How do you glue insulation foam?
Mod Podge is like a slightly less intense version of contact cement, and it plays pretty nicely with insulation foam. Mod Podge can also be used to seal insulation foam before painting, though it doesn’t add much strength or reinforcement to the foam. Wood glue: Another option is wood glue.

Best Adhesives for Insulation Foam
Attach & Build Double-Sided Films: Attach & Build is a double-sided peel and stick adhesive film that works with almost any cosplay material, including insulating foam. Attach & Build is non-toxic and will not cause an adverse reaction with the foam. You can cut the panels to any size or shape, then simply peel and stick to create an instant bond between pieces of foam or foam and other materials. Attach & Build is a great solution when working with one or more tricky materials. Spray Adhesive: Spray adhesives (such as those made by 3M or Elmer’s) are ideal for building with foam insulation. First, spray adhesive doesn’t react negatively with your foam, so that’s a plus. At the same time, spray glue lets you cover large areas in glue fairly quickly, so it can be particularly useful for those large, light weapon/prop builds and for sandwiching foam to form thicker layers. Another benefit of spray adhesive is that it doesn’t add much weight or thickness to your foam as the formula is quite flimsy but also quite strong. Side note: you should be careful when spraying or covering your work area with something disposable like newspaper, as any overspray will basically leave your supplies or table permanently sticky.
{{cta(‘3698bbd9-607d-4365-b560-16b472ca9c34’)}} Mod Podge: If you want to stack layers of insulating foam to get a thicker panel, Mod Podge is also a good adhesive option for you. Mod Podge is like a slightly less intense version of contact cement and plays pretty well with insulating foam. Mod Podge can also be used to seal insulation foam before painting, although it doesn’t add much strength or reinforcement to the foam. Wood glue: Another option is wood glue. Since wood glue also does not react with insulation foam, it can be used both for gluing parts together and for sealing before painting. Since wood glue usually comes in a bottle, it can be very handy for gluing smaller foam pieces together or filling small gaps between your foam pieces. Hot Glue: Finally, hot glue is another adhesive option for insulation foam, but this option comes with strings. Hot glue works with insulation foam, but it can also melt the foam a bit. Because this is solely due to the heat of the glue and not a chemical reaction, it only takes a few seconds to melt before the glue cools. Because of this, you can use hot glue in places that aren’t visible, such as: B. Grip pockets you brought out for props and weapons.
Insulating foam and adhesive reactions
While the adhesives listed above (and possibly others) can be incredibly effective for various insulating foam constructions, several other adhesives can cause negative reactions that can destroy your insulating foam and ruin your cosplay. While contact cement is an ideal bonding option for EVA, L200, and craft foams, it eats up insulation foam almost immediately. Most super glue (or CA glue) will also cause insulating foam to break down and disappear, creating holes or indentations in your cosplay or prop. Too much hot glue in conspicuous areas can also cause nicks and weak points in your insulation foam, so we recommend only using hot glue in very hidden areas when necessary. As long as you pay attention to those adhesives that cause reactions, you should have no problem building amazing props and cosplays with insulating foam.
Can I use Loctite spray adhesive on Styrofoam?
Its superior bonding strength works effectively on bonding most household materials, including wood, metal, acrylic, foam, fabric, glass, and most plastics.
The Best Glues for Styrofoam of 2022
Spray adhesives are ideal for a variety of uses. They are commonly used for craft and art projects, repairing furniture and appliances, and mending leather or fabric, among other things.
Some spray adhesives are repositionable, allowing for detailed placement. Check the manufacturer’s instructions to find out if yours is one of them. Most sprays dry clear and will not bleed through or wrinkle, resulting in an invisible bond that preserves the original look. Ease of application allows for trouble-free multiple coats and ensures strong bonds without additional drying times.
Spray adhesives can be used to bond wood, metal, acrylic, foam, fabric, cardboard, leather, corkboard, glass, foil, rubber and many plastics. Some spray adhesives are not recommended for high temperatures or humidity, so consult directions before use.
How do you glue polystyrene to polystyrene?
