Epoxy Resin: The Ultimate Bonding Solution

Epoxy resin is a popular choice among Lego enthusiasts due to its exceptional strength and durability. This two-part adhesive consists of a resin and a hardener that, when mixed together, create a strong chemical bond. Epoxy resin provides a permanent solution, ensuring that your Lego creations stay intact for years to come.

One advantage of epoxy resin is its ability to bond different materials, including plastic, metal, and wood. This versatility makes it an excellent choice for Lego enthusiasts who want to incorporate various elements into their designs. Additionally, epoxy resin is resistant to water and temperature changes, making it suitable for both indoor and outdoor Lego displays.

However, it is important to note that epoxy resin requires careful handling and precise mixing ratios. Improper mixing can result in weak bonds or a sticky residue on the Lego bricks. Furthermore, once cured, epoxy resin is difficult to remove, so it is crucial to apply it with precision.

Cyanoacrylate (Super Glue): Quick and Strong

Cyanoacrylate, commonly known as super glue, is another popular option for securing Legos. This adhesive forms an instant bond when it comes into contact with moisture, making it ideal for quick fixes or small Lego projects.

Super glue is easy to use and dries quickly, allowing you to continue building without much interruption. It forms a strong bond between Lego bricks, ensuring that they stay firmly in place. However, it is worth noting that super glue may not be as durable as epoxy resin, especially when exposed to extreme conditions or heavy stress.

One drawback of using super glue on Legos is its irreversible nature. Once applied, it is challenging to remove without damaging the bricks. Therefore, it is essential to exercise caution and precision when using super glue on your Lego creations.

Polyvinyl Acetate (PVA) Glue: Versatile and Reversible

Polyvinyl Acetate (PVA) glue, commonly known as white glue or school glue, is a versatile adhesive that is widely available and easy to use. It is water-based and non-toxic, making it suitable for children and adults alike.

PVA glue provides a strong bond for Lego bricks, although it may not be as durable as epoxy resin or super glue. However, one significant advantage of PVA glue is its reversibility. Unlike epoxy resin or super glue, PVA glue can be softened and removed by soaking the Lego bricks in warm water. This allows for easy disassembly and reconfiguration of Lego creations.

While PVA glue is an excellent option for temporary or less demanding Lego projects, it may not be the best choice for long-term displays or structures exposed to frequent handling. It is important to consider the intended use of your Lego creation when selecting the appropriate glue.

BrickLink Glue: Designed Specifically for Legos

BrickLink Glue is a specialized adhesive formulated specifically for Lego bricks. Developed in collaboration with the Lego community, this glue aims to provide a balance between strength and reversibility.

BrickLink Glue offers a strong bond while still allowing for disassembly if needed. It is designed to be compatible with Lego bricks, ensuring that it does not damage or discolor them. This adhesive is available in different viscosities, allowing users to choose the consistency that best suits their needs.

One advantage of BrickLink Glue is its user-friendly application. It comes with a brush applicator, making it easy to apply the glue precisely to the desired areas. Additionally, it dries clear, leaving no visible residue on the Lego bricks.


When it comes to securing your Lego creations, choosing the right glue is essential. Epoxy resin provides unmatched strength and durability, while super glue offers quick and strong bonding. PVA glue offers versatility and reversibility, while BrickLink Glue is specifically designed for Lego enthusiasts. Consider the specific requirements of your Lego project and select the glue that best suits your needs. With the right adhesive, you can ensure that your Lego creations stay intact and bring joy for years to come.
