Green Glue Noiseproofing Compound - 6 Tubes,net wt 28 fl.oz(828 ml)

We have a bathroom shared by a guest bedroom and an office - one wall is adobe blocks, the other is a much later stud and thin (1/2 in) drywall partition with a badly fitting hollow-core door. The sound transmission through the newer wall was as if the wall was not there ... anyone using the office would swear that the toilet was right behind their chair.After some internet searching, we decided the most cost-effective plan was to add a layer of thicker drywall and a Green Glue sandwich layer to cut down the noise.FIRST DISCOVERY! The existing drywall was not properly screwed to the partition studs. The sheets had a few screws across top and bottom and just tape and mud along the edges. It was a huge sound transmitting drumhead. So the crew screwed it down according to standard practice. If it had been that way from the beginning, the noise transmission might not have been so bad. If it had been thicker drywall it might not have been so bad. But it was cheaply done by idiots.Anyway ... the crew cut 5/8 drywall panels to fit, tested the fit, then applied the glue and attached the panels over the old wall. They had never done it before but making overlapping "Twinky frosting" loops and screwing on drywall was within their skill set. We used about 2 tubes per 4x8 panel, following the application instructions. (What a radical concept!)Because of a shipping error (see my seller review), we had two tubes of the sealant I didn't order. The crew used it like caulk all around the edges of the wall, in the gaps of the door framing, and in the panel seams.The immediate noise reduction from properly attaching the original drywall and adding Green Glue and 5/8 drywall and sealant was excellent ... I can't hear the toilet tank refilling any more!We still have to apply new door trim and close off the BIG gap at the top and bottom of the door that is now the main source of noise. A properly-fitted, perhaps weatherstripped solid-core door will be installed.PROJECT NOTES: Some quirks of the house construction that helped the noise reduction are ... most of the walls are solid adobe block extending to ground level with each room having independent joists holding up the floor inside the block walls. The added partition wall sits on the subfloor with the finish floor installed later and now caulked for bug reduction. The partition on the office side extends above the bathroom ceiling. The bathroom HVAC duct is an independent branch off the main line, so we don't have duct transmission. The ceilings are plaster and lath and the attic space is full of insulation.The sound transmission as a vibration through the flimsy partition wall was the source of most of our noise. We don't have bypass routes.We read the directions, watched the video and followed the instructions about quantity and application method.

It's been a year since I purchased this product and I couldn't be more pleased. I was attempting to sound proof a section of my basement to stop the loud noise of my band and read about this product on a "how to" web sight. When you compare the price of Green Glue to sound proof drywall it is a bargain so I gave it a chance. I used two tubes for every 4x8 sheet of 5/8" sheetrock. We can play at full volume and you can hardly hear a peep outside and I believe what you can hear is leaking out of the ceiling as my house is very old and I was uncomfortable with how much extra weight two pieces of sheetrock would add to the floor joists. I found it took around three months before I noticed optimum sound proofing but the results were satisfactory from the get go. I guess it can take time to set up. Would be great for people who share a condo wall with a neighbor. One final note: I did a decibel test after putting up the first layer of sheetrock then did a couple other tests after using Green Glue and another 5/8" layer of sheetrock.

We used this for sound proofing in a wall between bedrooms. We followed the directions and watched a few videos before applying. The first 2 tubes applied as expected, no issues. The only problem we had is that the bottom of the 3rd, 4th, & 5th tube we used would blow out as we cut the tip off, we made a huge mess on the floor the first time that happened, then didn’t know what to expect after so we opened them over the Sheetrock and were able to contain the mess and spread it around. It cleans up easily while it’s wet with water and paper towels. I think this happened because we didn’t tap the tube to get all the product to go down before we opened them. We just applied it but it’s already much quieter between the bedrooms with the 2 layers of sheet rock and this between! Despite the mess I would buy it again because we have already noticed a difference is sound barrier

I bought this on recommendations of sound proofing sites as the last thing that can be done after triple insulation, hat channel, 5/8th drywall --leaving 1/8" all around drywall. This stuff was supposed to "fill" those spaces.It dribbled down the walls, was impossible to clean up and impossible to keep in that 1/8" gap. Now it's possible I might have bought the wrong product. But this stuff--not useful for anything. It's so runny that you can't apply it to anything.So I'm on an island with a 6-pack of this useless stuff and a special giant caulk gun. I won't be able to sell or give it away to anyone on the island. What a waste of money. I'm sure I'm passed my return time.

We bought this to soundproof our home's bedrooms so we don't have to worry keeping the home quiet while anyone is sleeping. It is really great. The manufacturer recommends 2 tubes per 4x8 drywall panel. They say applying one tube will give you 70% less noise dampening than 2 and that applying a third will give a slight added benefit. Anything more than three, they say won't add any benefit. So, we tried 1 tube per 4x8 panel in one room and 2 tubes per panel in another room. It takes around 7 days to cure and for maximum sound deadening to occur. The room we used 2 tubes per panel in is way, way, way more soundproofed. I wish we had not experimented with one tube per panel, because it is way less effective. We also did it in our light sleeper's room :( We'll probably correct the problem by Green Gluing some drywall to the other side of the walls of that bedroom.Our next experiment is to compare it to Roxul soundproofing insulation in another room. I'll update this post once we do.For now, I totally recommend this product for soundproofing. Only, use the 2 tubes per sheet of drywall like the manufacture recommends.