Cyanoacrylates – All Permabond cyanoacrylates bond well to polystyrene. Use only enough adhesive to cover the joint, then assemble as soon as practical. For best appearance use a low odor grade such as Permabond 940. Two component epoxies bond well to polystyrene.
The Best Glues for Styrofoam of 2022
Properties of polystyrene:
Surface energy: 41mJ/m²
Maximum operating temperature: 65 °C
Softening point: 107°C
How do you glue styrofoam?
Polystyrene can usually be glued in the delivered condition without cleaning. If cleaning is required, clean with isopropanol or other mild detergent. Solvents such as acetone can attack the polystyrene.
When designing the joint to be bonded, consider incorporating a stop or control into the joint to avoid over-inserting one part into another, which can cause hoop stresses and stress cracking over time.
Regarding the process – avoid long adhesive dwell times before curing and avoid excess adhesive on the part to minimize the risk of stress cracking.
Adhesives that stick well to polystyrene include:
Cyanoacrylates – All Permabond cyanoacrylates adhere well to polystyrene. Use only enough glue to cover the joint, then assemble as soon as possible. For best appearance use a low odor quality such as Permabond 940.
Two-part epoxies adhere well to polystyrene. Permabond ET500 is a clear, non-yellowing, fast setting epoxy resin.
UV Curable – UV curable adhesives are an excellent choice for bonding polystyrene. Permabond UV630 and Permabond UV640 add resilience to the joint as the elongation of both adhesives is over 110%. Permabond UV630 is low viscosity and UV 640 is medium viscosity.
Can I use super glue on polystyrene?
Super glue and plastic
Working with plastic? Super glue’s strength and speedy application makes it a great choice. A super glue designed for plastic is perfect for repairing Plexiglass, polycarbonate, polystyrene, and polyvinyl chloride (PVC).
The Best Glues for Styrofoam of 2022
Superglue usually comes in liquid or gel form. Liquids are best for penetrating cracks or fractures and generally dry faster than gels. Gels create a more flexible bond than liquids and their higher viscosity means less dripping and offers a more controlled application for projects that require greater precision or vertical application, like building models or fixing delicate cutlery. Loctite offers a range of liquid and gel instant adhesives that are tailor-made for each job.
How do you attach Styrofoam together?
For simple, casual arts and crafts projects, the easiest way to glue Styrofoam is usually to use an ordinary white glue. This basic glue works reasonably well for a wide variety of uses, especially for gluing Styrofoam to construction paper, cardboard, and wood.

To glue Styrofoam, first choose a glue that best suits your needs. Use plain craft glue for simple arts and crafts projects, or try hot glue or spray glue if you need to attach Styrofoam to metal, plastic, paper, cardboard, or wood surfaces. Next, wipe down both the Styrofoam and the project surface with a clean, dry rag to remove any dust that may affect adhesion. Apply the glue to the styrofoam surface in a thin, even layer, then gently press the styrofoam piece onto the other surface. Be sure to let the glue dry completely. If you want to learn what types of glue not to use on Styrofoam, keep reading the article!
Will epoxy stick to polystyrene?
With Polystyrene or Styrofoam, you can’t directly apply Polyester or Epoxy directly to Styrofoam, as it will melt the foam.
The Best Glues for Styrofoam of 2022
Your first step must be to find out what type of foam it is. Certain types of foam have different temperature fluctuations. Polyurethane foam, like the types we sell in 4′ x 8′ sheets, offers different temperature variations than things like polystyrene. Once you figure out what foam you have, you can figure out what to do.
With polyurethane foam, it easily withstands polyester or epoxy applied to it without doing anything special. We recommend sanding the surface with some sandpaper to get the best adhesion, but once the standard surface preparation is complete you can apply your gelcoat, resin or epoxy.
With polystyrene or styrofoam, you cannot apply polyester or epoxy directly to styrofoam as this will melt the foam. Luckily, we have a few products that you can use to make it work anyway. The first product is an FGCI product called Styrocoat, which uses a standard epoxy activator and forms a protective shell over the styrofoam. The other product is made by Duratec and is called the Styro-Shield. Styro-Shield is a polyester based product that uses MEK-P and once cured provides a protective layer.
