How to glue styrofoam

The question around which is the best glue to use on styrofoam or polystyrene is a common one and there are a number of glues out there that claim to do the job. It can be confusing though trying to figure out which glues are going to work the best.

Terra over at was getting so frustrated with all the mixed information out there that she decided to do a test of her own.

Her mission was to find the best glue to use on styrofoam and polystyrene and these were the contenders:

  • Loctite PL300 Foamboard Glue
  • Super 77 Spray Adhesive
  • Glidden Gripper
  • Foam Fusion
  • Gorilla Glue
  • Great Stuff
  • StyroGoo

She used both scratched and unscratched surfaces in the tests and compared the results after 24 hours and then after 48 hours.

Have you had any experiences with styrofoam or polystyrene glues that you would like to share? Then please let us know.

You can also use silicone caulk or expanding spray foam as the adhesive to secure the rigid foam to the metal. After the adhesive dries completely under the foam insulation, apply seaming tape over all joints between the boards. If desired, you can apply silicone caulk between the joints instead of using seaming tape.

How to glue styrofoam

Today is America Recycles Day, which you can learn more about recycling here . We wanted to take this opportunity to learn something cool about one of the most heinous landfill residents: styrofoam. This lightweight convenient insulating material has found many uses, from takeout containers to disposable coolers. Unfortunately, to go along with all of its good qualities, it has one bad one: it doesn’t degrade naturally. This means that when it goes in the trash, it will stay there for a very long time. In addition, styrofoam is about 95% air, each pound that is disposed of will be taking up a lot of space–possibly up to 30% of the total volume–in our garbage for the foreseeable future.
Fortunately, not everyone is resigned to this fate. Instead, people have been trying to come up with a better way to deal with this. One of these ways uses acetone . Acetone is an organic molecule made up of carbon, hydrogen, and oxygen, and is the simplest member of the ketone family. On the right is a picture of acetone at the atomic level.
Most of the uses of acetone revolve around a single property: it is an excellent solvent. This means that it does a great job of dissolving many different kinds of molecules, making it useful as a cleaning agent in chemistry labs and a remover of nail polish.

Styrofoam is made of polystyrene, which in itself means a chain of styrene. Styrene is a relatively simple organic molecule that can easily bind with itself. When it comes in contact with acetone, the polystyrene chains fall apart. However, the acetone doesn’t actually dissolve the styrene molecules. If it did, all of the styrofoam would disappear into the acetone, but instead we end up with this.

Depending on your point of view, this probably looks like some combination of gross, scientific, and fun. Additionally, it is also useful. Using solvents like acetone to break down styrofoam can repurpose it to being a rather useful adhesive. Being able to use styrofoam as a glue is a terrific alternative to having it fill up or landfills.
Please don’t rush out and try to do this on your own, as acetone is dangerous and also not the right chemical to do this properly. To learn more about this method go here .

UHU Por adhesive is my favorite for foam to foam or foam to wood. Gorilla glue was good in places, also epoxy, hot glue, even wall board ‘No Nails’ type adhesives. Any adhesive used on foam is only as good as the foam. Some foam surfaces will break away from the rest of the foam much easier than others.

Additionally, can you screw into foam insulation? Using washers in conjunction with screws and nails is important. Because the surface of foam insulation board is porous, the head of a nail or screw will go right through the foam board without a washer. A nail or screw is driven directly through the disc, through the foam board and into the plywood.

Additionally, how do you attach Styrofoam insulation?

  1. Caulk all the seams between ceiling and rim joists with silicone caulk.
  2. Measure the height of the wall from the floor to the ceiling.
  3. Apply adhesive to the back of the rigid foam insulation panel.
  4. Place the panel against the wall, and push firmly.

What kind of glue can you use on Styrofoam?

The best glues to use on Styrofoam are the actual Styrofoam glues such as UHU Styrofoam glue, Weldbond and 3M 77. Styrofoam glue comes in both tubes and spray. The adhesive spray, like 3M 77, makes creating projects easier and without the mess. With 3M 77, the glue dries fast and provides permanent bonding.

How to glue styrofoam

Metal heats and cools quickly without protective insulation. This causes any object made of metal to become extremely hot when left in the sun or extremely cold when left outside in colder climates. Adding foam insulation to one side of an object will lessen the amount of heat transfer between the areas separated by the metal.

Measure the length and width of the metal with a tape measure.

Cut a piece of foam insulation to the required length and width using a sharp knife. A knife with a dull blade will cause the insulation to tear along the cuts and reduce its ability to cover the surface of the metal completely.

Sand the surface of the metal that will receive the insulation vigorously with 400-grit sandpaper. Stop sanding when the surface is covered with light, even scratches.

Spray aerosol solvent cleaner on the sanded metal surface in long, even strokes as you depress the can tip. Wipe the metal with a clean rag to remove grease, oil and other debris from the area. Allow the area to dry for 15 to 20 minutes.

