Lego construction? If so, this heavy-duty Rhino glue can be an excellent choice to finish the task as fast as possible without the Lego set falling apart. This glue is also part of the Pro series by Rhino, guaranteeing top-notch quality. 

Rhino Glue, Heavy Duty 40 Gram Clear
  • The Only Glue You'll Ever Need!
  • Bonds in seconds plastics, vinyl, wood, rubber, metals,...

Why Did We Like It?

Right off the bat, what we liked about this glue was its fast drying time. Notably, the drying time is exceedingly swift compared to other permanent glues. Rhino categorizes this product as a tough-instant glue, and it does live up to the claims. So, while using this product, you wouldn’t need to wait for hours as the glue cures within 20 minutes. 

Moreover, the Rhino glue dries completely clear. Hence, there’s no need to worry about needing to paint over the adhesive to match the color of the Legos. And, as applying a few drops does the job, your Lego bricks won’t have a thick layer of glue between them. 

Furthermore, one of the critical features of this glue has to be the unique formula that makes it stronger than other glues. Because it’s a maximum-strength adhesive, your Lego bricks will remain glued together permanently. Plus, the glue has been toughened to make it shock-resistant and maintain a strong bond under pressure.

What Could’ve Been Better? 

When it comes to this glue, the only drawback we found was its strong smell. It can be a bit overwhelming for people who may be averse to the smell of adhesives. So, we recommend wearing a proper mask while using this glue to keep yourself from inhaling it. 

Pros
  • Strong bond
  • Easy application method
  • Dries rapidly
  • Shock-resistant
Cons
  • Strong smell

5. Krazy Glue

If you didn’t know already, Krazy Glue comes from the house of Elmer’s, so we were really thrilled about trying this product. And, this super glue didn’t fail our expectations when it comes to gluing together Lego bricks, as it does the job quite smoothly. So, let’s learn a bit about its features. 

Why Did We Like It?

Are you tired of using super glues that seem to lose their bond over time? Don’t worry, as Krazy Glue has got you covered. The strong all-purpose bond of this glue helps to keep the blocks attached even after a long time has passed. So, your Lego piece wouldn’t suddenly crumble apart after a few weeks after you accomplish the whole building process. 

Having said that, for us, the best feature of the Krazy Glue was the applicator which is perfect for attaching Legos, particularly the tiny pieces. The precision tip places a small dab that’s enough to give a strong bond. And, as the tube is compact, the application process is pretty smooth.

On top of that, the glue comes in a stay-fresh container, so it remains viable for multiple uses. However, do make sure to cap it properly after every use. 

51tcPhVdwXL. SL500

What Could’ve Been Better? 

To be honest, this is one of the best glues for Legos that we have tried out. However, our only complaint is that the individual packs have very little product. So, you’ll certainly need to buy more than one tube of the Krazy Glue for a bigger Lego art piece. 

Pros
  • Straightforward application
  • Strong adhesive
  • Compact-sized tube
  • Doesn’t dry out after single use
Cons
  • Less quantity

6. Le-Glue Temporary Glue 

Did you know that a kid made the Le-Glue non-permanent glue? Yes, this product was designed by Tripp Phillips when he was in the third grade. Unlike the other Lego glues mentioned by us, this one can be safely used by kids to create their fun Lego projects. So, let’s check it out. 

Le Glue Temporary Glue – Non-Permanent Adhesive for...
  • No More Messy Breakups – Enjoy your building masterpieces...
  • Design and Build Like a Pro – Our patented formula makes...

Why Did We Like It?

First of all, let’s focus on the use of the Le-Glue temporary glue. As you can understand, this glue is meant to bond the Legos temporarily. But, that doesn’t mean your blocks will fall apart, as this glue from Le-Glue has a hold that’s twelve times stronger than other temporary glues. 

Moreover, it works for all kinds of building blocks, including Lego, Nano Blocks, and Mega Blocks. You just need to apply a small dab of this temporary glue on one block and press the other block on it for some time to get a reliable bond. 

Furthermore, Le-Glue temporary glue comes in a non-toxic and solvent-free formula. And, it’s made from all-natural ingredients. So, your kids can safely play with it for as long as they want without facing any health issues. 

Plus, it’s pretty easy to break the bond of the Le-Glue temporary glue as all you need to do is soak the blocks or project in warm water.

What Could’ve Been Better? 

One of the only problems with this product is that the application can quickly get messy, especially for kids. As this glue comes in plastic packaging, you need to pour it into a container before starting your project. However, the good thing is that it’s easy to get rid of this glue from your clothes or skin, and it doesn’t leave any residue. 

