Speaking of the best adhesive for foam board to concrete, it is a task that sounds simple enough but can quickly turn into a sticky situation if you use the wrong adhesive. Believe me, I’ve been there, frantically trying to pry foam pieces off the garage floor after using glue that just didn’t have the grip.
So I’ve done the dirty work of testing out the top contenders for best foam-to-concrete adhesive. I squeezed, stuck, peeled, scraped, and weighted to find the glue that passed my adhesion tests with flying colors. No foam bits left behind on the concrete here!
Stick with me as I break down the need-to-know on three foamboard types of glue that have the strength and staying power to hold on tight to concrete. I’ll give you the sticky details on how they performed in my experiments, so you can decide which is the best fit for your projects. Let’s get stuck in!
What Are The Requirements to Be the Best Adhesive for Foam Board to Concrete?
Consider these features before buying the adhesive to bond foam board and concrete (you might also be interested in the best adhesive for foam board to bond metal)
|Why This Feature|
|Strong Bond Strength||Creates a robust, durable bond between the porous foam board and rough concrete surface|
|Flexibility||Accommodates expansion/contraction of foam board and concrete at different rates due to temperature changes|
|Moisture Resistance||Maintains strong bond despite concrete’s tendency to absorb moisture and condensation|
|Quick Setting/Curing||Sets and cures rapidly to firmly fix foam board in place|
|Low VOC/Low Odor||Has low VOCs and odor for better indoor air quality|
Strong Initial Tack 🛍️ SikaBond Construction Adhesive
The first time I used SikaBond Construction Adhesive was for attaching Styrofoam boards to an aluminum garage door. The bond it created was impressive, and I was thrilled with the results. The adhesive held the boards securely in place, giving me peace of mind that they wouldn’t come off easily.
Encouraged by my initial success, I decided to tackle a more demanding project involving stucco. I had heard from other users that this adhesive was the best choice for such applications. With confidence, I set out to bond marble on entrance block stuccoed columns. The adhesive performed flawlessly, providing a strong and durable bond that exceeded my expectations.
Not only did the adhesive work well for stucco, but it also proved effective for other applications. I had a metal roof project where I needed to secure pavers to cap a column. Using the same adhesive, the process went smoothly, and the results were excellent. The pavers remained firmly in place, with no signs of sagging on the vertical surface.
In terms of longevity, this adhesive has proven to be reliable. I used it to seal roof jacks on a metal roof, and it has remained pliable and durable for months after application. The bond it creates is strong, and I have complete confidence in its performance.
However, not all experiences were perfect. There was one instance when the shipping box caused minor damage to the product. Despite this setback, the adhesive itself was not affected, and I was able to use it without any issues.
One important aspect to note is the applicator choice. When I initially used a manual caulk gun, I found it challenging to squeeze out the adhesive. It was a bit too thick for this type of gun, and it started leaking from the nozzle. I realized that a mechanical caulk gun would have been a better option for this particular adhesive.
Easy alignment 🛍️ Loctite PL300 Foamboard Adhesive
Finding the right adhesive that doesn’t dissolve the foam is crucial, and Loctite Foam Adhesive has proven to be a reliable choice for sticking foam to itself and other materials. Its thick and gooey consistency allows it to work effectively even when there are gaps between the materials.
In my recent project, I needed to bond a 4ftx8ftx1in foam board to a concrete wall. I applied generous 2-inch “globs” in the top corners, center, and bottom, along with three lines of caulk down about two-thirds of the length. The bond created by the Loctite Foam Adhesive was excellent!
I was pleasantly surprised to find that I could get more than two sheets per tube, closer to three. Although some of the older tubes I had started to separate, I simply discarded the first few ounces of caulk that were separated, as they didn’t hold well. Once you get to the good caulk, it works perfectly. The adhesive is also easy to clean off hands with water, which is a plus.
Although primarily designed for bonding foam board, I’ve also found this adhesive useful for attaching polystyrene acoustic diffusers together. It’s a versatile product that proves its worth beyond its intended purpose.
However, I must admit that it can be a bit messy when it comes to using it with a caulk gun. The adhesive tends to keep oozing even after you’re done applying it, regardless of whether you retract the plunger or try to block the nozzle. To tackle this issue, I’ve learned to keep a putty knife handy underneath the caulk gun to collect the excess adhesive.
Now, there’s something important to note if you’re placing foam board against a wall that might have even the slightest chance of leaking or sweating. It’s crucial to avoid applying the caulk in a “squiggle” pattern, as it could potentially catch and hold moisture. Instead, I recommend running the caulk lines straight down or in a constantly dropping zig-zag pattern. This way, any water that finds its way in will always have a way out.

Specialized Foam Formula 🛍️ DAP DynaGrip Foamboard Adhesive
In terms of adhesion, this adhesive is exceptional. However, I must mention that their claim of it being ‘easy to gun’ is a bit ambitious. I’ve encountered issues with about half of the tubes I’ve used, as they had an excessive amount of bubbles, resulting in gaps, sputters, and uneven flow. Nevertheless, when the adhesive is free of air pockets, it applies smoothly with steady pressure. It spreads evenly and adheres well once pressed into place, although it tends to slip until you can secure it.
To test its effectiveness, I used this adhesive to bond Pink Foamboard to the inside of plywood siding, leaving a small gap for later filling and sealing with expanding foam. I created foam wedges from the leftover scraps of the foam board panels and strategically placed them to provide support.
Next week, I plan to apply a spray foam sealant to further enhance the insulation in the shed-to-house project I’m working on for my eldest and their small family. Since the cavities are open at the front, I don’t anticipate any major issues, except for a narrow gap I initially started with. Overall, I’m eager to see how well this adhesive holds up to the application of the spray foam sealant.
One thing to note about this adhesive is that it takes over 24 hours to cure fully. During this curing period, I found that the foam board tends to move, which can be a bit frustrating. However, I’m planning to try polyurethane (Gorilla) glue for my next project as it offers a faster cure time and is known to be compatible with foam board. I’ve had some disappointments with other products from this company in the past, but I’m hopeful that the polyurethane glue will be a better fit.
Flexible bond 🛍️ Loctite PL Premium Polyurethane Construction Adhesive

Just by following the instructions carefully, I was able to achieve a solid and permanent bond. It held up incredibly well, even in challenging conditions.
But it wasn’t just limited to concrete repairs. I had a wobbly toilet that needed to be securely mounted to the floor, both for safety and to keep the wax seal intact. While silicone caulk or tile grout might offer temporary fixes, I knew I needed something more reliable. That’s where the Loctite Construction Adhesive came in. I carefully applied it between the toilet and the floor, ensuring a clean application.
In addition to its excellent performance with concrete and toilets, I even put it to the test on a ceramic cat figurine that had been broken. Superglue failed me, but the Loctite Adhesive came to the rescue. After a day, the statue was as good as new. I was impressed by its versatility and ability to bond different materials effectively.