Hold the nozzle of an aerosol contact adhesive 4 to 6 inches away from the metal. Depress the can tip. Spray adhesive using long, even strokes until you have a medium coat of glue on the metal. A medium coat of adhesive will shade the metal with the color of the glue, whereas a thinner coat will texture the metal and a thicker coat will block out any signs of the metal beneath the glue.

Allow the glue to dry for 10 minutes or until it feels tacky to the touch.

Align the cut piece of foam with the glued metal. Press the foam firmly to the metal. Move your hands along the surface of the foam until it sits solidly against the metal to create a permanent bond between the two materials.

How to glue styrofoam

Foamies have led us to new ways of building and flying model airplanes. They allow us to assemble a plane in hours rather than days or weeks. Because they involve very little investment in terms of money and labor, we no longer need to fear pushing our flying skills to the limit.

The procedures followed for building with foam differ from those used when working with balsa. For example, there are various ways to hinge the control surfaces, and the method you choose will depend on the type and thickness of the foam. Let’s look at a few hinging techniques.


The Dremel tool is perfect for drilling holes in the control surface for Robart Hinge Points.

The first step when hinging any surface is to bevel the edges to be joined. If you use thin foam for your plane, you might not need to do this; simply hinge the surfaces.

Most foamies need beveled edges at the hinge line. Use a sharp hobby knife and a metal ruler to do the cutting. Put the ruler along the edge of the foam surface and, holding the knife at a 45-degree angle to the ruler, make one continuous cut; draw the blade from one end of the surface to the other. Have some type of cutting mat underneath the foam so that your cut is clean. A sharp knife is very important for producing a clean edge that’s ready to be hinged. A dull knife will leave a jagged edge that you’ll have to sand smooth.

You could also use a sanding block to bevel the edge. I like Great Planes’ Easy-Touch Bar sander with 150-grit sandpaper. I put the edge to be beveled at the edge of the workbench and then drag the bar sander across it at a 45-degree angle. Work across the edge until the entire surface is beveled correctly.

Charger RC’s Super Beveller (introductory price: $5.99) can handle foam of up to 5/16-inch thickness. Pull it along the edge of the surface to be beveled from one end to the other; the result will be a perfect cut every time.


Make a bevel in the control surface by using a metal ruler and a hobby knife.

Clean surfaces ensure that the hinge material will bond solidly and last for the life of the plane. Foam is sometimes slightly oily or dirty, so clean it to guarantee a secure bond. A quick wipe of rubbing alcohol cleans foam without destroying it.

Then be sure to let the foam dry completely before you hinge it-especially if you use tape as a hinge material.

Another way to ensure a good bonding surface for tape hinges is to dab thick, foam-safe CA onto the surface where the tape will go. Wrap plastic wrap around your finger and spread the CA over the surface. Then lightly spray on CA accelerator, clean off the excess accelerator with alcohol, and allow the surface to dry. It will then be ready for the tape hinge.


The Super Beveller is a new tool from Charger RC. It makes beveling the edge very easy to do.

Use foam-safe CA to make a thin layer of glue on the foam where the hinge tape will go. This makes for a smooth, solid surface for the tape to bond to.

Clear packing tape seems to be the most popular hinge material. It’s readily available, it sticks to surfaces very well, and it’s inexpensive. Also good is clear first-aid tape; it’s quite flexible and sticks well to control surfaces.

I put the two pieces to be hinged on a flat surface and line them up in their proper positions. I keep them in place with small weights such as beanbags. I like to keep a small gap (1/16 inch or less) between the two surfaces at the hinge line to allow complete 3D movement. I put the tape across the two surfaces with the hinge line along the tape’s center. After attaching the tape, I use a balsa stick to press out all the air bubbles and further strengthen the hinge bond. I flip the piece over, weight it down again and put tape on the other side; I make sure that the top and bottom pieces of tape stick together at the 1/16-inch hinge-line gap.

You can use CA hinges on foamies as long as you meet certain conditions. The foam should be thick enough for you to bevel a 45-degree angle on both the top and the bottom edges of the control surface and still have a 1/16- to ?-inch-thick flat edge. Cut your hinge slots with a sharp hobby knife, and insert the hinges just as you do when you hinge a balsa plane. Put five or six drops of foam-safe, thin CA on both sides of the hinge at the hinge line. Foam does not have the same moisture content as balsa, so it will take the CA a while to cure; let it do so overnight.

Robart Hinge Points are also good for thicker foam. Start by measuring the positions of and drilling the holes for the hinge points. I drill holes in foam with a Dremel tool. A Dremel spins the bit faster and is easier to control than a regular drill gun.

Epoxy works well for the hinges, and polyurethane glue is another good choice because it expands around the hinge as it dries. This glue requires moisture to cure, so wet the hinge point before you push it into the glue-lined hole. Whether you use epoxy or polyurethane glue, you should protect the hinge “knuckle” with oil or petroleum jelly. Polyurethane glue will expand out of the glue joint and onto the hinge “knuckle,” so let it dry before you attempt to remove the overflow.

