I will be installing sound dampener over this weekend. The deamplifier already has adhesive on the backside of it but the overkill closed cell foam needs an adhesive to mount. I know 3m makes some kind of paste adhesive that I could brush on but I'm not sure of the name of the product. Any ideas of this product or others are welcome, thanks!

 

I applied the acoustic foam over B-Quiet Ultimate sound deadening throughout my S - under the carpet, inside the doors, on the back of the door panels, and all metal surfaces of the trunk.

The adhesive i used was a 3M aerosol called Foam Fast 74 . It is pretty easy to direct it into areas without over-spray. Actually it comes out of the can like string glue. Put it on both surfaces and let it dry a little and then press into place. For sheet metal areas you can't reach, spray excess glue on the foam and put it into place, then remove it for a couple of minutes and then put it back.

This glue dries quickly and the smell does not linger.

Closed-cell acoustic foam is incredibly cheap and incredibly effective for sound deadening (it is also very light for those watching their weight).

Have fun!

 

which foam is it? ensolite foam?

according to rick at raamaudio. the best adhesive he has used is the one he sells. according to him, leagues ahead of the 3m super 90.

scroll to the bottom V&S 1081 its called.

i have not tried it yet, but i have it on order right now.

 

Yes, it is Ensolite. I bought it by the yard from a commercial upholstery supplier. They call it "Landau foam". I used the 1/4" thickness for most of the application, and 1/8" foam for areas where the carpet fasteners go.

The adhesive product I used is 3M 74 , not 90. It is very tenacious - something you want in a vehicle exposed to temperature extremes as well as vibrations. I've used other brands in the past that just didn't maintain a grip over time. I've always had good luck with 3M products.

But, I haven't had any experience with the V&S brand.

VintageMac:

Where did you purchase the 3m foam fast 74? Would a local hardware store (lowes, home depot) carry this stuff?

Thanks

 

I bought mine at the upholstery supply outfit where I got the foam.

However, I have also found it at my local (well-stocked) True Value hardware store.

 

how much did you guys pay for the ensolite?

 

The Ensolite (closed cell acoustic foam) comes on a large roll. It is 60" wide and you can buy as many lineal feet as you want. One yard (15 square feet) of the 1/4" foam was $7.80 or $ .52 per square foot.

The 1/8" foam is $7.00 per yard or $ .47 per square foot.

The 3M Foam Fast 74 was $14.35 per can.

 

thanks

 

I got my foam and sound dampening mats from http://www.secondskinaudio.com/ -- They were supposdly the best product you can buy and my baby doesn't deserve anything less then the best
