Glue is a unique material and not as simple as it sounds on paper. The word can refer to any nonmetallic substance used to hold two objects together, and it can be made of just about anything. This is why it’s important to know what type of glue you are buying and how well it will adhere to the plastic of your Legos.
Types of Glue for Lego
There are multiple types of glue available, and each one has its own properties and characteristics. Some work well on porous materials, while others need to be used on nonporous items like rock, stone, or plastic. The varieties you will encounter include:
- Craft
- Wood
- Super (cyanoacrylate adhesives)
- Fabric
- Polyurethane
Out of these types, the best ones for Legos are super glue and polyurethane. These types are brittle and adhere well to nonporous substances. Options like craft, wood, and fabric need to be placed on a porous material to work well.
Application Method
Anyone who has gone to elementary school knows there are multiple forms of glue. Some are liquids, some are gels, and a few come in sticks. When you are trying to glue Legos together, you want to stick with a liquid or gel that has a narrow tip. This allows you to control where the substance lays and how much is on the brick.
Using too much glue at any given time can result in the excess dripping out the sides of two connected Legos, which makes huge mess.
How to Glue Legos Together
The process of gluing Legos is simple but requires precision. All you need are the Legos you desire and the glue of your choice. It is a good idea to have your pattern or structure chosen beforehand so you can carefully place the bricks together.
To begin, start with the base of your structure. To glue the Legos together, all you need to do is apply a small dab of liquid glue on Lego A and then carefully press Lego B to it. Depending on the type of glue you have, you will need to hold the pieces together for 5 to 15 seconds until the seal is tight.
You can then move on to your next pieces. Avoid working quickly because you will be more prone to permanent mistakes.
