It will, without a doubt, be successful. Perhaps a tad too much. Because the spray becomes less even over time, I'd recommend starting with a new bottle to ensure an even surface with no minor bumps.
As long as the adhesive doesn't react with the foam, which I don't believe it will, it should work fine. I'd apply the adhesive thickly to get a smoother surface that will be easier to work with.
I've used other 3M spray adhesives that are better than this one, and it stays tacky for a long time. This one does not sit well with me.

Because our supplier is discontinuing the natural rubber-based glue we've used for 20 years, I bought eight different contact adhesives to try out for use in my business. I used a weathered piece of lumber and polyethylene foam to glue to it because we needed a quick acting permanent bond. Yes, the wood is extremely rough and contains embedded dirt, and LDPE foam is one of the most difficult materials to glue, but the current glue we use and sell would permanently adhere both of these items. br>br>The 3M 77 is a version of the same stuff we use, and it's been around for a long time, but they still think it's worth gold in terms of price. It was ruled out and only included in the mix if no other less expensive product worked as well or better.
This is what I used to replace the headliner in my car.
What a waste of time. After reading the positive reviews, I decided to purchase this to replace the headliner in my truck. What a waste of time. After spending hours removing the headliner and scraping away all traces of the previous liner from the truck. I installed the new material and followed the directions to the letter. The fabric started to detach from the liner two days after I installed the new headliner. I took it down and did it all over again, this time saturating the fabric and using a roller to ensure proper adhesion. The same issue arose two days later. This was done with a felt fabric that adhered to everything else I tried well.
This adhesive spray was used to adhere acoustic foam to chipboard, but it only lasted about 60 square feet before it ran out. I ran out of time before completing the task. This is a single product layer on a single substrate. I also had to check that the adhesive was "aggressively tacky," which required a timeframe of 10 seconds to 10 minutes, which is a completely useless figure. I contacted 3M directly, and they couldn't even give me an estimate for how long it would take because "substrates, temperature, humidity, and amount of adhesive applied" all seem to vary so widely. Also, this is the clear version of the adhesive; I anticipated being able to see some white adhesive down and it gradually curing to clear. This isn't the case, however: It applies completely clear, making it difficult to see where you've sprayed unless you have the right lighting. br>br>Once the spray had become aggressively tacky, I put the boards together, and despite the spray's claims to the contrary, it wasn't really adjustable. Without tearing the foam, the pieces would not budge. I thought I'd be able to align a 1' square piece of foam with a 1' square piece of chipboard, but the adhesive wasn't as adjustable as it claimed, so I had to cut the boards off the foam, then cut all of my boards to be smaller than the foam pieces and place them on without adjusting them. I noticed that only some of the boards were adhered to the foam when I was removing them from it. There were foam-free zones in some places. Some areas, such as tearing strength, and others, were incredibly easy to separate. In fact, because the chipboard was so warped and the adhesive was so weak, some of the corners peeled away from the foam without my assistance. I'll disregard the warping because it was caused by moisture issues unrelated to the adhesive. During the warping, however, the adhesive was unable to keep the soft foam attached to the boards. br>br>Overall, for $11, it's a decent and affordable adhesive for acoustic foam and chipboard; just keep in mind that it's not adjustable, you won't get much spray, your aggressive tack time will be somewhere between 10 seconds and 10 minutes, and you won't be able to rely on it to hold uneven surfaces to soft foam. br>br>Creative+ paraphrase: The acoustic foam pieces that I'd hung up had started to fall down after a while. In order to develop a more permanent bond, I had to tape off areas of my wall with painters tape and newspaper, spray the spray onto the chipboard that was still adhered to the wall (with 3M's Command Strips), and spray the foam itself. So far, they haven't fallen again. Spray both the foam and whatever you're attaching it to for long-lasting adhesion, especially with foam.
It's possible to use acoustic foam in this project! It dries very quickly. It stinks bad at first, but it goes away after a while (it is, after all, glue). Just make sure it's in a well-ventilated area when you use it. The only criticism I have is that the spray is difficult to control. It spreads widely and gets all over the place, so if you're working on a surface, protect it with a trash bag or something.
It was purchased for the purpose of applying acoustic foam to walls that had been painted with top-coat paint. Sherwin Williams paint is of the highest quality. br>First, I applied a thin coat to both surfaces. I put up the foam, waited the recommended amount of time for tack, and it was on the ground the next day. br>Today, I put in a lot of effort on both surfaces. When I first put it up, it snatched my attention and I had to fight to get it down. establishing a position Although the job appears to be in bad shape, I was hoping for a positive outcome. It isn't the case. After a few hours, the foam chunks begin to lift from the walls. br>I'm going to be *really* angry if this ruins $300 worth of foam. br>Shame on you, 3M, for putting out such a bad product.
I bought this adhesive to go with the new headliner I bought to replace the headliner on my 2003 VW Jetta. At first, everything went as planned- sprayed the cleaned headliner board as well as the headliner I bought a couple of rollers to help me apply the headliner to the headliner board, and I used about a half-dozen of them. 5 cans of 3M spray-on degreaser For the size of the job, this is more than sufficient. br> After about an hour and a half, you should be able to see what's going on The new headliner began to sag from the headliner board after only 7 days. br>I was disappointed because I expected a 3M product to perform better.
I'm about to place an order for another 2 yards of headliner fabric as well as a different glue. On the second day, the glue began to come loose. The headliner is coming down all over less than a week later, on the first day out in the heat. Even a small spot with a slight wrinkle that I couldn't get loose when I first glued it came loose yesterday. I've been an auto body technician for nearly fifty years, and I've used a wide variety of materials for almost every automotive application. My time and money were both squandered by this glue. If it's useful for anything, I'm not sure what it is. It is ineffective for headlines.
