On paper, glue appears to be a simple material, but it’s far from that. Glue is a nonmetallic substance used as a holding agent between two objects. Almost anything can be used to make it, and the word can refer to many different kinds of substances. Since adhering to the plastic of your Legos is very important, it is important that you know what type of glue you are buying.

Types of Lego Glue

Multiple glue types exist, and each one has its own characteristics and properties. The use of rock, stone, or plastic on nonporous surfaces is necessary for other materials. Some of the types you will find are:

• Craft
• Wood
• Cyanoacrylate adhesives (Super)
• Fabric
• Polyurethane

Polyurethane and super glue are the best ones for Legos. In terms of both brittleness and bonding to nonporous materials, these types are well-suited. It is very important that craft materials, wood, and fabric are placed on a porous material if they are to work properly.

The method of application

People who attended elementary school know there are several types of glue. Some come in liquid form, some in gel form, and some come in sticks. You want a liquid or gel with a narrow tip when you are gluing Legos together. This allows you to determine how much substance is on the brick and where it lies.

The excess glue can drip out of the sides of two connected Legos if there is too much glue applied at any one time, which causes a huge mess.

Gluing Legos together

Legos are simple to assemble, but require precision to glue. You simply need the Legos of your choice and glue. Having your pattern selected in advance will allow you to carefully place the bricks.

Build your structure from the ground up. In order to glue the Legos together, you just need to dab a small amount of liquid glue onto Lego A and then gently press Lego B against it. 

Depending on the glue you’re using, you may need to hold the pieces together for five to fifteen seconds to seal them.

Your next piece can be started then. Don’t work too fast or you will make permanent errors.

Glue for Lego – FAQs

Is it a good idea to glue Legos together?

You are allowed to glue your Legos together even though Lego encourages buyers not to do so. If you want to keep your Legos together, then you must be sure that you do not want any kind of permanent seal from adhesives or that they will gradually deteriorate over time.

Once the Legos are put together, can you dissolve the glue?

It depends on the type of glue you use and whether it dissolves. Vinegar usually dissolves Krazy Glue, but Loctite and Gorilla Glue cannot. Choosing your glue carefully is therefore important.

Is wood glue suitable for gluing Legos?

Most wood glues contain polyvinyl acetate (PVA), which is a porous material that bonds exceptionally well to wood. The glue does not adhere well to nonporous materials, such as plastic. The result is that if you glue wood to Legos, your structure may break. Try one of the alternatives described above, instead of using wood glue.

Conclusion

A lot of it depends on what kind of Lego structure you are trying to build, how long it should last, and which glue or adhesive you are going to use. Because it will hold tight regardless of external conditions, Loctite Super Glue makes an excellent choice for permanent models. The Krazy Glue or another option on this list is a great option if you are looking for something temporary or semi-permanent.
