From paper mache to creating a sculpture out of styrofoam, the key to success is choosing the right adhesive. With so many products on the market today, it can be hard knowing which ones will really hold their own and which ones are just marketing gimmicks. That’s why I compiled this list of five best glue for styrofoam products available now!
What is Styrofoam?
Styrofoam is a composite of polystyrene and air, which means it’s white or off-white in color. It can be found almost anywhere as insulation for buildings and coolers alike. For example, when you buy food from the grocery store packaged inside an ice chest with styrofoam inserts to keep things cold at night like frozen dinners, those are usually made out of styrofoam.
When I was younger, my dad would create new crafts all the time using nothing but sheets of foam board because they’re so easy to find around your house or office building too! The best part about styrofoam is how inexpensive it is; depending on what size sheet you go with, there may not be a single sheet in the pack that exceeds $100.
This versatility is one of the main reasons why styrofoam has been used for so many different purposes, and there’s always a good use for it. The most common way people are using this material today is to fill up their flower pots with soil or a potting mix! It doesn’t matter whether you’re planting flowers on your porch or balcony because these materials will keep everything nice and fresh either way.

The Best Glue for Styrofoam
The best glue for styrofoam is the one that you’re willing to invest in. I find it best to try a few different types, and see which works best on your project before deciding what type of glue you want to use more often. Remember not all glues are created equal! This list will provide information about five specific brands so hopefully, this can help make the decision easier when choosing between them. So we know how important it is to have something like an adhesive because without any way of securing things together they’re bound to get messy – or worse yet, fall apart completely after only a short amount of time.
Choosing the right product for your home improvement or other repair projects can be difficult. Luckily, we’ve compiled a buyer’s guide to help you make an informed decision on behalf of all those in need! This is everything you’ll ever need before making any purchase, from key terms and specifications that are helpful when comparing products to application information about what these items do best.
Types of Glue for Styrofoam
Depending on the type of styrofoam you’re looking to glue, there are different glues available. For example:
This is an inexpensive form of insulation found in everything from packaging for electronics and appliances to furniture padding. The most common types include extruded polystyrene (EPS) and expanded polystyrene (EPS). When purchasing a glue designed specifically for this material, make sure it says “polyurethane-based” or “latex-based.” These two types will adhere well to EPS without being too rigid. If using standard hot glue with EPS foam, don’t use the non-gap version because it’s hard to remove bubbles between the layers.
Expanded Polystyrene Foam
EPS foam is a common type of styrofoam used for packing, insulation, and furniture padding. It can be found in two different forms: extruded polystyrene (EPS) and expanded polystyrene (EPS). When it comes to adhesive use with this material, make sure the product says “polyurethane-based” or “latex-based.” These types will adhere well to EPS without being too rigid. If using standard hot glue with EPS foam, don’t use the non-gap version because it’s hard to remove bubbles between the layers.
Solid Board Styrofoam
Unlike raw sheets of styrofoam, solid board styrofoam is a flat sheet that can be glued together to produce larger shapes. In most cases, the glue used for this material will need to adhere well on both sides of the foam (i.e., it needs to be waterproof). For example, you could use two-part glues such as epoxy resin or polyurethane adhesive designed specifically for boards and paneling.
This is one of the most common forms of insulation found in packaging, packing materials, and furniture padding. It comes in three different types: extruded polystyrene (EPS), expanded polystyrene (EPS), or solid board styrofoam. When it comes to gluing this material together, you’ll need glue that adheres well on both sides. For example, you could use two-part glues such as epoxy resin or polyurethane adhesive designed specifically for boards and paneling.
This type of insulation is found in packaging materials, packing foam, and furniture padding. It comes in three different types: extruded polystyrene (EPS), expanded polystyrene (EPS), or solid board styrofoam. When it comes to adhesives used on this material, make sure the product says “polyurethane-based” or “latex-based.” These are the only products that will adhere well without being too rigid. If using standard hot glue with EPS foam, don’t use the non-gap version because it’s hard to remove bubbles between the layers.
Styrene-Butadiene Rubber or SBR
This type of foam is used for insulation in packaging materials, packing foams, and furniture padding. It can be found as either extruded polystyrene (EPS) or expanded polystyrene (EPS). When choosing an adhesive designed specifically for this material, make sure it says “polyurethane-based” or “latex-based.” These types will adhere well without being too rigid. If using standard hot glue with EPS foam, don’t use the non-gap version because it’s hard to remove bubbles between the layers.
