Green Glue Noiseproofing Sealant - 12 Tubes

This product really help to reduce the sound, when adding it between two pieces of sheetrock please follow the instruction and it will be okay.

product is one valuable piece in my attempt to soundproof my condo. I have used it between Quiet Rock and around outlets and at the tops and bottoms of the drywall—anywhere sound can pass through. Product works as described but you must allow time as it says in the product description. Can be messy if you are not careful with the glue gun.

From my research, this product is designed to be used between drywall containing a separation instead of mud filled corners. Doing so likely requires covering the caulked gaps with some sort of trim boards. The gaps also likely need to be consistent or eye pleasingly straight, rather than just pushing a mass of (hot) mud into the ceiling corners!STINKYThis stuff really stinks up the room compared to other caulks on the market nowadays having less VOC content. Also, this caulk requires a longer dry time when filling in gaps larger then 1/8-1/4 inches. Only 1/16 inch layer will dry within ~24 hours.COSTCompared to standard "Sherwin-Williams 850A Acrylic Latex Caulk 10.1oz" @ 1.69 a tube, an equivalent amount would require ~34 tubes for a total cost of $57.46. However, acrylic/latex will likely shrink or may crack, compared to this product here.MATERIAL CONSISTENCIESI believe the Green Glue caulk and other Green Glue materials are silicone based containing likely petroleum based products. Spend a little more and purchase a cheap box store silicone caulk, might get you just as good as a seal with similar shrinkage compared to this product. However, a Sherwin WIlliams silicone caulk tends to be twice as much as their acrylic latex caulk, in which case might be best to just purchase a product (such as Green Glue caulk) already having a sound rating and designed for defeating noise due to it's engineered mass.BOTTOM LINEIt stinks, really bad, but based on price comparison with similar products I would likely purchase again unless I'm constrained by budget or interior air quality issues. If you are engineering/constructing a designated sound proof area, go for it, and just prepared to deal with the stink and long dry times. If you're just being cautious with noise, have no time available for dry times, or have poor air circulation for resolving the stink while the caulk dries; can likely either use a basic acrylic latex caulk (~50% the cost of this product) or siliconized acrylic at ~75-85% the cost of this product.

Used this on drafty windows, doors, and wall cracks!This thick, noise cancelling, tubes of greatness are worth every dollar.Yes, theses are big boys and you need a big girl caulking gun.Just not to hear your neighbors, to me is priceless!

I tried several acoustical caulks. These tubes were by far the most consistent. Good quality. Expect some shrinkage.

Horrible, unusable product. Purchased two boxes of this sealant for a two layers of 5/8 Sheetrock job for my ceilings. If your gaps between sheets of drywall are more than 3/16” you are screed. Sealant is so liquid, that it is falling right back on you, on walls and in a floor in a minut or two. But if your gaps are like 3/8”,it is falling right back. Instantly. You need to grab your putty knife and start “sparkle” it right back into your seams. 3/16” gaps doesn’t looks good too after two day of drying.. Suffered for two complete workdays. Sheetrock gaps looks horrible. This useless sealant goes back to Amazon tomorrow. Complete waist of time, effort and money. Putting this materials in to a fridge for overnight doesn’t help at all. G-d only knows how I’m going to go over this stuff with paper tape and joint compaund.

Works as described. I have used this during the construction of multiple recording studios; and it has yet to disappoint. This is the sealant not to be confused with "Green Glue" which is used inbetween courses of drywall.
