Top 5 Best Glues for Foam Crafts and Upholstery
1. Bob Smith Industries Foam Glue – Best for RC Planes
- Size: 1 oz.
- Designed specifically for foam surfaces.
- Bonds in 5-15 seconds.
- Also works well on fiberglass, ceramics, wood and plastic.
- Price: Check Price
Bob Smith Industries Foam Glue is an excellent, albeit expensive, glue designed specifically for foam. In addition to bonding foam it can also work equally well on ceramic, wood, plastic and fiberglass surfaces and dries in as little as 15 seconds. It’s even odorless so you won’t have to deal with any lingering smells after you’ve completed your project.
The biggest drawback is that it’s incredibly expensive for the amount of glue you actually get. Though it’s the best for styrofoam RC planes, you’ll end up spending quite a bit of money on glue if you plan on using more than 1 oz to repair any potential damages.
- Perfect for RC planes.
- Fast drying.
- Works well on foam, wood, plastic, fiberglass and ceramics.
- Only comes in 1 oz package.
2. Gorilla Clear Foam Glue – Best for Foam Boards
- Size: 3.75 oz.
- Resists water.
- Effective on wood, stone, metal, ceramics, glass and of course foam.
- Price: Check Price
If you’re looking for a foam glue specifically for bonding foam to glass, then the Gorilla Clear Foam Glue is the choice for you. In addition to being incredibly strong it’s also non-foaming and water resistant which makes it a perfect candidate for foam surfaces that may be subject to condensation. It’s also clear so it won’t hurt the aesthetics after you’re done applying.
Application is simple – if you’re using it non-porous surfaces just make sure to lightly dampen the surface with water before applying. Then glue the two pieces together and clamp or apply pressure to the surface for 2 hours and you should be good to go. Keep in mind it’s recommended to wait 24 hours before the glue fully cures.
Unfortunately this glue takes quite a long time to dry. It recommends 2 hours but we recommend you wait a full 24 hours before you unclamp it allow it to fully cure. While the glue is clear it does tend to dry a bit stringy if you don’t let it fully cure before unclamping so the more time you can give it to cure the better.
- Perfect for foam boards and sheets.
- Water resistant.
- Very strong glue if you let it fully cure before use.
- Doesn’t work with polypropylene or polyethylene plastics.
- Takes a minimum of 2 hours to dry and 24 hours to fully cure.
3. Aleene’s Felt and Foam Tacky Glue – Best for Foam Sheets
- Size: 4 oz.
- Very thick.
- Dries strong.
- Designed specifically for foam & felt.
- Price: Check Price
While Aleene’s foam glue is specifically designed for felt and foam it is also pretty effective on things like jewels and fabric. Keep in mind that unlike many of the other glues on this list, Aleene’s is tacky and has the consistency of something like Elmer’s glue. Keep in mind you’ll need to give this glue a solid two hours to fully dry so take that into account before use.
While the product boasts that it dries clear, we noticed that isn’t really the case most of the time. You can see some minor discoloration but if you use a very small amount it shouldn’t be noticeable. Still, the consistency is a bit thick which makes it challenging to actually get out of the container and might be a bit too thick when you compare it to the other foam glues on this list.
- Perfect for gluing foam and felt together.
- Great for a variety of arts and crafts projects.
- After drying it forms a strong adhesion.
- Difficult to squeeze out of the bottle.
- The consistency is too thick.
4. 3M 74 Foam Spray Adhesive – Best for EVA Foam
- Size: 16.9 oz.
- Applies adhesive via aerosol spray.
- Quick bond time (from 15 seconds to 30 minutes).
- Recommended for upholstery, installing acoustic panels and foam lamination.
- Price: Check Price
3M’s adhesive spray is a great choice specifically for EVA foam or acoustic panels that require more adhesive and a stronger bond. The aerosol can dispenses a lace pattern that is specifically designed to optimize the adhesive bond and prevent even high stress pieces from coming undone. While 3M boasts it can dry in as little as 15 seconds, you’ll want to give it at least 30 minutes to fully cure.
We recommend this glue specifically for larger products like gluing EVA foam as it comes in much larger quantities than the other options on this list and maintains the bond over time.
While the aerosol dispenser may make it quicker to apply, there are a few drawbacks. For starters, it can become difficult to control the spray and quantity dispensed. The glue itself works excellently, but you may have to deal with leaky heads and an uncontrollable spray. That being said, it’s still hands down the best choice for larger surfaces like EVA foam pads.
- Perfect for EVA foam.
- Excellent for larger projects.
- The aerosol spray is easier to apply.
- Dispenses a clear adhesive.
- Fast bond time (15 seconds to a maximum of 30 minutes).
- The aerosol head may leak over time.
- Can be difficult to control the quantity dispersed.
