Acoustical Caulk (29 oz) 1 Tube with clean up wipe

So I put this on my bedroom window because my 10 pound chihuahua is scared of fireworks and I saw all the reviews of how it blocks out the noise, well last night around 1am someone set off fireworks and I could barely hear the fireworks and she didn't hear them she didn't jump off the bed and slept through the fireworks I did put it on the outside and inside of the window and I put it all around the window on all of the trim boards. Its easy to use you just have to go to home depot and buy a bigger caulking gun (doesnt fit standard one) for it, their is no oder and its worth the money, will definitely buy again if/when needed, And will be recommending to everyone i know..

I bought 2 tubes for a green glue premium brand product. What I thought was supposed to be green came as a white mastic. The plastic moveable end that squeezes the glue out wasn’t in the tube properly. The label on wrapping also said it was made by someone else. I found this most peculiar given the tubes were “green glue” but differed from one another. Weird.

Bought this to help out the neighbors, in-wall speaker install on an exterior wall. Only thing left behind the speaker was styrofoam/stucco. Put 1/4" birch in (the most the speaker clearance would allow) and used this to seal it up air tight. A thin layer of dynamat on top of that as well. Anyways, hard to say how effective it was on its own, but it's certainly much quieter now after all that! It was very easy to use, good adhesion and reasonable pricing. Of note it's a rather large bottle, I didn't have a caulk gun big enough for it but I just summoned mantuition and used a hammer to push it out the back so to speak.

This stuff dries super slow and the final consistency is that of modelers putty or firm playdough. I would imagine that is intentional as I suspect that consistency is why it absorbs vibrations in the air (Sound) so well. This also leads me to imagine that I could have shoved playdough or modelers putty in the crack and gotten the same results. Needs special care if your gap is more than very small crack or vertical. It will try to run out of the gap if not watched closely and corrected for a few days. Taking a heat gun, or blow dryer and using that to create and maintain a partially dried shell across the front of it while the center sets will hold it in place but you need to do it multiple times as whatever they use as solvent for this stuff that keeps it liquid will spread from the center and re-soften the outer shell until everything sets. I used a heat gun and imagine a blow dryer would take ALLOT longer/more effort. Just don't totally cook it, standard heat gun rules, keep moving at all times to avoid hotspots. As far as performance now that it's been about 2 weeks and is as set as I think it will get? Well, softer than expected but is totally staying in place in a quarter inch gap, though my initial application was a mess when I walked away for about 3 hours came back and found out the top part of it has slid/poured out the bottom. (Scraped the mess up then wiped with paper towel, EASY to clean up before it sets. Refilled the top, then applied heat to set a retaining shell.) It does seem to have created a world of difference as far as sound deadening. This quarter inch gap was next to a poorly installed AC unit in a new apartment near a very busy road. No maintenance couldn't fix it, they are totally incompetent and the ones who installed the AC unit with enough space beside it for even the largest of cockroaches and other insects to climb right in. It has both sealed the gap decently, and also cut the noise back by allot. I do not know if sealing this with more traditional caulk would have had the same effect, no way to test. All in all I am satisfied but the seller/producer could offer tips and advice for working with this stuff in either a pamphlet or on the product page. Would use again in the future.

I just got the acoustic caulk. Open the box and found the plastic bag open on one side and the nozzle missing. I contacted the seller and was kind enough to mail me one. Now I have to wait to find out if the product will do as advertised.
