Kirk Dietrich 0 Report post Posted May 27, 2013 Is the 3M spray adhesive the best thing for gluing sheets of foam together? I can't find any information on it being waterproof but I've heard people recommend it. Kirk Quote Share this post Link to post Share on other sites

flysmallie 0 Report post Posted May 27, 2013 The 3M adhesive is waterproof. It's good stuff. Quote Share this post Link to post Share on other sites
heavynets 0 Report post Posted May 27, 2013 3M makes several different spray-on adhesives. The specs for 77 say it's moisture resistant, but I've not had a problem with it. http://www.homedepot.com/p/3M-Super-77-16-75-fl-oz-Multipurpose-Spray-Adhesive-77-24/100067550#specifications Quote Share this post Link to post Share on other sites
Fish For Life 0 Report post Posted May 27, 2013 I use contact cement. May not be the fastest drying glue in the world bu im in no rush and i know my foam has no chance of coming apart. Quote Share this post Link to post Share on other sites
Kirk Dietrich 0 Report post Posted May 27, 2013 Kevin, when you say you use Aileene's and haven't had a problem with it, that means you've fished laminated foam sheet bugs and they stay together? Pete, like Heavy Nets said, I think you'll find on the can that it says water resistant. That is what got me wondering as most things that say resistant aren't waterproof but it seems like that could be different in this case as Flysmallie seems to be attesting to. Fish For Life, are you using the commercial contact cement for laminating formica to make countertops? or the Elmer's craft rubber/contact cement?

I use LePage contact cement. Its great stuff. I use it for foam pike flys and they have all survived the toothy critters and the water. Quote Share this post Link to post Share on other sites

I spread it thin and lay something over the stack. I make my poppers with it. Kevin Quote Share this post Link to post Share on other sites
carlp5351 0 Report post Posted May 27, 2013 Spray 77 works great, tons of hoppers tied and fished with it, no problem. Quote Share this post Link to post Share on other sites
Piker20 0 Report post Posted May 27, 2013 funny how a hundreds of miles away another tier is having the same problem. I will need to try to find some UK glues that match the US ones but I haven't had much joy with the glues I tried before. The 3m has lots of positive feedback and available everywhere.

BuzFly 0 Report post Posted May 27, 2013 3M Spray Mount 77 or Contact Cement will all work well. I find if you lightly coat both sides and let them almost dry completely then assemble the layers you get better adhesion. When I was doing a lot of theses I made a simple jig. Most sheets are about 9x12. I cut a piece of scrap plywood about 11x14 and two pieces of scrap one 11" long and the other 14" long less the thickness of the scrap. Then attach the scraps to the edge of the board forming an "L" This will be used to help guide you when you put the sprayed foam together. Once you assemble the sandwich put a bunch of weight on it over night and you will be good to go. If you have another scrap of plywood, cut one a little bigger than 9x12 and put that on top of the foam before you put the weight on it. It will help distribute the weight better. Yes I know I have to much time on my hands........ Brad PS: In a pinch you can use the Sticky Foam but it won't last that long. Quote Share this post Link to post Share on other sites
Piker20 0 Report post Posted May 27, 2013 Well Kirk, look forward to seeing what you make with all this foam or are you making armour for kids parties again?? Quote Share this post Link to post Share on other sites
Kirk Dietrich 0 Report post Posted May 27, 2013 Thanks for the feedback guys. Yeah Piker, I've just never been happy with the different things I've used. The best luck I've had is the flexible CA by BSI but it is thin and you have to put a seal coat first and you have to use a bunch. Then, I've used Barge cement but that stuff turns yellow. You won't see anything ground breaking from me with this, just want to start making more foam bugs and some Rabid Dogs with the soft foam. Cut one out of the foam I got from Sleazy Steve's and made one and it works great. Kirk Quote Share this post Link to post Share on other sites
Prosopium w. 0 Report post Posted May 28, 2013 I gave up on spray type adhesives....way to messy and troublesome. I now use the two-sided tape used for hanging plastic in windows in the winter. it is more convenient and is nearly (or just as) durable as the adhesives I've tried, which include the ones listed. That said, I must admit that I usually only use foam like this for Morrish-type hoppers. Quote Share this post Link to post Share on other sites
