Spray Adhesive Recomendations

Hello all, Well construction on the new home and studio has been complete for about six months now and prior to moving in all the gizmos gadgets and hundreds of feet of cable, I mounted my foam to the walls with a spray adhesive (generic spray adhesive that is). The kind that comes with a bundle of foam off ebay. Thinking all adhesives were alike I mounted probably around 320 square feet of foam with this stuff and now.... you guessed it... it's all coming loose and falling off. Now just to test my application, I remounted one entire wall about 6 weeks ago using the same spray (tons of it) and it is coming off again. So I'm convinced the spray is crap seeing as how it was basically free with my order.. Now comes the hard part. I need to remount all the foam in the room with a spray that actually holds and will last for years upon years and here's the kicker... I don't want to diconnect every piece of equipment and move it all out just to put the foam back up. So I need a spray that doesn't have a huge "mist" to it. The thicker and webbier, the better. So I'm just wondering what everyone's experience was regarding foam mounting, and what you'd recomend in this situation. Thanks! -ToneMonkey

Im going to make a prediction............someone is going to say get rid of the foam! :lol: Foam is a 4 letter word around here, especialy the EBAY stuff so just be prepared. It could be that the adhesive was old, or the walls are dusty, or the foam absorbed it like a sponge or a combination of all. Tons of other options though, Liquid nails would be your best bet. I think Musicians friend ships liquid nails with all the foam they sell. You can get it at a hardware store and apply with a caulk gun. Id probably put it up with thumb tacks! At least they could be easily removed if you wanted to liven things up a bit or when you get schooled by the pros on this forum to build your own DYI absorbers..........They schooled me! Im an absorber building fool now!

Depends on your walls, they might absorb the adhesive too much. You need to finish them with some stuff I don't know the Enlish term for :oops: (in dutch it's called Voorstrijkmiddel) it's to prefend the wall sucking all the adhesive.. What kit is it? What walls? photos? (ps. any luck you took some of your construction stages? if so, post'm here, we love'm !)

IF you were ever happy with the sound of your room and want to actually KEEP the foam, I second the Liquid Nailz suggestion - if you have a LOT to attach, it may be cheaper to buy the LARGE caulk gun and get the 29 0z tubes of L-N - you get 3 times as much per tube, and it's only about half again the cost per tube usually. If you were NOT that happy with the sound, or if your foam isn't a big name brand, you may want to at least look at natfire.com for fire retardant spray, and (as Carp says, maybe go the DIY route...

Did you follow the directions on the spray adhesive EXACTLY? Most of the spray on adhesives I've seen (Auralex, Scotch 80, etc), require you to apply the adhesive to BOTH items to be glued together, wait at least 60 seconds, and THEN put together (or press on the wall in your case. If you don't want to just spray a bunch of glue on the wall and hope it's in the right place/shape for your foam, spray an excess amount on the foam the very quickly press the shape against the wall so that some of the glue comes off and sticks to the wall. Pull the pieces apart and wait one minute, then reapply. As to the spray pattern, there should be an adjustment on the top of the can (moving the nozzle left and right) that adjusts the spray width. len

If you try Liquid Nails, test it first; some versions of it will dissolve certain types of foam.

This stuff is unbelieveable. $11.99 at Lowes. 1 of these cans mounted about 10 x 4 Sonex for me. Shortened Link (The method of making those long links NOT force everyone to scroll all over the place is located in the "don't even THINK..." post at the top of every forum - Steve)
