Best Way to Glue Legos Together: Tips & Tricks

best glue for legos

There are a variety of glue options available for LEGO enthusiasts, including LEGO glue, adhesive, epoxy, and repair glue. Each has its own unique properties and benefits, and it can be difficult to know which one to choose. In this article, we will explore the factors to consider when choosing LEGO glue, provide you with top recommendations for the best glue for LEGOs, and offer tips on how to apply it for the best results.

Factors to Consider When Choosing LEGO Glue

When looking for the best glue for LEGOs, there are several factors to consider for optimal results. The right glue should provide a strong and durable bond, be compatible with LEGO plastic, and be easy to use. Here are some specific characteristics to look for:

  1. Strength and Durability: The glue should be strong enough to hold the LEGO pieces together securely, even under stress or pressure. It should also be durable enough to withstand wear and tear, and not break down over time
  2. Compatibility with LEGO Plastic: Not all glues are suitable for use on LEGO plastic. Make sure the glue you choose is specifically designed for use on this material, and won’t cause any damage or discoloration
  3. Ease of Use: Applying glue to small LEGO pieces can be tedious, so it’s important to choose a glue that is easy to use and apply. Look for a glue with a fine applicator tip or brush, or one that comes in a spray or aerosol form for easy coverage
  4. Non-Toxicity: If you’re working with children or have concerns about toxic chemicals, look for a glue that is non-toxic and safe for use around kids
  5. Clear Drying: The glue should dry clear and not leave any visible residue or discoloration on the LEGO pieces
  6. Resistance to Moisture: LEGO creations can be exposed to moisture, so it’s important to choose a glue that is resistant to water and won’t break down or dissolve when wet

How to Apply LEGO Glue for the Best Results

Once you have chosen the right glue for your LEGO project, it’s crucial to follow some steps to ensure the best results. Here are the steps to follow to apply LEGO glue:

  1. Clean the area of your LEGO creation that needs gluing. Use a cloth to wipe it down and remove any dirt to ensure a strong bond
  2. Take a small amount of glue and apply it to the surface of your LEGO piece. Too much glue can make things look messy and take longer to dry. Use a toothpick or a small paintbrush to spread the glue evenly
  3. Carefully join the pieces together. Ensure that they are aligned correctly and apply some pressure to bond them securely. Do not move the pieces to avoid a weak bond. You can use clamps or masking tape to hold them in place while the glue dries
  4. Allow the glue to dry for the recommended time. Most glues suitable for LEGO require 24 hours to cure completely

Alternative Options to Glue for LEGO Bonding

While glue is an effective method for bonding LEGOs, there are alternative techniques that can be used as well. These methods can offer unique advantages or limitations, depending on the specific situation and preference of the builder.

Interlocking Bricks

One popular technique is to interlock LEGO bricks together without the use of glue. This method relies on the precise fitting of the bricks to create a secure bond. Advantages of using this technique include the ability to easily disassemble and reassemble the structure, as well as the flexibility in creating a variety of shapes and designs. However, it may not be suitable for larger or more complex structures that require more stability.

LEGO Connectors

Another option is to use LEGO connectors, such as pins or axles, to join LEGO pieces together. These pieces can offer a more reliable connection than interlocking bricks alone, while still allowing for easy disassembly. This method is particularly useful for building moving parts, such as gears or joints. However, it may not work as well for larger structures or those that require a more solid connection.

Specialized Clips

LEGO also offers specialized clips that can be used to join pieces together, such as Technic pins or LEGO hinges. These pieces can provide a strong and stable connection, while also allowing for movement and adjustment. They are particularly useful for building vehicles or structures with moving parts. However, they may not be as versatile as interlocking bricks or suitable for all types of structures.

Ultimately, the choice of bonding technique will depend on the specific needs and preferences of the builder. While glue is a popular and an effective option, there are alternative methods available that can offer unique advantages and limitations.


Our top recommendations for the best way to glue LEGOs together include construction adhesives and bonding glues from reputable brands. When applying the glue, following the correct process is essential for the best results, including preparing the surface, applying the glue, and observing curing or drying times. Alternative bonding techniques such as interlocking bricks or using LEGO connectors may also be viable options to consider.