No matter what type of foam you use, we have a way to make your fiberglass mold or fiberglass-based product. Don’t forget that if you have any questions, we’re here for you! Call us at 1-800-272-7890, email us, or reach out to us on Facebook or Twitter!
What glue will stick foam to metal?
For the strongest bond we recommend: LePage’s Metal Epoxy. J-B Weld.
The Best Glues for Styrofoam of 2022
Styrofoam on metal
For the strongest bond we recommend: For a less toxic alternative we recommend: Remember to apply the glue to the metal first, then put it in contact with the styrofoam!
When gluing metal, it’s a good idea to clean it first with steel wool or sandpaper. (Rust never sleeps.)
Styrofoam is a plastic that has been whipped up like a milkshake and then hardened like that. That makes it easy. As with plastic, there are many different recipes for Styrofoam. They can contain any combination of styrene, urethane, neoprene, or vinyl. For this reason, choosing the right adhesive is not easy. For our testing, we used polystyrene, which is a composition of styrene, chlorodifluoroethane, and ethyl chloride, for those of you who are interested. The main things to consider when choosing an adhesive for styrofoam are:
Never use an adhesive that contains a solvent. It will erode the styrofoam and release all sorts of toxic fumes
Choose adhesives that are suitable for non-porous materials (remember that styrofoam is plastic and plastic is not porous).
Never use hot glue directly on styrofoam. There are some cases where hot glue is an appropriate adhesive, but it should be applied to the material you are gluing the styrofoam to and allowed to cool for a few seconds before touching the styrofoam. The glue is lost in the hole it burned, and toxic fumes are released when plastics are burned.
Remember that an adhesive is only as strong as the weakest material in the bond. Styrofoam breaks easily and has very low tensile strength. In our tests, if the styrofoam broke prior to gluing, the glue was considered strong enough.

How do you glue polystyrene plastic?
For bonding polystyrene, you can use one of a few different options. A poly cement, epoxy, or cyanoacrylate will form a sufficient bond on these items.
The Best Glues for Styrofoam of 2022
Plastic has come a long way from the early days of Bakelite to a variety of polymers that we see all around us every day. We’ve gotten so used to seeing plastic that we don’t even give it a second thought. Most people look at plastic and assume that all plastics have the same quality and properties. However, there are countless types of polymers, and each has unique properties.
So many of our everyday objects are made of plastic and from time to time these objects break. It could be a kid’s favorite toy, or maybe your lucky keychain, but the first thought in your head will probably be, “I’ll take some superglue and fix it later.” While cyanoacrylate (CA) glue can work, not all plastics are the same and the best methods for joining these plastics may vary depending on the type of plastic you are working with. Some plastics may require a plastic adhesive that contains a solvent based compound and others may require an epoxy based adhesive.
Determining the type of plastic using the recycling logo
Most if not all of us know the recycling symbol when we see it. It consists of three arrows forming a triangle. It’s all around us all the time, but have you ever looked closely and noticed that there might be a number in the middle or some other code underneath? This number or code tells us which plastic group the article belongs to. While these numbers and codes are primarily there to ensure that different types of plastic are properly recycled, they can also help you determine what type of adhesive you should purchase if you need to bond the material.
Choosing the right adhesive
There are a total of eight recycling codes for plastic. These codes indicate the exact material from which the product is made. Items marked with a 1 are made from polyethylene terephthalate (PET), while a 2 stands for high density polyethylene (HDPE). 3 is used for polyvinyl chloride (PVC), 4 means low density polyethylene (LDPE), 5 stands for polypropylene (PP), 6 stands for polystyrene (PS), 7 stands for other plastics and 9 stands for acrylonitrile butadiene styrene (ABS ).
Once you know what type of plastic you are dealing with, you need to choose the most suitable adhesive for the material. Category 1, 2, 4 and 5 plastics are very difficult to bond. Look for an adhesive labeled for polyethylene or polypropylene. However, certain Category 1 items may prove impossible.
Category 3, PVC, is most commonly used in plumbing. For gluing PVC there is a two-part primer and PVC solvent glue available at most home improvement or hardware stores.
Category 6 items are made of polystyrene. You have various options for gluing Styrofoam. A polycement, epoxy or cyanoacrylate forms an adequate bond on these articles.
