Best Glue for Styrofoam

Table of Contents

At Cleaning King, glueing styrofoam shouldn’t be a hassle.  From so many glues to choose from, we at Cleaning king have curated a list of the best glues for styrofoam.

Polystyrene, known as Styrofoam and polyfoam, is essentially plastic filled with about 90% air, making it moisture resistant and super light. It is a good insulator for walls, boxes filled with produce, arts and crafts and industrial related projects.

Due to its unique qualities, not all glues will work well with Styrofoam.

As a widely used thermoplastic, choosing Styrofoam for your projects makes it easy as it is lightweight, resistant to acids, and cheap. However, Styrofoam is a fragile material that can break quickly and dissolve with the wrong glues as it is not resistant to solvents and gasoline.

Polystyrene comes in various densities, so it will be worthwhile to see which type of glue you will need for either styrofoam or XPS foam. Styrofoam and XPS foam are a versatile material, meaning it can be glued to absorbent and non-absorbent surfaces such as wood, metal, paper, concrete, drywall, plastic and many types of soft materials like felt.

Suppose you are using styrofoam for arts and crafts. It’s essential to find glues that will have properties to protect the piece’s final aesthetic. Generic glues that are not specialised for styrofoams may melt, dissolve or yellow over time the styrofoam surface.

Furthermore, suppose you are using XPS foam for industrial related projects. In that case, you will need to seek glue that is specially made for insulation foam boards.

Polystyrene is easily flammable and may release pollutants such as carbon monoxide into the air, so choosing a glue that is not hot or easily flammable will be crucial when choosing the best glue for styrofoam.

Here are our tips for best glues on the marker for polystyrene, styrofoam and XPS foam.

Buyers’ Guide- Best glue for Styrofoam

The Cleaning king team has compiled the best features to look for when looking for the best glue styrofoam, XPS foam and polystyrene. Glues will either come as a liquid glue or a spray-on adhesive. These are features you should look for when it comes time to purchase glue.

Versatility

The best glue for styrofoam will work at glueing styrofoam to various surfaces such as; paper, wood, metal, fabric leather, felt, cork, glass, plastic, and other surfaces.  However, this will entirely depend on what you intend to glue styrofoam on. A generic glue will work well for arts and craft project and other lightweight surfaces.

Yet an industrial graded glue will be best for heavy-duty projects that would require lots of durability and permanence when bonding to brick, concrete and drywall.

Adhesives for any project will depend on the formula, whether it’s a specialised formula for XPS insulation foam or a generic glue for household projects. 

Toughness

The best glue for styrofoam will be durable and permanent. It should be firm and resistant to wear and tear. If you’re working on a serious project, it’s best to look for maximum toughness that won’t break the bond from moving around too much. Industrial glues for polystyrene will typically have a curing time, which will take longer than standard adhesives to set but will dry with more durability in this time frame, so it will be worth the time waiting.

Fast drying

If time isn’t on your side, a fast-drying glue for styrofoam will be your best bet for arts and crafts or industrial projects. A Lot of the glues mentioned are great in drying and bonding two surfaces together quickly. Most adhesives on the market can glue within a 1 minute or up to 10 minutes if you apply smaller coats. This will also mean you won’t be exposed to potentially harmful fumes or VOCs if you reduce your exposure time while handling a styrofoam glue.

Low VOCs

Excellent glues for styrofoam but more importantly for yourself will be non-toxic. That means it should have low VOCs so that it won’t emit intense fumes that won’t irritate your nose, skin, or eyes.

Essentially an odourless glue will be best, as well as a fast-acting glue, which will reduce your time exposed to any potentially harmful fumes.

Even if you don’t have respiratory-related symptoms that may be irritated with such adhesives, some people with no past illnesses have experienced respiratory symptoms when exposed to these fumes, so don’t count yourself out, adequately ventilate your work area if you are working with these types of glues.

Waterproof

The best glue for Styrofoam will be waterproof when it sets. Meaning any future spills or wet weather won’t deter your project. Many types of glue will be easy to clean-up with water. However, this is only in the glueing process and won’t be susceptible to water after it sets and cures. Most glues will also easily clean-up with water after you are done with your project.

Temperature resistant

Excellent glues for styrofoam will be resistant to temperature changes, including intense hot weather and freezing weather. It shouldn’t wear your styrofoam. Our best glue for industrial usage is excellent for indoors and outdoor settings and resistant to temperature changes.

A temperature resistant glue for styrofoam is most likely only a problem for glueing insulation foam boards or XPS foam rather than for art and craft related DIYs.

Non-yellowing

Excellent glue for styrofoam will have a non-yellowing formula. Meaning it won’t turn yellow over time or discolour your styrofoam and other surfaces. This is especially important for art projects if aesthetics are important. Not all glues will mention a non-yellowing feature, so look for this feature, and you will be in good hands.

Type of styrofoam

You should check which foam you are working with such as;  styrofoam, polystyrene and XPS foam. Some foams are for insulation such as XPS foam. Not all glues will work with each type of foams. Some adhesives emphasise that they work with various foams, so these may be a better option if you are not sure which foam you have.  Always ask for guidance at your local store if you are still unsure.

Solvent-free

Your styrofoam glue should be free of solvents. Solvents will melt and dissolve your styrofoam surface. Such solvents include; acetone and gasoline. A non-solvent based glue for styrofoam will be your best bet. Solvents will also typically contain toxic fumes, and also be bad for your health.

Avoid hot glue

When glueing styrofoam with other surfaces, do not use hot glue such as a hot glue gun. Hot glue will also melt your styrofoam surface if directly applied mainly if both surfaces are styrofoam however if you’re glueing styrofoam to another non-styrofoam surface, its best to use the glue on the non-styrofoam surface and wait for it to become tacky then bonding it with the styrofoam surface.