Another common form of styrofoam is insulation in packaging materials, packing foams, and furniture padding. It can be found as either extruded polystyrene (EPS) or expanded polystyrene (EPS). When choosing an adhesive designed specifically to work with this material, make sure it says “polyurethane-based” or “latex-based.” These types will adhere well without being too rigid. If using standard hot glue with EPS foam, don’t use the non-gap version because it’s hard to remove bubbles between the layers.
This styrofoam form is typically only seen on manufactured homes and residential building construction projects made out of wood framing panels. It’s the perfect insulation material. When choosing an adhesive designed specifically to work with this type of foam, make sure it says “polyurethane-based” or “latex-based.” These types will adhere well without being too rigid. If using standard hot glue with EPS foam, don’t use the non-gap version because it’s hard to remove bubbles between the layers.
This type of adhesive is sold in a liquid form. It’s typically used for attaching items to metal or concrete, but it can also be useful when bonding Styrofoam pieces together. When using this product, make sure the area where you apply the epoxy isn’t exposed to moisture because that could cause it to fail prematurely.
Two-Part Acrylic Adhesives
One of the most widely used types of glue for styrofoam is two-part acrylic adhesives. These are typically made up of a fast-setting epoxy resin, which bonds well to polystyrene foam and has an extended open time that allows you to reposition your components before it sets hard. Epoxies also have good UV resistance, so they will not yellow or crack in the sunlight like some other glues may do over time.
The downside with this type of adhesive is that though all surfaces should be sanded down smooth beforehand if any irregularities exist, these can cause air bubbles or bumps once the adhesive dries because it must fill every nook and cranny. Those imperfections can be sanded down again, but that takes more time and effort.
The other downside is the strong smell associated with some epoxies – not all of them are this way, so it pays to do a little research beforehand if you’re sensitive or have allergies.
Silicone-Based Flexible Glues
Silicone-based flexible glues are another option; they will give you a lot more working time before it starts to set, but there is the potential for the glue to drip or ooze while curing. And once dry, silicone doesn’t bond as well when sanded because of dust particles getting trapped in the surface that can prevent an effective seal from being formed.
If this adhesive does not work out, you should try one with acrylics since these have fewer problems and stronger bonds than some other types available on today’s market. Both qualities are important if you want your styrofoam project to last long term.
Super Glue (Cyanoacrylate)
The third option is super glue or cyanoacrylate. This type of adhesive bonds quickly and does not need mixing to work – just a few drops will do the trick.
Super glue can be bad for some surfaces as it may leave an unwanted residue that doesn’t come off easily in certain cases; this includes painted walls, paper products (like books), metal, aluminum foil tape, and polystyrene foam with acrylic coatings like those found on most packing Styrofoam blocks.
It’s also worth noting that you should avoid contact between two components when bonding them together. If they touch, then there is potential for one side to become tackier than the other, which will cause separation over time no matter what type of glue is used.
The final type of glue for styrofoam is PVA. This adhesive works slowly and does not leave behind any residue when it dries, but because the bond becomes stronger over time, there can be a problem with parts separating at first which means that you’ll need to use clamps or weights on your project while drying instead. As long as these are applied, this will form an effective seal that’s strong enough to stand up to everyday uses like bumping into things accidentally in the workshop.
PVA also tends to have low shrinkage rates, which is another good thing if you’re looking for something more permanent; acrylics may do well here too since they offer other benefits without drawbacks, so take some time to consider the features of each before you make your decision.
How to Glue for Styrofoam – Step by Step
Gluing polystyrene to other surfaces or even other plates of polystyrene is not a complicated process. First, you must select an appropriate glue type suitable for creating a bond on the surface without melting the material. Personally, we think that spray adhesive is a great way to go, as it works well for many applications. Then, you 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!
Step by Step
- Are you looking to stick styrofoam together or onto other materials? The first thing that is needed for this project, of course, is the right adhesive.
- To make the surface dry and clean, use a damp rag to wipe away any particles. Then follow up with a dry towel for an extra step of cleaning!
- Apply the product to your polystyrene surface as indicated in the instructions.
- Clamping the two pieces together will allow it to dry and cure as directed on the packaging.
- The biggest concern with polystyrene is making sure it doesn’t melt in your hands. Polystyrene can become liquid and affect the skin, causing burns or irritation. It also releases carbon monoxide when heated, which could be toxic for humans to have contact with- if you see that foam forming, make a quick escape from it! The pieces of plastic are also hazardous for children as they pose choking hazards due to their size being small enough to get stuck on someone’s throat.