Category 7 is a collective term for plastics that do not fit into the other categories. These plastics include polycarbonate and acrylic. For polycarbonate, an epoxy works best. To get the best result with acrylic, a solvent based acrylic adhesive is required. Cyanoacrylate can work depending on the project.
Category 9 is for ABS plastics. Although ABS solvent adhesives are available, they will warp the plastic to some degree. For best results an epoxy should be used. However, cyanoacrylate adhesive can also be well suited for this application.
The Infinity SuperTAC 500 Plastic Bonding Glue Sticks are one of the best hot melt options for plastic bonding. With superior heat resistance and adhesion to a wide range of plastics including PP, PE, PET and PV, the SuperTAC 500 outperforms many other plastic bonding glue sticks. The product’s economical price per pound is also unbeatable.
How to determine the type of plastic when there is no recycling logo
In some cases, a recycling logo and code may not appear on the item in question. In these circumstances, you need to make an educated guess or do a little research. There are a few things to consider that can help you determine the exact plastic you are dealing with. If the plastic is hard like a bucket or milk crate, it’s probably polyethylene or polypropylene. These plastics are almost impossible to glue unless you choose an adhesive specifically labeled for use with polyethylene or polypropylene.
Clear, brittle plastics such as imitation glass or CD cases are usually polystyrene. A polycement works best on these. Legos are made of ABS. If the mysterious plastic feels similar to a Lego brick, consider using an epoxy cement. It is important to note that solvent based adhesives can warp and alter the finish of the plastic. This is something to consider when looks are important.
Finally
When you need to glue plastic, it is important to determine what type of plastic you are dealing with. Plastic comes in many forms and knowing what type of plastic you are working with will help you choose the right adhesive for the job. If you still have questions and would like to speak to an adhesive expert, contact us. One of our knowledgeable team members can help you find the right adhesive for your application.

The best glue for polystyrene
The best glue for styrofoam really depends on what you are using the styrofoam for.
Expanded polystyrene (EPS), to give it its full name, comes in a wide variety of forms and applications. It is perhaps most notable as a key component of packaging, but more recently polystyrene has shown its use as a construction material. Its high insulating ability and light weight provide a versatile option for modern building practices.
In this blog, we cover the 4 best adhesives for gluing Styrofoam and look at the pros and cons of each.
PVA glue
PVA glue (also known as white glue or wood glue) can bond polystyrene to other porous materials such as wood, OSB, plywood, MDF, drywall, cardboard or fabric. And of course Styrofoam itself.
Advantages of PVA:
Ideal for many building materials
Water based, therefore low H&S risk
Very easy cleaning (with water)
Strong bond
Easy to spread with a brush or roller
Disadvantages of PVA:
Long drying time
Lower classes may not be waterproof
Our waterproof PVA Timbond is an excellent choice for working with polystyrene and is available in 1kg, 5kg or 25kg options or can also be purchased in bulk.
PU glue
PU adhesives come in two main formats: 1-component and 2-component.
1-component PU uses moisture to cure, while with 2-component PU you add an activator to initiate the cure.
The construction makes extensive use of PU glue to bond polystyrene to just about anything. This includes wood, most panel materials such as cement board and plasterboard, and metal and fiberglass panels.
Manufacturers of SIP panels like to work with PU adhesive because of its structural bond strength and waterproof properties. When gluing Styrofoam with 1K-PU, we recommend spraying the glued joint with water.
Advantages of PU glue:
Adheres to almost all building materials
1-component PU stretches easily, so it works well on rough, textured, or uneven surfaces
Sticks in humid conditions
Seriously strong bond
Adheres to non-porous materials such as metals, GRP and cement board
Comes in different applications. Cartridges and bottles are perfect for small areas and 25kg bulk drums for laminating applications
Available in different set times
Disadvantages of PU glue:
More difficult to clean. Use Solvent (Solvent 9)
Waterproof after curing
Some H&S risks / PPE may be required
Timbond 5917 PU is a specialty adhesive developed for a wide range of applications and panel fabrication including the construction of Structural Insulated Panels (SIPs) and building panels.
spray glue
Traditionally, the blowing agent in spray adhesives would melt the polystyrene, which of course isn’t ideal! Fortunately, today, specialty products use a different propellant, completely avoiding the problem.
