Best Glue for Styrofoam: Top Picks & Pro Tips

best glue for styrofoam

If you’ve ever worked with styrofoam, you know how challenging it can be to find the right adhesive for the job. Using the wrong glue can result in weak bonds and project failures. That’s why it’s crucial to choose the best glue for styrofoam to ensure a successful outcome.

In this article, we will take a deep dive into the world of styrofoam adhesives, providing you with the information and resources you need to make an informed decision. We will explore the unique properties of styrofoam and the specific characteristics to consider when selecting the right adhesive. We will also share our top picks for the best glue for styrofoam and provide you with a step-by-step guide on how to use it effectively.

Understanding Styrofoam and Its Bonding Properties

Styrofoam, also known as polystyrene foam, is a common material used in various projects, from packaging to crafting. However, finding the right adhesive to bond styrofoam can be tricky due to its unique properties.

Styrofoam is lightweight, porous, and has a low surface energy, making it resistant to adhesion. Therefore, selecting the right adhesive is crucial to ensure a strong and durable bond. Using the wrong glue can result in a weak bond, causing the styrofoam project to fall apart.

Styrofoam bonding requires adhesives that can penetrate the porous surface and create a strong molecular bond. The ideal adhesive for polystyrene foam should also have flexibility to withstand any bending or twisting without cracking the bond.

When selecting an adhesive for styrofoam, consider the specific characteristics of the bond you want to achieve. For example, if you are bonding large surfaces, a fast-drying adhesive may be more suitable to prevent the glue from drying out before application.

It’s also important to consider the environment the styrofoam project will be in. For example, if the project is going to be exposed to high temperatures, using an adhesive that withstands heat is crucial to prevent the bond from weakening.

How to Use Glue for Styrofoam: A Step-by-Step Guide

Using the right glue for styrofoam is critical to ensure a strong and reliable bond. Follow these simple steps to use styrofoam glue effectively:

  1. Prepare the surface: Ensure that the surfaces you need to bond are clean and dry. Dirt, grease, or moisture can affect the bond strength. Use a damp cloth to wipe the surfaces and let them air dry before proceeding
  2. Apply the glue: Apply the glue to one of the surfaces you need to bond by using a small amount of glue. You can use a brush, spatula, or a syringe to apply the adhesive
  3. Spread the glue: Spread the glue evenly over the surface using a brush or spatula
  4. Join the surfaces: Press the two surfaces together tightly and hold them in place for a few minutes to allow the glue to dry. Abstain from moving or adjusting the surfaces while the glue is setting
  5. Let it dry: Leave the bonded surfaces to dry for at least 24 hours before using or handling them. The glue will continue to set and cure over this time, resulting in a stronger bond

Remember, different types of styrofoam glue have different drying times and bonding strengths. Follow the instructions on the product label for best results. Avoid using the glue in extremely hot or cold environments, as it can affect the curing process and the bond quality. For more complex projects, it’s best to test the glue on a small surface first to ensure that it’s effective and won’t damage the material.

Each of these glues has its unique features and strengths. Aleene’s Original Tacky Glue is a popular choice for its ease of use and affordability, while Gorilla Super Glue offers exceptional impact resistance. Loctite PL300 Foamboard Adhesive is ideal for large surface areas and other foam materials, while 3M Super 77 Multipurpose Adhesive is versatile and fast-drying.

It’s important to note that while these glues are all suitable for styrofoam, they may have limitations depending on the specifics of your project. Always follow the manufacturer’s instructions for optimal results. And remember: Styrofoam is a delicate material that can deform or break easily if not handled gently. Avoid putting too much pressure on the glued parts and use support props if needed.

Alternative Adhesives for Styrofoam

While specialized styrofoam glue is recommended for optimal bonding, there are other adhesive options available for specific scenarios. Here are some alternative adhesives to consider:

Adhesive Type Pros Cons
Epoxy Strong bond, suitable for heavy loads Requires mixing, longer drying time
Cyanoacrylate (super glue) Fast-drying, easy to apply May not bond well with all styrofoam types, can be brittle
Hot glue Quick and easy to use, versatile May not bond as strongly as specialized styrofoam glue, can be messy
Double-sided tape Clean and easy to use, good for lightweight projects Not suitable for heavy loads or outdoor use, may not bond with all styrofoam types

It’s important to note that alternative adhesives may not provide the same level of bonding strength and durability as specialized styrofoam glue. Always test the adhesive on a small area before using it on a larger project and monitor its performance over time.


In conclusion, choosing the right glue for styrofoam is crucial for achieving strong and durable bonds in your projects. We have provided an overview of the top picks in the market, which offer quality, effectiveness, and ease of use. Remember to consider the unique bonding properties of styrofoam and the specific characteristics of the adhesive when making your selection.
