Styrofoam is a soft, light material that is most familiar with its use as insulation and product packaging. You can use Styrofoam, for either on some kinds of school projects or your crafts. However, knowing how to properly glue a Styrofoam to a variety of surfaces you can make strong and sturdy projects.

What Kind of Glue can be Used in Styrofoam?

One can use a variety of glue to attach Styrofoam. Some of them are mentioned under,

  • You can use basic craft glue for simple needs like casual arts and craft projects. You can also apply Styrofoam glue that particularly attaches Styrofoam.
  • Then there is spray adhesive which you can also use. Lastly, you can use a low-temperature hot glue gun to attach Styrofoam.

How do You Attach Two Pieces of Styrofoam?

You can use PVA (standard white glue) for a thin bond line when it comes to attaching two Styrofoam. Cyanoacrylate or commonly known as the superglue works very well in attaching two Styrofoam. You can consider the following points when you try to attach two Styrofoam,

  • The glue slightly melts the Styrofoam besides bonding it together.
  • However, you can use some polyurethane glue as well. Use a PL Premium (caulk) for the best results. You will get good outcomes using spray foam to stick two Styrofoam sheets.
  • Moreover, you can use a latex caulk, but can’t apply it between large sheets, as it needs to dry out. There are good reviews about the contact adhesives, yet you must apply water-based to ensure that the solvent won’t dissolve the Styrofoam.
  • You can also use low-temperature hot glue.

Can You Use Super Glue on Styrofoam?

In simple words, the answer is NO. This is because; super glue contains some organic solvents like acetone, ethyl acetate, etc. The manufacturers usually make Styrofoam from thousands of molecules of styrene by linking it together. Styrene in itself tends to dissolve in all these organic solvents. However, a lot of these molecules are linked together. Hence, it cannot dissolve as it is very big. So, you get the melting effect, instead of dissolving.

What is the Best Glue to Use on Foam?

You can consider the Silicone glue the best to use on Styrofoam to date. This is because silicone and synthetic foam bonds well. As the glue dries, the silicone glue is bonding and sealing adhesive which allows you to influence foam rubber.

  • The Silicone glue suits well with silicone rubber. It is comparatively easy to purchase a Silicone Glue at any hardware or a home improvement store nearby.
  • From making big construction projects to making costumes that need to be mobile, the silicone glue is tough. Moreover, it bonds permanently with the appropriate type of foam rubber.

How to Glue Styrofoam to Glass?

When you are gluing glass with Styrofoam, you must reflect on the visibility of the adhesive you are using. You will need glue that dries as clear as possible if the glass is transparent. Styrofoam is a plastic substance that has been fluffed up like a milkshake and then alleviated that way. That is why it is so much light in weight. The most vital things to consider while gluing a glass with Styrofoam are,

  • You should never use any adhesive which contains a solvent. The solvent will erode the Styrofoam discharging all sorts of toxic fumes.
  • You need to select adhesives that are suited for non-porous materials since Styrofoam is non-porous plastics.
  • Never apply hot glue directly on Styrofoam. There are a few cases when hot glue is a suitable adhesive. However, it should be used on the material you are bonding the Styrofoam too. Also, you need to leave it to cool down for a few seconds before contacting the Styrofoam. This glue will disappear in the hole which it has already burned, and burning plastics discharge toxic fumes.
  • You shall always remember that this glue is only as sturdy as the weakest substance in the union. You can easily break Styrofoam since it has a very low tensile strength. While testing, if you notice that the Styrofoam broke before the bond, then the glue can be considered strong enough.
  • Most importantly, you need to ensure before gluing any glass bond that the glass is clean enough. Make sure that it is dry and free of any oil.

Gorilla Glue Styrofoam

Gorilla glue falls in the same category as the silicone caulk. It has some very limited use for which the gorilla glue works well. However, unfortunately, it has been hyped through the sales pitches to a point where people fallaciously believe that they’re the one-size-fits-all for all the applications. But, that is undoubtedly not the scenario. So, Gorilla glue is not good glue for attaching Styrofoam.

  • The gorilla glue is suitable for a brittle state whereas the Styrofoam is a highly flexible material.
  • This results in the joints to fail quickly. You can see many things getting destroyed by Gorilla glue than anything else.
  • You will face problems in repairing it in later times. Hence, Gorilla glue most often turns simple and cheap repairs into very expensive replacements.

Glue Styrofoam to Metal

You can witness a metal to get heated or even to cool down rapidly without protective insulation. Hence, when you expose a metal substance to the sun, it becomes tremendously hot. Similarly, it gets extremely cold when exposed outside in a colder climate. Attaching Styrofoam to one side of the metal will reduce the amount of heat transfer through the metal. The points to consider while attaching Styrofoam to metal are,

  • Apply adhesive using long and uniform strokes until you obtain a medium coat of glue on the metal surface.
  • Avoid applying a thicker coat. A thicker coat will chunk out any traces of the metal below the glue.
  • You have to allow the glue to dry for ten minutes or until it becomes tacky when you touch.
  • Line up the cut piece of Styrofoam along with the glued metal. Then, press the Styrofoam firmly to the metal surface.
  • Move your hands all along the surface of the Styrofoam until it sits solidly against the metal surface. Finally, it creates a permanent bond between the two materials.

How to Glue Fabric to Styrofoam?

The Crafters can build amazing projects attaching fabric to Styrofoam. This combination works remarkably well for wreaths and ornaments. You must remember while deciding how to attach the fabric to Styrofoam that Styrofoam is a plastic base and all plastics are non-porous. Hence, if you apply an adhesive to fix the fabric, ensure that it is appropriate for use with all the non-porous materials. Things you will require for attaching fabric to Styrofoam are,

  • Pushpins
  • Knitting needle
  • Hot glue gun
  • Hot glue sticks

Glue Paper to Styrofoam

Styrofoam can be a great surface on which you can choose to mount paper documents, mainly if you’re using glue. Hence, if you’ve been thinking of glue Styrofoam to paper, simply follow these helpful tips,

  • Use the appropriate amount of glue. If you use too much glue, then your adhesive will show through.
  • After applying an adequate amount of glue to the back ends of the paper, spread them across Styrofoam boards in a preferred manner.
  • Then use a big piece of glass to tightly press down over the two. You have to make sure to give 24 hours of drying time.


  • Never use too much glue while attaching fabric with Styrofoam.
  • Always clamp with something after gluing a paper with Styrofoam.
  • Don’t use excessive adhesives to Styrofoam. It affects in the long run.

What kind of glue is used for Styrofoam?