These spray adhesives are very popular for insulation as they are very quick and easy to apply.
Spray adhesives are also useful for gluing large styrofoam blocks together for formwork or model making. For example, Timbond Insulation Adhesive is ideal for bonding Styrofoam to fabric, leather, carpet, foam, metal, hard plastic or plywood.
Advantages of spray adhesive:
Sticks to almost all building materials when clean and dust free
Very quick drying, no cramp time
Easy to apply – bonds large areas quickly
Disadvantages of spray adhesive:
Doesn’t work well with dusty surfaces
hot melts
Low melting point hot melts and pressure sensitive hot melts (applied via vortex applicators) – are used extensively in the manufacture of polystyrene insulated components.
Hot melt like Timbond H509 is a safe, fast and economical option that bonds to almost all building materials including plasterboard, correx, plywood and MDF.
Hot melt pressure sensitive adhesives are commonly used for packaging and boxes.
Advantages of hot melts:
Adheres to almost all building materials
Very fast drying
Very low cost per m²
Perfect for repeat applications
Disadvantages of hot melts:
Equipment often required
Limited open time for some hotmelts
So there you have it – a range of adhesives suitable for most applications, although of course there are more options.

The Best Glues for Styrofoam of 2022
Using the right glue for Styrofoam makes creating craft and hobby projects easier. The wrong glue on Styrofoam will not only create a poor bond, but some glues can even melt or dissolve this delicate material. A good styrofoam glue is safe to use on styrofoam, but it should do more than just make your project stick together. The top options are easy to apply, smell nice, and dry to an attractive finish. In addition, the best adhesives for Styrofoam ensure a better bond.
Hobby Styrofoam is a polystyrene foam that is made of plastic and contains air to make it light. While the two terms are often used interchangeably (including in this guide), most materials referred to as “Styrofoam” are solid polystyrene foam. “Styrofoam” is a trademark of polystyrene typically found in commercial settings. Many foam adhesives can work with either type.
Types of glue for styrofoam
Although several types of glue can be used on Styrofoam, the best products share the same characteristics. They are relatively uncomplicated and produce a clear finish with minimal fumes and odor. Multipurpose adhesives are useful for other materials, including cardboard, wood, glass, or metal. When purchasing styrofoam glue, remember that styrofoam is a plastic, which means any glue that contains solvents like acetone can cause it to dissolve.
craft glue
For simple craft projects at home, basic craft glue is usually more than enough. It is the most accessible and affordable option. Use craft glue to glue styrofoam to styrofoam, as well as to glue other common craft materials like cardboard, construction paper, and wood.
However, craft glue may not provide the strongest bond compared to a multipurpose glue or styrofoam glue, but is a good option for casual projects. A tackier, thicker white craft glue (quick-drying “tacky glue”) can help reduce sagging and mess when working with Styrofoam.
spray glue
Aerosol glues, available at many hardware or craft stores, are typically made for multi-purpose use around the home. Use them when gluing a variety of materials, including Styrofoam.
Spray adhesive covers a flat piece of Styrofoam much faster than glue from a squeeze bottle. However, spray adhesives are often less tacky than some adhesives (partially because they apply a thinner layer of adhesive). Spray adhesives are better suited for gluing large areas together, e.g. B. two styrofoam plates than for gluing two smaller points such. B. two styrofoam balls.
Low temperature glue gun
Glue guns are attractive because they can be used to glue a range of materials including paper, cardboard, fabric and wood; However, hot glue can damage styrofoam. Styrofoam has a low melting point, so take extra care when working with styrofoam and heat.
Use a low temperature glue gun to avoid damaging the styrofoam with heat. The lower the temperature, the better. If possible, apply the hot glue to the other heat-resistant material first and wait for the glue to cool slightly before attaching the styrofoam piece.
styrofoam
Serious hobbyists may want to use a special styrofoam glue called styrofoam glue, which is specifically designed to glue styrofoam. Styrofoam glue may be difficult to find, but it’s reasonably affordable. Those who frequently work with styrofoam, such as B. Craftsmen building styrofoam models may find it a reliable and effective choice.