- Additionally, any glue will need to be tested on a small section before going ahead with the entire project to ensure that it doesn’t cause reactions or damage your surface. The same goes for glues like polyvinyl acetate and epoxy resin which can emit toxic fumes! Make sure you’re aware of how this may affect people around you when deciding what product is right for your needs.
- Older styrofoam packaging blocks are also unsafe because they contain asbestos. This material has been shown to increase risks of lung cancer and breathing difficulties, so please don’t use them if you find some lying around from years ago; throw them away instead or donate them since there should still be many uses for them!
- Ensure that everyone is aware of the dangers of handling and using polystyrene before starting a project. You’ll need to be diligent about safety precautions, especially if you’re working with children who are more prone to making mistakes due to their lack of knowledge or ability. Remembering all these things will help keep your home safe for many years while still allowing you and others around you to enjoy projects made out of this material without worry!
FAQ about Glue for Styrofoam
Will hot glue gun melt styrofoam?
Generally no. Hot-melt glue guns apply fragile and hot filaments of molten glue to substrates like paper, card stock, and fabric. The heat melts the synthetic resin that comprises styrofoam but not the foam itself.
This is because tires are made from a completely different substance than paper or cardstock, mainly cellulose (a long-chain polymer containing sugar) as their major constituent. There’s neither cross-linking between polymers nor carbohydrate-binding to water molecules present in this substrate for either the gun glue or solvent vapors to interact with effectively enough to cause any noticeable change on your styro project.
Does super glue work on styrofoam?
Super glue is a polyacrylate, which means that it bonds well with polystyrene. It would work on styrofoam as long as the styrofoam was covered in plastic or something similar. Otherwise, the glue would seep through and bond to whatever is underneath.
What glue works best on styrofoam?
Styrofoam can’t be melted, so you’ll need something to cover it up, such as cardboard. You put the glue onto the cardboard and then use that to cover it up. This means that not any kind of glue will do! Read the instructions for your chosen adhesive, but beware of ammonia-based formulas which release toxic fumes when heated.
How to glue styrofoam to cardboard?
There are many ways to glue styrofoam to cardboard. Styrofoam is simply polystyrene beads covered by a thin layer of foam, so you may consider gluing it down with hot melt adhesive or even a heated gun!
How to glue styrofoam together with adhesives?
- Cut the styrofoam shapes you want to glue together into individual pieces (nicely) and apply a thin layer of liquid adhesive on each piece with a paintbrush or roller.
- Align the two glued pieces face-to-face, then press them together firmly for at least 30 seconds so that most of the surface area has been pressed together. Set the glued pieces aside to dry overnight, preferably upside down, so that any excess adhesive doesn’t drip everywhere during drying time.
- Sand down rough edges with an electric sander once both have set up well enough to stay standing on their own (usually 2 hours later). Sand gently in batches until smooth all over!
What type of glue can you use on styrofoam?
There are plenty of types of glue that are suitable for use on styrofoam and other plastic materials, but you may have difficulty with one type or another. One option is to buy a specialized glue used specifically for foam – they’re often available at craft stores. The other option is to use an all-purpose craft stick, such as Elmer’s School Glues sticks which come in a solid form that can be melted down with boiling water. Once applied, the hot glue will adhere to both polar surfaces of the styrofoam and should remain there until it is deliberately removed by dissolving it again with more boiling water.
What sticks to styrofoam?
Styrofoam is notorious for being a challenging material to erase ballpoint pen markings. For this reason, it has become the preferred surface for anti-demonstration signs in many parts of the world.
Several metals, including aluminum and zinc, can adhere well to styrofoam under certain conditions. The combination of heat and salt will also produce “electrochemical welding” on a plastic surface. This phenomenon was used by NASA Eagleworks researchers from time to time to secure various experimental materials into an otherwise ‘unstable’ configuration without having (for some bizarre reason) access to any permanent adhesive or mounting hardware.
On average, how long do styrofoam adhesives take to dry?
Typically, a 2-part adhesive system (adhesive and catalyst) would take 20 minutes or more to reach full strength. It depends on the temperature outside, humidity in your working environment, how much material you’re trying to glue together, and even the thickness of the pieces you’re gluing (weaker hold). The bond should be strong enough after about an hour.
