This transparent glue is a flexible adhesive and does not deteriorate over time. So, once the adhesion is created, you are good to go!
When it comes to the working process, this glue works in a bit unorthodox way. You need to apply the glue on the surface, then spread evenly to rest 10-20 minutes. After the resting period, you need to put both surfaces together to get a perfect flexible bind.
This waterproof glue is made in Germany and can be used for bonding Styrofoam to other surfaces like plastic, wood, metal, paper, glass, etc. So, you are not just restricted to gluing Styrofoam alone, rather you can go more creative with a wide range of choices.

Best Glue for Styrofoam Buyer's Guide
When purchasing the best Styrofoam glue for craft projects, these are some key things that you must consider. These checklists will help you not to buy a product that is not for styrofoam applications.
Everything that serves multiple purposes is better than those that serve only one purpose. When you purchase glue for Styrofoam, you’ll find that some glue will remain in the pack after the usage. Unless you are doing crafts regularly, these will be wasted. For reducing the wastage, you should pick a glue that can be used on other surfaces also.
2. Non-toxic Glues
Low-quality glues are highly adhesive but toxic because of the usage of harmful chemicals. There are ways to make the glue highly adhesive yet non-toxic. When you plan to buy some, remember to check the materials. You should always pick the non-toxic glues for avoiding future skin irritation.

3. Glue Color
Color is an important factor when it comes to arts and crafts. No one likes to see a color difference because of the glue. So, pick a glue that dries clear so that you can apply desired paint on the styrofoam.
Picking up the clear glues has other benefits too. You will not notice that there was a gap and two Styrofoams were attached to get the surface big enough. If there is no glue sticks with clear color, try to find white glue in arts and crafts store.
4. Drying Time
No one loves to wait. Neither I nor you! So, a fast-drying glue is always preferable over a slow drying product. But try to ignore super glues. Let me explain why-
When doing crafts with Styrofoam, you will need to position one on the other. Super glues dry and binds instantly allowing no time to fix any minor mistake. So, getting a glue that dries in around 10 to 30 minutes is the best for Styrofoam.
5. Perfect Adhesion to Polystyrene
As we have recommended above to pick a glue that adheres to most of the surfaces. But remember, you are purchasing the product for applying on polystyrene. So, the product must perfectly bind with the Styrofoam. The best way to know that is to read the product label and description. That should indicate where can you use the product, and where not.
6. Ease of Application
Some cheap products in the market are not easy to use. You need to put a lot of effort to make things happen with those. For doing some creative work, a cool and calm mind is the key and hard to apply products will interfere with your mood.
So, pick a product that can be applied precisely without any interruption.
7. Durable Adhesion
As you are gluing things together, the object must be to bind the surfaces permanently. Fast drying and permanent adhesion is a must for a product that is made for Styrofoam. I will not be pleased to see foam coming out of the surface after a few days, neither you!

How to Apply Glue on Styrofoam
Styrofoam is a great material that can be used for many things. It's lightweight, inexpensive, and easy to cut into shapes! One of the most common tasks associated with styrofoam is gluing it. This section will go over how to properly glue styrofoam using hot glue guns and other styrofoam adhesives.
Before you start gluing project, make sure to gather essential tools and supplies so that you don't need to find them in the middle of the process. Here are the things you need-
- Styrofoam that you will glue
- Adhesive you're going to use
- Soft Bristle Cleaning Brush
- Low strength tap
Pick the Right Glue
The first step is to pick the right type of glue. There are many different types of styrofoam adhesives that you can choose from, and the one you pick will depend on what your project is. For instance, if you're gluing an object onto a flat surface then contact cement or hot melt adhesive might be better for you than something like foam-tac which would need to go in between layers.
Avoid using material-specific glues or plastic solvents on styrofoam as these adhesives can change the shape of the styrofoam.
Clean the Surface
Now, you need to clean the gluing surface with a soft-bristled cleaning brush to get rid of any dust, dirt, or oil.
Gloves are also recommended because the adhesive will stick to your hands very easily and then be transferred onto other surfaces that you come into contact with. If you don't use gloves then make sure to get them as clean as possible before starting work again.
Apply the Glue
After cleaning, start applying this point, you need to apply the glue around the edge of the styrofoam panel.
The area should be covered with a thin layer that is about half as thick as your fingernail and not too much thinner than that.
If it's nice and even then use a wet paintbrush for this process because if it dries unevenly then you'll have trouble fitting panels together afterward. Now leave this adhesive to dry while cleaning up any excess from edges or surfaces near where you were working so that they don't become contaminated by what might now be an unsuitable material.
Since styrofoam glues take time to dry out, you need to use low-strength tape to keep the panels attached. Otherwise, you may risk ruining things. Don't use high-strength tape so that you can easily remove the tape without harming the styrofoam panel.
Leave it to Cure
After the application is done, it's time to let the adhesive dry. This is an important step because if it doesn't, you may need to follow the process again to attach the styrofoam panels.
The curing process takes around 24 hours, depending on the adhesive you used and weather conditions. So, avoid touching pieces until tomorrow morning. Afterward, make sure you remove the tape carefully.
Since styrofoam is not a strong material, gluing it won't guarantee that you can abuse the surface. Handle carefully not to break the piece again.
Styrofoam is an affordable material to give a shape according to your creative thoughts. For making things easier, Styrofoam glues are needed.

