St. Gobain GGCOMPOUND-28OZ Green Glue Noiseproof Compound, 28 Ounce (Pack of 1)

If you haven't ever used this product, there are a couple of things to be aware of. It comes out fast! Don't squeeze too hard. Also, it doesn't set up. As in it doesn't dry. Ever to the best of my knowledge. But it does become VERY sticky. Just something to be aware of depending on how you intend to use it. I used it in a portable application where I sandwiched it between two pieces of plywood. It comes out the ends and gets all over everything. Seems to be a great product.

I liked that it seems to work somewhat but I dislike how long it stays really sticky. This stickiness may be what makes it work to reduce noise from passing through but just saying it stays sticky for days and to immediately clean off any from where you dripped. One other thing is I found that when the tube is empty a lot of wasted product gets left inside the applicator you screw on to dispense the glue. I therefore simply do not us the screw on applicator that is supplied with each tube. This stuff is expensive.

It’s hard for me to review a product like this. I used it between two layers of drywall in a music studio space. The room is very quiet, not perfect, but it’s hard for me to say what the green glue is doing vs the layers of drywall, overkill insulation, two doors with a gap, etc.... I knocked off a star because it’s very expensive for what it is and it’s sticky on areas I’m having trouble removing it. I highly recommend getting the 5 gallon buckets that are more cost effective if you’re doing a room. I only got this cause 2 buckets came up a little short.

The bottom of the tube fell out before I could even load it into the caulking gun. Huge mess and waste of time and resources. Clearly defective product seal.

We had to build soundproofing walls on an entire side of the home (townhouse) because we have a noisy neighbor. These along with the special drywall and sealant have done the trick. I do not hear the neighbor anymore, it really works !
