Latex Based Driveway Sealer For Damping Drywall?
I am pretty much done with soundproofing my basement but want to apply something to the last layer of drywall in order to increase it's damping ability. I found some industrial vibration damping compound used on machinery and rv type stuff but it is very expensive!!! I was considering applying a few layers of the liquid roofing asphalt sealer stuff but I am sure this stuff stinks so I don't know. I wanted to use it because it dries flexible almost pliable which makes me think it would damp some vibration. I also noticed a latex based driveway sealer that has some asphalt in it. I think its called Latex-Ite and it doesn't contain any solvents or anything too nasty. From the few dried bits on the side of the pals it seems like it dries pretty hard, not like the roofing stuff. So does anyone have an opinion on using this Latex-Ite sealer on the walls? I don't think it would eat through the wall I hope? Are there any other common roll/brush on materials that I could use? I am sick of measuring and cutting pieces of different materials and then sealing them. I just want to roll something on at this point. Thanks

the core reality of damping drywall is that drywall is pretty thick/stiff stuff.
damping materials put on top of things are generally called extensional damping materials, and tend to fail when trying to damp stiff things.
damping materials put in between two stiff things like an adhesive (also come in pad form, but same principle) are generally called constrained layer damping materials...
those can damp stiff things.
try it yourself: take a panel of drywall perhaps 12-24 x 20-35"... whatever.
make 2 such panels. paint some of that stuff on at 100 square feet/gallon. let it dry.
hold them loosely in a hand and tap them with a knuckle. at that thin of a layer, even a material designed to be a damping material would struggle mightily to elicity meaningful changes.
then try the test above again, but with 1 gallon/sheet of drywall. then try again at 5 gallons/sheet of drywall. lol

i posted a bit about this in a thread below a week ago or so, and the thing to remember is that damping is measureable, and if you can't measure a big change in the damping of your drywall sheet, whatever you're spending is money wasted.
but a cool idea, and a cheap product, and if it did something that might be a good thing.

in any case, titanium fortified probably just means it has some white pigment.
other titanium fortified things include basically all latex paint, some underarm deodorants, some shampoos, and toothpaste

One more layer of toothpaste and I'm done!!! Am I the only person who dreams of liquid rubber in a pal?
Yeah I see what you are saying it's stiff but i can tell it resonates especially when it comes to structure borne sound (vibration) coming into the room. I guess it wouldn't do anything significant unless I built up a layer of "liquid rubber" that was at least as thick as the drywall. I'll try some tests and check out that link. Thanks