Frequently Asked Questions
What kind of glue can be used on Styrofoam?
It's important to use the correct type of adhesive when working with foam boards because most adhesives will not adhere to this material. Hot melt glue is often the best choice for attaching foam boards together, but it must be used in conjunction with a release agent such as wax or Teflon.
Clear silicone adheres well and can work without using any type of release agent if desired. Clear adhesive and fabric glue also works on polystyrene sheets, but it may not provide as strong of a bond.
Styrofoam glue is also available and can be used just like hot melt glue, but the drawback to this type is that it becomes too stiff with age, making foam board pieces difficult to manipulate.
Is Gorilla Glue good for Styrofoam?
Gorilla Glue is an adhesive that works on both Styrofoam balls and numerous other surfaces. It will work as well or better than the usual hot melt glue when working with foam board, but it does not have a release agent built-in so you must use something like wax or Teflon to keep it from sticking too strongly. The glue bonds well and can work without using any type of release agent if desired.
What kind of glue will not melt Styrofoam?
It is possible to use other types of glue on Styrofoam, but these will not be as durable and may melt or warp the foam. It's best to stick with hot melt adhesive because it adheres well, resists moisture, and does not tend to distort the shape of styrene pieces when limbs are put in contact with them.
Can I glue Styrofoam to other materials?
Styrofoam does not work well with all types of adhesives. The type of adhesive you choose should be specifically designed for use on styrene pieces, and often it will say "styrene-safe" or "no foam board." Some plastics can melt Styrofoam, so it is best to stick with hot melt adhesive.
Does Super Glue Work on Styrofoam?
Super glue is not recommended to be used on Styrofoam because it usually melts the foam.
Can Liquid Nails be used on Styrofoam?
Most liquid nails for Styrofoam may not work well because it does not want to stick.
How do you glue wood to styrofoam?
You can use any type of glue that works on both the wood and styrene. If you want to make sure your bond is strong, superglue or epoxy work well for attaching Styrofoam to other materials. Re-positioning a glued joint should be done with caution because hot melt adhesive may not have enough time to set.
Will Mod Podge melt Styrofoam?
Mod Podge is water-based and should not be used on Styrofoam because it will most likely melt the expanded polystyrene foam.
Can I use a glue gun on Styrofoam?
You should not use hot glue guns on Styrofoam because it will dissolve styrofoam. Use basic craft glue instead or go with low temperature glue gun.
How do you seal Styrofoam?
Styrofoam is a porous material that should not be sealed because it will trap moisture. You can seal any other surface with spray-on, paint or stain in the same way as you would on wood.
How do you glue glass to styrofoam?
You can attach glass to Styrofoam by using strong super glue or epoxy.
How do you cut styrofoam?
Styrofoam should not be cut with anything other than an electric saw because it will crumble and break apart. You may use scissors on the edge of Styrofoam to trim off excess material.
How do you fix broken Styrofoam?
If you have a broken Styrofoam, it is best to throw away the piece. Because it's almost impossible to bring it back to its original shape once it is broken. However, you can try once by applying right glue or spray adhesives to bring back its original shape. This will be only possible if the styrofoam has been broken into two clean pieces.
How do you keep Styrofoam from flaking?
To keep Styrofoam from flaking, you should seal the edges of your foam with glue or another type of adhesive. You can also use a spray varnish to coat both sides and protect it.
How do you stick styrofoam to styrofoam?
Styrofoam is a porous material, and it will not adhere to itself. To stick styrofoam together permanently you need adhesives such as hot glue, wood glue or spray adhesive.