5. 3M Hi-Strength 90 Spray Adhesive – Best for Bonding Non-Porous Foam Boards to Concrete
- Size: 12.23 oz.
- Adjustable aerosol spray.
- Heat and moisture resistance.
- Works well on laminate, wood, concrete, metal and plastics.
- Price: Check Price
This high strength adhesive spray is the best choice specifically for bonding non-porous foam to a variety of surfaces, including concrete. It also boasts moisture and heat resistance making it a perfect option for permanent bonding even in a non-climate controlled area. The nozzle is also adjustable which significantly helps with the application process.
Unfortunately the can must be inverted to spray consistently, so you won’t be able to spray on overhead surfaces very well. You’ll also need to keep the aerosol head clean as if it gets clogged the adhesive spray will come out in globs and provide very poor coverage. That being said, if you need an adhesive spray for a variety of surfaces this is the choice for you.
- Perfect for gluing non-porous foam to concrete.
- Adjustable nozzle to control the amount of adhesive dispensed.
- Very high strength.
- The can must be inverted to spray effectively.
- Must keep the aerosol sprayer clean or the adhesive will come out in globs.
The 5 foam adhesives that we’ve reviewed above are easily the cream of the crop. And of those 5 the Bob Smith Industries Foam Glue is our all around choice for the best foam glue.
On the other hand if you need a foam glue specifically designed for foam boards then we’d suggest the Gorilla Clear Foam Glue. Alternatively if you’re shopping specifically for rc planes then you can’t go wrong with the Bob Smith Industries Foam Glue.
There is a great deal of variety among foam glues and it’s worth comparing the requisite features before making a purchase. That’s why we wrote this buyer’s guide so you can determine which elements are most important before you buy a foam glue.
Before making a purchase you’ll need to make sure that the glue or adhesive you choose is specifically designed to glue your foam piece onto whatever surface you require. If you plan on gluing foam to foam this doesn’t really apply, but if you want to permanently apply foam onto concrete or wood then be sure your product choice is rated for that particular surface.
The durability of glue varies pretty dramatically from product to product. If you plan on permanently bonding two pieces together you’ll want to be sure to select a higher strength product. If you’re just doing a simple arts and crafts project then you probably won’t need a heavy duty option, but for interior foam installation or upholstery you’ll want to be sure to pick something that can stand up to wear and tear.
There are two general methods of application: spray-on adhesive and squeeze glue. Squeeze glue is the one you’re probably already familiar with if you’ve ever used standard Elmer’s glue, but if you plan on bonding larger surfaces you’ll want to go with adhesive spray as it’s much quicker to apply.
Drying and Cure Time
Another big variable when selecting glue is the bond time. Generally speaking, the bond time takes anywhere from 15 seconds to 30 minutes but you’ll want to give it up to 24 hours to fully cure. If you want to be extra careful we’d recommend doubling whatever the manufacturer’s recommended cure time before use so you don’t compromise the quality of the adhesive.
Heat & Water Resistance
In non-climate controlled areas you’ll want to be sure that the glue you choose is specifically designed to be heat and moisture resistant, otherwise the glue will become damaged over time and you’ll need to re-bond it to the surface.
Be sure to check whether or not the manufacturer offers a warranty on the item you intend to purchase. While Amazon should cover broken or defective items upon delivery, it’s up to the manufacturer as to whether they will provide a replacement after it’s been used. Compare different foam glue sellers to see if any of them will offer replacements in the event it breaks from normal use.
Even if everything works properly, you may discover you’ve ordered the wrong foam glue for your needs which may require a return. Be sure to check with the vendor before purchasing to see if they will allow a return and if so, under what circumstances.
Shipping is easily one of the most annoying costs associated with making online purchases. Be sure to compare the shipping costs to your location prior to making a purchase so you don’t end up spending more than you bargained for.
Frequently Asked Questions
Which foam glue is the cheapest?
If you’re shopping for the lowest priced foam glue you can find then we recommend the Aleene’s Felt and Foam Tacky Glue. Of all the foam adhesives we’ve reviewed, none of the others can beat it’s price.
How do you glue foam to foam?
All of the glues we’ve reviewed above can effectively bond foam together. We recommend an aerosol spray for larger sheets as it makes it much more convenient to apply. Once applied, simply compress the two pieces together and wait for the glue to cure and you should be good to go!
Does glue stick to foam?
Standard glue doesn’t work very well on porous foam surfaces which is why you’ll need to choose one of the products above. If you use the incorrect glue on open or closed-cell foam then it could cause the foam to break apart and permanently damage the surface.
Does Elmers Glue work on Foam?
For simple arts and crafts project it can potentially work but we wouldn’t recommend it. It tends not to dry clear and can damage the foam surface if it’s too porous. We strongly recommend picking up one of the glues we’ve reviewed above if you plan on gluing foam.
