Factors to Consider When Buying Glue for Lego

When buying glue for Lego, there are several things that you should take into account. Here are four of the most important factors to keep in mind:

Type of Lego You’ll Be Gluing.

One of the most important factors to keep in mind when buying glues for legos is how strong you need them to be. As mentioned above, there are two major types of glues: super glue and epoxy. The stronger the glue is, the longer it will hold together your creations. In some cases, this may even be an issue for parents who want to give their children safe toys but don’t want them breaking quickly.


You should also consider how many bricks you’ll be gluing at once. If you’re working on a small Lego toy that requires only a few bricks to construct, this won’t be an issue. However, you should keep in mind that the more bricks you have to put together, the greater chance there is that your creation will fall apart.

Type of Lego You’re Repairing

Another factor to keep in mind has to do with the type of brick you’re trying to adhere back together. This could mean looking into different glues if it’s a newer construction and glue won’t stick well or if it’s an older set and glue will cause damage to it.


Newer construction Lego bricks contain different materials. The glue will stick well to this type of Lego, but if you’re repairing a vintage or decaying brick with old and crumbling material, you may want to opt for epoxy glue instead of superglue because it’s a harder material.

Heat and Cold Conditions

It is also important to know whether you will be working on your creations in cold temperatures or heat conditions. For example, the super glue can actually lose its adhesiveness in cold weather if it’s exposed to freezing temps for extended periods of time. However, it can also become stronger due to the same conditions while remaining indoors. The same is true of heat.


You should also know that super glue will become more viscid or runny in hot conditions. This means that the moisture content of the air can affect its quality. Be sure to keep these factors in mind and to test your creation before using it since you don’t want it to fall apart or warp at a crucial moment.


Most Popular Lego Gluing Methods

You should also be aware that there are two common gluing Lego methods together: the first is known as “dry fit,” while the second is referred to as “wet fit.”


Dry Fit Often Used for Repairing Sets or Customizing Pieces

When people talk about dry fit, they usually refer to when one or more models are assembled prior to gluing them on a surface for play or display. Dry fit is a common way to assemble Lego sets before they’re put on display, and it helps to avoid having the pieces come apart due to friction and shifting.


This type of fit is also useful when trying to customize different pieces for a custom-made creation. For example, you can use dry fit to determine the best way to arrange different pieces together before you achieve the final look you want.


Wet Fit Often Used for Repairs and Restorations of Sets

On the other hand, wet fit refers to gluing Lego bricks together after they’ve already been assembled. This is often used to repair or restore sets, but it can also be used in the same manner as dry fit.


Wet fit is also referred to as “rescue” or “making good.” For example, when you have an older set that’s falling apart, and you want to fix it, you’ll use wet fit to attach the pieces back together.


Frequently Asked Questions about Glue for Lego

Finding the best Lego glue is a matter of knowing where to look for it. The most convenient place to find the glue you’re looking for is online. You’ll find that several websites like Amazon offer the glue you need at a reasonable price.

The strongest Lego glue would have to be the Loctite Ultra Gel Control Super Glue. This glue won’t break easily at all, so you can rest easy knowing that your creations will stay intact and won’t be easily broken.

When it comes time to repair your Lego sets, you should first clean the area that needs fixing with rubbing alcohol or glass cleaner. After you’ve cleaned the area, apply a drop of glue on the surface and hold it there until it dries.

This depends on the type of glue you use. For example, Loctite glue will dry in about 30 seconds. However, other glues may take up to a few minutes to dry. It’s important to know how long a glue takes to dry before you’re applying it, so you can let the glue dry and then test it before using it again.
