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.

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.

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.

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.

If only we could go back in time to stop this disaster which made a bad problem worse in our condo. We are sandwiched between two demon neighbors and did over a year's worth of research on how we could deaden their inconsiderate behavior at all hours. We went with green glue and all recommended sealants as well as 5/8" sound deadening drywall. Because we are not able to reach all parts of the walls and frankly didn't want to, we dropped 10k (a middle of the line estimate) on buying the materials and labor for soundproofing both party walls on all three floors and the smallish wall that surrounded the patio slider. (Condo is 1000 sq ft) We heard zero difference. Actually that's not true, it took what were annoying sounds and isolated then amplified them into thuds. Given the rave reviews, this was completely out of left field and after giving it the 2 months time to supposedly become some super sound deadener, it didn't happen. We have never regretted a decision more in our lives and add to that the contractors got it everywhere and ruined the carpet on both sets of stairs, we are still finding it on doors, handles and anywhere they touched that had the slightest bit of GG on them. So from our experience, I would say run, do not walk, away from this idea you're reading reviews on. The toll the failure of this and the other products used for this has taken on my mental health is considerable. I'm hoping others don't have my same experience and was really hoping to be one of the rave reviews as well.
