Thick or Thin? Choosing the Best Super Glue for Miniatures

Assembling miniatures and model kits is a skill many take for granted, myself included. It seems simple from the surface, just put pieces together and you’re done, right? Well, not exactly. One of the most important parts of constructing miniatures is choosing the right adhesive to hold everything together. Super glue or cyanoacrylate is especially popular among miniature hobbyists, model makers, wargamers, and the ever-passionate gunpla enthusiasts. We love super glue because of its quick-drying, strong and durable bond. However, not all super glues are created equal.

In this article, I take a closer look at its three main types—thin, medium, and thick viscosity super glues. Each type offers unique advantages for different aspects of assembly and type of modeling task. I’ll also go into a few limitations with tips and tricks to overcome them.

Key Takeaway (Tl;Dr)

  • Cyanoacrylate in super glue forms quick bonds but allows little room for adjustments; viscosity is a crucial factor for selection.
  • Low-viscosity glues like CYAPRO work well for small, detailed components but can be messy and less durable.
  • High-viscosity glues such as GlueMasters are optimal for larger, heavy-duty pieces, and notorious for their usefulness in attaching magnets to tabletop wargaming miniatures; more control, slower cure time.
  • Medium-viscosity options like Gorilla Super Glue offer a balanced but non-specialized approach to bonding speed and strength.
  • Choice of super glue should be based on specific project needs, including control and time for adjustments.

Read on to learn more about what I discovered about the different kinds of superglue and the best use for each type in miniature and model hobbies.

The Basics of Cyanoacrylate

What is cyanoacrylate glue?

Cyanoacrylate (aka super glue) is a cyano-based group of polymers known for its strong adhesive properties. When applied to a surface, the liquid monomer reacts with water vapor in the air and begins polymerization, forming long chains of molecules that bond surfaces together. This makes super glue an excellent choice for bonding materials like plastic, metal, and even wood (source).

Water: The Unsung Hero in Cyanoacrylate

Contrary to what you might think, water plays a vital role in the functioning of superglue. Yeah, you read that right. The water. The very thing we often strive to keep away from our model sets. But without it, our favorite cyanoacrylate wouldn’t be quite so… super.

Here’s how it works: Cyanoacrylate is an acrylic resin that rapidly polymerizes in the presence of water (source). This means that when you apply super glue to a surface, it’s not the air that triggers the bonding process. It’s the water vapor present in the air. This water vapor initiates a reaction that forms tight molecular chains, bonding the surfaces together almost instantly.

This is the reason why superglue bonds so well to your skin. Our skin’s surface is never completely dry, making it an easy target for superglue. A pro tip I’ve used on numerous occasions to remove pesky super glue from my fingers is to wipe my hands with nail polish remover which contains acetone.

Superglue loves water and will use any residual moisture to cure/bond to a surface.

The acetone will break down the polymer chains, loosening the bond and allowing you to peel off any excess glue. But don’t worry, it’s safe for your skin in small amounts!

Another helpful tip: You’ll find acetone is helpful for other hobby tasks, such as cleaning off your tools and the residue build-up in your airbrush (use a tiny dab on a cotton tipped applicator to apply acetone/nail polish remover).

The Pros and Cons of Rapid Curing Superglue

How does rapid curing influence the effectiveness of super glue?

One of the standout features of super glue is its rapid curing time. This means it dries and sets extremely quickly, which can be a major plus when you’re working on a project and you just can’t wait for things to dry. For miniature builders, this is a godsend, allowing rapid progress in assembly and fewer delays in completing the project.

Pro tip: Do you have a clogged metal superglue nozzle? You can use the heat from a lighter to burn away dried glue inside a clogged metallic superglue dispensing tip.

However, like any other feature, rapid curing has its downsides too. Speedy drying times don’t always allow for adjustments or repositioning once the glue is applied. If you make a mistake or if the pieces are not aligned properly, fixing the issue can be a challenge. Furthermore, the glue can dry out and become unusable if not stored properly. It is also worth noting that while rapid curing is beneficial in a dry environment, high humidity can lead to premature curing before the glue is even out of the bottle.

Here’s a quick table to further illustrate the pros and cons of rapid curing in super glues:

Rapid curing allows for quicker progress in assemblyMistakes or misalignment are hard to fix due to fast drying
Fewer delays in completing the projectCan dry out in the nozzle and become unusable if not stored properly (e.g, replace the cap/cover quickly)
Beneficial and easier to use in dry environmentsHigh humidity can lead to premature curing

Super Glue viscosity: how does it matter?

Viscosity, measured in centipoise (cp), refers to a liquid’s resistance to flow or, in simpler terms, its ‘thickness’ (source). Think of water (low viscosity) versus honey (high viscosity). Now, when it comes to superglues, the viscosity level plays a significant role in determining its application and performance.

Thin super glues, typically under 5cp, flow readily, almost like water. They’re perfect for seeping into small cracks, bonding tightly-fitted parts, or wicking into porous materials. However, they set fast, sometimes in just a few seconds, which doesn’t leave you much time for adjustments.