Styrofoam glue is available at some hardware or craft stores. Some styrofoam glues are just for styrofoam (to glue styrofoam to styrofoam), while others are multi-purpose glues.
What to consider when choosing the best glue for styrofoam
Manufacturers make different types of glue for Styrofoam, but the best product depends on the needs and personal preferences of the craftsman. When deciding which polystyrene adhesive product to use in a project, consider the intended use, tack time, drying time, and whether the adhesive is waterproof.
purpose of use
Various types of polystyrene foams are used in settings ranging from building insulation to hobby model making. Expanded polystyrene foam (EPS) and extruded polystyrene foam (XPS) are the most common and most people refer to them as “Styrofoam”. Lightweight and usually white in color, EPS foam is used to make packaging peanuts, packaging materials, and lightweight craft foams. XPS foam, which is denser, is often used in more detailed models, e.g. B. in hobby and architectural building models. Many polystyrene-safe adhesives can be used with polystyrene foams.
When choosing a Styrofoam adhesive, consider the size, shape, and intended use of the foam. A thinner adhesive, such as A spray, for example, may work better for gluing large areas. However, for more detailed work, a thicker adhesive may be best. Also consider the intended use of the project – indoors or outdoors – and how much force the adhesive will have to withstand. Heavy duty or super strength options are available, as are adhesives for larger construction projects.
grip time
Different adhesives have different textures: some feel tacky immediately, while others take time to become tacky or develop a bond only after drying. For example, Styrofoam pieces can initially slide around when glued with a liquid craft/school glue, while hot glue can stick quickly. In this guide, “gripping time” refers to how long it takes for two glued pieces to “grip” or stay in place after gluing.
A tackier glue will help hold the styrofoam in place while the glue dries completely. Most products don’t advertise the exact stick time, instead using a few terms to denote a tackier adhesive, including “fast tack”, “fast set time” or “good bond strength”. However, do not confuse handle time with drying time.
dry season
The drying time (or cure time) refers to how long it takes for the adhesive to fully bond and reach its full strength. The drying time varies depending on the type of adhesive. Some styrofoam glue only takes a few minutes to dry, while others take 24 hours or more to cure. Hot glue dries in minutes. Sprays and multi-purpose glues usually take longer to dry, sometimes a full day. Construction adhesives can take days to fully dry.
For some projects, like model making, a shorter drying time is a necessity. No craftsman wants to wait a whole day between each assembly step. For projects with only one or two gluing steps, a longer drying time may not be an issue and could be a worthwhile compromise. For example, many construction adhesives take 24 hours or more to fully cure, but the result is a much stronger bond than hot glue.
waterproofness
Depending on the project, hobbyists need glue with additional properties. For example, use waterproof or waterproof glue for outdoor projects or to provide an extra layer of security. Waterproof adhesives do not dissolve when exposed to water. However, water-resistant adhesives degrade with exposure to water, but they don’t wash off as easily as non-water-resistant adhesives. Water-soluble adhesives can be removed with water, making them an excellent choice for crafts with kids.
Waterproof adhesives should not move when exposed to water. Using a waterproof glue will ensure the styrofoam will hold together even when submerged in water.

Tips for gluing Styrofoam together
Gluing Styrofoam together or to other materials is fairly easy with the right glue, making finding the right glue an important first step. Some glues don’t work very well with styrofoam and others can even melt or dissolve the foam. Make sure the glue can hold on styrofoam as well as on any other surface.
Always follow the product’s instructions for the best grip and pay attention to the manufacturer’s safety instructions. If necessary, clean and prepare the surface by removing loose pieces of Styrofoam, dirt and dust that may affect the adhesion of the adhesive. A thin, even layer of glue is usually sufficient. Because some adhesives stretch, using too much can cause them to leak out the sides. Although Styrofoam is lightweight, it can still slip and shift if the glue isn’t sticky enough to hold it in place. Hold the pieces together tightly until the glue has set.
Most adhesive products can be used more than once. Tighten the lid of the container to prevent drying out and store as directed.
