Green Glue Noiseproofing Compound - 5 Gallon Bucket

So excited for how well this worked. I screamed from the top of my lungs from the upstairs apartment and they couldn't hear a thing downstairs. I have a single-family residence that I split into two apartments. Per the recommendation of other reviews I used this process in layers starting closest to the cealing upstairs. 5/8 drywall against the floor of the upstairs, green glue, green glue noise sealant, then another staggered 5/8 drywall. Hat channels, whisper clipsn attached to studs, then 5/8 drywall, green glue, noise sealant, and a last 5/8 drywall. 41% spent on supplies, 59% spent on labor. Total project covered 800 square feet. I spent $24 a square foot.

A few people posting that this didn't work for them. The only way that would be true is if they didn't read enough prior. I built the cheapest room I could, single stud 5/8 drywall > roxul > 5/8 drywall > green glue > 5/8 drywall. The most important extra things I did were to seal EVERY single gap during each layer of drywall with soundproof caulk. The intake and outtake for the ventilation was completely boxed in with the same wall setup + padding. There is a MASSIVE difference with the green glue. My compressor and saws are completely silent outside the room. There are a few frequencies that go right through the wall, but it's expected. Love this stuff, will never doubt it again.

I'm renovating a rental apartment, took up all the old hardwood flooring. Secured the subfloor with screws and changed any area that needed changing. I did not pull up the subfloor. After a ton of research I decided to go with green glue compound sandwiched between the sub floor and a 1/2 inch cork underlayment with green glue sealant around the edges. It's kind of messy to work with. This was my first time though. I did the math of how much square footage a 5 gallon bucket covers, based on needing 2-28oz tubes per 32 sft...........but in reality each bucket covered 300 sft. As far as efficiency goes I don't know if it's the cork or green glue or a combination of both, but I have noticed a difference. Gun needed needs to be purchased separately.

So I probably went overboard but I put in a double wall, then insulated both walls with Roxul. I sheeted the inner wall with 5/8 plywood and the outer wall with 5/8 drywall. I smothered another layer of drywall with green glue and then layered that over the plywood. So I now have a sandwich that goes: Drywall : Roxul : Roxul : Plywood : Green Glue : Drywall. I will be adding a layer of straw padding and then finally acoustic fabric. On the ceiling I used 1 layer of Roxul and just two layers of drywall with green glue in between. I made sure the drywall guys used short screws so as to not penetrate through the plywood to the studs. I ended up using 4 x 5 gallon drums of green glue. I used the dispensing gun and filled it twice for each sheet of 12 ft drywall. I think that equates to a little over 2 tubes if you are not using the 5 gallon drums. The theater is about 30 feet by 16 feet. Already there is zero sound transmission in either direction and pounding on the floor above is hardly audible.

I hadn't used the sealed Green Glue for a couple of years after I bought it (renovation had to be put on hold). When I opened the bucket for the first time a few months back, there was some separation and very watery type liquid at the top. So I used a mixer on my drill to mix the Green Glue back to its original consistency, and then used very little for the small project I was working on, and sealed the bucket. Today, when I opened the bucket to use some more, there was black mold spots on the top layer of the Green Glue. I immediately sealed back and now have to throw out. Still over 90% unused! WHAT A WASTE OF MONEY!!! Never added anything to the Green Glue; only stirred it with a mixer that one time. VERY DISAPPOINTED!!!

Great value for your money, quality instruction carefully and it will do what is set out to do, pretty good on health reducing sound through walls when Dublin sheetrock.

Helped improve noise reduction between floors. I used it to glue two pieces of sheet rock on ceiling of basement as extra help to reduce noise.

After an exhaustive review of available soundproofing technologies I decided to apply this product between two sheets of five eighths wallboard mounted on RC channel for floor ceiling sounds eparation in an apartment building. An eighth of an inch prrimeter spacing was filled in with acoustic sealant prior to taping and mudding. Having in the past used soundboard, quiet rock, and two sheets of five eighths rock without the green glue, my impression is that this is the superior product. Construction noise such as sawing, drilling, and hammering have become barely audible, seeming to co e in through the windows rather thzn between floors. Regrettably Green Glue is very expensive for what seems to be a non hardening sticky watered down latex pfoduct. If it was cheaper I would use it more often. If there were actual competitors I would use them if the price was better. Because of the cost I give it 3 stars.
