Best Glue for Foam in 2022: Product Recommendations & Usage Guide

Foam is one of the easiest materials to work with because it is lightweight. Unlike heavier materials, foam usually doesn’t need a long clamping time, and most glues will work very well.

However, that doesn’t mean every glue will do the job equally well.

Depending on the texture of the foam and other materials you’re using, as well as the surface and weight of your materials, you’ll have to choose a glue that’s both compatible and strong enough.

But don’t worry! In this article, I’ll put together a list of great foam glue options for any situation.

Recommendation: 3M Super 77 Multipurpose Permanent Spray Adhesive takes the first spot due to its high versatility and performance. This industrial-grade, sprayable glue is perfect for a wide array of lightweight materials, including foam. It doesn’t soak into materials, it bonds fast and with an incredible hold, and dries completely clear.

Best Glue for Foam in 2022

Suitable Glues for Foam

There are lots of glues on the market for every material imaginable. If you’re considering buying foam adhesive, you’ll be happy to learn that almost any type of adhesive works on this material.

Foam is versatile. You can use contact adhesives, Styrofoam glue, carpenters glue, wood glue, two-part epoxies, and many more.

To narrow down your options, you might want to consider the following types of glue. These should work well to bond foam to most materials.

Super Glue

Super glue is a great option for small fixes or DYI projects, and it works well even for heavier-weight materials.

However, this foam adhesive is strong and can melt through foam or plastic. You might want to avoid using super glue for surface repairs.

Another downside is that this type of foam adhesive is heat-sensitive. Many super types of glue are also not waterproof.

Hot Glue

Hot glue is a great option for DYI art and any craft project. It dries fast and clear, although it doesn’t hold the strongest. Therefore, it’s best used for low-weight materials.

Despite its name, hot glue works great for bonding foam to foam and other materials, perhaps except for thin, heat-sensitive plastics.

It’s usually not hot enough to melt through the foam, so you can also use it for surface applications.

Polyurethane Adhesive

Polyurethane adhesive is highly versatile and suitable for all materials, including foam, foam board, plastic, wood, rubber, stone, leather, and metal.

It works equally well on porous and non-porous surfaces.

Depending on the formulation, this adhesive can dry with either a flexible or rigid hold without compromising the strength of the bond.

Remember that polyurethane uses heat to cure, although you don’t need any special lamp to do the job. Even room temperature is enough to kickstart the curing process.

Best 8 Glues for Foam & Foam Board

1. 3M Super 77 Multipurpose Permanent Spray Adhesive


  • Dries very fast and clear
  • Works with acoustic foam & open cell foam & closed cell foam

This glue’s powerful hold allows you to use smaller quantities of the product without compromising on great results.

This adhesive also dries clear and rigid without becoming brittle.

The Loctite Clear Silicone Waterproof Sealant has a quick-acting, powerful, and permanent hold, so there’s little room for error.

Once the adhesive sticks, you can no longer move the materials around.

Another potential problem is that this glue might soak into the foam if applied in large quantities.

Loctite Clear Silicone Waterproof Sealant is perfect if you need glue for patching gas tanks.

4. Permatex 80050 Clear RTV Silicone Adhesive


  • Comes with control tip
  • Works with polystyrene foam

This adhesive has a gentle formula and thin yet non-runny consistency.

You can apply it in a thin layer and dries clit ear with a durable hold. This glue is also water and vibration-resistant.

It has a weak smell and also remains somewhat tacky when dry.

6. Aleene’s Felt and Foam Tacky Glue


  • Comes in a large bottle
  • Very high bond strength
  • Dries very fast


  • Not that easy to use

Aleene’s Felt and Foam Tacky Glue is another silicone-based glue with a strong hold and a short drying time.

This adhesive is specially formulated for felt and foam, and it works great on many other surfaces, both porous and non-porous.

Thanks to its formula, this glue is easy to control as it doesn’t drip or slide.

This adhesive also dries clear, so you won’t have to worry about any inaesthetic white glue stains.

This glue could be tacky when dry, depending on the quantity applied and material adherence.

This could become a problem if you use the glue for visible details, so it’s best to save this one for the hidden surfaces.

Thanks to its consistency and grey color when wet, this glue is incredibly easy to apply and control.

When dry, the glue turns completely clear and bonds the surface tightly.

Remember that this adhesive has a medium viscosity, which means it could easily drip or run and absorbs and expands into soft or porous surfaces.

This glue also requires a rather long clamping time of up to 2 hours for optimal results.

Gorilla Original Waterproof Polyurethane Glue is a great option if you are looking for glue for balsa wood.

8. FloraCraft Non-Toxic Foam Glue


  • Very easy to apply
  • Bottle does not clog

This glue has a high viscosity and comes with a non-clog tip, making it easy to apply and control.

The product comes out white and dries clear, forming an adhesive bond. This glue isn’t as strong or flexible as the other options on the list,

being better suited for lightweight materials and small arts and crafts projects.

Tips for Using Foam Glue

Foam is one of the easiest materials to work with, given its lightweight and versatility.

As with any other material, half the job involves choosing the right adhesive for your project.

However, once you get that part down, there are some extra things to consider for optimal results.

Always ensure that the foam material you’re using is clean. Even a thin layer of dirt or dust can interfere with your glue’s work by lowering its adhesive power.

If you must use a damp cloth to clean the material, always wait until the surface is completely dry before applying any glue.

You should apply glue to just one of the surfaces you’re trying to glue together. If you’re using a strong-bond adhesive, just a thin layer of the product should be enough.

Make sure they thoroughly read the instructions on the glue you’re using. Clamping time might differ depending on brand and product.

Wrap Up

Foam is a multi-purpose material used in household renovations, clothing and costuming arts and crafts projects, and many more domains.

Luckily, it’s also compatible with multiple types of glue, so you have many options to choose from.

Whether you need instant-bonding, slow-drying, flexible, or tacky glue, we’ve included plenty of options for all your foam glue needs.

Always check the instructions on the label to ensure that the glue you’re buying works for the specific type of foam you’re using.
