Epoxy

Epoxies are glues that result from epoxy resin after processing it into a functional product. There are a lot of different epoxies out there and some are entirely not suitable for styrofoam usage and will cause an exothermic reaction resulting in the styrofoam block melting. That being said, epoxies are fantastic for creating lasting, permanent bonds due to the cured nature of the final bond.

Two-Part Acrylic Adhesives

Two-part acrylic adhesives work wonderfully to bond styrofoam without breaking down the material or degrading its integrity. These can either require time to cure or need UV exposure to fully bond. Most of the time, the resulting bond is very clear and will not yellow with time, making it suitable for visible adhesion locations.

Silicone-Based Flexible Glues

Silicone-based glues provide flexible adhesion for areas that may regularly contact other surfaces and need a little give. They provide strong adhesion but may not be suitable for spaces that will endure a lot of wear and tear.

Cyanoacrylate (Super Glue)

Cyanoacrylate is an acrylic resin that creates an incredibly strong, instant bond that is lasting and often permanent. It uses water in the air to form into a type of mesh; if there is not enough water in the air, it is not as effective. Still, in most climates it works perfectly to quickly bond two surfaces together, including styrofoam.

How to Glue Styrofoam

Gluing styrofoam to other surfaces or even other pieces of styrofoam is not a complicated process. First, you must select an appropriate glue type that is suitable for creating a bond on the surface without melting the material. Then, you simply dry the surface of the foam and apply it as evenly as you can, per the directions on the packaging. Let it dry or cure as the directions dictate and you should be all set!

Safety Precautions

The biggest concern when using styrofoam is to always be aware if it is melting. Melting styrofoam can become liquidy and get onto the skin, causing burns or irritation. Also, when melting or otherwise exposed to heat, styrofoam can release carbon monoxide which is potentially toxic. The pieces that make up styrofoam can also pose choking hazards to small children, as well.

Glue for Styrofoam FAQ

Choosing a styrofoam glue that will allow you to stick together foam in all its many shapes and sizes can be tricky. You may also want a glue that works on materials other than styrofoam. And with a decent glue, you can make just about any styrofoam creation come to life. Below, you’ll find a table that can help you find the stickiest glue for your craft projects.

Here are a few frequently asked questions regarding types of glue for styrofoam.

How to glue styrofoam together with adhesives?

To glue styrofoam together, all you’ll need is an adhesive that bonds styrofoam without melting it too much. With your glue, add adhesive to both parts of the styrofoam you intend to bond. After you evenly coat the two pieces with adhesive, bring the parts together and let dry.

What type of glue can you use on styrofoam?

The best type of glue for styrofoam is a polystyrene glue. This type of glue bonds well to the styrofoam, since they are of the same material. If you don’t want to wait too long for the glue to dry, then the best adhesive for styrofoam is cyanoacrylate.

What sticks to styrofoam?

The best adhesives for gluing styrofoam together are ones that work with this material. All-purpose adhesives will work on bonding other materials to styrofoam. If you intend on adhering rubber to styrofoam, then you’ll need to look for an adhesive that bonds with both rubber and polyethylene.

On average, how long does styrofoam adhesives take to dry?

Drying times for most adhesives vary depending on the type of glue you use. As a general rule, you should wait a full 24 hours for the glue to cure completely. Many cyanoacrylate adhesives are fast-drying, so wait times can range from a few minutes to a few hours. Industrial adhesives will require longer drying times – up to 72 hours.

How do you remove excess adhesive from styrofoam?

Depending on the adhesive you use, you will either use water or acetone. You can remove some water-based adhesives with soap and warm water. Other types of adhesives require stronger solvents, such as acetone. Since acetone can melt styrofoam, you'll need to water it down. With the diluted acetone, you'll remove the adhesive with a cotton swab and let dry.

At what temperature does styrofoam melt?

Styrofoam’s melting point is 464 degrees Fahrenheit or 240 degrees Celsius. This is the temperature that polystyrene, the material that styrofoam is made of, melts.

Does super glue work on styrofoam?

Yes, any cyanoacrylate will work on styrofoam. But on top of bonding the styrofoam, it also melts the material. Anything adhesive with acetone or ethyl acetate ingredients will melt the styrofoam.

Conclusion

Finding an adhesive that works on styrofoam almost seems too good to be true. But with our top pick, or any of our decent alternatives, you’ll have styrofoam sticking to anything in no time. We hope with this guide that you have found the best styrofoam glue for your project.