Medium viscosity super glues, ranging from 100-150cp, give you a bit more control during application and slightly longer set times. They fill small gaps efficiently and are suitable for parts that need a bit of positioning before the bond sets.

Thick super glues, usually over 1500cp, are gel-like and allow ample time for adjustments before they set. They excel in filling larger gaps and bonding irregular or uneven surfaces.

Gorilla Super Glue

Thick or thin superglue for miniatures? Best superglue for miniatures models - Gorilla super glue packaging produc photo on white background
A popular and versatile super glue.

It’s not as thick or thin as the other two superglues that I’ve noted above. But, Gorilla Super Glue is one of the most popular cyanoacrylate adhesives you’ll find in the miniature and modeling hobby space. This is for good reason: You can find this brand of super glue in almost any local hardware store. It’s also in many popular brick and mortar arts and crafts stores, too, e.g., Hobby Lobby, Michaels.

Gorilla glue is an all-purpose adhesive that I’ve used for years for various things. Though not my go-to super glue for miniature hobby things, due in part to it’s wide nozzle size which is cumbersome for applying on small surfaces, I prefer the thick viscosity glues for most projects (see Gluemasters and shown above). For non-hobby projects, Gorilla Super Glue does have versatility across many other needs you may have around the home or work. It sets quickly (under 45 seconds) and bonds to almost any material you can imagine.

Other Useful Information About Superglues

When you’re painting miniatures or building scale models, super glue isn’t just for sticking two pieces together. Here’s a quick overview on what else you should think about when using it.

I’ve assembled a lot of models with super glue. This isn’t even a fraction…

Safety Precautions

Superglue releases fumes before and after the curing process has begun. The vapors are even more volatile when the ambient air temperature is warm (above 60℉ or 16℃). Both the stinging sensation in your nostrils or the tears from your eyes are signs you should probably find better ventilation when working with superglue. While I don’t use gloves, it is often a recommended idea to do so if you want to avoid accidently bonding your fingers together.

Surface Preparation: Stronger, More Reliable Bonds

The readiness of your workpieces directly influences the efficacy of the adhesive. A clean surface is imperative; remove all traces of dirt, oil, and other contaminants before application. For certain materials, a light sanding could improve the adhesive contact, offering increased grip.

Activators and Accelerators: Use Wisely

The use of activators or accelerators can be advantageous (source). These substances expedite the super glue’s curing process, enabling you to proceed to the next phase of your project more quickly.

A super glue accelerant will vastly speed up the cure time. However, too much will make the bond fragile. Use sparingly.

When you’re a gaming convention, for example, you may need to perform rapid repairs on tabletop miniatures. Zip kicker or other catalyst can make the job go much quicker with less mess.

However, exercise caution; excessive use of catalysts can compromise the integrity of the bond, making your superglue bonds more susceptible to fractures.

Proper Storage: Safeguarding Usability and Saves You Money

Always cap/cover your superglue bottles when you’re not using them! Effective storage will prolong the lifespan of your super glue. If you’ve been in the hobby for a while, then you may have noticed that your super glues tend to lose their initial curing speed.

Cap your glues! Even when the cap breaks, keep air exposure to a minimum.

That bit of excess air exposure over time allows the super glue to lose some of its fast-curing properties. At this point, you may need to use that activator/catalyst to speed up the dry time again. To reduce this degradation of your superglues, store as instructed.

Fine Application Techniques

The art of applying super glue involves a delicate balance. I won’t go into much detail here about how I apply superglue to models. However, I will mention that I use a toothpick or a super glue looper applicator to precisely apply super glue on small, delicate surfaces.

Thick or thin superglue for miniatures? Best superglue for miniatures models - glue looper product photo front
The Glue Looper is one of the best recent hobby purchases I’ve made.

The glue looper in particular is an amazing tool for careful glue application on super narrow, thin edges. Because super glue dries so quickly, every second counts especially with small bits you’re trying to glue together. You’ll have to move quick, so there is often some skill-up time required to be effective with assembling miniatures efficiently with superglues.

My Glue Looper has traveled to so many places over the years.

Note that “less is usually more” with superglues. Over-application can lead to an messy finish and extend curing times; whereas insufficient amounts risk a weaker bond.

Final Thoughts

In the art of assembling miniatures, the choice of super glue can significantly affect both the quality and durability of your work. The market offers cyanoacrylate adhesives in various viscosities: thin, medium, and thick. Each has its own set of advantages and drawbacks tailored for specific tasks. Thin super glues dry quickly and are excellent for precision but lack in strength and gap-filling capabilities. Thick glues offer robustness and better control but require a longer setting time. Medium-viscosity glues provide a balanced option suitable for a range of applications.

Safety measures and surface preparation are also crucial factors. Wearing protective gear and working in a well-ventilated area are essential for anyone engaged in this hobby.

When selecting a super glue for your miniature project, consider both your immediate requirements and the particularities of your work. Making an informed choice can make a marked difference in the end result.