Synthetic foam and silicone are good partners. The silicone glue is an adaptable bonding and sealing adhesive that allows you to manipulate foam rubber as the glue dries. Silicone glue works best on silicone rubber. It is fairly easy to obtain at hardware or big-box home improvement stores.

Additionally, can foam be glued together? Adhesives for foam are specially made to function in products used for comfort and support without changing their qualities. When gluing foam, apply adhesive to both surfaces evenly, and wait a few seconds for the glue to get tacky. Once you’ve properly aligned your cut foam, compress it together as firmly as possible.

In respect to this, what is the best adhesive for foam?

  • Original Gorilla Glue: This glue is sold at most stores and comes in either brown or clear.
  • 3M 30NF Green Fastbond Contact Adhesive: This glue is also referred to as the Green Glue, the 30NF Green Fastbond Contact Adhesive is a reliable brand.

Does Gorilla Glue work on Foam?

The same serious strength you expect from Original Gorilla Glue, in a dries white, faster formula. White Gorilla Glue is a 100% waterproof glue, safe for indoor and outdoor use and strong enough to stand up to the elements. The white glue easily bonds foam, wood, metal, ceramic, stone and much more!

Cyanoacrylate (super glue) works very well. It slightly melts the styrofoam in addition to bonding it.

Why does superglue dissolve Styrofoam?

Super glue and other adhesives contain some organic solvents (e.g. acetone, ethyl acetate). Styrofoam is made from thousands of styrene molecules linked together. Styrene by itself really wants to dissolve in these organic solvents, but since so many of them are linked together it can’t because it’s simply too big.

Can I use super glue on foam?

Super glue will only negatively impact the interior foam, but should bond with the exterior paper. You can indeed coat foam with glue. (I would suggest wood glue) You can water it down a bit and put on a good even coat and then let dry.

  • Cyanoacrylates – All Permabond cyanoacrylates bond well to polystyrene.
  • Two component epoxies bond well to polystyrene.
  • UV Curable – UV Curable adhesives are an excellent choice for bonding polystyrene.

Can I use a glue gun on Styrofoam?

Never use a hot glue gun when it comes to gluing Styrofoam. As Styrofoam is made from plastic, the hot glue gun can actually cause it to melt, potentially damaging your designs. Hot glue guns should only be used to attach materials which are not affected by heat.

Can I use wood glue on Styrofoam?

Don’t use a material-specific glue. When it comes to gluing Styrofoam, you’ll generally want to stay away from glues that are specifically designed to work on certain materials other than Styrofoam (e.g., wood glue, fabric glue, glues and epoxies used for construction projects, etc.).

What paint can I use on Styrofoam?

Water based paints or acrylic craft paints are the best to use on Styrofoam. Water based paints, specifically poster paints, work well with younger kids as they can get a really good and thick coverage of paint on the polystyrene shape. They will need a little longer to dry though.

What can you seal Styrofoam with?

It is a liquid urethane plastic. You mix parts A and B together and after 10-20 minutes it hardens into a smooth thin plastic coating. Brush it or pour it onto your styrofoam sculpture, let gravity do it’s job and the liquid plastic will seal the styrofoam and thin itself as it flows downward, over the sculpture.

Can you spray Flex Seal on Styrofoam?

The aerosols in the spray can version (Flex Seal) will melt the styrofoam. HOWEVER, the primary rubberizing agent in Flex Seal is perfectly safe. If you are in a pinch you can spray it in a cup, wait about 30 seconds for the aerosols to evaporate, and then paint it on.

How do I make Styrofoam paintable and smooth?

PAINT IT! Most spray paint and acrylic paint will work well on Styrofoam™ brand foam. For a smooth surface, apply paper mache, plaster or joint compound as a coating before painting. For easier handling when painting, insert a toothpick or skewer into the foam shape to use as a handle.

How do you seal acrylic paint on Styrofoam?

You can use a regular craft sealant such as Mod Podge, or you can target the styrofoam specifically and use something like Foam Finish. Apply the sealant using a foam brush or regular paint brush and then let it dry completely before painting the styrofoam.

How do you seal and harden Styrofoam?

You don’t need to rely on messy fiberglass resin to harden your Styrofoam. Simply use a two-part liquid polyurethane hard-coat system.

How do you keep Styrofoam from flaking?

Wrap tape around the Styrofoam to create a protective barrier. Clear packaging tape works well if you want to preserve the original color of the Styrofoam, but masking tape can be used if you aren’t concerned with the appearance. Regardless of the tape you use, make sure it lays flat against the Styrofoam.

Will Mod Podge melt Styrofoam?

Wondering if you can Mod Podge on Styrofoam? The answer is yes, you can!

How do you protect styrofoam from the sun?

Polyurea is a coating that can be used on any foam props, signs and projects. It protects the foam shape from weather, water, sun, and humidity, age and break damage.

Can Styrofoam melt in the sun?
