The kind of adhesive glue to use on foam
Foam is a delicate material that requires a specific kind of adhesive to ensure a strong and long-lasting bond. Note that the type of foam you are using will determine what kind of adhesive you should use. There are a variety of foam types that require different adhesives, so it’s important to do your research before beginning any project.
For closed-cell foams, such as polystyrene and polyethylene, cyanoacrylate (super glue) is an effective option. This type of glue dries quickly and creates a strong bond that can withstand harsh conditions. However, for open-cell foams like polyurethane and latex, contact cement or spray adhesive may be more suitable. These types of adhesives create a stronger hold on porous materials by seeping into the open cells and creating a firm bond.
Regardless of the type of foam you’re working with, always follow the manufacturer’s instructions when selecting an adhesive.
Does Rubber Glue Work on Foam?
For any crafting or DIY projects that involve foam, choosing the right glue can be a difficult task. Foam is a porous material that requires a specific type of adhesive for proper bonding. On the other hand, rubber glue is considered a heavy-duty adhesive that can bond various materials together.
Note, that rubber glue is a popular adhesive that has been widely used in the industrial sector for decades. It consists of natural or synthetic rubber mixed with solvents such as acetone or toluene. When applied to surfaces and allowed to dry, this adhesive creates a strong bond between them.
But what you really need to understand is that there are different types of foam such as polyurethane, polystyrene, and neoprene. Each has its unique properties which determine which glue will work best. Polyurethane foam is generally more flexible than other types of foam but may require an adhesive specifically designed for this material. Polystyrene foam is lightweight but can melt when exposed to certain chemicals in adhesives like rubber glues.
Now, when it comes to neoprene foam, it is a versatile material used in various applications such as wetsuits, sports gear, insulation, and even mousepads. This type of foam is known for its excellent insulation properties, flexibility, and water resistance. However, when it comes to bonding neoprene foam together or with other materials like metal or plastic, finding the right adhesive can also be a challenge.
One adhesive that’s often suggested for bonding neoprene foam is rubber glue.
In summary, all three types of foam discussed here, can be glued using rubber adhesives. However, you’d better test the glue before you do a full gluing exercise.
Can I use rubber cement to glue foam together?
Rubber cement has been a popular adhesive for many years. It is versatile, easy to use, and works well on numerous surfaces. However, when it comes to gluing foam together, rubber cement may not be the ideal solution. Foam is a lightweight material that requires an adhesive with strong bonding capabilities.
A glue stick can work well for small foam projects such as school projects or DIY crafts. However, for larger and more complex foam pieces like upholstery or soundproofing panels, a contact adhesive would be more suitable. Contact adhesives provide instant bonding and create a permanent bond between two materials by melting the foam slightly and bonding it together.
So if you are still asking yourselves this question, then while rubber cement can be used to glue foam together in certain situations, it may not provide the best results in all cases.
Effectiveness of Spray Adhesives on Foam
Foam bonding requires a reliable adhesive that can bond the foam without compromising its structural integrity. Spray adhesives are commonly used for foam bonding, but the question remains: Are they effective? The answer is yes, spray adhesives can be used for foam bonding, but the type of glue may affect the effectiveness.
Spray adhesives come in different formulations, such as solvent-based and water-based. Solvent-based spray adhesives may not be ideal for foam bonding because they can dissolve or melt the foam’s surface, resulting in weak bonds that break easily. On the other hand, water-based spray adhesives are more suitable for foam bonding because they have less aggressive solvents that do not damage the foam’s surface.
#1. Woodland Scenics Foam Tack Glue – Best Glue to Use
For those who are concerned with finding the best glue for foam, we think you should go with the Woodland Scenics Foam Tack Glue.
This is a nice, non-toxic, water-soluble glue that will not damage the foam. We like that it dries quite clearly and is very flexible. Best of all, we like it because it is specifically made to adhere to foam surfaces.
It is very rubbery and definitely not stiff like Elmers.
Additionally, there are not really any funky smells, the cleanup is really easy and it doesn’t get messy like some other brands. But most importantly, we just like how it forms a very strong bond with foam while being very flexible as well, which is quite hard to both achieve.
#2. Aleene’s Felt & Foam Tacky Glue
We think one of its standout features is that it simply has a nice strong hold. Although we don’t feel like it is better than that of Woodland Scenics mentioned above, it is at least on par.
Another thing you will likely notice when you try this product out is that it just dries really fast. This can be a good and bad thing.
The good part is that it won’t leave a mess everywhere and you won’t have any dripping. The bad thing is that you just have to work fast on your project.
#3. Gorilla Heavy Duty Spray Adhesive
We like how it forms a clear, permanent bond that is very moisture-resistant.
This is actually really useful if your projects with foam are going to be outdoors, where the weather can be unpredictable.
The bond is extremely durable and long lasting and will not deteriorate much even in really bad weather, extreme temperature changes, and extreme moisture such as at sea.
And best of all, it is a spray adhesive that dries clear and won’t discolor any of your foam. And with this spray, you won’t get too much mess and it will apply evenly.
Overall, Gorilla Glue is particularly effective on foam because it dries clear, creating an invisible bond that won’t detract from the aesthetic appeal of your project. It also expands as it dries, filling any gaps between the foam pieces to create an even stronger hold. However, it’s important to note that not all types of foam are compatible with Gorilla Glue. Polyurethane foams tend to work best with this adhesive.
#4. Loctite PL 300 Foam Board Adhesive – The Best Adhesive for Foam Board
The Loctite PL 300 is a pretty nice adhesive that is engineered specifically for foam materials. This is not generic super glue or some generic adhesive.
First and foremost, this is Loctite, which is a very well-known brand in this game. They have a solid history of making great glue products and can be found on the shelf of every retail store near you.
So the brand name and trust are already there. What about performance? We think the bond strength is incredibly strong, but you will have to wait a bit for it to settle and dry.
Also, it can get messy since it kind of squirts everywhere and you can’t exactly feel out the right amount to put. Also, it tends to smell more than other brands and you will need ventilation.
#5. Beacon Hold the Foam Adhesive
We like that it has an instant grab but also gives you time to reposition, so you can easily find the optimal bonding position for your projects.
Additionally, it doesn’t make as nearly as big of a mess as the Loctite PL 300 and it is a bit easier to apply because the bottle is just smaller and more precise.
All in all, this is definitely worth it to try out and if you have already tried out the brands we mentioned above and looking for something new, this is it.
Final words on the best glue for foam
There are a wide variety of adhesive choices out there for securely bonding foam. These range from hot glue (not discussed here) to aerosol spray adhesives.
The one that we liked the most is the Woodland Scenics Foam Tack Glue. It offers an easy-to-use formula that creates an invisible bond.
The Aleene’s Felt & Foam Tacky Glue works well with both felt and foam products. On the other hand, the Gorilla Heavy Duty Spray Adhesive is perfect for larger projects requiring a stronger bond.