Pros
  • Easy to use
  • Cures within 24 hours
  • Safe for use by kids
  • Dissolving glue is hassle-free
Cons
  • Application can get messy

7. BrickShield

Have you been looking for a semi-permanent glue that’s easy to apply? If so, then check out this non-toxic and kid’s safe glue from BrickShield that has been designed specifically for Legos. It comes in a handy spray bottle that lets you apply the glue directly on the bricks without needing any applicator. 

BrickShield Plastic Brick Glue Spray - Temporary Glue for...
  • TEMPORARY SPRAY ADHESIVE - BrickShield spray safely bonds...
  • EASILY REMOVABLE - Whenever you are ready to un-bond your...

Why Did We Like It?

Straight away, what we liked about this product was the packaging which makes applying the glue pretty easy. Do follow the directions specified by the brand, and you’ll be able to glue Legos with precision. A nice thing about the bottle is that the kids face no problems in spraying, and it doesn’t hurt their hands. 

Moreover, this glue has been specially designed for plastic blocks of all kinds, including Lego. And, it drastically reduces the time needed to glue Legos for elaborate projects because of fast application. 

Another one of the key features of this temporary brick glue is its non-toxic and kid-safe formula. This is rarely seen in aerosol products made for kids, so we were pretty impressed with this adhesive

Plus, the brand provides a 100% satisfaction guarantee with this spray glue. So, if, for some reason, you’re not happy with this product, there’s an option to contact customer care to receive a refund. 

What Could’ve Been Better? 

We would like you to know that this isn’t really a drawback that’s exclusive to this glue as it’s common in all spray glue products. When you spray to apply the glue from a distance, there’s bound to be some wastage. This means that it’s always better to keep a backup of this glue to avoid running out of it. 

Pros
  • Ease of application
  • Dries and cures quickly
  • Glue washes off easily with soap water
  • Dissolves in warm water
Cons
  • Does have wastage

Glue For Legos Buying Guide

Glue For Legos Buying Guide 

When choosing the best glue for Legos, you need to know some essential points that’ll help to make the right decision. As gluing the Legos is often based on specific projects, skipping any points may leave you with completely unusable glue. So, let’s check out these key points. 

1. Viscosity

One of the most important features to look for in glue is its viscosity. A thin consistency may prove to be challenging while gluing Legos as it may cause the blocks to slide around. Hence, it’s better to opt for glue with thick viscosity or a gel texture for attaching the Legos easily. 

Moreover, thicker glues are easier to apply on vertical surfaces. As Lego projects can have a mix of vertical and horizontal planes, opting for glues with thick viscosity proves to be an excellent choice. And it makes the process less messy. 

2. Permanence 

Would you like the Lego set to have a permanent bond? If so, it’s best to choose a glue that comes with the capacity to bond the surfaces permanently. While choosing a permanent glue, make sure to handle your Lego construction properly before it cures properly. 

However, while researching about the glue for Legos, we found out that some people prefer semi-permanent or non-permanent glue. These options are better to display the completed project for a certain period. It also leaves you with the choice to dismantle the Lego structure whenever needed. 

On that note, while choosing a non-permanent or temporary adhesive, don’t forget to check the process of breaking the bonds. Typically, the glues are water-soluble and dissolve in warm water, but some may require the application of certain chemicals to come off the Legos entirely. 

3. Curing Time 

Another point to check while looking for the best glue for Legos is the curing time. As you may know, there’s a wait time for most glues when it comes to handling the pieces after attaching them. In the case of Legos, we want it to be as fast as possible to avoid detaching the pieces. 

Now, the cure time or the total time taken for the glue to dry is usually between 24-48 hours, depending on the brand and consistency of the adhesives. Superglues take the least time, while white glue takes the longest. So, make sure not to forget about the curing time while ordering your Lego glue. 

4. Ease Of Application 

On searching how to glue Legos, a common suggestion you’ll notice tells you to look for the suitable glue. And, that’s why it’s important to choose a Lego glue that comes with ease of application. 

You don’t want it to be too messy, as it can make working with small blocks frustrating. At the same time, try to find a product with a precise applicator to avoid using too much glue. 

Having said that, the application technique does vary depending on the project, so try to find a product that fits your demands from the adhesive.

Best Glue For Legos

Verdict

So, that’s everything we had to tell you about buying the best glue for Legos from the available options on the market. If you have any doubts while picking a product, don’t hesitate to go through the buying guide for a recap of some key features. 

Among our recommendations, we will suggest the Gorilla ‎super glue to anyone looking for an adhesive with a thick formula and long-lasting bond. 

On the other hand, the Loctite ‎super glue takes the cake for the fastest drying time without the need for clamping down the Legos. Just make sure to clean the tip after every use to prevent clogging. 

With that, we come to the end of this guide. We hope that you will find the best glue for your Lego creations among our suggestions. Until next time!