How do you remove excess adhesive from styrofoam?
You’ll need to scrape away the adhesive you don’t want with a razor blade and then cover what you’ve cut out of Styrofoam with something strong such as duck tape. This will prevent the edges of cut-outs from breaking off and exposing them to moisture. And this will produce a crisp, clean edge on your cuts.
At what temperature does styrofoam melt?
The temperature of styrofoam depends on the type of insulation; however, generally, when exposed to fire, it will melt at around 400 degrees Fahrenheit.
Does super glue work on styrofoam?
Sure! The easiest way to adhere styrofoam to cement or brick is by sandwiching the styrofoam between two pieces of cotton and using super glue on the cotton barrier. You can also use a hot glue gun.
What is the best glue to use on foam board?
There are lots of different adhesives you can use for this. You could go with an instant adhesive that will dry in seconds or a slower drying one like hot glue. Depending on what kind of foam board and project you’re working on, there will be tons of products that will work!
Can I use Gorilla Glue on polystyrene?
Standard adhesives will, of course, work on both types of materials, and they’ll glue them together nicely. But keep in mind that if you’re using standard adhesives to bond the pieces of polystyrene together, it’s going to be a weak joint since there’s no chemical means by which the joints are co-joined like there with a plus/minus electric current from polarized electrodes in case of the Gorilla Glue product.
Does Elmers Glue work on Foam?
Yes. Elmers Glue is made from various synthetic polyesters, the same material used in slipcovers and draperies to withstand pressure against spills. It might work better than most fabric glues on foam because of its cushioned surface quality for absorbing glue more easily than the fabric on flat surfaces like upholstery or table clothes. Another thing you could try would be rubber cement (not latex-based).
How do you glue plywood to styrofoam?
Solder and drill pilot holes for screws in both the wood and styrofoam and then screw (or nail) with long drywall nails into the foam core.
To glue them together, it would depend on what type of glue you want to use. That’s not really a question I can answer about this project. I hope this helps!
Can you use super glue on foam board?
Foam board seems to be more porous than other materials, and any glue that can hold foam will also leave a residue if not properly cleaned off after it is applied. Super glue is not a strong enough adhesive for the task, as you might have guessed from how easily it comes undone when one tries to remove something affixed with it. That doesn’t mean there are no options, though; for safer gluing, use washi tape on one side of the foam board before applying glue, then carefully peel off while the paper backing on the tape makes sure that everything stays together even as you peel back layers of the paper backing.
Will Great stuff melt Styrofoam?
It depends on what you would call great stuff! On the other hand, if it is only slightly cool (i.e., warm) and somewhat viscous or slick, it should just ooze through the Styrofoam unless it was somehow compressed there. Why do we get scolded for using styrofoam cups?
Styrofoam insulates food well, so its usage in America does not contribute to climate change as much as paper with a BLL of about 100%. But most importantly, styrene is a suspected human carcinogen whose emissions are widespread into air and water due to showering off liquid styrene and leaching from cut Styrofoam.
Can I use Mod Podge on Styrofoam?
Mod Podge is a sealant that can be used on all sorts of surfaces, including Styrofoam. Before applying it, the surface should first be coated lightly with vegetable oil or mineral oil to help seal any pores in the material so that water doesn’t seep into its cell structure and cause it to dry out and crumble. Then apply Mod Podge liberally on top of this when the surface is dry to create a barrier between the shape (or object) you’re making and any moisture it may come into contact with. You will need patience because painting on Mod Podge takes time. The dried product should then be polished with some glass paper or sandpaper for a smoother finish.
What is XPS foam?
An XPS foam has some properties as EPS, but it’s easier to cut than polystyrene because XPS foam can be sawed with hand tools like a jigsaw or handsaw. In contrast, polystyrene needs special equipment called an electric trim router which costs hundreds of dollars. In addition, XPS foam tends not to warp when exposed to moisture over time, so you may get better durability if your XPS products have regular exposure to water or other corrosive materials such as salt air from coastal regions where
It comes in both solid forms (think packing peanuts) or an expanded version, which can be shaped into many different things like snowmen! XPS foam is another name given to the styrene-butadiene-styrene variety of polystyrene sheets. XPS has become popular because it doesn’t contain any harmful chemicals such as benzene or asbestos-like other types of plastics do – though you should always wear gloves when handling XPS sheets because they’re still a material made from petroleum-based materials that are known carcinogens
