1. TOPELEK – Best Hot Glue Gun For Styrofoam

Best Glue For Styrofoam - Reviews & Buyer's Guide

Next up we have this hot glue gun and he was from Amazon. It was kind of a random purchase. I’ve never heard of them before.
But it actually came with a bunch of glue sticks in the box, so you get more value for your money.

Good Random Purchase?

I plugged it in and it honestly took like a minute to heat up, so little random Amazon purchase is off to a really good start, so let’s put him through the test.

Squeeze ability

It comes out pretty. Well. It’s just very like, you know what it works. I was gonna complain about something, but really (!) it works.

So I’d say four stars next we’re gonna see the dry time on this one since it heat it up so quick.

I don’t know what that means for how quickly it’s gonna dry, but we’re gonna find out. Okay, let’s check dry time.  It’s dry 2 minutes and 15 seconds. That’s pretty good pretty good dang.

The flow is not really good but this hot glue for styrofoam can work with this kind of surface. The cord here has this little protection that kind of makes it turn easier.

And I think these things make your cord last longer that they don’t get broken or damaged as easily. Which is great it might last a little bit longer and something else.

Verdict

It doesn’t really relate to the cord at all, but it has an on and off switch which is so good because we are are always like unplugging and re-plugging in our glue gun which I feel isn’t great.

Best Glue For Styrofoam – Buyer’s Guide

Types of Glue for Styrofoam

Depending on variables such as the materials you want to bind together, the level of resistance you require the final product to have and various others, you will have to choose a type of glue that is suitable. The following are some of the most common types of glue for styrofoam:

Basic Craft Glue

If you are looking to create a simple and casual arts and crafts project involving styrofoam, the best option is often to use white glue. Despite being very affordable and commonplace, this type of glue works reasonably well for attaching styrofoam parts together. Even better, it works well for attaching pieces of styrofoam to other materials you may use when making a base for a diorama, including wood, cardboard and paper.

Now, there are two main types of basic craft glue. The first is white school glue. This type of glue is characterized for being safe, non-toxic and child-friendly. It is also very affordable. However, it tends to be runny and messy. What’s worse, it tends to be a great deal less durable than other types of glue.

The second type of basic craft glue is the white tacky glue. This is a lot like the white school glue but thicker and tougher. Despite being very affordable, this type of white glue can be used with various materials apart from styrofoam, including paper, cardboard, wood and some types of plastic. In addition, it can be used in various applications ranging from basic art projects to advanced modeling projects.

Styroglue

There is a type of glue that was specifically developed in order to be used with styrofoam. This type of glue is often referred to as “Styroglue”. It tends to be affordable and practical. However, it can be difficult to find, at least in comparison with regular white school glue. Then again, most home improvement or arts and crafts stores tend to carry it.

If you are going to try this type of glue, be sure to read its instructions. Some brands are specifically formulated to work on styrofoam and, as such, they will not help you attach styrofoam to other materials. Other brands, though, are specifically formulated to bind styrofoam to other materials. If you are looking to create a solid diorama base with a wood bottom, you may want to look at this type of glue.

Spray Adhesive

Spray adhesives offer a quick, practical and convenient manner to glue different pieces of styrofoam together. What is more, many of them can actually bind styrofoam to other materials, including wood, cardboard, paper and some types of plastic. More impressively, some spray adhesives are capable of bonding styrofoam to metal. For that reason, many experienced diorama enthusiasts use spray adhesive to create realistic details on their projects.

If you are using spray adhesive, try testing the product on a small area first. Additionally, take into account that some aerosol-based products are capable of dissolving, melting or otherwise damaging styrofoam. With that in mind, it’s always wise to try a new product on a small piece of styrofoam that would otherwise be discarded.

Spray adhesives tend to be low-tack. For that reason, they are best used when attaching large pieces of styrofoam together. If you are attempting to bind together two pieces of styrofoam by a small contact area, however, this type of adhesive may not be such a good idea. For example, it wouldn’t be effective at attaching to styrofoam balls together.

Low-Temperature Glue Gun

To be sure, hot glue guns are capable of attaching styrofoam to different types of surfaces often used in arts and crafts, including paper, cardboard, wood and others. However, heat can actually damage styrofoam after coming in contact with it, resulting in accidental deformations and other problems.

Even worse, the contact between styrofoam and hot glue can result in harmful fumes being released. For that reason, it is always better to use a low-temperature hot glue gun when working with styrofoam.

There are some clear advantages to using a low-temperature glue gun on styrofoam. For one, they are fantastic at attaching small styrofoam objects together. They are also great at attaching large styrofoam objects by small contact surfaces. Going back to an earlier example, this type of glue is very effective at attaching styrofoam balls together.

Types of Glue You Should Never Use With Styrofoam

There are some types of glue that can be completely ineffective when dealing with styrofoam. Worse yet, there are types of glue that can damage the material. The two main ones are the following:

Material Specific Glue

Be aware: When gluing styrofoam, it is necessary to avoid all glues that are specifically formulated to bond with materials other than styrofoam (for example, fabric glue, wood glue, concrete glue, etcetera).

Even though some of this glues may work on styrofoam, they are not likely to work on it any better than regular white craft glue. However, material-specific glues are a lot more expensive than regular white glue, making them an inefficient use of your money. In the worst case scenario, however, the wrong kind of glue can damage and even dissolve styrofoam.

Glue That Contains Plastic Solvents

Because it is so flimsy and light, many people forget that styrofoam is a form of plastic. Essentially, the material is “foamed” plastic, meaning that it has been mixed with air, resulting in an airier product.

Being a plastic product, styrofoam is not resistant to glues that contain solvents that are capable of dissolving plastic. Logically, using these products may result in damage to your styrofoam with the potential or ruining your diorama project. As a matter of fact, some glues are so potent that can completely melt down styrofoam.

In particular, you should watch out for glues that contain alcohol and acetone. For example, rubber cement, a type of glue that contains both the previously mentioned substances, can completely dissolve styrofoam within minutes. However, there are rubber cement glues that do not contain acetone or alcohol, making them suitable for use on styrofoam.

Conclusion

Without a doubt, having the right glue for styrofoam can greatly facilitate the making of a stable and durable base for a diorama. All the products featured in this article have notable characteristics that make them good options for being used on styrofoam. Hopefully, this buyer’s guide will help you choose the perfect glue for styrofoam for your particular needs.