Instant grab

A Lot of styrofoam glues have an instant grab feature. Meaning you won’t need other pieces to hold the styrofoam and other surfaces together. Fitting the pieces together with maximum durability.

How to glue styrofoam

Not sure how to glue styrofoam to your surface? Our Cleaning king team have carefully laid a general plan below, to guide you in glueing styrofoam to your desired consistency. These steps will depend entirely on the other non-styrofoam surface you are using and the glue you are using. You should check each glue’s specific instructions for optimal results.

Tools needed:

  • Styrofoam, Polystyrene or XPS foam
  • Other desired surface
  • Foam Glue
  • Glue brush
  • Dry rags
  • Warm water
  • Sandpaper (optional)

 

  1. Clean your workspace from debris and liquids. Water may interfere with the glue, and some may not be waterproof.
  2. Clean your styrofoam surface. The styrofoam surface should be free of dirt and liquids, as these types of debris may interfere with the glue formula and not make it work as it should.
  3. Depending on the surface you wish to glue styrofoam on, such as wood. It’s a good idea to sand the body to make it smooth. An uneven surface may not glue well to styrofoam.
  4. Carefully plan where you wish to glue your styrofoam. Most glues will instantly dry, so it’s a good idea to prepare precisely where you will glue as it will become a hassle if you change your mind. Most glues are also super durable. Some adhesives allow repositioning for 10 minutes with a thin coat. If you know, you won’t be sure where the final bond will be.
  5. Apply even coats of the glue with a brush to both surfaces you intend to bond together. Stick the parts together then let it sit in a safe spot, and wait for it to dry before grabbing it again.

Conclusion – Best Glue for Styrofoam

Incorrectly choosing the wrong type of glue for styrofoam, polystyrene, or XPS foam can quickly melt and destroy the surface. Especially with solvent-based adhesives and hot glues.

Your DIY and industrial projects are important to you, so choosing the right glue will be crucial for longevity and durability.

If aesthetics is necessary, a glue that dries clearly will be great in not changing your final project’s image. A non-yellowing bond will also be required, so it doesn’t yellow over time and ruins your styrofoam creation. It may become difficult to paint over the glue or even remove it.

Most adhesives will be permanent. If you are not sure where the final styrofoam or XPS foam will be placed, a bond that allows repositioning will be essential to trial where it will end up.

Another thing to note is for yourself. Some general glues may contain solvents like acetone or toluene. These solvents will dissolve and melt your styrofoam and XPS foam. Therefore it’s essential to buy a specialised glue for styrofoam or XPS foam.

By now, you should have a better understanding of the types of glues or adhesives for polystyrene, styrofoam and XPS foam. There’s a glue for small and large scale projects.

Cleaning King's Choice - Best Glue for Styrofoam

Best Glue for Styrofoam FAQs

 

Superglue, also known as Cyanoacrylate, can glue styrofoam to other surfaces. It should be used with care, as it can cause the styrofoam to melt slightly.

 

Polystyrene is a solid plastic that can be made into various consumer products. Polystyrene can then extruded to create a foam material like expanded polystyrene (EPS) or extruded polystyrene (XPS)

XPS foam stands for Extruded polystyrene insulation. XPS foam is widely used for insulation which is sometimes also known as XPS insulation. XPS foam is made differently from standard styrofoam in that it undergoes through an extrusion process. You will need to buy specially formulated XPS foam adhesives.

 

Styrofoam is known as expanded polystyrene foam or eps foam. Styrofoam is used for arts and crafts related projects and thermal insulation. Depending on the strength of eps foam, it is excellent for not absorbing water and vapour. It’s essential to note styrofoam is made from polystyrene.

 

VOCs also known as Volatile Organic Compounds, are chemicals that tend to evaporate at room temperature. VOCs tend to be found in some glues for styrofoam, XPS foam and polystyrene. These chemicals tend to emit harmful fumes that may irritate your respiratory system. So it’s a good idea to ventilate your working area to properly circulation. Breathing these fumes may become toxic to people with respiratory-related illnesses and even those without.

 

A solvent is a chemical that is a substance where a solute is dissolved. Styrofoam and other polystyrenes can be dissolved in an acetone solvent. So it’s best to stay away from glues containing solvents.

 

Hot glue guns should be avoided as the hot temperature will melt the foam surface. If there is no other option, you should glue the other non-styrofoam surface and then glue that to the styrofoam. Ideally do not apply hot glue directly to styrofoam. Using hot glue with styrofoam is likely to emit toxic fumes, so its best to not use the highest temperature.

 

Curing time for styrofoam or XPS foams means the time for adhesives to reach full strength. Curing time is a typical term for industrial-grade glues. They are often stronger and more durable than ordinary styrofoam adhesives. The more durable it will be the more time it will take to reach its full bonding potential. Curing time can take days to weeks to a month for larger-scale projects

 

To remove glue or adhesive from styrofoam, you can use warm water or acetone with soap. This will work on water-based glues. However, you should dilute any sort of solvents with water to prevent any melting of the styrofoam. You should be wary that some bonds are permanent and may be difficult to remove. You will need stronger solvents for tougher adhesive removal with pressure.

Most glues on styrofoam will instantly set or take about 10 minutes for adhesives that allow repositioning. The more glue you coat on styrofoam, the less time you have for repositioning the surfaces. It may take longer for industrial projects, typically with a curing time added to allow the glue to set for maximum durability.

 

 

A polystyrene type of glue or spray adhesive is best for styrofoam, or XPS foam. Other glues won’t work well and may melt the surface.
